+# Instructions for stable-diffusion.cpp
+
+This document is for AI coding agents working in this repository. It should
+describe agent-specific workflow, repository routing, editing boundaries, and
+project-specific pitfalls.
+
+For general contribution rules, including PR scope, commit conventions, code
+style, dependency updates, security hygiene, and AI-assisted contribution policy,
+see `CONTRIBUTING.md`.
+
+---
+
+## Agent Operating Rules
+
+Before analyzing or modifying the repository:
+
+1. Read this file.
+2. Use `rg` / `rg --files` or directory listing commands to confirm the current
+   tree before relying on a path.
+3. Start from `src/` and relevant `docs/` for runtime behavior.
+4. Read the relevant code before editing.
+5. Prefer the smallest change that fits the existing architecture.
+6. Report focused verification and mention any tests not run.
+
+Agents must not:
+
+* Run `git push`, create PRs, or submit issue/PR comments on the user's behalf.
+* Create commits unless the user explicitly requests that specific commit.
+* Modify `ggml/`, `thirdparty/`, or `examples/server/frontend/` unless
+  explicitly requested and necessary.
+* Read large local model files or tokenizer vocabulary files.
+* Rewrite unrelated code for style-only reasons.
+* Add secrets, model weights, generated binaries, local absolute paths, or
+  machine-specific output.
+
+When a change is large, architectural, or likely to affect public behavior,
+pause and present a short plan before editing.
+
+---
+
+## Repository Map and Editing Boundaries
+
+This is a routing map for agents, not a full architecture document. The layout
+can change, so verify paths before using them. Do not inspect excluded
+large-data directories while checking the tree.
+
+### Primary Project Code
+
+Core implementation lives under `src/`.
+
+Current source layout includes:
+
+* `src/core/` - shared tensor, ggml integration, backend, graph, RNG, and utility
+  code.
+* `src/model/` - model families and model components.
+* `src/model_io/` - model file loading, GGUF, safetensors, pickle, and related
+  serialization helpers.
+* `src/runtime/` - sampling, denoising, guidance, caching, preprocessing, and
+  runtime execution helpers.
+* `src/tokenizers/` - tokenizer implementations.
+* `src/conditioning/` - conditioning and prompt-related implementation.
+* `src/extensions/` - optional feature extensions.
+* top-level `src/*.cpp` and `src/*.h` files - public implementation entry
+  points, model loading, conversion, versioning, and shared managers.
+
+`src/tokenizers/vocab/` contains large tokenizer vocabulary data. Do not read or
+parse files in this directory; reference the path only when necessary.
+
+### Public API
+
+`include/` contains the C API exposed by the project. Currently the primary
+public header is `include/stable-diffusion.h`.
+
+Treat public headers as stable API. Avoid breaking compatibility unless the user
+explicitly requests it. If public behavior changes, update relevant examples or
+documentation.
+
+### Examples
+
+`examples/` contains programs demonstrating library usage.
+
+* `examples/cli/` - command line program for running models, testing features,
+  and debugging.
+* `examples/common/` - shared example support code.
+* `examples/server/` - server application built on top of the library.
+* `examples/server/frontend/` - git submodule containing independent frontend
+  code. Avoid modifying it unless explicitly requested.
+
+### Documentation and Tooling
+
+* `docs/` - documentation for supported models, build options, behavior, and
+  workflows.
+* `scripts/` - development, model processing, build automation, formatting, and
+  tooling scripts.
+* `cmake/` - CMake support modules.
+* `docker/` - Docker-related project files.
+* `assets/` - documentation assets; not runtime code.
+
+### External, Local, and Generated State
+
+* `ggml/` - git submodule for the ggml dependency.
+* `thirdparty/` - vendored third-party dependencies.
+* `models/` - local model storage. Ignore this directory and do not read model
+  files.
+* `test/` - local testing scripts. Use only when relevant to the task.
+* `build/`, `build_*`, and similar directories - generated build outputs.
+  Inspect them only when debugging a build result.
+
+---
+
+## Agent Workflow for Code Changes
+
+1. Identify the relevant modules under `src/`.
+2. Check whether the change touches the public API in `include/`.
+3. Consult relevant `docs/` and examples before changing user-facing behavior.
+4. Follow existing local patterns before adding new abstractions.
+5. Keep edits scoped to the requested behavior.
+6. Run the narrowest useful build, test, or inspection command available.
+
+Follow `CONTRIBUTING.md` for formatting, naming, PR expectations, dependency
+update policy, and security rules. For tokenizer additions, follow its embedded-data
+allowlist and default to an external `tokenizer.json`.
+
+---
+
+## Code Comments
+
+Keep comments rare and useful.
+
+Do not add comments that only describe what the code does. Add comments only
+when the code cannot fully express the logic, the logic is unusually complex, or
+there are historical reasons, invariants, constraints, compatibility concerns,
+or known pitfalls that future maintainers need to understand.
+
+Do not add task-specific comments that will be meaningless after review.
+
+Examples from the current codebase:
+
+```cpp
+// GOOD: explains a safety constraint that is not obvious from the assignment.
+// From src/model_io/pickle_io.cpp.
+// Non-tensor checkpoint metadata can use REDUCE for arbitrary
+// Python objects. Do not execute it; keep stack shape only.
+stack.push_back(make_none_value());
+
+// BAD: describes only what the next line does.
+// Set the token count to zero.
+token_count = 0;
+```
+
+---
+
+## Text File Encoding
+
+When reading or editing repository text files:
+
+* Prefer UTF-8 with LF for Markdown, frontend source, JSON, and other text-first
+  project files unless the file already clearly uses a different encoding.
+* Do not assume terminal output encoding matches file encoding on Windows.
+* A file that looks garbled in PowerShell output may still be valid UTF-8.
+* When inspecting UTF-8 files in PowerShell, prefer explicit UTF-8 reads such as:
+  * `[Console]::OutputEncoding = [System.Text.Encoding]::UTF8`
+  * `Get-Content -Encoding utf8 <path>`
+* Avoid rewriting a file purely because console output looked garbled; verify
+  the actual file encoding first.
+
+---
+
+## Tensor and Layout Notes
+
+Additional tensor/layout rules for this codebase:
+
+* `sd::Tensor` shape order is not PyTorch/NumPy-style. `shape()[0]` is the
+  lowest and most contiguous dimension, and higher indices are higher
+  dimensions.
+* Broadcasting for `sd::Tensor` must align dimensions from low to high dimension
+  indices. If one tensor has fewer dimensions, append implicit `1`s at the
+  higher-dimension end.
+* `ggml_n_dims` / `ggml_n_dims(tensor)` can drop trailing singleton high
+  dimensions. Do not assume a logical trailing dimension of `1` will still be
+  counted in ggml metadata.
+* Internal tensor-returning interfaces use an empty `sd::Tensor` to represent
+  null, absent, or failure states. Do not add `std::optional<sd::Tensor<...>>`
+  for internal APIs unless a distinct semantic state is truly required.

+# Contributing
+
+This document collects general contribution conventions for this repository.
+
+## Before You Start
+
+Before opening a PR, please search existing PRs to avoid duplicating ongoing work.
+
+For large-scale refactors or changes with broad impact, please open an issue first to discuss the approach before submitting a PR.
+
+If you want to update a third-party dependency, please open an issue first instead of submitting a direct PR. See [Dependency Updates](#dependency-updates) for details.
+
+## Pull Requests
+
+When contributing from a fork, use a fork under your personal GitHub account and enable **Allow edits from maintainers**. This lets maintainers make follow-up fixes directly on the PR branch.
+
+PRs from organization-owned forks are automatically closed when opened or reopened because GitHub does not support this maintainer-edit option for those forks. Submit the changes from a personal fork instead. See [GitHub's documentation](https://docs.github.com/en/pull-requests/how-tos/work-with-forks/allowing-changes-to-a-pull-request-branch-created-from-a-fork).
+
+Keep each PR focused on one clear change. Large or overly complex PRs are harder to review and may not be merged.
+
+Do not include test code or test scripts in commits or PRs. Keep them local and report verification results in the PR description.
+
+Follow Conventional Commit-style subjects seen in history: `feat:`, `fix:`, `refactor:`, `ci:`, `docs:`, `chore:`. Keep subjects imperative and scoped.
+
+PRs should include:
+
+- What changed and why (short problem/solution summary).
+- Verification evidence when applicable (commands and key outputs).
+- Linked issue/PR context when applicable.
+- Screenshots or sample outputs for UI/visual behavior changes.
+
+## Code Style
+
+Format code according to the repository style before submitting changes.
+
+Formatting follows `.clang-format` (Chromium base, 4-space indent, no tabs). Run `scripts/format-code.sh` or `scripts/format-code.ps1` before opening a PR. Keep C++ standard at C++17-compatible patterns used in this repo.
+
+Naming conventions:
+
+- Use `PascalCase` for class/struct/type names.
+- In `PascalCase` names, preserve common abbreviations in uppercase, for example `SD`, `API`, `HTTP`, `JSON`, `RGB`, `VAE`, `TAE`, `LoRA`, and `WebP`.
+- Use `snake_case` for functions, methods, variables, and file names unless an existing API requires a different style.
+- Use a trailing underscore for private data member names, for example `hidden_size_` or `tokenizer_`.
+- Use `.hpp` for model headers under `src/model/`, including new model headers. Do not rename these headers to `.h`. Use `.h` for other C and C++ header files.
+- Use macro-based header include guards instead of `#pragma once`.
+- Format header include guards as `__SD_{PATH}__`, where `{PATH}` is the header path in uppercase snake case without the file extension. For example, `src/sample.h` should use `__SD_SAMPLE_H__`.
+- Do not introduce anonymous namespaces in new or modified code; prefer `static` file-local functions/variables or an explicit named namespace when scoping is needed.
+- In `class`/`struct` definitions, place data members before member functions unless an existing type already clearly follows a different pattern.
+
+Some older code in the project may not fully follow the current conventions. Please do not submit PRs that only rewrite existing code to match style rules.
+
+When adding or modifying model implementations, follow the model config and weight detection conventions in [docs/model_config.md](docs/model_config.md).
+
+## Tokenizer Data
+
+New model integrations must use an external `tokenizer.json` by default. Do not
+embed new vocabularies or merge tables solely for less widely used models;
+these tables increase the binary size for every user.
+
+The embedded-data allowlist is CLIP, T5/UMT5, Qwen 2/3, Mistral, and Gemma 3/4.
+Models may reuse an existing embedded tokenizer when its vocabulary and behavior
+match their text encoder. Gemma 2 and GPT-OSS require external JSON files.
+
+Adding to this allowlist requires maintainer approval, supported by the model's
+usage, reuse across models, and measured binary-size cost. Document the matching
+JSON and CLI option for models that require an external tokenizer, and fail
+initialization clearly when it is missing.
+
+## AI-Assisted Contributions
+
+AI tools may be used to assist development, but contributors are responsible for the quality and correctness of the submitted code.
+
+If any part of a contribution was generated with AI assistance, the contributor must perform a thorough human review before submitting the PR and understand every changed line.
+
+Do not list AI tools as co-authors. The human contributor is the sole responsible author of the submitted code.
+
+Please do not submit AI-generated code that you do not understand, and do not include meaningless experiments, temporary test code, or unrelated generated output in a PR.
+
+## Dependency Updates
+
+Do not submit PRs that update `ggml`. `ggml` updates are performed only after local validation by the maintainer.
+
+Other third-party dependencies are not updated unless necessary. If you want to update a dependency, please open an issue first instead of submitting a direct PR.
+
+## Security & Configuration
+
+Do not commit model weights, secrets, or local absolute paths. Keep large binaries out of git unless intentionally tracked release assets.

+# ADetailer
+
+`sd-cli` can run a YOLOv8 object detector on an existing or newly generated
+image and perform a cropped inpaint pass for every detected object. The first
+implementation supports YOLOv8 detection checkpoints. YOLOv8 segmentation and
+MediaPipe models are not supported yet.
+
+## Convert a detector
+
+Ultralytics checkpoints must be converted before use. The converter fuses
+BatchNorm into convolution layers and writes a safetensors file with the weight
+names expected by the native GGML implementation.
+
+```bash
+python scripts/convert_yolov8_to_safetensors.py face_yolov8n.pt face_yolov8n.safetensors
+```
+
+The converter requires Python packages `ultralytics`, `torch`, and
+`safetensors`.
+Only YOLOv8 detection checkpoints are accepted.
+PyTorch checkpoints use pickle internally, so only convert `.pt` files from a
+trusted source.
+
+## Repair an existing image
+
+Use the dedicated `adetailer` mode to detect and repair objects in an existing
+image:
+
+```bash
+./bin/sd-cli \
+  -M adetailer \
+  -m model.safetensors \
+  -i input.png \
+  -o repaired.png \
+  -p "detailed portrait photo" \
+  --negative-prompt "deformed face" \
+  --steps 24 \
+  --cfg-scale 6 \
+  --strength 0.4 \
+  --sampling-method dpm++2m \
+  --scheduler karras \
+  --ad-model face_yolov8n.safetensors \
+  --extra-ad-args "confidence=0.3,inpaint_padding=32,mask_blur=4"
+```
+
+This mode reuses the normal image-generation options for the detail pass:
+
+- `--init-img`, `--output`, `--prompt`, and `--negative-prompt`
+- `--steps`, `--cfg-scale`, `--sampling-method`, and `--scheduler`
+- `--strength`, `--seed`, LoRA settings, VAE tiling, and backend assignments
+- `--width` and `--height`, which also resize the input when specified
+
+`--ad-prompt` and `--ad-negative-prompt` optionally override the normal prompts.
+Values provided in `--extra-ad-args`, such as `steps`, `cfg_scale`,
+`denoising_strength`, or `inpaint_width`, take precedence over inherited values.
+
+## Repair generated images
+
+ADetailer can also run automatically after normal image generation:
+
+```bash
+./bin/sd-cli \
+  -m model.safetensors \
+  -p "portrait photo" \
+  --ad-model face_yolov8n.safetensors \
+  --ad-prompt "[PROMPT], detailed face" \
+  --ad-negative-prompt "" \
+  --extra-ad-args "confidence=0.3,denoising_strength=0.4,inpaint_width=512,inpaint_height=512"
+```
+
+An empty ADetailer prompt inherits the main prompt. `[PROMPT]` inserts the main
+prompt, `[SEP]` assigns different prompts to consecutive masks, and `[SKIP]`
+skips the corresponding mask.
+
+All settings other than the detector path and prompts are passed through
+`--extra-ad-args` as a comma-separated `key=value` list:
+
+| Key | Default | Description |
+| --- | ---: | --- |
+| `input_size` | `640` | Square YOLO input size; must be a multiple of 32 |
+| `confidence` | `0.3` | Detection confidence threshold |
+| `nms` | `0.45` | NMS IoU threshold |
+| `max_detections` | `100` | Maximum detections retained after NMS |
+| `mask_k_largest` | `0` | Keep only the largest K masks; zero keeps all |
+| `mask_min_ratio` | `0` | Minimum bbox area relative to the image |
+| `mask_max_ratio` | `1` | Maximum bbox area relative to the image |
+| `dilate_erode` | `4` | Positive values dilate; negative values erode |
+| `x_offset`, `y_offset` | `0` | Mask offset in pixels; positive Y moves upward |
+| `mask_mode` | `none` | `none`, `merge`, or `merge_invert` |
+| `merge_masks`, `invert_mask` | `false` | Boolean alternatives to `mask_mode` |
+| `mask_blur` | `4` | Final composite feather radius |
+| `inpaint_padding` | `32` | Padding around the detected region |
+| `inpaint_width`, `inpaint_height` | mode-specific | `512x512` after generation; input/output size in `adetailer` mode |
+| `denoising_strength` | mode-specific | `0.4` after generation; inherits `--strength` in `adetailer` mode |
+| `steps` | `0` | Detail steps; zero inherits the main generation |
+| `cfg_scale` | `-1` | Detail CFG; a negative value inherits the main generation |
+| `sample_method` | inherited | Detail sampler name |
+| `scheduler` | inherited | Detail scheduler name |
+| `sort_by` | `none` | `none`, `left_to_right`, `center_to_edge`, or `area` |
+
+Multiple masks are processed serially. Each completed inpaint becomes the input
+for the next mask, and the seed is incremented by the mask index. Use
+`mask_mode=merge` to process all detections in one inpaint pass.
+
+The detector uses the `detector` backend module. For example, keep detection on
+the CPU while diffusion runs on CUDA:
+
+```bash
+--backend "diffusion=cuda0,detector=cpu"
+```

+# AnimateDiff (SD 1.5)
+
+AnimateDiff adds motion to a frozen Stable Diffusion 1.5 checkpoint by
+injecting a temporal-attention module at 20 UNet slots. The base SD 1.5
+model, VAE, and text encoder are unchanged; only the motion module produces
+the temporal residual that turns a batch of independent frames into a
+coherent animation. Reference: Guo et al., "AnimateDiff: Animate Your
+Personalized Text-to-Image Diffusion Models without Specific Tuning"
+(https://arxiv.org/abs/2307.04725).

+
+## Motion module versions
+
+Per [animatediff.net/models](https://animatediff.net/models):
+
+| Module              | Base | Native res | Character |
+|---------------------|------|------------|-----------|
+| `mm_sd_v14.ckpt`    | 1.5  | 256x256    | earliest, more jittery |
+| `mm_sd_v15.ckpt`    | 1.5  | 256x256    | improved stability over v1.4 |
+| `mm_sd_v15_v2.ckpt` | 1.5  | 384x384    | significantly better motion dynamics |
+| `v3_sd15_mm.ckpt`   | 1.5  | 512x512    | smoothest, highest quality; pairs with a Domain Adapter LoRA |
+| `mm_sdxl_v10_beta`  | SDXL | 512x512    | experimental, not yet supported here |
+
+Match your `-H -W` to the module's native resolution for best results. v3 is
+trained at 512x512 - going smaller (e.g. 384x384) still works but the motion
+character is closer to v2.
+
+## Examples
+
+Generate an 8-frame animation at 512x512, seed 42, 20 steps. The sampler /
+scheduler / CFG values below match what mm_sd15_v3 was trained with; using
+SD 1.5 defaults (euler_a, low CFG) produces noise-like output.
+
+```

+    -H 512 -W 512 --video-frames 8 --fps 8 --steps 20 -s 42 \
+    -o out.avi
+```
+
+Generate at the motion module's native 16-frame context (recommended for
+best temporal quality). Needs more VRAM at 512x512, so drop to 384x384 or
+use layer streaming:
+
+```

+    -H 384 -W 384 --video-frames 16 --fps 8 --steps 20 -s 42 \
+    -o out.avi
+```
+
+Low-VRAM streaming (verified with a 2 GiB cap on RTX 3060):
+
+```
+.\bin\Release\sd-cli.exe -M vid_gen \
+    --model ..\models\checkpoints\realisticVisionV60B1.safetensors \

+    -o out.avi
+```

+Motion is strong for scenes with motion cues in the prompt (storm/waves/wind)
+and subtle for static subjects (close-up macro), matching reference behavior.
+v2 has an additional motion module at the UNet middle block that v3 dropped;
+this impl auto-detects the topology from the checkpoint.
+
+### v3 + Domain Adapter LoRA
+
+Attaching the `v3_sd15_adapter` LoRA sharpens the base UNet output toward
+the training distribution the motion module was fine-tuned against. Same
+prompt, seed, config as above:

+
+Individual fur strands, glowing inner-ear, and richer forest detail become
+visible compared to the no-LoRA rendering.
+
+```
+sd-cli -M vid_gen --model realisticVisionV60B1.safetensors \

+       -p "close up photo of a rabbit ...<lora:v3_sd15_adapter:1.0>" ...
+```
+
+## img2video
+
+Pass a pre-rendered image via `-i / --init-img` to animate FROM it. All N output frames start from the encoded init latent, then per-frame noise is added at `--strength`. Character identity, composition, and quality are anchored by the init image; the motion module adds subtle motion on top.
+
+Left: init image rendered with `-M img_gen`. Right: 8-frame vid_gen output.
+
+<img src="../assets/animatediff/img2video_demo.gif" width="512"/>
+
+```
+sd-cli -M img_gen ... -o init.png                  # any high-quality still
+sd-cli -M vid_gen --motion-module mm_sd15_v3.safetensors \

+    -H 512 -W 512 --video-frames 8 --steps 25 -s 42 \
+    -p "..." -o out.avi
+```
+
+`--strength` controls how far the motion module is allowed to deviate from the init image (higher = more motion, lower = more static).
+
+## Notes
+
+- The motion module was trained at `video_length=16`. Running with
+  `--video-frames 16` gives the best coherence; F=8 works but shows a shorter
+  motion arc. Frame counts up to 32 are supported by the positional encoding
+  but exceed the trained regime and produce more static output.
+- At `--video-frames 1` the motion module is skipped entirely and the output
+  is bit-identical to `-M img_gen`. This avoids the single-token
+  temporal-attention degeneracy that would otherwise emit an untrained-magnitude
+  residual on a single-frame sample.
+- The base UNet is frozen, so character identity and style follow the SD 1.5
+  checkpoint you pass to `--model`. LoRAs and prompt weighting attach to the
+  base model in the usual way.
+- No mid_block motion module in v3. `mm_sdxl_v10_beta` (SDXL variant) is not
+  supported yet.
+- Output is written as MJPEG AVI. Use `--fps` to set playback speed.

+# Backend selection
+
+`stable-diffusion.cpp` has two backend assignments:
+
+- `--backend` selects the runtime backend used to execute model graphs.
+- `--params-backend` selects where model parameters are kept.
+
+If `--params-backend` is not set, auto-fit chooses parameter placement. With
+`--auto-fit off`, parameters use the same backend as their module runtime backend.
+
+## Syntax
+
+A backend assignment can be a single backend name:
+
+```shell
+sd-cli -m model.safetensors -p "a cat" --backend cpu
+```
+
+This applies to every module that does not have a more specific assignment.
+
+Assignments can also target individual modules:
+
+```shell
+sd-cli -m model.safetensors -p "a cat" --backend te=cpu,vae=cuda0,diffusion=vulkan0
+```
+
+The same syntax is used for parameter placement:
+
+```shell
+sd-cli -m model.safetensors -p "a cat" --backend cuda0 --params-backend te=cpu,vae=cpu
+```
+
+`--params-backend` also accepts the special value `disk`:
+
+```shell
+sd-cli -m model.safetensors -p "a cat" --backend cuda0 --params-backend disk
+```
+
+`--max-vram` can target resolved backend/device names:
+
+```shell
+sd-cli -m model.safetensors -p "a cat" --backend diffusion=cuda0,vae=vulkan0 --max-vram cuda0=6,vulkan0=2
+```
+
+The value is a shared per-device budget for managed weights and registered
+runner compute/cache buffers. Live free memory can lower the effective limit
+for each graph run. Driver contexts and allocations made outside the managed
+model runners are not part of this accounting, so it is not a hard physical
+VRAM cap.
+
+Module names are case-insensitive. Hyphens and underscores in module names are ignored, so `clip_vision`, `clip-vision`, and `clipvision` are equivalent.
+
+`all=`, `default=`, and `*=` can be used to set the default backend inside a mixed assignment:
+
+```shell
+sd-cli -m model.safetensors -p "a cat" --backend all=cuda0,te=cpu
+```
+
+## Multiple devices per module (layer split)
+
+A `--backend` module assignment can list several devices separated by `&`:
+
+```shell
+sd-cli -m model.safetensors -p "a cat" --backend "diffusion=cuda0&cuda1"
+```
+
+The module's transformer blocks are then distributed across the listed devices
+in contiguous ranges sized proportionally to each device's free memory (minus a
+compute-buffer headroom of about 2 GiB per device), and the
+module's graphs are executed with a `ggml_backend_sched` that runs each block
+on the device holding its weights, copying the residual stream at the range
+boundaries. The first device in the list is the module's main device: it also
+holds the non-block tensors (embeddings, final norms, small sub-runners such as
+CLIP models or projectors) and the graph inputs/outputs.
+
+Layer split is supported for the `diffusion` and `te` modules. For `te` it
+applies to the dominant text encoder (`t5xxl` or the LLM); other modules accept
+only a single device. If the module has no recognizable transformer blocks, the
+assignment falls back to the first listed device.
+
+`--params-backend` accepts no device lists. If the module has no explicit
+params assignment, each block range's parameters are loaded directly to (and,
+with `--params-backend diffusion=disk`, released directly from) its own device;
+an explicit assignment such as `te=cpu` keeps the parameters on that backend
+and stages each range to its device on demand.
+
+Layer split uses the fixed graph-cut plan to assign blocks across devices, but
+single-device segmented execution and next-segment prefetch are disabled for
+the split module. `--max-vram` can still provide the per-device limits used by
+layer split and auto-fit.
+
+Use `--list-devices` to see the device names available on the system.
+
+### Row split (`--split-mode row`)
+
+`--split-mode` selects how a multi-device module distributes its weights:
+`layer` (the default, described above) or `row`. It accepts a single mode or
+per-module assignments:
+
+```shell
+sd-cli -m model.safetensors -p "a cat" --backend "diffusion=cuda0&cuda1" --split-mode row
+sd-cli -m model.safetensors -p "a cat" --backend "diffusion=cuda0&cuda1,te=cuda0&cuda1" --split-mode diffusion=row,te=layer
+```
+
+In row mode the module keeps executing on its main (first listed) device, but
+its transformer-block matmul weights are allocated in the backend's row-split
+buffer type, which slices each weight's rows across the listed devices in
+proportion to free memory and runs those matmuls on all devices in parallel.
+Compared to a layer split this uses all GPUs within every layer (instead of
+sequentially device by device) at the cost of a cross-device reduction per
+matmul - usually the faster option when the devices have fast interconnect.
+
+Row split requires a compatible split-buffer export from the linked GGML
+backend. If it is unavailable (or the listed devices belong to different backend
+registries), the module falls back to a layer split.
+Embeddings, normalization weights, biases and other non-block tensors stay in
+regular buffers on the main device.
+
+Row-split execution can use graph segments, but split weights are loaded
+synchronously instead of using the normal single-device prefetch path. Because
+GGML does not expose exact shard allocation sizes, the managed budget currently
+counts a split buffer's full size on each participating device. This is a
+conservative bound and can reject otherwise feasible layouts.
+
+Direct ("immediately") LoRA application cannot patch row-split tensors; with
+`--split-mode row` the automatic LoRA mode selects runtime application, and an
+explicit `--lora-apply-mode immediately` skips the split tensors with a
+warning.
+
+## Automatic placement (`--auto-fit on|off`)
+
+`--auto-fit` requires `on` or `off` and defaults to `on` when omitted.
+Explicit `--params-backend` assignments disable auto-fit,
+regardless of argument order, even with `--auto-fit on`.
+
+Auto-fit preserves explicit `--backend` assignments, including per-module
+assignments and device lists. For modules without a runtime assignment, it chooses
+the GPU with the largest available memory budget (the first device on a tie).
+It then derives parameter placements from the model metadata, each module's
+compute devices, and the remaining memory budgets. The chosen backend
+specifications are printed.
+
+```shell
+sd-cli -m model.safetensors -p "a cat" --auto-fit on
+sd-cli -m model.safetensors -p "a cat" --auto-fit on --max-vram cuda0=8,cuda1=14
+sd-cli -m model.safetensors -p "a cat" --backend cuda0
+sd-cli -m model.safetensors -p "a cat" --backend diffusion=cuda0,te=cpu,vae=cuda1
+sd-cli -m model.safetensors -p "a cat" --auto-fit off
+```
+
+Budgets reuse `--max-vram`: a positive per-device value caps what auto-fit
+plans with on that device, a negative value means "free memory minus that many
+GiB", and with no budget set each device's free memory minus a 512 MiB margin
+is used. These resolved GPU budgets, including the safety margin, also drive
+the runner's graph-cut capacity checks.
+
+Runtime capacity checks also leave 512 MiB of currently free device memory for
+backend scratch buffers and pipelines, including with explicit backend assignments.
+They cap free-memory reports by the device's total memory minus tracked
+resident allocations. Vulkan reports exceeding total memory are rejected because
+its heap-budget subtraction can underflow. Other backends use the cap instead of
+treating such reports as zero free memory. Failed checks log the reported free and
+total memory alongside tracked weight and runtime allocations.
+With `--mmap`, device-backed mappings count toward these budgets at their full
+mapped-file size, once per device buffer even when multiple parameter blocks
+share it. Mappings retained in the loader cache continue to count.
+
+Components are considered in `diffusion`, `te`, `vae` order so that repeatedly
+used diffusion weights have priority. Each component's weights use the first
+storage location with enough remaining budget:
+
+1. The component's compute GPU, leaving estimated space for computation and weight staging.
+2. CPU RAM, reserving the larger of 2 GiB or 10% of available RAM for other work.
+3. Another GPU, choosing the one with the largest remaining budget that fits.
+4. Disk, reloading weights on demand.
+
+GPU cache space follows the same component priority. Before a lower-priority
+component can become permanently resident, the planner leaves room for the full
+weights and estimated compute space of higher-priority offloaded components.
+If offloaded diffusion already needs the entire main GPU budget, TE and VAE also
+use offloaded parameters. Their GPU copies can then be released after their
+phases, leaving more room to reuse diffusion weights across sampling steps.
+CPU parameter residency allows GPU weight caching; it does not force every
+weight to be copied again at every step.
+
+RAM and GPU budgets are shared across components. Each component uses a single
+parameter backend; several other GPUs' capacities are not combined to store
+one component. If available RAM cannot be queried, RAM residency is skipped.
+Weights stored on another GPU are copied to the component's compute devices for
+execution. CPU modules use RAM or disk. Compute reserves and cache priority are
+accounted for separately on each device, so a CPU module does not reserve GPU
+space. Storage on another module's GPU also leaves room for that module's work.
+
+Auto-fit does not select multi-GPU layer/row computation itself. Explicit device
+lists and `--split-mode` still control that computation. Before the runners have
+built their split plans, auto-fit conservatively counts the full component size
+on each listed GPU when checking residency and cache space. This can offload
+parameters even when a split layout would fit; use `--auto-fit off` to keep the
+default split-device parameter placement.
+
+For example, a diffusion model whose full weights exceed the main GPU's budget
+can use `--backend diffusion=cuda0 --params-backend diffusion=cpu` when RAM is
+sufficient. Automatic graph segmentation can then load the required weights
+for each segment and reclaim idle GPU copies. `--disable-segmented-compute`
+still disables segmentation.
+
+Initial compute reserves are estimates (2 GiB for diffusion and text encoders,
+1 GiB for VAE); higher-priority placements also leave staging space for the
+largest weight tensor of each lower-priority offloaded component. Actual segment
+weights, compute buffers and caches must
+still fit the runner's capacity checks. Offloading weights does not guarantee
+that every resolution or frame count will fit, and auto-fit does not change a
+component to CPU computation solely because its full weights exceed VRAM.
+If a VAE decode fails, decoding retries with spatial tiling even when `--auto-fit`
+is off; supported video decoders try temporal tiling first and can then add
+spatial tiling. Spatial retries use half-size tiles along each latent dimension.
+
+## Modules
+
+| Module | Purpose | Accepted names |
+| --- | --- | --- |
+| `diffusion` | UNet, DiT, MMDiT, Flux, Wan, Qwen Image, and other diffusion models | `diffusion`, `model`, `unet`, `dit` |
+| `te` | Text encoders and conditioners | `te`, `clip`, `text`, `textencoder`, `textencoders`, `conditioner`, `cond`, `llm`, `t5`, `t5xxl` |
+| `clip_vision` | CLIP vision encoder | `clip_vision`, `clipvision`, `clip-vision`, `vision` |
+| `vae` | VAE and TAE | `vae`, `firststage`, `autoencoder`, `tae` |
+| `controlnet` | ControlNet | `controlnet`, `control` |
+| `photomaker` | PhotoMaker ID encoder and PhotoMaker LoRA | `photomaker`, `photomakerid`, `pmid`, `photo` |
+| `upscaler` | ESRGAN upscaler | `upscaler`, `esrgan`, `hires` |
+| `detector` | ADetailer YOLOv8 detector | `detector`, `adetailer`, `yolo` |
+
+`te` is the preferred module name for text encoders. `clip` is kept as an accepted alias because many existing commands and model names use CLIP terminology.
+
+## Backend names
+
+Backend names are resolved against the GGML backend device list. Matching is case-insensitive and accepts exact names or unique prefixes, so common values include names such as:
+
+- `cpu`
+- `cuda0`
+- `vulkan0`
+- `metal`
+
+The special values `auto`, `default`, and an empty backend name select the default backend. The default preference is GPU, then integrated GPU, then CPU.
+
+The special value `gpu` selects the first GPU backend, falling back to the first integrated GPU backend.
+
+The special value `disk` is accepted only by `--params-backend`. `--backend disk` is invalid because `disk` is a parameter residency mode, not a runtime compute backend.
+
+## Runtime backend vs. parameter backend
+
+The runtime backend controls where graph execution runs. The parameter backend controls where model weights are allocated or whether they are reloaded from disk on demand.
+
+For example:
+
+```shell
+sd-cli -m model.safetensors -p "a cat" --backend cuda0 --params-backend cpu
+```
+
+This runs all modules on `cuda0`, but stores parameters in CPU RAM. During execution, parameters are moved to the runtime backend as needed.
+
+For example:
+
+```shell
+sd-cli -m model.safetensors -p "a cat" --backend cuda0 --params-backend disk
+```
+
+This runs all modules on `cuda0`, reloads parameters from the model file as needed, and releases those parameter buffers after use.
+
+Outside `--auto-fit`, `disk` is never selected implicitly. If `--params-backend` is not set, parameters use the runtime backend.
+
+Per-module assignments can be mixed:
+
+```shell
+sd-cli -m model.safetensors -p "a cat" --backend diffusion=cuda0,te=cpu,vae=cpu --params-backend diffusion=cuda0,te=cpu,vae=cpu
+```
+
+This keeps text encoding and VAE execution on CPU while the diffusion model runs on GPU.
+
+## Backend sharing and lifetime
+
+Backends are managed by `SDBackendManager`.
+
+Within one manager, backend instances are cached by resolved backend device name. If multiple modules request the same backend, they share the same `ggml_backend_t`.
+
+For example:
+
+```shell
+--backend te=cpu,vae=cpu
+```
+
+uses one shared CPU backend for both `te` and `vae` runtime execution.
+
+Runtime and parameter assignments also share the same backend cache. If `--backend diffusion=cuda0` and `--params-backend diffusion=cuda0` resolve to the same device, both use the same backend instance.
+
+`--params-backend disk` does not create a separate backend instance. Parameters are loaded lazily using the module runtime backend.
+
+`SDBackendManager` owns the backend instances and frees them when the context or upscaler is destroyed. Model runners receive non-owning runtime and parameter backend pointers and do not free them.
+
+## Compatibility flags
+
+The example CLI/server still accepts these older CPU placement flags as compatibility aliases:
+
+- `--clip-on-cpu`
+- `--vae-on-cpu`
+- `--control-net-cpu`
+- `--offload-to-cpu`
+
+`--clip-on-cpu`, `--vae-on-cpu`, and `--control-net-cpu` are deprecated. The example argument layer prepends `te=cpu`, `vae=cpu`, and `controlnet=cpu` to `--backend` before creating the context.
+
+`--offload-to-cpu` prepends a CPU default to the parameter assignment in the caller before creating the context:
+
+```shell
+--params-backend '*=cpu'
+```
+
+Because this default is inserted first, later explicit `--params-backend` entries can still override it, for example `--offload-to-cpu --params-backend te=disk` keeps non-TE parameters on CPU and reloads TE parameters from disk.
+
+Library callers should set `backend` and `params_backend` directly. `sd_ctx_params_init()`
+enables `auto_fit` by default; a nonempty `params_backend` assignment disables it.
+The `backend` assignment constrains auto-fit's compute placement.

+## Selecting a GGML source tree
+
+By default, sd.cpp builds the patched GGML submodule in `ggml/`. To build with
+an upstream GGML checkout instead, enable `SD_USE_UPSTREAM_GGML` and set
+`SD_GGML_SOURCE_DIR`:
+
+```shell
+cmake -S . -B build-upstream -DSD_USE_UPSTREAM_GGML=ON -DSD_GGML_SOURCE_DIR=../ggml-upstream
+cmake --build build-upstream --config Release
+```
+
+The selected source tree supplies both the library and its private headers.
+Backend options such as `-DSD_CUDA=ON` apply to the selected tree as usual.
+
+`SD_USE_UPSTREAM_GGML` defaults to `OFF`, which enables the patched GGML
+extensions. Set it to `ON` when using upstream GGML; it selects the compatibility
+mode and does not download or replace the GGML source tree. Upstream mode keeps
+the original FP8 safetensors handling: FP8 tensors are converted to F16 at load
+time (one byte per element in the file, two in RAM and VRAM). INT8
+tensorwise/convrot is disabled and its model files are rejected with an explicit
+error. FP8 GGUF files, FP8 weight type requests and tensor type rules are also
+rejected; no automatic conversion is performed.
+
+Upstream GGML may lack some operators and performance optimizations provided by
+the patched version. A warning is emitted during CMake configuration and when
+creating an inference context. Ordinary floating-point and shared GGML
+quantization types remain available, subject to backend operator support.
+
+`SD_USE_SYSTEM_GGML=ON` instead links an installed GGML CMake package, located
+with `ggml_DIR` or `CMAKE_PREFIX_PATH`. In that mode, `SD_GGML_SOURCE_DIR` must
+point to the matching source tree for private headers. The installed library
+must use the same ABI settings as sd.cpp, including `GGML_MAX_NAME`.
+Set `SD_USE_UPSTREAM_GGML=ON` as well if the installed package is upstream GGML.
+
+## WebP and WebM Support in Examples
+
+The example applications (`examples/cli` and `examples/server`) use `libwebp` to support WebP image I/O, and `examples/cli` can also use `libwebm` for `.webm` video output. Both are enabled by default. WebM output currently reuses `libwebp` to encode each frame as VP8 before muxing with `libwebm`.
+
+If you do not want WebP/WebM support, you can disable them at configure time:
+
+```shell
+mkdir build && cd build
+cmake .. -DSD_WEBP=OFF -DSD_WEBM=OFF
+cmake --build . --config Release

+## Caching
+
+Caching methods accelerate diffusion inference by reusing intermediate computations when changes between steps are small.
+
+### Conditioning Cache
+
+Conditioning results are cached per model context using an LRU cache. The default
+capacity is **0 (disabled) for `sd-cli`** and **4 entries for `sd-server` and the C
+API**. Set `--conditioning-cache-size N` to change the limit; `0` disables caching.
+For example, `sd-cli -m model.safetensors -p "a cat" --conditioning-cache-size 4`
+enables the cache in the CLI. The C API option is
+`sd_ctx_params_t::conditioning_cache_size`, initialized by `sd_ctx_params_init()`.
+This cache is independent of the diffusion-step `--cache-mode` options below.
+
+### Cache Modes
+
+| Mode | Target | Description |
+|------|--------|-------------|
+| `ucache` | UNET models | Condition-level caching with error tracking |
+| `easycache` | DiT models | Condition-level cache |
+| `dbcache` | DiT models | Block-level L1 residual threshold |
+| `taylorseer` | DiT models | Taylor series approximation |
+| `cache-dit` | DiT models | Combined DBCache + TaylorSeer |
+| `spectrum` | UNET and DiT models | Chebyshev + Taylor output forecasting |
+
+### UCache (UNET Models)
+
+UCache caches the residual difference (output - input) and reuses it when input changes are below threshold.
+
+```bash
+sd-cli -m model.safetensors -p "a cat" --cache-mode ucache --cache-option "threshold=1.5"
+```
+
+#### Parameters
+
+| Parameter | Description | Default |
+|-----------|-------------|---------|
+| `threshold` | Error threshold for reuse decision | 1.0 |
+| `start` | Start caching at this percent of steps | 0.15 |
+| `end` | Stop caching at this percent of steps | 0.95 |
+| `decay` | Error decay rate (0-1) | 1.0 |
+| `relative` | Scale threshold by output norm (0/1) | 1 |
+| `reset` | Reset error after computing (0/1) | 1 |
+
+#### Reset Parameter
+
+The `reset` parameter controls error accumulation behavior:
+
+- `reset=1` (default): Resets accumulated error after each computed step. More aggressive caching, works well with most samplers.
+- `reset=0`: Keeps error accumulated. More conservative, recommended for `euler_a` sampler.
+
+### EasyCache (DiT Models)
+
+Condition-level caching for DiT models. Caches and reuses outputs when input changes are below threshold.
+
+```bash
+--cache-mode easycache --cache-option "threshold=0.3"
+```
+
+#### Parameters
+
+| Parameter | Description | Default |
+|-----------|-------------|---------|
+| `threshold` | Input change threshold for reuse | 0.2 |
+| `start` | Start caching at this percent of steps | 0.15 |
+| `end` | Stop caching at this percent of steps | 0.95 |
+
+### Cache-DIT (DiT Models)
+
+For DiT models like FLUX and QWEN, use block-level caching modes.
+
+#### DBCache
+
+Caches blocks based on L1 residual difference threshold:
+
+```bash
+--cache-mode dbcache --cache-option "threshold=0.25,warmup=4"
+```
+
+#### TaylorSeer
+
+Uses Taylor series approximation to predict block outputs:
+
+```bash
+--cache-mode taylorseer
+```
+
+#### Cache-DIT (Combined)
+
+Combines DBCache and TaylorSeer:
+
+```bash
+--cache-mode cache-dit
+```
+
+#### Parameters
+
+| Parameter | Description | Default |
+|-----------|-------------|---------|
+| `Fn` | Front blocks to always compute | 8 |
+| `Bn` | Back blocks to always compute | 0 |
+| `threshold` | L1 residual difference threshold | 0.08 |
+| `warmup` | Steps before caching starts | 8 |
+
+#### SCM Options
+
+Steps Computation Mask controls which steps can be cached:
+
+```bash
+--scm-mask "1,1,1,1,0,0,1,0,0,0,1,0,0,0,1,0,0,0,1,1"
+```
+
+Mask values: `1` = compute, `0` = can cache.
+
+| Policy | Description |
+|--------|-------------|
+| `dynamic` | Check threshold before caching |
+| `static` | Always cache on cacheable steps |
+
+```bash
+--scm-policy dynamic
+```
+
+### Spectrum (UNET and DiT Models)
+
+Spectrum uses Chebyshev polynomial fitting blended with Taylor extrapolation to predict denoised outputs, skipping entire forward passes. Based on the paper [Spectrum: Adaptive Spectral Feature Forecasting for Efficient Diffusion Sampling](https://github.com/tingyu215/Spectrum).
+
+```bash
+sd-cli -m model.safetensors -p "a cat" --cache-mode spectrum
+```
+
+#### Parameters
+
+| Parameter | Description | Default |
+|-----------|-------------|---------|
+| `w` | Chebyshev vs Taylor blend weight (0=Taylor, 1=Chebyshev) | 0.40 |
+| `m` | Chebyshev polynomial degree | 3 |
+| `lam` | Ridge regression regularization | 1.0 |
+| `window` | Initial window size (compute every N steps) | 2 |
+| `flex` | Window growth per computed step after warmup | 0.50 |
+| `warmup` | Steps to always compute before caching starts | 4 |
+| `stop` | Stop caching at this fraction of total steps | 0.9 |
+
+### Performance Tips
+
+- Start with default thresholds and adjust based on output quality
+- Lower threshold = better quality, less speedup
+- Higher threshold = more speedup, potential quality loss
+- More steps generally means more caching opportunities

+# Image Editing
+
+Image editing in `stable-diffusion.cpp` allows you to use reference images to guide the generation process, enabling tasks like identity preservation, style transfer, or layout modification.
+
+
+## Supported Models
+
+Depending on the architecture, different models handle reference images differently.
+
+| Model | Default Preset |
+| :--- | :--- |
+| [**FLUX.1-Kontext-dev**](./kontext.md) | `flux_kontext` |
+| [**LongCat Image Edit**](./longcat_image.md) | `longcat` |
+| [**Qwen Image Edit**](./qwen_image_edit.md) | `qwen` |
+| **Qwen Image LAYERED** | `qwen_layered` |
+| [**Flux.2 [Dev] / Flux.2 [Klein]**](./flux2.md) | `flux2` |
+| [**Boogu Image Edit**](./boogu_image.md) | `z_image_omni` |

+| [**LLaDA-Image**](./llada_image.md#image-editing) | `llada_image` |
+| **Anima (Community Edit LoRAs)** | `cosmos_reference` |
+
+Stable-diffusion.spp also supports basic Unet-based editing models like instruct-pix2pix or CosXL-Edit. This document is not about those.
+
+---
+
+## Configuring Reference Modes (`--ref-image-args`)
+
+For a one-time input transform before reference presets and model processing,
+including cropping, padding, and resizing algorithms, see [Image preprocessing](./image_preprocessing.md).
+
+Different DiT-based editing models require different configurations to process reference images correctly (e.g., whether to use a Vision Language Model (VLM) encoder or pass VAE-encoded images directly to the DiT).
+
+To simplify this, we provide **Presets**. By default, the system automatically selects the best preset based on the model architecture. However, you can override this using the `--ref-image-args` argument.
+
+### Usage
+The `--ref-image-args` argument accepts a comma-separated list of key-value pairs:
+
+**Using a preset:**
+`--ref-image-args "preset=qwen_layered"`
+
+**Using a preset with a specific override:**
+`--ref-image-args "preset=krea2_edit,force_ref_timestep_zero=true"`
+
+### Available Presets
+
+| Preset | Primary Use Case |
+| :--- | :--- |
+| `flux_kontext` | FLUX.1 Kontext |
+| `longcat` | LongCat Image Edit |
+| `flux2` | FLUX.2 models |
+| `qwen` | Qwen Image Edit |
+| `qwen_layered` | Qwen Image Layered |
+| `z_image_omni` | Boogu, Z-Image Omni |
+| `krea2_ostris_edit` | Most Krea2 Community edit LoRAs (trained with Ostris script) |
+| `mage_flow` | Mage-Flow-Edit |
+| `krea2_edit` | Specifically for [lbouaraba/krea2edit](https://huggingface.co/conradlocke/krea2-identity-edit). (or similar) |
+| `cosmos_reference` | For Anima |
+| `default` | Uses the automatic detection based on model architecture. |
+
+---
+
+## Advanced Parameter Reference
+
+If presets are insufficient, you can manually configure the following parameters via `--ref-image-args`:
+
+| Key | Type | Description | Allowed Values |
+| :--- | :--- | :--- | :--- |
+| `preset` | string | Overrides the automatic preset. | (See the Presets table above) |
+| `pass_to_vlm` | bool | Whether reference images are passed to the VLM encoder. | `true`, `false` |
+| `pass_to_dit` | bool | Whether VAE-encoded references are passed directly to the DiT. | `true`, `false` |
+| `ref_index_mode` | string | Behavior of the RoPE index. | `fixed`, `increase`, `decrease` |
+| `force_ref_timestep_zero` | bool | Forces timestep=0 for reference tokens. | `true`, `false` (Krea2 only) |
+| `resize_before_vae` | bool | Whether reference images are resized before VAE encoding. | `true`, `false` |
+| `vae_input_max_pixels` | int | Maximum pixel area for VAE reference inputs. | Integer |
+| `vlm_resize_mode` | string | How to resize VLM reference inputs. | `longest_side`, `area`, `none` |
+| `vlm_max_size` | int | Maximum VLM input size; interpreted according to `vlm_resize_mode`. | Integer |
+| `vlm_min_size` | int | Minimum VLM input size; interpreted according to `vlm_resize_mode`. | Integer |
+| `vlm_size` | int | Shortcut to set both VLM min and max size to the same value. | Integer |
+
+### Preset Default Values
+
+For a technical overview of how each preset is configured, see the table below.
+
+| Preset | VLM | RoPE Index | Cond Resize | Special Notes |

+## Use original FP8 weights
+
+The original Ideogram4 FP8 safetensors can be loaded directly. FP8 tensors stay
+at one byte per element in RAM and VRAM. Backends that cannot multiply FP8
+weights directly cast only the active layer to a temporary BF16 tensor during
+execution; the loader does not expand the entire checkpoint to BF16.
+
+With `SD_USE_UPSTREAM_GGML=ON`, FP8 tensors are converted to F16 at load time
+instead (two bytes per element in RAM and VRAM).
+
+Use `ideogram4_fp8.safetensors` and `ideogram4_uncond_fp8.safetensors` directly
+with `--diffusion-model` and `--uncond-diffusion-model`, respectively.
+
+## Optional conversion for quantization
+
+The following conversion is only needed when creating a quantized GGUF model.
+
+fp8 scale -> bf16
+
+```
+python .\convert_fp8_scale_to_bf16.py --input .\ideogram4_fp8.safetensors --output ideogram4_bf16.safetensors
+python .\convert_fp8_scale_to_bf16.py --input .\ideogram4_uncond_fp8.safetensors --output ideogram4_uncond_bf16.safetensors
+```
+
+bf16 -> q8
+
+```
+.\bin\Release\sd-cli.exe -M convert -m ideogram4_bf16.safetensors -o ideogram4-Q8_0.gguf --tensor-type-rules "^layers.*adaln_modulation.*weight=q8_0,layers.*attention.o.*weight=q8_0,layers.*attention.qkv.*weight=q8_0,layers.*feed_forward.*weight=q8_0" -v

+```

+If you want lower VRAM usage, you can change the quantization from q8_0 to a lower-level quantization, such as q4_0.

+  -> one input transform
+  -> original generation pipeline and model-specific processing
+```
+
+These rules do not override internal VAE, CLIP/VLM, ControlNet, or pixel-patch preprocessing.
+`--ref-image-args` retains its existing meaning and runs after this input transform.
+
+## Inputs and defaults
+
+| `target` | Input | Default geometry | Indexed? |
+| --- | --- | --- | --- |
+| `init` | img2img image or video first frame | Center crop to the generation aspect ratio, then resize | No |
+| `end` | Video last frame | Center crop, then resize | No |
+| `mask` | Inpainting mask | Inherit init geometry; otherwise center crop, then resize | No |
+| `control` | Control image | Center crop, then resize | No |
+| `ref` | Reference images | Preserve source dimensions | Yes |
+| `ip-adapter` | IP-Adapter image | Preserve source dimensions | No |
+| `id` | PhotoMaker identity images | Preserve source dimensions | Yes |
+| `control-frame` | Control video frames | Center crop, then resize | Yes |
+
+Canvas defaults use the aligned generation dimensions. Reference, IP-Adapter,
+and identity inputs use their original dimensions unless overridden. Default
+resampling is nearest for images and nearest-exact for masks.
+
+These defaults are shared by CLI, server, and C API. Moving geometry out of
+the loaders replaces the previous CLI/server BOX/sRGB resizing, so default
+pixels are not guaranteed to match earlier builds.
+
+Reference video and audio preprocessing are outside these image rules.
+Preprocessing options apply to `img_gen` and `vid_gen`, not standalone upscale
+or ADetailer mode. ADetailer clears the user's rules for its internal crops.
+
+## Rules
+
+Rules are comma-separated `key=value` lists. Repeat the CLI option or separate
+rules with semicolons. Every rule requires a `target` and at least one option.
+Rule syntax and input compatibility are checked when image/video generation
+starts. Unknown keys, invalid values, duplicate keys in a rule, missing images,
+and out-of-range indices cause generation to fail with an error log.
+
+Omit `index` to configure every image of that type; otherwise use a zero-based
+index. CLI directory inputs follow filename order. Indexed rules override
+type-wide rules field by field, regardless of order. At equal specificity,
+the last value for a field wins. `auto` selects the input preset.
+
+| `mode` | Input transform |
+| --- | --- |
+| `auto` | Use the input's default geometry |
+| `none` | Keep source dimensions without resizing, cropping, or padding |
+| `stretch` | Resize to the target dimensions |
+| `crop` | Crop a target-sized rectangle without resizing; fail if the source is too small |
+| `crop-resize` | Crop to the target aspect ratio, then resize |
+| `fit-pad` | Fit the entire image inside the target dimensions, preserving aspect ratio, then pad |
+
+`width` and `height` must be specified together as positive integers. They
+override the input transform's dimensions, not the generation or encoder size.
+For a native-size preset, specifying dimensions without a mode selects stretch.
+`mode=none` with explicit dimensions different from the source is contradictory
+and is rejected.
+
+`anchor=center|top|bottom|left|right` selects crop/padding placement.
+`pad_color=#RRGGBB` or `#RRGGBBAA` selects padding, defaulting to opaque black.
+A grayscale mask uses the first color component.
+
+`filter=auto|nearest|nearest-exact|bilinear|bicubic|lanczos` selects resampling.
+`antialias=auto|true|false` enables antialiasing automatically for filtered
+downscaling; explicit true requires bilinear, bicubic, or Lanczos.
+Filtered RGBA resizing uses premultiplied alpha.
+
+`canny=true|false` enables edge detection for any supported image target,
+defaulting to `false`. It runs once after geometry, before the original
+generation pipeline, including with `mode=none`. Grayscale, grayscale-alpha,
+RGB, and RGBA inputs are supported; alpha is preserved.
+
+Each input has its own Canny setting. Indexed rules can enable or disable it
+for individual references, identity images, or video control frames.
+
+```sh
+--image-preprocess "target=init,mode=fit-pad,canny=true"
+--image-preprocess "target=ref,index=0,mode=none,canny=true"
+--image-preprocess "target=control-frame,index=2,canny=true"
+```
+
+Init and mask sources must have the same dimensions. The mask inherits the
+init crop, resize, and padding coordinates, while retaining its own filter,
+padding value, and Canny setting. Conflicting mask geometry is rejected. An
+omitted mask remains absent until the original pipeline creates its default mask.
+
+## Downstream behavior
+
+`mode=none` only skips the input geometry transform. For example:
+
+```sh
+--image-preprocess "target=init,mode=none" \
+--image-preprocess "target=ref,mode=none"
+```
+
+The init image is still adapted to the generation canvas by the original
+pipeline. Reference images still follow `--ref-image-args` and model-specific
+resizing. CLIP retains its fixed input dimensions and normalization. HiDream-O1
+retains its original pixel-reference and visual preprocessing.
+
+Existing sharing between consumers is preserved: for example, Wan img2video
+uses the same adapted first frame for VAE conditioning and CLIP. High-resolution
+passes reuse the prepared images and apply their original size adaptation;
+they do not apply the user's crop a second time.
+
+To disable reference resizing before VAE encoding, use
+`--ref-image-args "resize_before_vae=false"` or the server field
+`"ref_image_args": "resize_before_vae=false"`. This is separate from
+`target=ref,mode=none`, which only skips input geometry. Model constraints
+still apply.
+
+## Server requests
+
+Native image/video requests and SDAPI accept `image_preprocess` as a string or
+an array of rule strings:
+
+```json
+{
+  "image_preprocess": [
+    "target=init,mode=fit-pad,filter=bicubic",
+    "target=mask,filter=nearest-exact",
+    "target=ref,index=0,mode=none"
+  ]
+}
+```
+
+OpenAI-compatible requests accept it through
+`<sd_cpp_extra_args>{...}</sd_cpp_extra_args>` in the prompt.
+Request rules replace server-default rules. Generation metadata records the
+user rules; image encodings and channel conventions are unchanged.
+
+## C API
+
+Set `image_preprocess` on the existing image/video generation parameters.
+The `generate_image()` and `generate_video()` signatures are unchanged:
+
+```c
+sd_img_gen_params_t params;
+sd_img_gen_params_init(&params);
+/* Set prompt, original-resolution input images, and generation options. */
+params.image_preprocess.rules = "target=init,mode=crop-resize,filter=lanczos;"
+                                "target=mask,filter=nearest-exact";
+bool ok = generate_image(ctx, &params, &images, &count);
+```
+
+Both generation parameter initializers set `image_preprocess.rules` to `NULL`,
+selecting input presets. Rule strings are borrowed for the synchronous call.
+The library owns temporary transformed pixels; caller images and arrays are
+not modified. Add `canny=true` to the desired target's rule in
+`image_preprocess.rules` to enable Canny.
+
+The parameter structs have grown; applications and bindings must be rebuilt.
