## Summary LTX-2 (`ltx-core`, `ltx-pipelines`, `ltx-trainer`) is a third-party dependency developed and provided by Lightricks. It is governed by the [LTX Community License Agreement](https://github.com/Lightricks/LTX-2/blob/main/LICENSE), **not** the Apache 2.0 license that covers NVIDIA Model Optimizer. Per legal guidance, all integration points must clearly surface this to users. - Add `[!WARNING]` license notice blocks at the top of all LTX-2-related READMEs (`examples/diffusers`, `examples/diffusers/distillation`, `examples/windows/diffusers/qad_example`) - Add `warnings.warn(UserWarning)` at every LTX package import site in Python files, covering both top-level and lazy imports: - `examples/diffusers/distillation/distillation_trainer.py` - `examples/diffusers/quantization/calibration.py` - `examples/diffusers/quantization/pipeline_manager.py` - `examples/windows/diffusers/qad_example/sample_example_qad_diffusers.py` - `modelopt/torch/export/diffusers_utils.py` - `modelopt/torch/quantization/plugins/diffusion/ltx2.py` - Add license notice comment to `requirements.txt` files that list LTX packages, so the obligation is visible at install time - Update `.github/CODEOWNERS` so all `requirements*.txt` files (covering variants like `requirements-dev.txt`) are owned by `@NVIDIA/modelopt-setup-codeowners` regardless of location, via a last-match-wins rule **Design notes:** - For library files (`diffusers_utils.py`, `ltx2.py`), the warning is placed at the lazy import site inside functions — it fires only when LTX-2 code paths are actually invoked, not at module import time, to avoid polluting non-LTX users - For example entry-point scripts that are LTX-2-only, the warning fires at module load time (after all imports, to satisfy ruff E402) ## Test plan - [ ] Confirm `pre-commit run --all-files` passes (ruff, mypy, markdownlint, bandit all clean) - [ ] Verify warning appears at runtime when running an LTX-2 quantization or distillation example - [ ] Confirm non-LTX code paths (FLUX, SDXL, SD3) do not emit the warning 🤖 Generated with [Claude Code](https://claude.com/claude-code) <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Documentation** * Added third-party license notices across documentation and requirements files clarifying LTX-2 packages are governed by the LTX Community License Agreement rather than NVIDIA Model Optimizer's Apache 2.0 license. * **Chores** * Updated code ownership configuration for requirements files. * Added runtime warnings to notify when LTX-2 dependencies are accessed. <!-- end of auto-generated comment: release notes by coderabbit.ai --> Signed-off-by: Keval Morabia <28916987+kevalmorabia97@users.noreply.github.com> Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com>
