### Description MBridge main (nemo:26.08) will initialize Nemotron-H as HybridModel instead of MambaModel (subclassed of HybridModel). Also make minimum nemo container 26.04 ### Testing Tested Nemotron-3-Nano PTQ with MBridge main (fails otherwise) Tested locally `tests/gpu_megatron` and `tests/examples/megatron_bridge` with `nemo:26.06.01` + Mount latest MBridge/Mcore GH CICD tests will be added with nemo:26.08 release <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Added TE HybridModel stack-spec support and enabled Megatron-Bridge hybrid providers/models for export/import and runtime handling. * **Updates** * Dataset packing now oversamples raw text at **16x** and improves the packed-mode underflow warning. * Quantization: `--quant_cfg` now defaults to `None` unless explicitly set (or via `--recipe`). * Distillation example: validation settings are provided via a dedicated top-level validation configuration. * Improved plugin import warnings to report the originating call location; model stats now support HybridModel. * **Deprecations** * Megatron-Bridge / Megatron-LM optimization features now require NeMo container `nemo:26.04` or newer (`nemo:26.06` recommended). * The Mamba stack specification helper is deprecated. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Signed-off-by: Keval Morabia <28916987+kevalmorabia97@users.noreply.github.com>
