Ernie4.5 VL MoE

Breaking Changes

●Issue #1

Tensor parallelism (TP) support for dense and MoE decoder-only models has been fixed and stabilized, requiring users to update their TP configurations and conversion mappings accordingly.

●Issue #2

The `Ernie4.5 VL MoE` model class and configuration names have been renamed to align with vLLM/SGLang conventions, requiring users to update any references to the old model names in their code.

Migration Steps

  1. 1
    Update TP configurations and conversion mappings due to stabilized Tensor parallelism support for dense and MoE decoder-only models.
  2. 2
    Update any references to the old `Ernie4.5 VL MoE` model class and configuration names to align with vLLM/SGLang conventions.

Release Summary

This release introduces several new models across various modalities, including EuroBERT, VibeVoice ASR, TimesFM 2.5, and multiple vision/audio models. It also includes critical fixes and stabilization for Tensor Parallelism support in decoder-only models.
