+- [04/12/2026] [**MiniMax-M2.5 / M2.7**](https://github.com/NVIDIA-NeMo/Megatron-Bridge/tree/main/examples/models/minimax_m2) are now supported! Both models share the same architecture as MiniMax-M2 and work with the existing bridge out of the box — checkpoint conversion and inference verified on real FP8 checkpoints.

 - [04/10/2026] [**Qwen3-ASR**](https://github.com/NVIDIA-NeMo/Megatron-Bridge/tree/main/examples/models/audio_lm/qwen3_asr) is now supported! Checkpoint conversion and inference for [Qwen3's ASR model](https://github.com/QwenLM/Qwen3-ASR) are available on **main**.
 
 - [04/09/2026] [**Bailing MoE V2**](https://github.com/NVIDIA-NeMo/Megatron-Bridge/tree/main/examples/models/bailing) is now supported! Checkpoint conversion and inference for the Bailing MoE V2 model are available on **main**. Thank you to [@ccclyu](https://github.com/ccclyu) for the community contribution!

 ## Hardware Requirements
 
 MiniMax-M2 requires **at least 2 nodes (16 GPUs)** for inference and conversion. The model cannot fit on a single 8-GPU node because:
