Alibaba released open weights for Qwen3.8-2.4T-A95B, also identified by NVIDIA as Qwen3.8-Max. NVIDIA described it as Alibaba’s largest open-weight model.

The model contains 2.4 trillion parameters. NVIDIA’s account characterized it as bringing near-frontier capabilities to an open-weight release.

NVIDIA documented how to serve the model on GB300 NVL72 systems. The blog’s title also identifies configurable reasoning as part of the serving configuration.

The source distinguishes the model release from the hardware used to serve it: Alibaba released the model weights, while NVIDIA provided the GB300 NVL72 deployment documentation. The supplied description does not specify a commercial customer deployment, service price, or cluster count.
