What Happened
Alibaba published Qwen3.8-2.4T-A95B on August 12, 2026, according to the official repository’s release log. This date records the downloadable large checkpoint, rather than the earlier hosted-model announcement. A smaller 27-billion-parameter member followed separately.
Why It Matters
The release made a Qwen Max-class model available for deployment outside Alibaba’s services. It expanded the upper end of the downloadable-model ecosystem, while demonstrating the importance of distinguishing an API product from the checkpoint that underlies it.
Technical Details
The model contains 2.4 trillion parameters and activates 95 billion. Its architecture combines Gated DeltaNet, gated attention and mixture-of-experts layers. The native context is 262,144 tokens, with extension supported beyond one million. Crucially, this checkpoint is text-only and requires thinking mode; hosted Qwen3.8-Max adds features such as visual input and non-thinking operation. The weights use a custom Qwen3.8-Max license, not the repository’s Apache 2.0 code license.
