Qwen 3.8 2.4T A95B is the open-weight checkpoint behind the Qwen3.8-Max serving release. Its repository contains FP8-quantized weights for a hybrid Mixture-of-Experts model with 2.4 trillion total parameters and 95 billion active parameters. The architecture combines Gated DeltaNet and Gated Attention.

The weights are text-only and require Thinking by default. Native context reaches 262,144 tokens and can be extended to roughly 1,010,000 tokens. The hosted Qwen 3.8 Max is a different configuration. Its model card says it adds vision input, switchable Thinking, a default 1M context, and built-in tools.
