Released 72 days after Qwen3.7-Plus · All Alibaba releases
Qwen3.8-2.4T-A95B is Alibaba's open-weight publication of its Max tier flagship, released in August 2026 and, at 2.4 trillion total parameters, the largest open-weight language model published to date. A sparse Mixture-of-Experts design activates roughly 95 billion parameters per token, paired with a hybrid attention stack that holds latency and compute well below a dense model of comparable size. This is the first time Alibaba has opened a Max tier model's weights, and the checkpoint is not identical to the managed service: the downloadable build is text only and always runs in thinking mode, while hosted Qwen3.8-Max adds vision input, a non-thinking mode and built-in tools. Native context is 262K tokens, extensible past 1 million, and it runs on standard inference stacks including vLLM and SGLang, which suits teams that want a frontier-scale open model they can host and adapt themselves.
