## About Qwen3-Max

Qwen3-Max, released September 24, 2025 at Alibaba's Apsara Conference, was the first Qwen model to cross a trillion parameters — and it stayed closed, available only through the Alibaba Cloud API with no weights published, continuing the pattern Qwen2.5-Max had set that January. For a lab whose reputation had been built almost entirely on open releases, keeping the largest models proprietary was a deliberate repositioning rather than an oversight.

It was trained on roughly 36 trillion tokens and carried a 256K-token context window. The split it cemented — a proprietary Max tier at the top, open weights underneath — became the shape of Qwen's lineup from then on, with Qwen3.5-Plus, Qwen3.6-Plus and the Qwen3.7 pair all following the same commercial pattern while the numbered open releases continued in parallel. A reasoning variant, Qwen3-Max-Thinking, was added later.
