Qwen4-Max Enters Preview With a Runtime
Alibaba ships the model and an open agent harness in the same breath, which is the more consequential half.
Alibaba released a preview of Qwen4-Max on 12 November 2026, initially available through its Token Plan and within Qwen Office and Qoder, with improved coding and agentic capability. Alongside it, the company open-sourced Qwen Code 1.0 Preview, which folds in harness capability so developers can wire their own tools and embed agents into products. Users logging into Qoder between 11 and 24 November receive a 30-day free allowance. The pattern follows a wider shift in China’s model market: the harness, not the model, is what lowers the barrier for small teams building agent products.
