Alibaba has released Qwen3.8-Max, a 2.4-trillion-parameter mixture-of-experts model (95 billion active per token), two weeks after its preview. Company benchmarks show it beating GPT-5.6 Sol on instruction following and research-style tasks while still trailing Claude Fable 5 on hard software engineering; the API costs $2 per million input tokens and $6 per million output, and open weights are promised within about a week. Alibaba's showcase: the model ran a software project autonomously for 10 days, opening its own issues, running tests and merging its own pull requests — and Alibaba shares jumped about 6% on the launch.
