Qwen3.8-Max Announced at 2.4T Parameters With No Benchmarks

Alibaba announced Qwen3.8-Max, its largest model at 2.4 trillion parameters, and published no benchmark names, scores, harness or methodology. The claims are about duration instead: 10+ days of self-evolving development from empty folder to production, 500+ turns of chip design optimisation, and a 365-day e-commerce strategy loop. The preview is closed, served as qwen3.8-max-preview through Token Plan, Qoder and QoderWork; open weights are promised “next week” with no date, licence or repository, and the context window is undisclosed. A circulated claim that it ranks second only to the current frontier leader has no public table behind it. The more consequential line: Qwen3.8-27B is also going open-weights.
