Qwen3.8-Max: 2.4T-parameter open-source model sets a new bar for coding and cowork

Qwen3.8-Max 发布：开源最强编码与协作模型，2.4T 参数

Qwen released Qwen3.8-Max, a 2.4T-parameter model (95B active) with open weights coming next week. It handled three long-horizon tasks without human help: a 16-day autonomous coding run that built a self-evolving CLI harness from scratch (265 commits, 127 PRs); a ~5-day research reproduction where it wrote 7,600 lines of code, ran 33 GPU training rounds, matched all six findings of a paper, then invented a method that beat the paper's own AIME24 score by +2.7 points; and a 24-hour contest entry that outperformed 526 human teams on Alibaba Cloud's Tianchi platform. These are self-reported results—community replication after the weight release will be the real test.

Why it matters: Qwen's first open-weight Max-class model at 2.4T total / 95B active params, demonstrated via three zero-human-intervention long-horizon tasks (16-day autonomous coding with 265 commits, 5-day paper reproduction with 7,600 lines of code) instead of benchmark tables. A Chinese f...
