Qwen3.8-Max-0902 gains 22 points on CodeArena without a new model

On September 2, 2026, Alibaba shipped Qwen3.8-Max-0902, a post-trained snapshot of Qwen3.8-Max that climbs to 1,691 on CodeArena without touching its 2.4-trillion-parameter base. Teams evaluating coding agents now have to track a cadence of dated snapshots rather than model launches.
