Qwen3.8 Max
Reached GA on 3 Aug 2026 and, around 12–14 Aug, became the first Qwen-Max-class model Alibaba has ever open-weighted — following its 19 Jul preview at WAIC Shanghai. Still a 2.4T-parameter sparse MoE (active-parameter count undisclosed), but treat the hosted API and the open weights as two different products: the published checkpoint is reportedly text-only, dropping the vision and 1M-context features the hosted API keeps. Weights ship under a new custom revenue-share license, not Apache 2.0 — large commercial 'model-as-a-service' deployments above an unspecified threshold need a separate agreement with Alibaba, so check the license before redistributing. Vendor-reported scores at GA: Terminal-Bench 2.1 86.6 (vs. Claude Opus 4.8/Fable 5 at 84.6, GPT-5.6 Sol at 88.8), SWE-bench Pro 67.7, GPQA Diamond 92.6, DeepSWE 1.1 56.6 (up from 21.6 on Qwen3.7 Max) — independent Arena/AA verification is still catching up as of 17 Aug 2026, though early Arena placement (~1491) already makes it the highest-ranked open-weight model on the board. Hosted API pricing dropped from the preview placeholder to $2/$6 per 1M tokens ($0.25 cached).
