Qwen3-235B-A22B-Thinking-2507

OPEN

Alibaba · Qwen3 family · released Jul 25, 2025

Paired always-on reasoning ('Thinking-only') sibling of Qwen3-235B-A22B-Instruct-2507, released 4 days later. Enforces <think> mode, extends max output to 81,920 tokens, native 262,144-token context. Same 235B/22B-active MoE backbone as the Instruct-2507 release already in corpus, but a distinct fine-tune (not a shared-weights effort tier), so tracked as its own standalone entry.
