Qwen3.6-27B
Dense 27B Qwen that beats its 14x-larger sibling on SWE-bench Verified — 77.2%.
About
Qwen3.6-27B (March–April 2026) is the efficiency story of the Qwen 3.5/3.6 generation: a dense 27B-parameter open-weight model that beats the 397B-parameter MoE flagship Qwen3.5-397B-A17B on SWE-bench Verified, 77.2% versus 76.2%, per Alibaba's own model cards (provider-reported). It anchors the current open-source coding-agent stack in several 2026 guides, typically deployed behind coding agents for real software-engineering work while larger or more multimodal models handle other surfaces. Exact release day within the March–April window was not verified in the sources read, so the date is left null. As with all vendor benchmark claims, independent reproduction on your own tasks is the only number that matters.
