Alibaba Releases Qwen Code 1.0: Qoder and Qwen Code Harness Merged and Open-Sourced

November 11: According to IT之家 (ITHome), Alibaba announced the launch of Qwen Code 1.0 and the merged open-sourcing of Qoder and Qwen Code. Alibaba has integrated the Harness capabilities refined in Qoder into Qwen Code, released together with Qwen Code 1.0 Preview, providing developers with an Agent runtime foundation that can be embedded in their own products.

Qwen Code 1.0 starts from an in-process in-memory event bus and evolves toward a distributed architecture, expanding access, scheduling and execution in layers; through the "separation of hand and brain," inference orchestration and tool execution are managed independently. This release brings the Harness capabilities of Qoder and Qwen Code into a single open-source kernel. Harness is responsible for connecting models, tools and the execution process, and developers can use it to build Agent systems suited to their own scenarios. Qwen Code 1.0 Preview is released as a separate branch, while the existing stable branch is retained.
