Qwen Code 1.0 Preview
Alibaba released Qwen Code 1.0 Preview, which merges the agent harness from its Qoder product into the open-source Qwen Code project as an embeddable agent core.
The harness connects a model, its tools and the execution process, and developers can now embed it in their own products. Version 1.0 starts from an in-process, in-memory event bus and extends a unified event model toward multi-node operation, with reasoning orchestration separated from tool execution. Model access, sandbox resources and MCP configuration are each managed in one place.

Open-source code under Apache-2.0 on a separate preview branch of QwenLM/qwen-code, the stable 0.27 line stays. Alibaba has published no benchmarks or stable 1.0 date, and cost-saving claims are its own. This is a new 1.0 preview and distinct from the original June 2025 Qwen Code record.
