Alibaba releases qwen code 1.0, integrating qoder's harness capabilities open source

Alibaba officially announced the launch of Qwen Code 1.0 on November 11, integrating the Harness capabilities developed in Qoder and open-sourcing the combined framework. This release provides developers with a foundational layer for running Agents that can be embedded into their own products. Qwen Code 1.0 evolves from an in-process memory event bus toward a distributed model, introducing layered extensions for access, scheduling, and execution. This architecture enables a separation of reasoning orchestration from tool execution, moving the system from a single process with multiple sessions to multiple nodes supporting more sessions. The unified event mechanism establishes clear boundaries for capability expansion and resource management, allowing different processing units—such as models, sandboxes, and external extensions—to collaborate around events. This design facilitates easier scaling, centralized control, and cost management. The new open-source kernel merges Qoder and Qwen Code's Harness functionality, allowing developers to build Agent systems tailored to specific use cases by connecting AI programming abilities into comprehensive workflows. The Qwen Code 1.0 Preview is available in a separate branch, while the existing stable branch remains accessible.
