On December 9, Alibaba's Tongyi Qianwen officially rolled out Qwen Code v0.3.0. This latest iteration is centered around four major enhancements: expanded functionality, robust language internationalization, heightened security and stability, and improved ecosystem compatibility. The updated version debuts a Stream JSON mode, which allows for streaming and structured output, thus elevating the standardization of inputs for intricate tasks. It comes equipped with a built-in Chinese-English bilingual interface, facilitating effortless one-click switching between UI languages and model output languages, as well as the capability to load personalized language packs. Beyond that, it fortifies memory safety, ensures coding compatibility with Windows, and refines the authentication system, all while streamlining the CI/CD testing pipeline. Moreover, it introduces support for ModelScope Provider, enhances the handling of stream_options, and addresses several critical issues.
