Doubao 2.1Pro 0915 version launch enhances stability and multimodal capabilities

On September 16, ByteDance's Volcano Engine announced the release of the Doubao-Seed-2.1-pro model in its 0915 version. The API is now available on ByteDance's Zhuanyu platform, with the Doubao work client updated to support the new version. TRAE has also been synchronized, allowing seamless migration for enterprises without changing API access points. The 0915 version improves agent task delivery, enhancing evidence traceability, authoritative source retrieval, and data verification to reduce model hallucination. It supports complex analytical tasks like financial research and office automation, producing structured expert drafts. Multimodal coding capabilities have also been strengthened, enabling the model to understand and resolve cross-file programming issues, and convert visual information into code for Web3D and game development. Video reasoning has seen significant improvements, allowing precise evidence location and SOP comparison. The model now excels in professional fields like education, engineering, and medicine. Token efficiency has also been optimized, reducing inference rounds and operational costs for image and video processing tasks.
