DeepSeek announced the public beta release of the DeepSeek-V4-Flash API via an API documentation release log. Agent capabilities have been significantly enhanced, with scores on multiple benchmark tests far exceeding those of the V4-Pro-Preview version. The official version natively supports the Responses API format and has been optimized for Codex. The model structure remains consistent with the Preview version, requiring only retraining.
