DeepSeek V4-Flash-0731 Public Beta: Code Agent Capabilities Significantly Enhanced, Price Unchanged
DeepSeek officially launches the public beta of version V4-Flash-0731. Through post-training and Agent framework optimization, DeepSWE benchmark scores have improved from 7.3 to 54.4, Cybergym scores have doubled to 76.7, and performance on some hard benchmarks approaches Claude Opus 4.8. The new version does not increase parameters, prices remain unchanged, it natively supports the Responses API, and existing user APIs will automatically switch to the new version. Currently, only the Flash API is updated; the V4 Pro official version is still under development.
