About DeepSeek-V4-Pro-0813
DeepSeek-V4-Pro-0813, released August 13, 2026, brought the top tier of the V4 line up to the agentic post-training that had landed on Flash two weeks earlier. On DeepSeek's own harness it scored 87.9 on Terminal-Bench 2.1, against 82.7 for V4-Flash-0731 and 72.1 for the April V4-Pro-Preview build, and 83.3 on CyberGym — the highest figure in the lab's launch comparison at the time, marginally ahead of Claude Fable 5. It also posted 42.7% on Humanity's Last Exam without tools and 60.0% with them, 74.1 on Toolathlon-Verified and 31.8 on the public AutomationBench split. As with the July Flash release, DeepSeek ran the code-agent evaluations through its own unreleased harness in minimal mode, and its numbers for rival models did not always match those labs' published figures, so the chart reads best as a within-family comparison.
The headline changes were operational rather than architectural. V4-Pro and V4-Flash both gained a selectable reasoning effort — low for simple prompts, high for everyday agent work, max for hard tasks — replacing the single fixed thinking budget of the earlier builds, and the release added native OpenAI Responses API support with one-click Codex setup. Distribution followed the pattern the Flash refresh established: the checkpoint reached the app and web product under an "Expert Mode" toggle and shipped through the API under unchanged model names, so existing callers were moved onto it without a code change. DeepSeek's launch post listed app, web, and API availability only, and announced no accompanying weight release.
