DeepSeek V4 Pro 0813 was released August 12, 2026 as the general-availability checkpoint of DeepSeek's V4 Pro, ending a preview period that ran close to four months. DeepSeek describes it as superseding the preview build, with greatly enhanced agentic capabilities and improvements that show up most in production environments.

The architecture is a mixture-of-experts design with 1.6 trillion total parameters and 49 billion active per token, combining two attention variants DeepSeek calls Compressed Sparse Attention and Heavily Compressed Attention. Together they cut per-token inference compute and KV cache substantially at the million-token setting, which is what makes a context window of 1.0M tokens practical rather than theoretical.

DeepSeek V4 Pro 0813 keeps thinking and non-thinking modes, tool calls, and up to 1.0M tokens per response. On vendor-reported results it scores 87.9 on Terminal Bench 2.1, 74.1 on Toolathlon-Verified, and 80.6 on SWE-bench Verified. Independent evaluators have not replicated those figures for this build.

You can integrate DeepSeek V4 Pro 0813 through AI SDK, Chat Completions API, Responses API, Messages API, or other API formats, from TypeScript or Python.
