DeepSeek · DeepSeek-V4 family · released Jul 31, 2026

Retrained checkpoint of DeepSeek-V4-Flash published July 31, 2026, same 284B/13B architecture and API pricing as the April siblings. DeepSeek's own model card only reruns the launch-day agentic/coding table (Terminal-Bench 2.1, NL2Repo, CyberGym, DeepSWE) with an unreleased internal harness ('DeepSeek Harness'); general reasoning/knowledge benchmarks were not rerun and still carry April Preview values, so this row is coding/agentic-only evidence, not a full refresh. DeepSeek retired V4 Flash on Sep 10, 2026; the deepseek-v4-flash name now routes to V4.1-Flash.
