About
DeepSeek-V3.1, released by DeepSeek in August 2025, is an updated model in the V3 series combining strong coding, instruction-following, and reasoning in an open-weight format. It continues DeepSeek's approach of releasing competitive large-scale models openly — a strategy that positioned the lab as a significant contributor to the open-weight model ecosystem and drew developer adoption across agentic coding and general-purpose API applications.
