DeepSeek-V3.1 is a 671B-parameter hybrid reasoning model (37B active) with thinking and non-thinking modes selected through prompt templates. It extends DeepSeek-V3 with two-phase long-context training (up to 128K tokens) and uses FP8 microscaling for efficient inference. The model does well at tool use, code generation, and reasoning, with performance comparable to DeepSeek-R1 and faster responses. It supports structured tool calling, code agents, and search agents, which suits research and agentic workflows. It succeeds DeepSeek V3-0324.

Throughput is how fast the model writes (tokens per second, higher is better). Time to first token is how long before the answer starts (lower is better).
