Models
DeepSeek R1DeepSeek R1 (671B total, 37B active MoE) is a reasoning model that uses chain-of-thought with <think> tags to solve complex problems. Excels at math, coding, and scientific reasoning tasks with transparent step-by-step thinking.DeepSeek V3.1DeepSeek V3.1 is a hybrid model supporting both thinking and non-thinking modes. Features enhanced tool calling capabilities for agent-based tasks. Thinking mode maintains answer quality comparable to DeepSeek-R1 with improved response times.DeepSeek V3.1 TerminusDeepSeek V3.1 Terminus — refined variant of V3.1 optimized for tool calling and structured generation tasks.DeepSeek V3.2DeepSeek V3.2 (685B total, 37B active MoE) harmonizes high computational efficiency with superior reasoning and agent performance. Features DeepSeek Sparse Attention for long-context efficiency and a scalable reinforcement learning framework. Excels at long-context reasoning, tool-using agents, function calling, JSON output, and FIM.DeepSeek V3.2 ExpDeepSeek V3.2 Exp — experimental variant of V3.2 with enhanced general-purpose capabilities. Strong at tool use, structured output, and multi-turn conversation.DeepSeek V4 FlashDeepSeek V4 Flash — fast, cost-efficient model with 1M context window. Supports reasoning, tool calling, and structured output.DeepSeek V4 ProDeepSeek V4 Pro — high-capability model with 1M context window. Superior reasoning, coding, and agent performance with tool calling and structured output.
