Decision guidance
Fit the request contract before production.
Check before production
- Confirm the production client uses one of the listed request surfaces: /v1/chat/completions, /v1/responses, /v1/messages.
- Estimate a representative request from the current Free price fields instead of extrapolating from a tiny prompt.
- Check the observed-availability card and run your own timeout, retry, and fallback test before relying on the model.

DeepSeek V4 Pro 0813
DeepSeek V4 Pro 0813 is DeepSeek's large-scale Mixture-of-Experts (MoE) model and the general availability (GA) release of DeepSeek V4 Pro. It is designed for high-capability workloads requiring advanced reasoning, coding, and agentic task execution. As the production-ready V4 Pro release, it is well suited for complex software engineering, long-horizon agent workflows, and demanding reasoning tasks where reliability and model capability are critical.

DeepSeek V3.2 (Thinking)
DeepSeek-V3.2 is an efficiency-focused large model that combines strong reasoning with reliable tool use. It introduces DeepSeek Sparse Attention to lower compute costs for long contexts while preserving quality, and uses large-scale reinforcement learning to reach GPT-5-class reasoning (including top IMO/IOI results). An agentic task-synthesis pipeline improves how it reasons with tools in interactive settings — and developers can toggle reasoning on or off as needed.

DeepSeek V3.2 Speciale
DeepSeek-V3.2-Speciale is a high-compute edition of V3.2 built for top-tier reasoning and agent performance. Using DeepSeek Sparse Attention and extensive reinforcement learning, it surpasses GPT-5 on tough reasoning benchmarks and approaches Gemini 3 Pro–level capability, while still remaining strong at coding and tool use. It also draws on a large agent-training pipeline to boost reliability and generalization in interactive environments.

DeepSeek V3.1
DeepSeek-V3.1 is a hybrid reasoning model (671B total / 37B active) that supports switchable thinking and non-thinking modes. It extends DeepSeek-V3 with long-context training up to 128K tokens and efficient FP8 inference. It delivers faster performance while matching DeepSeek-R1 on tough reasoning and coding tasks, and supports structured tool use and agent workflows.
