DeepSeek R1 is DeepSeek's strongest model for complex reasoning, math, and science tasks. DeepSeek V3 is the best general-purpose DeepSeek model for coding and writing. Both are MIT licensed and free to run.
DeepSeek R1 matches GPT-5.4 on many reasoning benchmarks at a fraction of the cost. Claude Opus 4.7 still leads on SWE-Bench Pro coding. The key advantage of DeepSeek is MIT licensing — you can run it for free via Groq, Together AI, or self-hosted.
DeepSeek models are open-weight and can be self-hosted, giving full control over data. The API (api.deepseek.com) processes data through DeepSeek's servers in China — teams with data residency requirements should use self-hosted deployments or US-based providers like Groq or Together AI instead.
Open-source reasoning model that matches o1-class performance on math, science, and complex coding at a fraction of the cost — the best open alternative to proprietary reasoning models.
