DeepSeek is a Chinese AI lab that released DeepSeek R1 and V3 — open-source large language models that rival GPT-4 and Claude in benchmarks at a fraction of the training cost. DeepSeek's models are available via API and for self-hosting, making them popular with developers seeking powerful, cost-efficient AI capabilities. The R1 reasoning model shocked the AI industry with its performance and efficiency.

The verdict
Our take on DeepSeek
DeepSeek is worth a look if you build on LLM APIs and care about cost and context length, and its OpenAI- and Anthropic-compatible endpoints make trying it cheap. Check its terms against your data requirements first, and budget for per-token billing rather than a flat plan.
