DeepSeek is a Chinese AI lab that has released competitive open-weight models rivaling frontier closed models at dramatically lower training costs. DeepSeek R1 and V3 demonstrated that mixture-of-experts and reinforcement learning at scale can close the gap with GPT-4-class models. Models are freely available via Hugging Face and a low-cost API.
