Overview
DeepSeek is a Chinese AI lab whose open-weight models, including DeepSeek-V3 and the R1 reasoning model, compete with leading proprietary models.
Its large mixture-of-experts models need multi-GPU hardware to self-host, so many people use them through hosted providers. Recent releases use the MIT licence.
