Overview

DeepSeek became famous overnight by proving that frontier-level models could be trained at a fraction of the expected cost — and released with open weights under an MIT license. Its R1 reasoning models and V3 general models power a free assistant and one of the cheapest APIs on the market. For teams wanting to self-host a top-tier model, DeepSeek is a reference choice.
