DeepSeek-V3 / R1

OSS

Rivals GPT-4; R1 = chain-of-thought reasoning

DeepSeek-V3 is a 671B Mixture-of-Experts model that benchmarks close to GPT-4, while R1 adds chain-of-thought reasoning for math and coding tasks. The open weights and MIT license make it one of the most capable freely available models. Best for researchers and developers who need frontier-level reasoning on their own hardware.
