The DeepSeek-V2 model
In May 2024, DeepSeek-V2 appears with You among its authors as a Mixture-of-Experts model with 236B total parameters and 21B activated for each token.
-
June 2024
The DeepSeek-Coder-V2 model
In June 2024, DeepSeek-Coder-V2 appears with You among its authors. The code model is further pre-trained from an intermediate DeepSeek-V2 checkpoint on six trillion additional tokens.
