DeepSeek-V4-Pro-Base is the base (non-instruction-tuned) checkpoint of DeepSeek's V4-Pro series, a Mixture-of-Experts model with 1.6 trillion parameters (49B active) and a 1M-token context. Weights are hosted on Hugging Face (deepseek-ai) in FP8 mixed precision; the base checkpoint itself has no model card there. The V4 series is licensed under MIT.
