DeepSeek released previews of V4-Pro and V4-Flash, mixture-of-experts models (which use only part of the model for each step) with open weights on Hugging Face, so anyone can download them, and a one-million-token context window. V4-Pro has 1.6 trillion parameters, the numbers a model learns in training, with 49 billion of them active per token. DeepSeek said it beat all open models on maths and coding and trailed only Gemini 3.1 Pro on world knowledge.
