DeepSeek-Prover-V2-671B – An open-source mathematical reasoning large model launched by DeepSeek

What is DeepSeek-Prover-V2-671B

DeepSeek-Prover-V2-671B is a large-scale language model focused on mathematical reasoning, released by DeepSeek on the Hugging Face open-source platform. With 671 billion parameters, it is an upgraded version of last year’s Prover-V1.5 model for mathematical AI.

The model features a cutting-edge Multi-head Latent Attention (MLA) architecture, which significantly reduces memory usage and computational overhead during inference through KV Cache compression. It supports multiple computation formats including BF16, FP8, and F32, allowing for faster and more resource-efficient training and deployment.
