DeepSeek AI · General LLM
DeepSeek
A Chinese AI lab producing highly efficient open-source models that achieve frontier performance at a fraction of the training cost of competitors.
Overview
DeepSeek has gained significant attention for producing models that rival GPT-4 and Claude performance at dramatically lower training costs. DeepSeek-V2 introduced a multi-head latent attention mechanism and DeepSeekMoE architecture that substantially reduce inference costs. DeepSeek-Coder is among the top coding models, while DeepSeek-R1 demonstrates strong reasoning capabilities. The company's ability to achieve near-frontier results with efficient architectures has challenged assumptions about the compute required for top-tier AI performance.
