DeepSeek

DeepSeek is a Chinese AI research lab that has gained massive global attention with its open-source large language models that rival proprietary systems at a fraction of the training cost. DeepSeek-R1, their reasoning-focused model, demonstrated that chain-of-thought reasoning could emerge through reinforcement learning alone, matching or exceeding the performance of models like OpenAI o1 on math and coding benchmarks. The DeepSeek-V3 model serves as their general-purpose flagship, delivering strong performance across multilingual understanding, code generation, and analytical tasks. What makes DeepSeek remarkable is their efficiency innovations including Multi-head Latent Attention and DeepSeekMoE architecture, which dramatically reduce training and inference costs. All major models are released under permissive open-source licenses, allowing unrestricted commercial use and self-hosting. The platform offers both a free web chat interface and an API service with pricing that significantly undercuts competitors. DeepSeek models are available through major cloud providers and can be run locally using frameworks like Ollama and vLLM, making advanced AI capabilities accessible to individual developers and smaller organizations.
