DeepSeek

DeepSeek is an artificial intelligence research and development organization that focuses on building large language models and agent systems. Founded in 2023, it has released multiple open‑source foundation models covering general‑purpose text reasoning, code generation, mathematical problem solving, vision‑language understanding, and Mixture‑of‑Experts architectures. The platform offers a free conversational interface through its web application and mobile app, where users can interact with the latest flagship model (DeepSeek‑V4) in real time. This model delivers world‑class reasoning performance and enhanced agent capabilities, enabling it to break down complex tasks, call external tools, and execute multi‑step workflows autonomously. DeepSeek provides an API platform that allows developers and businesses to integrate these models into their own applications. The API supports a range of endpoints, from simple chat completions to advanced function calling, enabling tasks such as customer support automation, code review, document summarization, data extraction, and educational tutoring. The models are built on a custom training framework and leverage a large‑scale self‑built computing cluster with thousands of GPUs, which allows faster iteration and lower inference costs. The organization has also open‑sourced several model checkpoints, including DeepSeek‑LLM (a general‑purpose language model), DeepSeek‑Coder (specialized for code generation and understanding), DeepSeek‑Math (trained for mathematical reasoning and problem solving), DeepSeek‑VL (a vision‑language model that processes images and text jointly), and DeepSeek‑MoE (the first open‑source MoE model in China). These models are available under permissive licenses and have been adopted by researchers and develope
