DeepSeek

DeepSeek is an AI chat and developer platform that delivers high-performance large language models for reasoning, coding, and general assistance. The service combines an intuitive web chat experience with an OpenAI-compatible API, making it straightforward for individuals and teams to explore capabilities interactively and then integrate them into products. DeepSeek offers multiple models tuned for different tasks, including a general-purpose model for everyday writing and analysis, a reasoning-oriented model for multi-step problem solving, and a code model optimized for generation, refactoring, and debugging across popular languages.

Typical use cases include technical research, data exploration, drafting and editing content, building chatbots, automating support workflows, and accelerating software development. Developers benefit from streaming responses, tool/function calling, and robust documentation, while organizations can manage usage with organization keys, rate limits, and analytics.
