DeepSeek API

Access DeepSeek's high-performance LLMs, including the DeepSeek-V3 (deepseek-chat) and DeepSeek-R1 (deepseek-reasoner) models, via a robust, OpenAI-compatible RESTful API.

The DeepSeek API provides direct access to two flagship models: the general-purpose DeepSeek-V3 (deepseek-chat) and the specialized DeepSeek-R1 (deepseek-reasoner). DeepSeek-V3 handles conversational tasks and supports a 128K context window; DeepSeek-R1 excels at complex mathematical reasoning and structured logic. The API is designed for simple integration, offering full compatibility with the OpenAI API format and supporting essential developer features like structured JSON output and Function Calling (on deepseek-chat).
