Official listing: built and published by DeepSeek. More from DeepSeek
Serves DeepSeek models through OpenAI- and Anthropic-compatible APIs with thinking mode, tool calls, JSON output, and context caching, for developers using existing SDKs.
Skills
Thinking Mode
Enables model reasoning before the answer, with adjustable reasoning effort.
Tool Calls
Lets models call functions you define and return structured arguments.
JSON Output
Constrains responses to valid JSON for machine-readable results.
Anthropic API Compatibility
Accepts Anthropic-format requests at a dedicated base URL so Anthropic SDKs work unchanged.
Context Caching
Caches repeated prompt prefixes to reduce cost and latency on later requests.
