DeepSeek API Integration: OpenAI & Anthropic Formats
Master DeepSeek API integration. OpenAI-compatible SDK configuration, Anthropic API format for Claude tooling, tool calls with thinking mode, strict JSON schema enforcement, and migration patterns from OpenAI and Anthropic.
DeepSeek's API is uniquely dual-format — it supports both OpenAI-compatible endpoints and Anthropic API format. This means you can use the OpenAI SDK with base_url=https://api.deepseek.com or the Anthropic SDK with base_url=https://api.deepseek.com/anthropic. Migration from either ecosystem is typically a single-line change.
But integration depth varies. The Anthropic format supports thinking mode, tool calls, and streaming — but ignores budget_tokens for thinking and cache_control. The OpenAI format supports JSON mode, FIM completion, and streaming. Tool calls in thinking mode have unique constraints around reasoning_content management. The pages in this section cover the full integration landscape.
Note:
LangChain compatible: DeepSeek works with LangChain out of the box. Just set the OpenAI-compatible base_url and api_key in your LangChain configuration.
