DeepSeek

The deepseek provider routes to DeepSeek’s models. DeepSeek exposes two compatible surfaces and crabllm uses both: an OpenAI-compatible endpoint for chat and streaming, and a native Anthropic-compatible endpoint for Anthropic-format passthrough. Authentication is a bearer token on both.

Configuration

[providers.deepseek]   # section name doubles as kind; add `kind = "deepseek"` only if you rename it
api_key = "${DEEPSEEK_API_KEY}"
models = ["deepseek-chat", "deepseek-reasoner"]

Defaults, no base_url needed:

• OpenAI-compatible: https://api.deepseek.com/v1
• Anthropic-compatible: https://api.deepseek.com/anthropic

Set base_url to override the origin (both endpoints derive from it).

Usage

Send requests in OpenAI format as usual — just set the model to a DeepSeek id:

curl http://localhost:8080/v1/chat/completions \
  -H "Content-Type: application/json" \
  -d '{
    "model": "deepseek-chat",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'

Anthropic-format requests are served natively by DeepSeek’s Anthropic-compatible endpoint rather than translated.

Supported Endpoints

• Chat completions (streaming and non-streaming)
• Anthropic Messages (native passthrough, streaming and non-streaming)
• Tool/function calling

Limitations

• Embeddings, image generation, and audio endpoints are not offered by DeepSeek.
