Custom Providers

Crush supports custom provider configurations for both OpenAI-compatible and Anthropic-compatible APIs.

NOTE

Note that we support two "types" for OpenAI. Make sure to choose the right one to ensure the best experience!

• openai should be used when proxying or routing requests through OpenAI.
• openai-compat should be used when using non-OpenAI providers that have OpenAI-compatible APIs.

OpenAI-Compatible APIs

Here's an example configuration for Deepseek, which uses an OpenAI-compatible API. Don't forget to set DEEPSEEK_API_KEY in your environment.

provider add deepseek --type openai-compat \
  --base-url "https://api.deepseek.com/v1" \
  --api-key "$DEEPSEEK_API_KEY"

model add deepseek/deepseek-chat \
  --name "Deepseek V3" \
  --context-window 64000 \
  --default-max-tokens 5000 \
  --price-input 0.27 \
  --price-output 1.1 \
  --price-cache-create 1.1 \
  --price-cache-hit 0.07

Anthropic-Compatible APIs

Custom Anthropic-compatible providers follow this format:

provider add custom-anthropic \
  --type anthropic \
  --base-url "https://api.anthropic.com/v1" \
  --api-key "$ANTHROPIC_API_KEY" \
  --extra-header anthropic-version 2023-06-01

model add custom-anthropic/claude-sonnet-4-20250514 \
  --name "Claude Sonnet 4" \
  --context-window 200000 \
  --default-max-tokens 50000 \
  --can-reason true \
  --supports-images true \
  --price-input 3 \
  --price-output 15 \
  --price-cache-create 3.75 \
  --price-cache-hit 0.3
