Legacy values (openai, openai-compat, anthropic) are still accepted and migrated automatically.
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 completions \ --base-url "https://api.deepseek.com/v1" \ --api-key "$DEEPSEEK_API_KEY" model add deepseek/deepseek-chat \ --name "Deepseek V3" \ --context-window 64000 \ --default-max-tokens 5000 \ --price-input 0.27 \ --price-output 1.1 \ --price-cache-create 1.1 \ --price-cache-hit 0.07Anthropic-Compatible APIs
Custom Anthropic-compatible providers follow this format:
provider add custom-anthropic \ --type messages \ --base-url "https://api.anthropic.com/v1" \ --api-key "$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 \ --thinking toggleable \ --supports-images true \ --price-input 3 \ --price-output 15 \ --price-cache-create 3.75 \ --price-cache-hit 0.3Read this post in your terminal with glow:glow -p https://crush.charm.land/providers/custom.md
