Models
Use documented model IDs in requests. Aliases are accepted for common model names, but exact IDs are best for automation and reproducible routing.
Claude and Fable
Claude models use Anthropic-compatible routes. Fable keeps the public Anthropic-compatible model ID while routing generation through OpenAI providers.
| Model | Family | Endpoints |
|---|---|---|
anthropic/claude-opus-4.8 | Opus 4.8 | /v1/messages, /v1/chat/completions |
anthropic/claude-opus-4.7 | Opus 4.7 | /v1/messages, /v1/chat/completions |
anthropic/claude-sonnet-5 | Sonnet 5 | /v1/messages, /v1/chat/completions |
anthropic/claude-haiku-4.5 | Haiku 4.5 | /v1/messages, /v1/chat/completions |
anthropic/fable-5 | Fable 5 | /v1/messages, /v1/chat/completions, /v1/responses |
GPT
GPT models use OpenAI provider routes and are available through OpenAI-compatible endpoints.

Open Model Groups
Open model-group IDs route through the configured external/open provider paths for the matching route.
