Skip to main content
The AI Gateway maintains a catalog of known providers and models. This catalog enables automatic provider inference, model validation, and rich metadata for selection strategies.

​
How the catalog works

When you send a request with a model name like gpt-4o, the gateway:
  1. Looks up the model in the catalog
  2. Identifies the provider (OpenAI)
  3. Routes the request to the appropriate provider endpoint and injects the API key
  4. Applies any configured selection strategies
You can also explicitly specify providers using the provider:model format (for example, openai:gpt-4o).

​
Providers

OpenAI and Anthropic are available with AI Gateway API Keys—no provider account needed. All other providers require you to bring your own key.

Using models from the catalog

​
Simple model reference

Reference models directly by their ID: 
{
  "model": "gpt-4o",
  "messages": [{"role": "user", "content": "Hello"}]
}

​
Explicit provider

Use the provider:model format for explicit routing: 
{
  "model": "openai:gpt-4o",
  "messages": [{"role": "user", "content": "Hello"}]
}

​
Custom providers and models

You can extend the catalog by configuring custom providers in your Traffic Policy. See Custom Providers for configuration details. 
providers:
  - id: "custom-ollama"
    base_url: "https://ollama.internal"
    models:
      - id: "llama3"
      - id: "mistral"

​
Catalog updates

The model catalog is updated periodically to include new models and providers. For immediate access to models not yet in the catalog, add them explicitly to your provider configuration.

​
Aliases reference

Model and provider names are not case-sensitive. For example, gpt-4o, GPT-4o, and Gpt-4O all resolve to the same model. The following aliases are available in addition to the primary IDs listed above.
