# List models

List the LLM models available to your organization.





Returns the LLM catalog. The `id` of each entry is a model slug (for example `opus-4.5`, `sonnet-4.6`, `claude-opus-4-7`) — pass it as `entity_id` when assigning an `llm_model` via [`POST /agents/{agent_id}/resources`](/api/agent-resources/assign).

```http
GET /api/public/v1/models
```
