Models
LLMRPM currently supports 75 models across 18 providers. Every model in the catalog is reachable through the same chat completions and Messages endpoints — you select one by its public model ID.
Using model IDs
Set the model field in your request body to any ID from the model catalog. Switching models is a one-line change — no separate credentials, no provider-specific request shape.
List models
Query the models available to your key programmatically instead of hardcoding the catalog:
curl https://llmrpm.com/api/v1/models \
-H "Authorization: Bearer $LLMRPM_API_KEY"Response shape
GET /api/v1/models returns a standard OpenAI-style model list — an object: "list" wrapper around a data array, where each entry has at least an id you can pass straight into model on a chat completions or Messages request. For descriptive fields — display name, provider, context window, and capabilities like streaming or tools — use the model catalog page, which LLMRPM curates and keeps human-readable.
