Compatible with the OpenAI API and the Anthropic API

One endpoint, the whole catalogue, a single API key.

Cerbero sits in front of several frontier providers and serves them as if they were one. You do not change library or the way you call: you change the base URL and carry on working.

Available models

This list comes from the live catalogue of the service, not from a hand-written copy. Any of these names works as-is in the model field of your call.

Status and response time are measured by our own probe every few minutes with a real request. Response is how long a short request takes end to end, not generation speed: most of that time is start-up, so a slow response does not mean the model writes slowly.

Plans

The quota counts requests, not tokens, on a rolling 24-hour window. It does not reset at midnight: each request frees its own slot 24 hours after it was made.
