One model, not a menu
Leaderboards and catalogs list hundreds of models. You describe the need (a task or a purpose, the capabilities it requires, a budget) and get one answer, with the reason and the next alternatives.

Live API · no account needed
Try it live
Ask the real API one of these, and see the model it picks, where to call it and what a call costs. Sandbox calls aren't tied to an account.

Why it exists
How it compares
Other tools pick one model for everyone, or route each request through their own account. This one answers for your providers and stays out of the request path.
The cheapest provider for it
The same model is often sold by its maker, a cloud platform and a router at different prices and fees. You get the cheapest offering that has every capability you asked for, and the others as fallbacks.
Your providers only
You list the providers you have accounts with. A model you can't call is never proposed, and the answer names it exactly as that provider's API expects it. Your provider keys never leave your servers.
