Every model, with its real price.

Free open models (41)

$0 input and $0 output, served on NVIDIA NIM. A new trial key can call these without a card. If yours returns a 402 here, your account already started checkout at some point and needs it finished before free calls resume.

Premium text models (55)

Billed from your balance at the provider's published rate, cheapest input first. A trial key cannot call these until you add a card. The IDs below already include the provider prefix they need (openai/, anthropic/, or gemini/). Our catalog stores them bare, because that is the key we price against once the prefix has been read off. Sent that way, as gpt-4o rather than openai/gpt-4o, they route to the free NVIDIA tier. The reply does say so: its model field names the model that actually answered, so compare it against the ID you sent. What you will not get is an error or a warning header, so code that never reads response.model will not notice.

Image, video, and audio (39)

Billed per image or per second of output rather than per token.
