Input price
$3
Cost of the text, images and files you send to the model.

Max output

Longest single response the model can write.
Input types
—
What kinds of input the model understands besides text.
Tool use / function calling
Yes
The model can request calls to your functions/APIs with structured arguments, the basis of agents.
Guaranteed JSON output
—
The API can force the response to match a JSON schema you provide.
Extended reasoning
Yes
The model can 'think' step by step before answering, improving hard math/coding at extra cost and latency.
Open weights
No
The model weights are downloadable, so you can self-host it or switch hosting providers without changing models.
Typical latency

How long until the first useful output arrives. Lower is better for interactive apps; batch jobs rarely care.
