Pricing methodology

OneInfer compares only positive prices with the same billing unit. Per-minute, per-character, per-token, per-image, per-video, and per-second rates remain separate. Prices can change, so the current model page and console remain the source of truth.

Frequently asked questions

How are image classification prices compared?

These models are priced per second of compute, not per image, and compared by that rate. A call takes 30–70 ms when the model is warm and a second or more when it is not; usage.billed_seconds in each reply is the time charged.

How do I call an image classification model?

Send POST /v1/ula/classify-image with the model id, an image (a public https URL or a base64 data URL) and 2 to 100 distinct labels. Every label comes back with a score, best first.

Do I need to train the model on my labels?

No. These models are zero-shot: name any labels in the request, such as “a cat” or “a product photo”, and each is scored against the image as it is.
