Models

Use the ID in the model field. Prices update live; every model has its own page with details, benchmarks and examples.

Chat models

Prices are per 1M input / output tokens. “Reads” is what you can send besides text: see Images, PDFs, audio and video.

Image models

Prices are per image. See Image generation and Image editing.

Video models

Prices are per second of video, by resolution. See Video generation.

Listing models from the API

Returns every model in OpenAI’s list format, with two extra fields: input_modalities (what the model reads) and, for image models, max_input_images. GET /v1/models/{id} returns one. Neither needs credit.

Retired models

When we retire a model, requests for it get a clear model_not_found error naming the models page. We announce retirements ahead of time where we can.
