Language models

Multiple models, each with different capabilities and price points. Prices are per 1,000 tokens. You can think of tokens as pieces of words, where 1,000 tokens is about 750 words. This paragraph is 35 tokens.


With broad general knowledge and domain expertise, GPT-4 can follow complex instructions in natural language and solve difficult problems with accuracy.

Fine-tuning models

Create your own custom models by fine-tuning our base models with your training data. Once you fine-tune a model, you’ll be billed only for the tokens you use in requests to that model.

Base models

GPT base models are not optimized for instruction-following and are less capable, but they can be effective when fine-tuned for narrow tasks.

512×512$0.018 / image
256×256$0.016 / image

Audio models

Whisper can transcribe speech into text and translate many languages into English.
Whisper$0.006 / minute (rounded to the nearest second)

Older models

We continue to improve our models and periodically retire older, less used models.

Usage quotas

When you sign up, you’ll be granted an initial spend limit, or quota, and we’ll increase that limit over time as you build a track record with your application. If you need more tokens, you can always request a quota increase.
