OpenAI has released a powerful new image- and text-understanding AI model, GPT-4, that the company calls “the latest milestone in its effort in scaling up deep learning.”

GPT-4 is available today to OpenAI’s paying users via ChatGPT Plus (with a usage cap), and developers can sign up on a waitlist to access the API.

Pricing is $0.03 per 1,000 “prompt” tokens (about 750 words) and $0.06 per 1,000 “completion” tokens (again, about 750 words), where “tokens” represent raw text (e.g. the word “fantastic” would be split into the tokens “fan,” “tas” and “tic”). Prompt tokens are the parts of words fed to the model while completion tokens are the content generated by GPT-4.

It’s been hiding in plain sight, as it turns out. Microsoft confirmed today that Bing Chat, its chatbot tech co-developed with OpenAI, is running on GPT-4. Other early adopters include Stripe, which is using GPT-4 to scan business websites and deliver a summary to customer support staff, and Duolingo, which built GPT-4 into a new language learning subscription tier.
