here is GPT-4, our most capable and aligned model yet. it is available today in our API (with a waitlist) and in ChatGPT+. it is still flawed, still limited, and it still seems more impressive on first use than it does after you spend more time with it.

it is more creative than previous models, it hallucinates significantly less, and it is less biased. it can pass a bar exam and score a 5 on several AP exams. there is a version with a 32k token context.
we are previewing visual input for GPT-4; we will need some time to mitigate the safety challenges.
we now support a “system” message in the API that allows developers (and soon ChatGPT users) to have significant customization of behavior. if you want an AI that always answers you in the style of Shakespeare, or in json, now you can have that.
we are open-sourcing OpenAI Evals, our framework for automated evaluation of AI model performance, to allow anyone to help improve our models.
we have had the initial training of GPT-4 done for quite awhile, but it’s taken us a long time and a lot of work to feel ready to release it. we hope you enjoy it and we really appreciate feedback on its shortcomings.
