Sam Altman unveils the hotly anticipated GPT-4, an AI model he says ‘can pass a bar exam and score a 5 on several AP exams’

• OpenAI CEO Sam Altman unveiled the much-anticipated GPT-4 model.
• He said it is "still flawed, still limited," but can "pass a bar exam and score a 5 on several AP exams."
• The company said it is still "less capable than humans in many real-world scenarios."

OpenAI's hotly anticipated GPT-4 is here.

The company's chief executive officer Sam Altman described GPT-4 on Tuesday as an improved model that is "more creative" and "less biased" than earlier versions, and said it was capable of passing the bar exam for lawyers, and that it "could score a 5 on several AP exams."

The new model follows the rampant success of ChatGPT, which led OpenAI to roll out a subscription version it called ChatGPT plus, and other tech companies including Microsoft and Salesforce to announce projects with OpenAI to develop chatbots and other AI-driven technology.

Those who pay for OpenAI's ChatGPT Plus can give GPT-4 a whirl starting today, but there's a waitlist for the GPT-4 API.
