OpenAI’s GPT-5 Met With Mixed Reviews, Confusion in First Day

For months, OpenAI Chief Executive Officer Sam Altman has been hyping up the capabilities of GPT-5, setting up the launch as a seminal moment for the company. But in the first 24 hours after its release, the new model was met with mixed reviews.

In its announcement Thursday, OpenAI said GPT-5 was better at coding and reasoning through complex problems, and touted it as advanced enough to turn chatbot ChatGPT into a Ph.D.-level expert. Some with early access praised the model, with caveats. “It’s my new favorite model,” developer Simon Willison wrote in a blog post, calling it “competent” and “occasionally impressive.” He added: “It’s not a dramatic departure from what we’ve had before.”
