💥 It's here! GPT-5 is rolling out in ChatGPT for everyone, starting today. It's a 🤯 good model, and we've simplified the UI alongside it. No more choosing between gpt-4o and o4-mini. When you ask a hard question and the model needs to think hard, it does. When it can give you a fast answer, it does. It's an incredible writer, coder, thought partner, teacher, health advisor, assistant, and much more. It's the best thing we've ever built, and I can't wait to see what you think.
