GPT-5.1 is a great new model that we think people are going to like more than 5. But with 800M+ people using ChatGPT, one default personality won’t work for everyone. We launched new preset personalities so people can make ChatGPT their own.

First day as CEO of @instacart today. Every new hire answers the same question -- “What’s always in your cart?”; I bet you can guess my answer. Not pictured: the Nutella I put on top of the strawberries. Can’t wait to get started on this journey!

Apps coming to ChatGPT is a big deal. There’s something really magical about having a conversation with apps to guide the actions you want to take. We can’t even imagine what devs will create with a capability like this. It will be fun to see.
