We just published a post on how we continuously harden ChatGPT Atlas (and other agents) against novel prompt-injection attacks. This is an ongoing security problem (and a frontier research problem!) and we’re investing heavily in automated red teaming, reinforcement learning,

we're open-sourcing a new frontier science eval in biology, chemistry, and physics. there are 2 tracks: olympiad level and advanced research level. as models become saturated on GPQA, this is a nice unsaturated alternative with clean test-time compute scaling. kudos to

The new ChatGPT Images is here. More precise edits, stronger instruction following, and up to 4x faster generation, while preserving details like lighting, composition, and likeness across edits. From quick fixes to full reimaginings, it’s easier to get exactly what you have in

Whoa. This new GDPval score is a very big deal. Probably the most economically relevant measure of AI ability suggesting that in head-to-head competition with human experts on tasks that require 4-8 hours for a human to do, GPT-5.2 wins 71% of the time as judged by other humans

Today we’re introducing GPT-5.2 in ChatGPT, our most advanced model series for professional work. GPT-5.2 Thinking is designed to help with real, economically valuable tasks — the kind of work professionals do every day: building spreadsheets and presentations, writing and

3/ We’re also teaming up with Rappi to help people try Go at no cost in Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Mexico, Peru, and Uruguay.

2/ ChatGPT’s weekly users in Latin America have nearly tripled year over year, and ChatGPT Go helps make it easier for even more people to benefit.

1/ We’ve expanded access to ChatGPT Go across more of Latin America, bringing an affordable way to use our most advanced AI tools to even more people in the region.

I'm seeing lots of confusion about ads rumors in ChatGPT. There are no live tests for ads – any screenshots you’ve seen are either not real or not ads. If we do pursue ads, we’ll take a thoughtful approach. People trust ChatGPT and anything we do will be designed to respect that.

@BenjaminDEKR I agree that anything that feels like an ad needs to be handled with care, and we fell short. We’ve turned off this kind of suggestion while we improve the model’s precision. We’re also looking at better controls so you can dial this down or off if you don’t find it helpful.

5/ Our focus now is to keep making ChatGPT more capable, continue growing, and expand access around the world — while making it feel even more intuitive and personal. Thanks for an incredible three years. Lots more to do!

4/ Search is one of the biggest areas of opportunity. ChatGPT now accounts for roughly 10% of search activity, and it’s growing quickly. As more people ask ChatGPT not just for answers but to take action on their behalf, we see lots of room to expand.

3/ Today, ChatGPT is the #1 AI assistant worldwide, with around 70% of assistant usage. New products are launching every week, which is great — it pushes us to move faster and keep raising the bar for what an AI assistant can do.

2/ Since then, people have used ChatGPT to learn new skills, build projects, start companies, and unlock creativity in ways we never anticipated. That’s what makes this work meaningful — the idea from the beginning was to put capability in people’s hands and see where they take

1/ Three years ago, we released ChatGPT as a public research preview at a time when similar AI systems mostly lived inside large companies. We did it because we believed anyone should be able to use advanced AI, not just a select few.

ChatGPT is 3 years old today!  We launched expecting a small research audience. Within hours, the usage was far beyond anything we’d prepared for. Since then, hundreds of millions of people have pushed us to make it more reliable, more capable, and more helpful. Thank you to

We’re making it easier to switch between voice and text. More to come!
