GPT-5.5 Instant is starting to roll out in ChatGPT.
It’s a big upgrade, giving you smarter, clearer, and more personalized answers in a warmer, more natural tone.
And it's also more concise, which we heard you wanted. We think you'll love chatting with it.
Huge heads-up. OpenAI has now launched a new landing page for ads https://t.co/picweBjNBa which includes a way to sign up, ads documentation, and a video guide h/t @juokaz
I just signed up and OpenAI needs to verify each advertiser (which can take some time they say). Go sign up now. :)
