OpenAI releases GPT-5.5 Instant, with more concise answers

No more five-page essays when you need a simple answer. (Picture: generated)
Replacing GPT-5.3 Instant as the «daily driver» for hundreds of millions of users, the new model touts major changes to common gripes.

For those fed up with three-page essay responses to simple questions, the new model should offer «clearer, more concise answers,» with «stronger» and «tighter» responses that are more «to-the-point.» This should reduce the need for frequent follow-up questions, OpenAI says.

OpenAI says the new Instant will be «more effective» at leveraging history from previous chats, files and Gmail. It should also be showing you its sources when it uses memories.

Hallucinations are supposedly also way down, reducing the rate by 52.5% in internal tests, while inaccurate responses dropped by 37.3%.

The model will become the default option for most ChatGPT users on the Plus and Pro tiers, and is rolling out «over the next two days.» Other plans should get it «soon.»
