Introducing GPT-5.5—a new class of intelligence for real work. GPT 5.5 is built to understand complex goals, use tools, check its work, and carry more tasks through to completion. It marks a new way of getting computer work done. It excels at writing and debugging code, researching online, analyzing data, creating documents and spreadsheets, operating software, and moving across tools until a task is finished. GPT-5.5 is rolling out today for Plus, Pro, Business and Enterprise users across ChatGPT and Codex. We’re also introducing GPT-5.5 Pro for Pro, Business, and Enterprise users in ChatGPT.

Liam Price, a 23 year old just solved a math problem on which mathematicians were stuck for the past 60 years using nothing but a $20 ChatGPT subscription. He just casually feeds old math problems into AI to see what happens, something researchers have started calling "vibe maths." So he typed in Erdős Problem #1196, a number theory conjecture open since 1966, into GPT-5.4 Pro. The model spent 80 minutes reasoning and came back with what looked like a complete proof.
