Today is 5/5! GPT-5.5 shipped 12 days ago, and the community love has been amazing. ✨

Revisiting a few first impressions we hadn’t posted here before seeing more of you tonight at 5:55.

First: @clairevo gave GPT-5.5 a backlog of bugs, and it did “a 98% job all by itself.” pic.twitter.com/ZdOL8QGUii

Next: @willkoh_kc from @tryramp tested GPT-5.5 inside their own harness.

“It was discovering ways to use the tools that we had given it… and figuring out novel ways to solve problems.”

He also tested it on financial-doc evals: GPT-5.5 hit their highest perfect extraction rate. pic.twitter.com/4C1N8QIrsc

All benchmarks are flawed, but GPQA has been fairly consistent & highly correlated with other measured benchmars. I think it's a good way to see how far we've come that the free model from OpenAI, GPT 5.5 Instant, is at a level that even paid models did not reach until late 2025
