I sat down with AI leaders from @figma, @box, @cognition, @tryramp, BAM, and the one and only @clairevo to hear how they’re using Astra. Optimizing GPU kernels, revamping workflows with computer use, designing many consistent screens… Amazed by what they’d done in just days! 🌌↗

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.”↗

One thing I love about our latest frontier models is their ability to seamlessly call tools within their reasoning flow. Web search is now supported in the API for o3, o3-pro, and o4-mini! 🌎🔎↗
