🚨UPDATE: StepFun’s STEPX Neo, its first agent-native smartphone, is launching on Oct. 13 at 7 PM Beijing time. It runs Step AOS with the built-in Amoo AI agent. One command can sync documents, generate a presentation, or even dispatch a delivery service to send a file to a specific location. Take a photo of a concert poster, and Amoo can identify the event, help with ticket booking and trip planning, and even draft a leave request. STEPX Neo has passed L3 testing under China’s national AI terminal intelligence grading standard. It also features a transparent dual-tone design, dual rear cameras, a large matrix camera module, and a secondary display.

I visited @StepFun_ai's Shanghai office yesterday and had such a great time. Everyone was so welcoming, and they handled even my tougher questions with a smile. A powerful new model from StepFun might be just around the corner 👀👀 Thanks to @cherry_gong3 for inviting me!

Meta's big model drop pulled the attention away from @StepFun_ai and everything else that shipped this week. But the thing is that a lot of frontier models look tuned to the benchmarks they get judged on, and a release chart can't tell you whether that's what you're looking at. I personally like to see the same tasks and the same harness, on the hardware people actually run.
