Overview
- StepFun unveiled the StepX Neo at a Shanghai event on Monday and billed it as an 'agentic' smartphone built around Step AOS, an on-device agent called Step Amoo, and an on-device LLM named Step Edge.
- The company claims Step Amoo can run offline, recall memory in roughly 15 milliseconds, and keep personal data on the device while using cloud services only for complex tasks.
- StepFun says Step Edge tops 29 “authoritative” benchmarks but has not named the specific tests, provided model sizes, or released independent verification of those rankings.
- The firm described Step AOS as a blend of Android, Linux and RTOS to host agents, though reporters note it is unclear whether Step AOS is a full independent operating system or an Android-based skin.
- StepFun showed teaser videos and a China-focused partner list including Alipay, Baidu, Meituan and Didi, but gave no full hardware specs or clear manufacturing details and appears likely to rely on an ODM for production.
