智东西 · wechat · 2026-07-13

At its launch event, StepFun simultaneously introduced three core offerings: the agent-native operating system StepAOS, the personal agent Amoo, and the LLM-native AI terminal brand STEPX. The first smartphone, STEPXNeo, also made its debut. The company stated that it will continue to build out the agent ecosystem around this device, with more progress to be disclosed in 100 days.

The article highlights the system design of StepAOS: it emphasizes long-term memory, cloud-device collaboration, and cross-app scheduling, defining its security capabilities as "trusted, visible, controllable, and reversible." When executing tasks, the system determines whether to process primarily on-device or relay to the cloud based on task complexity, while opening atomic services to ecosystem partners. StepFun also announced ecosystem partnerships with apps like Alipay, Meituan, Amap, DiDi, JD.com, Baidu, Weibo, and WPS.

Regarding business positioning, StepFun stated that STEPX is not just about selling hardware, but aims to be an AI-native terminal brand. Yin Qi mentioned that future agent phones might no longer be high-frequency communication devices, but rather terminals that complete tasks for users through minimalist interaction. The article also noted that StepFun has completed a Series B+ funding round exceeding 5 billion RMB, positioning "foundation models + AI terminals" as its long-term strategy.
