StepFun Unveils Agentic Phone Solution
APPSO · wechat · 2026-07-13
StepFun has launched a comprehensive agentic terminal solution, featuring the AI hardware brand STEPX, the agent-native OS StepAS, and the primary agent Amoo. The core focus isn't on hardware specs, but rather exploring whether traditional app-centric operating systems can handle the transition of AI from simply "answering" to actually "acting."
StepAS is designed as a combination of a "model matrix + agent-native OS." Models handle perception, memory, and planning, while the system connects services, allocates resources, and executes tasks. It supports protocols like MCP, A2A, and CLI, with GUI as a fallback. The system emphasizes dynamic routing across on-device, cloud, and hybrid paths based on task requirements. It also introduces a security governance framework that is "trusted, manageable, visible, and reversible," supporting operation auditing, tracing, and rollback.
Commercially, StepFun positions STEPX beyond mere hardware sales or pre-installation/ad revenue sharing. Instead, it aims to explore new business models like hardware, system licensing, model API calls, and subscriptions. The article frankly notes that this path ultimately depends on product validation: whether agentic phones are genuinely more effective than bolting an AI assistant onto an old OS, and if users are willing to delegate more action permissions to it.
