On July 13, StepFun’s chairman and terminal head Yin Qi officially unveiled STEPX, a native AI terminal brand built entirely on large models. Alongside the brand, they also introduced their first product: a large-model-native “Agentic Phone,” which runs on the agent-native Step AOS system and comes pre-loaded with the StepFun Amoo AI agent.
This launch marks a bold step into a future where our devices aren’t just smart—they actually understand what we need. Imagine a phone that learns your habits, remembers your preferences, and proactively helps you get things done, all without you having to tap through endless menus. That’s the kind of experience STEPX is aiming for.
The Agentic Phone feels less like a traditional smartphone and more like having a personal assistant that’s always with you, ready to jump in and handle tasks—from scheduling to information searching—just by chatting naturally.
