**Shanghai, October 13, 2026** — StepFun (阶跃星辰), a leading Chinese AI unicorn, today officially launched the STEPX Neo, the world's first mass-market smartphone designed from the ground up for AI agents. The device was unveiled at the "Ready Builder One" launch event in Shanghai, marking a fundamental shift from app-centric smartphone design to agent-native architecture.

## A New Paradigm: From Apps to Agents

Unlike conventional "AI phones" that bolt AI features onto existing operating systems, the STEPX Neo is built around  **Step AOS 1.0** , the world's first agent-native operating system. StepFun reconstructed the OS framework from scratch, embedding long-term memory, task scheduling, and security mechanisms directly into the system's foundation. The result is a device that autonomously completes complex, multi-step, end-to-end tasks without requiring users to navigate multiple apps or issue repeated prompts.

The phone ships with  **Amoo (阶跃 Amoo)** , StepFun's next-generation personal AI agent. Amoo operates on an  **end-cloud collaborative architecture** : simple commands like setting alarms or adjusting system settings are executed on-device, while complex queries and multi-app orchestration are planned and decomposed by cloud-based models before execution on the device. The system emphasizes a "trustworthy, visible, controllable, and reversible" design philosophy, allowing users to manage permissions, review memories, and monitor task progress.

## Hardware Built for Agentic Interaction

The STEPX Neo features a **dual-screen design** with a distinctive MiniLED dot-matrix rear sub-screen that displays Amoo's operational status, enabling "at-a-glance awareness" of the agent's activities. The industrial design embraces a "retro-futuristic aesthetic," with five hidden design easter eggs on the back panel referencing milestones in AI history — from the number "42" and Turing Test binaries to Transformer architecture motifs.

A standout hardware feature is the  **agentic auditory enhancement system** , comprising a  **six-microphone array** , a low-power audio sensing chip, and the **Whisper 1.0** pickup algorithm. This enables Amoo to accurately recognize user commands even in noisy environments. The dedicated low-power chip runs independently, consuming only **1.2% battery over 24 hours**.
