STEPX Neo: The First AI-Native Phone Lands at 3999 Yuan

STEPX Neo: A Phone That Thinks With You, Not Just For You

What if your phone was designed around an AI brain instead of a grid of apps? That's the bet STEPX is making with its first large-model-native intelligent agent phone, the STEPX Neo, launched at a Shanghai event this week. Priced at 3,999 yuan, it's not just another slab—it's a full-stack experiment in what a phone can be when hardware, OS, and large models grow up together.

Design That Nods to the Future (and the Past)

The Neo wears a "retro-futuristic" look, with a transparent mechanical back panel and five Easter eggs that tip a hat to AI history. But the real conversation starters are its sensory organs: a six-microphone array, a low-power audio perception chip, and the Whisper1.0 pickup algorithm that together form an auditory system. Then there's the dual-screen setup—a main display plus an independent MiniLED dot-matrix back screen that acts as the agent's dynamic expression space. Yes, your phone can now give you a look.

An OS Built for Agents, Not Apps

Under the hood runs Step AOS 1.0, the first agent-native operating system. It brings long-term memory, task scheduling, and a security architecture that's "trustable, visible, controllable, and reversible." Memory is split into a "user domain" and an "agent domain," so your personal data stays yours. The brain side relies on the Step large model matrix with a terminal-cloud collaboration: local commands and offline tasks stay on the device, while complex planning and cross-app decomposition head to the cloud.

An Ecosystem That's Already Talking

STEPX isn't going it alone. It introduced Step Studio, a natural-language AI terminal-native development tool, and opened up sensor, back screen, and protocol capabilities. At the event, Bilibili creators showed off a flight skateboard assistance system and a brain-computer interface "thought-to-speech" demo. Meanwhile, the Step Amoo agent has integrated with nearly 100 partners—Alipay, Tencent (WeChat Work, WeChat Reading), Xiaohongshu, Ctrip, Didi, Gaode, Meituan—supporting AI payments and A2A cross-agent collaborative editing. In other words, the services you already use are already on speaking terms with your phone's brain.

Pricing and Availability

The Neo comes in carbon black and silicon silver, and the 3,999 yuan price tag includes 12 months of 10 billion tokens per month. The first 10,000 users who meet the task criteria will receive "Starship Tickets," granting a zero-cost exchange for a new STEPX terminal within five years. Pre-sales started the evening of October 13th, with official sales opening October 16th.
