STEPX Neo hands-on: dual-domain memory, intent-as-a-service and a maker ecosystem

新智元 · wechat · 2026-10-13

A deep dive into STEPX Neo, the newly launched LLM-native agentic phone from STEP/StepFun, framing it as designed backwards from what an agent needs rather than bolting AI onto a phone.

Hardware: a six-mic array with Whisper 1.0 and a low-power audio chip for hearing, a rear MiniLED display showing Amoo's six working states, and a dedicated AI key. StepAOS implements a dual-domain layered memory system — user preferences in one domain, agent's accumulated task experience in the other — continuously consolidated via record, reason, recall, unlike assistants that reset each session.

Amoo connects to nearly 100 partners (Alipay, Tencent, Ctrip, Didi) via the H2A2A protocol to complete multi-app tasks like booking and paying. Safety rests on verifiable, visible, controllable, reversible actions. For makers, StepStudio enables conversational creation of Skills and Agents across model, system, hardware and ecosystem layers; demos include a flying skateboard and a social-icebreaker skill. Price: 3,999 yuan bundled with 10B tokens/month for a year, plus a free-upgrade ticket for the first 10,000 qualifying buyers.
