Large model-native AI terminal brand STEPX (Step Terminal) held a keynote event in Shanghai, officially launching its first large model-native intelligent agent phone, STEPX Neo. This model explores a new form of terminal through "hardware + operating system + large model" full-stack deep integration, priced at 3,999 yuan.
Regarding appearance and hardware design, the STEPX Neo adopts a "retro-futuristic aesthetic" design language, with the back panel incorporating a transparent mechanical feel and five Easter eggs paying tribute to the history of AI. On the hardware level, it specially designed unique sensory and expressive organs: a six-microphone array, low-power audio perception chip, and Whisper1.0 sound pickup algorithm form an auditory system; the body is equipped with a dual-screen interactive system consisting of the main screen and an independent MiniLED dot matrix back screen, using the back screen as a dynamic expression space exclusive to the intelligent agent.
In terms of system and model architecture, the STEPX Neo is equipped with the first intelligent agent-native operating system Step AOS 1.0, which integrates long-term memory, task scheduling, and a "trustable, visible, controllable, reversible" security architecture, dividing into "user domain" and "intelligent agent domain" for dual-domain memory. At the brain level, it relies on the Step large model matrix, using a "terminal-cloud collaboration" mechanism: the terminal-side model handles local simple commands and offline operations, while the cloud-side model takes charge of planning complex tasks and cross-application decomposition.
In terms of ecosystem and developer support, STEPX introduced the natural language AI terminal-native development tool Step Studio, and opened up underlying sensor, back screen, and protocol capabilities. The event showcased innovative cases such as a flight skateboard assistance system and a brain-computer interface "thought-to-speech" developed by Bilibili creators using this tool. Meanwhile, the Step Amoo intelligent agent has achieved ecological integration with nearly 100 partners, including Alipay, Tencent (WeChat Work, WeChat Reading, etc.), Xiaohongshu, Ctrip, Didi, Gaode, Meituan, supporting AI payments, A2A cross-intelligent agent collaborative editing, and other full-process service fulfillment.
In terms of business and pricing, the preliminary version of STEPX Neo adopts a "soft and hard model" full-stack pricing, priced at 3,999 yuan (available in carbon black and silicon silver colors), with a gift of 12 months of monthly 10 billion Token usage. Additionally, the first 10,000 users who meet the task criteria will receive "Starship Tickets," granting the right to exchange the current model for a new STEPX terminal at zero cost within the next 5 years. The new device began pre-sales on the evening of October 13th and will be officially available for sale on October 16th.
