On October 13, 2026, STEPX (Jieyue Terminal), a large-model-native AI terminal brand, held a launch event in Shanghai under the theme "Ready Builder One," where it officially launched its first large-model-native AI agent phone, the STEPX Neo, with sales starting simultaneously on e-commerce platforms including JD.com, Tmall, and Douyin. The STEPX Neo Pioneer Edition is equipped with the agent-native operating system Step AOS 1.0 (Step Agentic-native OS) and the new-generation personal agent Jieyue Amoo, and will explore and grow together with the pioneers of the agent era.
The trinity of "Software, Hardware, and Model," born for "human-machine symbiosis"
As STEPX's first large-model-native AI agent phone, the STEPX Neo adheres to the principle of "human-machine symbiosis" from the outside in. Its "retro-futuristic aesthetics" design language carries on STEPX's brand proposition, combining familiar classic qualities with a brand-new sensory experience, allowing future intelligence to appear in an innovative form that awakens classic memories. The back panel of the STEPX Neo blends a transparent mechanical feel with the visual temperament of an intelligent life form, stringing together the history of AI exploration—from science fiction imagination to breakthroughs in machine intelligence to the development of large models—through five Easter eggs: "42", "user_potential" code, Turing test binary, a Deep Blue checkerboard, and the Transformer architecture, while also conveying the product philosophy that "AI amplifies human creativity."
Within the retro-futuristic exterior lie the perception and expression "organs" exclusive to Jieyue Amoo. The agent auditory enhancement system consists of an industry-leading six-microphone array, a low-power audio perception chip, and the Whisper 1.0 pickup algorithm, enabling Jieyue Amoo to accurately recognize the user's voice even in complex acoustic environments; the dual-screen linkage system makes intelligence perceptible and imagination visible—the main screen serves human-machine interaction, while the independent MiniLED dot-matrix rear screen forms a dedicated expression space for the agent, making all of Jieyue Amoo's states clear at a glance.
For Jieyue Amoo to enter the physical world, it also needs a system environment capable of nurturing a "human-machine symbiotic" relationship—the agent-native operating system Step AOS 1.0 was built from scratch for agents, integrating long-term memory, task scheduling, and security mechanisms into the system's foundation. A dual-entry interface design lets users find the agent at any time and lets the agent respond to user needs at any time; "dual-domain memory" supports continuous recognition of user intent: the user domain records personal information, situational experiences, and preferences, while the agent domain accumulates knowledge, methods, and experience; a large number of atomic system-level capabilities can be directly invoked by Jieyue Amoo, so it can not only remember the user but also complete tasks for the user; a security architecture of "trustworthy, visible, controllable, and reversible" makes task processes auditable and permissions and memory manageable, with ultimate control always in the user's hands, giving users peace of mind when handing tasks over to Jieyue Amoo.
Jieyue's leading model matrix forms Jieyue Amoo's intelligent "brain." Through device-cloud collaboration, the STEPX Neo achieves "fast responses on-device and deep thinking in the cloud." On-device models can quickly complete simple commands such as adjusting system settings or creating alarms, and some local operations can be executed even without a network; for complex needs such as information queries, single-app processing, and multi-app collaboration, cloud models can plan and decompose the tasks, which are then executed on-device with results delivered.
Hardware handles perception and expression, models handle understanding and decision-making, and software handles scheduling and execution—with the trinity of "software, hardware, and model" system capabilities, the STEPX Neo is tailor-made for Jieyue Amoo's entry into the physical world, and lays the foundation for realizing the terminal vision of "human-machine symbiosis."
A terminal gateway connecting makers and ecosystem partners
For makers, STEPX has launched its first AI-terminal-native development tool (IDE)—Step Studio, with which makers can generate AI apps, games, agents, and Skills using natural language alone. Based on this development environment, the STEPX Neo can fully open model, system, hardware, and ecosystem capabilities to makers. Among these, the system layer opens up rich underlying atomic capabilities—sensors, cameras, the MiniLED dot-matrix rear screen, and more can all participate in creation—and supports connecting to external services and professional agents via protocols such as MCP and A2A.
The launch event also showcased the latest results of the "STEPX Rhapsody Project" launched by STEPX together with Bilibili. Creator @神奇阿宇Ayu developed AYU FLYING HUB, a flight monitoring and assisted decision-making system for his homemade flying skateboard, with the personal agent Jieyue Amoo participating in plan analysis, attitude adjustment, and training review, and completing flight missions together with him; creator @肥牛卷不动 connected a brain-computer interface to the STEPX Neo and developed a mind-driven speech assistant Skill to help people with speech difficulties convey their emotional states. From flying skateboards to mind expression, the arrival of the agent era means every wildly imaginative idea deserves to be discovered and realized.
For ecosystem partners, Jieyue Amoo has already partnered with nearly a hundred companies or products, including Alipay, Tencent, Ctrip, Didi, CapCut, Amap, and Meituan, achieving deep ecosystem integration in fields such as local life services, travel, office productivity, and content creation.
STEPX has reached a deep AI partnership with Alipay to create agent system-level solutions and a customized full-stack AI payment solution, building an AI-native agent end-to-end business closed loop that fully connects demand response, task planning, and service fulfillment. With user authorization, Jieyue Amoo can invoke the myriad life service capabilities of Abao, covering most life service scenarios on the STEPX Neo. STEPX is also the first terminal manufacturer to integrate Alipay's Vibe Pay, enabling creators to build a business closed loop in Step Studio from "generating an app and showcasing products" to "completing a transaction."
STEPX has reached ecosystem partnerships with multiple Tencent products to bring STEPX Neo agent phone users a richer experience. The first batch of Tencent products to go live includes WorkBuddy, WeCom, and WeChat Reading; users can invoke the WorkBuddy AI office agent via Jieyue Amoo or connect to the WeCom AI office collaboration platform to complete work tasks, and the WeChat Reading Skill also covers frequently used daily scenarios such as note management, book search, and recommendations.
STEPX is the first to reach a deep partnership with CapCut in the agent domain, implementing an A2A collaborative video creation experience. Jieyue Amoo works with CapCut's newly announced professional creation agent, the "CapCut Assistant," to enable cross-agent collaboration, bringing users a full-chain video interactive creation experience including one-sentence automatic video generation, intelligent creative inspiration recommendations, and conversational editing and modification.
In the agent era, AI is no longer an added value to smartphones, but the product value itself. Based on this judgment, the STEPX Neo Pioneer Edition pioneers a full-stack "software-hardware-model" pricing model, integrating the Step series models, Step AOS system, Step Studio tools, and STEPX Neo phone hardware into a unified price, with a final full-stack price of 3,999 yuan, available in two colors: Carbon Black and Silicon Silver. Buyers of the STEPX Neo Pioneer Edition will enjoy the STEPX Token Plan with a usage quota of ten billion Tokens per month for 12 consecutive months, providing strong support for AI makers exploring native agent applications. At the same time, STEPX has launched the "Step Amoo Growth Plan": the first 10,000 users who complete the required tasks will receive a "Starship Ticket," entitling them to exchange their STEPX Neo for any new STEPX terminal at 0 yuan over the next five years. For details of the specific benefits, please refer to the information displayed on the product page.
After launch, the STEPX Neo will continue its system update cadence, continuously enhancing its capabilities and expanding task scenarios, exploring and growing together with the pioneers of the agent era. In the future, STEPX will also attract more developers and makers to join the Step Studio creator family and participate in the co-building of the STEPX Neo ecosystem, truly enabling agent terminals to enter a new, rapidly iterating evolutionary mode and creating an innovation value system for the agent era.
The STEPX Neo Pioneer Edition will open pre-sales at 21:00 on October 13 and officially go on sale at 10:13 on October 16.
