Step Terminal officially launched its first 'Agent Phone,' the STEPX Neo Pioneer Edition, featuring the agent-native operating system Step AOS and personal agent Step Amoo, priced at 3999 yuan with a bundled Token Plan. Beyond model capabilities, this launch is really betting on whether a system-level security foundation and developer tools can get an agent ecosystem running.
Step Terminal officially launched its first 'Agent Phone,' the STEPX Neo Pioneer Edition, featuring the agent-native operating system Step AOS and built-in personal agent Step Amoo (which the author calls A-Zai). From an interaction design perspective, the STEPX Neo has dual entry points: swipe right to enter Amoo's dedicated system-level space, swipe left to return to the familiar phone home screen. A collapsible panel is permanently docked at the bottom of the screen; tapping it opens a system-level Agent task navigation bar, where users can view long-chain tasks A-Zai is advancing in the background and their history.
On the hardware side, the STEPX Neo has a small screen at the upper right of its back as the working status area for Step Amoo, displaying states such as thinking, Tool Call, and output; an AI button on the side summons an input box with a light press and directly activates voice intercom with a long press. These designs point to the same judgment: the Agent is no longer an app that needs to be opened, but a permanently on-call role placed into the system layer.
What supports this role is Step AOS's system-level capabilities—support for Loop cyclic execution, autonomous Tool Call, and the ability to invoke various Skills and MCP tools. The author says that after receiving the prototype for half a month, they used it almost as their primary device during the National Day holiday, and calls it a 'physical version of an Agent.' It should be noted that the above experience description comes from a single-source author's self-report, belongs to source_claim, and has no third-party independent verification yet.
The STEPX Neo is priced at 3999 yuan, sold as a full-stack software-hardware bundle. Buyers of the STEPX Neo Pioneer Edition can enjoy a STEPX Token Plan with 10 billion tokens per month for 12 consecutive months. This bundling means that what users pay for is not only the hardware cost, but also a period of model invocation quota.
At the same time, Step Terminal introduced the 'Step Amoo Growth Plan': the first 10,000 users who meet task criteria will receive a 'Starship Ticket,' and within the next five years can exchange their STEPX Neo for any new STEPX terminal at zero cost. This plan binds early users' long-term retention with subsequent device upgrades.
However, the specific rules of the Token Plan and Growth Plan have not yet been disclosed: the billing basis and validity details for the 10 billion tokens per month are not explained, and the criteria for 'meeting task criteria' are not defined in the article. These all belong to source_claim, and readers need to retain uncertainty when evaluating actual value.
Step Terminal launched Step Studio on the device side, an AI terminal-native development tool that provides a software workspace for writing, testing, and managing code. Developers can write SKILL.MD to connect Agents, external APIs, and phone system capabilities. In the article, the author describes their own process of using Step Studio to create a vertical information feed app and push it to a real device for testing, saying the preview matched the real-device result.
On ecosystem connection, Step Terminal connects with third-party ecosystems through multiple agent connection protocols such as A2A and MCP, and proposed the H2A2A (Human to Host Agent to Service Agent) model, in which users express needs to Step Amoo, and Step Amoo then invokes professional service agents to complete tasks. This model attempts to open external service capabilities to terminal scheduling.
But the degree of openness remains to be seen: the extent of Step Studio and Step AOS's openness to third-party developers and their review processes are not detailed, and the actual service providers and covered scenarios for the H2A2A protocol are not listed in the article. These gaps determine whether the ecosystem can move from demonstration to scale.
The higher the permissions, the more concrete the risk of losing control. Step Terminal built a 'trustworthy, visible, controllable, reversible' security foundation in Step AOS: all data uploaded to the cloud is desensitized, and phone numbers, precise locations, and sensitive multimodal images will not be recklessly used without limits; all tool calls, permission requests, and execution chains are fully logged; at high-risk nodes such as deletion, payment, and cross-app operations, a pop-up must trigger the user's secondary confirmation, and authorization boundaries can be revoked with one click at any time; photos, files, notes, or contacts mistakenly deleted by the agent can be restored step by step or as a whole by the system. A separate 'Agent Security' module is listed in system settings, where A-Zai's permissions can be managed and visualized Tool Call records can be viewed.
Thresholds are also set on the ecosystem side: Step Terminal requires all publishers to complete real-name verification consistent with their phone number, all Skills and Agents must be under real-name registration, and it will block uploads of privacy files including .env, key files, databases, logs, or USER.md.
These mechanisms are currently all self-reported by Step Terminal or the author, lacking third-party verification. The actual effect of the 'trustworthy, visible, controllable, reversible' security foundation lacks independent evaluation support, and actual test data or vulnerability audit results for the security mechanisms have not been disclosed. In personal agent scenarios, users' willingness to entrust is a key variable for scaling, and this variable precisely depends on externally verifiable security evidence.
This article is a single-source report by QbitAI, with no other independent sources provided for cross-verification. The actual mass production and shipping time of the STEPX Neo Pioneer Edition is not specified in the article, nor does the article disclose the STEPX Neo's specific hardware specifications, chip model, or performance benchmarks, nor the version number, release timeline, or compatible device range of Step AOS, nor the specific list of third-party service providers connected to Step Amoo.
Therefore, judgments about the STEPX Neo should be layered: the product launch, operating system installation, built-in personal agent, and 3999 yuan pricing are confirmed facts; the Token Plan, Growth Plan, dual entry points, Loop and Tool Call, back-screen status area, AI button, task navigation bar, Step Studio, H2A2A, security foundation, and real-name registration all belong to source_claim, coming from Step Terminal or the author's self-report.
From the disclosed information, the path Step Terminal has chosen is software-hardware-model integration: using a system-level security foundation to exchange for room for ecosystem openness, using Step Studio to lower the threshold for makers, and then using the Token Plan and Growth Plan to bind early users. Whether this path can hold depends on undisclosed mass production pace, developer openness rules, and independent verification results for the security mechanisms.
All information in this article comes from a single-source report by QbitAI, with no other independent sources provided for cross-verification. Among these, the STEPX Neo launch, installation of Step AOS, built-in Step Amoo, and 3999 yuan pricing are confirmed facts; the Token Plan, Growth Plan, dual entry points, Loop and Tool Call, back-screen status area, AI button, task navigation bar, Step Studio, H2A2A, security foundation, and real-name registration are all self-reported by Step Terminal or the author, belonging to source_claim and lacking third-party verification. The article does not disclose hardware specifications, chip model, performance benchmarks, Step AOS version number and release timeline, compatible device range, third-party service provider list, or actual test data or vulnerability audit results for the security mechanisms. The actual mass production and shipping time of the STEPX Neo Pioneer Edition, the billing basis and validity details for the 10 billion tokens per month, the criteria for 'meeting task criteria,' the extent of Step Studio and Step AOS's openness to third-party developers and their review processes, and the actual service providers and covered scenarios for the H2A2A protocol are all not specified in the article.
The STEPX Neo elevates the Agent from an app to a system native, and uses 3999 yuan to bundle the Token Plan, Step Studio, and security foundation to build an ecosystem. But aside from the launch, system installation, built-in agent, and pricing, the other key mechanisms all come from single-source self-reports; mass production pace, developer openness rules, and independent verification of the security mechanisms remain the core variables determining whether this path can hold.
