StepFun Launches STEPX Neo AI Phone and Native LLM Terminal Brand

StepFun (阶跃星辰) on July 13 officially unveiled the STEPX Neo AI phone, alongside a new brand dedicated to native large model terminal devices. The launch represents the first instance of a Chinese large model company entering the smartphone hardware space under its own brand, signaling a deepening convergence between AI companies and consumer electronics.

The STEPX Neo is positioned as an "AI phone," integrating the company's large model capabilities directly at the operating system level rather than through pre-installed apps. This native approach aims to deliver seamless AI-powered interactions in everyday use.

StepFun also introduced a new terminal brand to accompany the device launch. The brand's mission is to extend large model capabilities from the cloud to edge devices, enabling users to experience AI-driven interactions without relying solely on cloud connectivity.

This move distinguishes StepFun from traditional smartphone makers like Honor and OPPO, as well as internet-phone brands like Xiaomi. Previously, AI companies entered the mobile market primarily through software partnerships — co-developing on-device models with handset makers rather than selling their own hardware.

Technically, the STEPX Neo likely employs on-device inference, running smaller models locally on flagship mobile chips to reduce latency and protect user privacy. The current industry standard places models under 7B parameters on high-end mobile processors.

StepFun's foray into AI hardware reflects broader efforts among Chinese LLM companies to explore direct monetization channels beyond API calls and model licensing. A自有-brand device offers a more direct revenue stream and fuller control over the user experience.

Key questions going forward include the STEPX Neo's specifications, pricing strategy, and how its integrated AI functions will differ from those already available on mainstream smartphones. A positive market reception could pave the way for more AI-native terminal devices from other model companies.
