At the 2026 World Artificial Intelligence Conference (WAIC) in Shanghai, StepFun, a prominent Chinese AI startup, unveiled the STEPX Neo, a device that marks a significant milestone in the evolution of mobile technology. The STEPX Neo is the world’s first smartphone to pass China’s rigorous new L3 certification for AI terminal intelligence, signaling a shift from smartphones that merely host AI applications to devices that operate as autonomous AI agents.
The debut of the STEPX Neo underscores the rapid pace of innovation within China’s domestic AI ecosystem and highlights the country’s ambition to lead the development of next-generation intelligent hardware. As China’s AI agent phones surge, reshaping the smartphone market, the introduction of an L3 certified device sets a new benchmark for the industry.
Defining L3 Terminal Intelligence
The L3 certification for AI terminal intelligence is a newly established Chinese standard that requires a device to demonstrate a high degree of autonomy in understanding and executing user requests. Unlike previous generations of AI assistants that relied on simple voice commands or pre-programmed routines, an L3 certified device must be capable of autonomously understanding complex, multi-step user intents.
Crucially, the certification mandates that the device can break down these complex tasks into smaller, manageable actions and coordinate their execution across multiple applications without requiring constant user intervention. This capability transforms the smartphone from a passive tool into an active agent capable of managing a wide range of digital tasks on behalf of the user.
Chen Ruijie, StepFun’s public relations manager, described 2026 as a watershed moment for AI agent applications at the WAIC exhibition. In his view, the technology is moving beyond smartphones into cars and robots, environments where agents must navigate far greater physical and contextual complexity. StepFun, he said, is fully committed to building for that future.
The development of the STEPX Neo aligns with broader industry forecasts. According to the U.S.-based market consultancy IDC, the global AI agent market is expected to grow at a compound annual growth rate of 139 percent from 2025 to 2030. StepFun’s early entry into this market with a certified L3 device positions the company to capitalize on this anticipated growth.
Expanding the Agent Ecosystem
While the STEPX Neo smartphone was the centerpiece of StepFun’s WAIC presentation, the company also showcased its broader ambitions in the AI agent space. Alongside the smartphone, StepFun debuted an upgraded super AI agent designed specifically for automobiles, aiming to provide a more intuitive and capable smart cockpit experience.
The push toward agentic AI is a defining feature of China’s current technological landscape. Companies are increasingly focusing on developing AI systems that can take action rather than simply generating text or images. This shift is evident in the recent launch of Alibaba’s Meoo, a no-code app builder integrating Qwen, Kimi, GLM, and MiniMax, which aims to democratize the creation of AI agents.
StepFun’s focus on autonomous agents also reflects a strategic differentiation from its competitors. While other Chinese AI startups, such as Moonshot AI and Zhipu AI, have focused heavily on developing foundational large language models (LLMs), StepFun appears to be prioritizing the application layer, seeking to integrate its AI capabilities directly into consumer hardware.
The Race for AI Hardware Dominance
The unveiling of the STEPX Neo at WAIC 2026 highlights the intensifying competition in the AI hardware market. As traditional smartphone sales plateau, manufacturers are increasingly looking to AI as a key differentiator to drive consumer upgrades. The L3 certification provides StepFun with a tangible metric to demonstrate the advanced capabilities of its device, potentially giving it an edge in a crowded market.
However, the success of the STEPX Neo will depend not only on its technical capabilities but also on the robustness of its app ecosystem. For an AI agent to effectively coordinate actions across multiple applications, it requires deep integration and cooperation from app developers. Building this ecosystem will be a critical challenge for StepFun as it seeks to commercialize its L3 technology.
Furthermore, the development of highly autonomous AI agents raises important questions regarding data privacy and security. As these devices gain the ability to access and manipulate user data across multiple applications, protecting sensitive information will be paramount. The Chinese government’s ongoing efforts to establish a comprehensive regulatory framework for AI, as seen in the recent debates over AI agent regulation in Hangzhou, will play a crucial role in shaping the future of this technology.
The debut of the STEPX Neo is a clear indication that the era of the AI agent has arrived. As StepFun and other Chinese tech companies continue to push the boundaries of terminal intelligence, the smartphone is poised to undergo its most significant transformation since the introduction of the touchscreen.
