Core Viewpoint - The article argues that the notion of "AI Browser = OS" is fundamentally flawed, emphasizing that while AI browsers may exhibit functionalities similar to operating systems, they do not possess the core responsibilities and capabilities that define an OS [6][9][23]. Group 1: AI Browsers and Their Capabilities - AI browsers like Dia, Comet, and ChatGPT Atlas are emerging as significant players in the AI landscape, with traditional browsers like Chrome and Edge also adopting AI features [3][7]. - The capabilities of AI browsers have expanded to include functionalities that were traditionally associated with operating systems, such as PWA, Service Worker, and background synchronization [7][9]. - Despite these advancements, AI browsers lack essential OS functions such as process scheduling, memory management, and system calls, which are critical for true operating system classification [9][11][15]. Group 2: Definition and Future of AI Browsers - The article suggests that a more appropriate term for the operational layer of AI browsers would be "Agent Operating Layer" (AOL), which focuses on orchestration, permissions, and state management [16][23]. - Future developments may lead to a "universal container" model for AI browsers, allowing for better integration with various AI models and APIs, thus enhancing their functionality [18][22]. - The shift from a model-centric approach to a capability-centric approach is anticipated, where the focus will be on defining stable and governable capabilities rather than merely upgrading models [22][23].
