ChatGPT, once primarily a conversational AI, has undergone a profound transformation in 2025, evolving into a multifaceted "everything app" and even aspiring to be an AI-native operating system. This strategic pivot by OpenAI has integrated an extensive array of functionalities, from real-time multimodal interaction to seamless third-party application integration and autonomous agentic capabilities, fundamentally reshaping how users interact with technology and conduct daily tasks. ### The Rise of Multimodal and Agentic Intelligence A cornerstone of ChatGPT's evolution is its advanced multimodal capabilities, spearheaded by models like GPT-4o and the highly anticipated GPT-5. By mid-2025, ChatGPT could process and generate responses across text, voice, and vision in real-time. The May 2025 update to the ChatGPT app introduced real-time voice conversations and image recognition, allowing users to speak directly with the AI and upload images for analysis, such as summarizing whiteboard notes or explaining textbook pages^[1][2]. The upcoming GPT-5, slated for public release in summer 2025, is described as the first truly unified model, capable of handling text, voice, vision, code, and even web navigation within a single conversational system, autonomously understanding context and selecting the appropriate mode^[3][4]. Beyond mere interaction, ChatGPT is now embracing agentic intelligence, moving from a reactive chatbot to an AI agent capable of executing multi-step processes with minimal user input^[5][6]. OpenAI's AgentKit, a new toolkit, facilitates the development of these autonomous AI agents, enabling ChatGPT to perform complex tasks like booking meetings, filling out forms, or interacting with external web applications independently^[7]. * **GPT-4o (Omni):** Introduced in May 2024, this model enables native multimodal interaction across text, audio, and vision, offering more fluid inputs and outputs^[2][8]. * **Real-time Voice and Vision:** The ChatGPT app, updated in May 2025, allows users to engage in natural voice conversations and upload images for analysis, with the ability to stream video from a smartphone's camera for live interpretation and guidance^[1][9][10]. * **Agentic Capabilities:** By late 2024 and throughout 2025, OpenAI has focused on developing AI agents that can perform multi-step tasks autonomously, with CEO Sam Altman stating that "2025 is when agents will work"^[5][6]. ### A Platform for Integrated Applications and Enterprise Power OpenAI's DevDay 2025, held on October 6 in San Francisco, marked a pivotal announcement: the introduction of the ChatGPT Apps SDK^[11][7][12]. This initiative fundamentally transforms ChatGPT from a conversational AI into a comprehensive application platform, akin to an "app store woven into an AI assistant"^[11]. Users can now invoke and interact with various third-party applications directly within the ChatGPT interface, eliminating the need to switch between different programs^[11][7][13]. Launch partners for the Apps SDK include major services such as Spotify, Canva, Zillow, Figma, Coursera, Expedia, and Booking.com, with Uber, DoorDash, OpenTable, and Target expected to join soon^{[11][14][7][15]}. This integration allows users to perform tasks like creating playlists, designing graphics, searching for homes, or booking travel, all through natural language commands within ChatGPT^[11][7]. OpenAI is also establishing an App Directory to help users discover and monetize these integrated applications^[14][7]. For businesses, ChatGPT Enterprise has emerged as a transformative tool. By June 2025, OpenAI reported 3 million paying business customers across its Enterprise, Team, and Edu plans, a 50% increase from February^[16]. ChatGPT Enterprise offers: * **Uncapped GPT-4 Access:** Removes usage caps, providing unlimited conversational queries^[17]. * **Extended Context Window:** A substantial 32,000-token context window allows for longer, more detailed queries and nuanced responses, a four-fold increase over the standard GPT-4 model^[17]. * **Faster Performance:** Delivers responses up to two times faster than the regular model^[17]. * **Enhanced Security and Integrations:** Offers GDPR-compliant isolated instances, role-based access controls, and connectors that bridge internal knowledge sources like Google Drive, OneDrive, and SharePoint with the ChatGPT platform^[16][18]. ### The Vision of an AI Operating System OpenAI's long-term vision positions ChatGPT not just as a powerful application, but as an "AI-native operating system"^{[11][19][12][13]}. This approach aims to create a chat-driven environment where users can accomplish nearly any task without leaving the ChatGPT interface, effectively becoming a central gateway for digital services^[11][13]. Nick Turley, head of ChatGPT, stated in October 2025 that the evolution would see ChatGPT transform "from an app that is really useful into something that feels a little bit more like an operating system," where users can access both existing and newly built software natively on top of ChatGPT^[14][15]. The company's strategy involves controlling the interface layer, leveraging its massive user base—which reached 800 million weekly users by October 2025—to attract developers to its platform. Fu^[11][12][15]rthermore, OpenAI is exploring monetization strategies, including revenue-sharing deals and an "Agentic Commerce Protocol" co-developed with Stripe, allowing for instant checkouts directly within ChatGPT, filling a crucial gap in the AI application landscape. T^[11][14][13]he introduction of a desktop app for Mac and Windows further solidifies this operating system ambition, providing system-level AI capabilities like global keyboard shortcuts, integrated voice chat, and screenshot/file analysis. Wi^[4]th its continuous advancements in multimodality, platform integrations, and agentic intelligence, ChatGPT is rapidly cementing its role as an indispensable "everything app," fundamentally altering the digital landscape and user expectations for AI interaction.
