OpenAI Unveils Developer Platform, Doubles Weekly Users to 4 Million

At OpenAI's recent DevDay, CEO Sam Altman highlighted the explosive growth of ChatGPT, which now boasts 800 million weekly users, and introduced an Apps SDK enabling developers to build applications directly within ChatGPT, effectively transforming it into a platform akin to an app store. This new platform supports integrations with partners like Booking.com, Canva, and Spotify, allowing users to interact with apps through natural language and complete tasks such as bookings and purchases within ChatGPT using the Agentic Commerce Protocol. OpenAI also unveiled enhanced API features, including GPT-5 Pro for high-accuracy industries, a cost-effective voice model "gpt-realtime mini," and the Sora 2 video generation model, extending creative capabilities for developers. The company plans to open app submissions for review and monetization later this year, featuring a directory to highlight high-quality apps, signaling a strategic push to rival traditional app stores like those of Apple and Google. These innovations reflect OpenAI’s commitment to empowering developers with advanced tools while expanding its ecosystem's reach and functionality in an increasingly competitive AI market. Overall, OpenAI is positioning ChatGPT as a central platform for AI-driven applications, aiming to enhance user engagement and developer opportunity across diverse sectors.
