OpenAI unveiled a new software development kit (SDK) at its annual developer conference, allowing third-party applications to be embedded directly into ChatGPT. CEO Sam Altman emphasized that this innovation will foster a new generation of adaptive and interactive applications. Initial demonstrations featured apps from Spotify, Canva, and Zillow, showcasing functionalities such as creating business pitches and displaying real estate listings. The SDK is currently available to select developers, with plans for broader access and monetization options in the future. OpenAI aims to position ChatGPT as a central hub for user interactions, merging web and mobile experiences into a chat-driven operating system. This move follows previous attempts to integrate custom widgets, which did not gain significant traction. The company is also enhancing its coding tools and competing with other tech giants to attract developers, amidst a growing landscape of open-source AI models.
