The company unveiled its new Apps SDK, a powerful software development kit that transforms ChatGPT into a universal AI platform. This innovation empowers developers to create commercial mini-applications within ChatGPT, opening new avenues for monetizing AI-driven interactions.

The Apps SDK equips developers with streamlined tools to build, deploy, and monetize AI apps that seamlessly integrate with ChatGPT’s conversational interface.

The valuation milestone underscores OpenAI’s success in positioning itself not just as a pioneer in AI research but also as a dominant commercial platform provider. The combination of breakthrough AI technology and scalable developer tools is accelerating OpenAI’s growth trajectory and influence.

OpenAI’s DevDay announcement signals a new era where AI platforms evolve beyond models into rich developer ecosystems, enabling unprecedented customization, utility, and monetization. For developers and enterprises alike, the Apps SDK opens doors to innovate with AI on a global stage powered by one of the world’s leading AI creators.
