Sam Altman unveils OpenAI's ambition to build an "AI Operating System" at DevDay 2025. The keynote's four core announcements—the Apps SDK for native ChatGPT applications, the Agent Kit for accelerating agent deployment, the official launch of Codex (powered by GPT-5) as a software engineering agent, and the Sora 2 API preview—collectively outline a new paradigm for software development. For developers, this is more than a tooling update; it is a practical demonstration of a future where software creation takes minutes rather than months, making it essential viewing to understand the next generation of the AI ecosystem.
