Summary
This episode recaps OpenAI Dev Day, highlighting the launch of Dots, a persistent personal agent, and the Decisions API for rapid classification. The show also covers the release of GPT-6.1 Soul, a cost-efficient model, and OpenAI Space, a collaborative workspace for human-agent teams. Additional announcements include plugin extensions, "Sign in with ChatGPT," and a model marketplace for open-source inference.
