Recorded live at OpenAI's DevDay, hours after a launch of more than twenty products, Lenny talks with Tibo Sottiaux, who leads ChatGPT and Codex. The centerpiece is Dots, a personal agent that runs around the clock, learns your goals and preferences, works across channels like text, email and meetings, and has no model picker. Users currently get one primary Dot, with multiple role-specific Dots coming soon. Tibo argues that hand-tuning agent loops and graphs is a passing phase that will give way to systems that simply learn. He also says Chat and Work modes will merge, and that Dots' capabilities will eventually ship to ChatGPT's roughly one point two billion users. Tibo calls the open ecosystem the launch's 'sleeper hit.' It includes sign-in with ChatGPT for partner tools, plugin discovery, and a revenue share for popular plugins. Plugins are recommended based on retention and quality rather than marketing. His biggest 'not priced in' claim is that most actions on the internet will be taken by agents, while models get dramatically cheaper and faster and modalities merge. His advice to builders is to imagine everything ten times better within a year and to design for agent-scale traffic. On people and work, the skills gaining value are taste, user empathy and a founder mindset. OpenAI has more than 120 ex-founders. Roles are blurring, and new grads who learn fast and go all in on AI have an edge. Tibo addresses loneliness and pressure to do more, and argues AI should reduce noise rather than add 'one more prompt per second.' On safety, he points to heavy investment in secondary monitoring and to withholding a more capable model. His biggest frustration is complexity: users shouldn't need 'a PhD in model pickers.'
