OpenAI’s Head of ChatGPT: We’re entering a new era of AI (again) | Tibo Sottiaux

Oct 4, 2026 · 37:23

Lenny's Podcast interviews Tibo Sottiaux, OpenAI's Head of ChatGPT and Codex, who argues always-on agents like OpenAI's new Dots will replace today's apps since most actions on the internet will soon be taken by agents. He explains Dots works 24/7 across devices with no model picker, that Codex and ChatGPT Work will merge for ChatGPT's 1.2 billion users, and that agent loops and graphs are a passing phase versus systems that learn. He details the open ecosystem—Sign in with ChatGPT at 16 partners, plugin revenue share—where plugin discovery runs on retention, not SEO. His Dot warned him five minutes before a DevDay demo that production was down; he says typing fast matters less while taste and 120+ ex-founders define hiring. He cites OpenAI's safety spend and the withheld 6.1 Astra model.

Chatbots are not the final interface: OpenAI’s Head of Design on what’s next | Ian Silber

Ian Silber, head of product design at OpenAI, tells Lenny that designers' anxiety about AI comes from unclear expectations and a design process that still takes time even as engineers 10x, but insists this is the best time in history to be a designer because AI is already an incredible designer and anyone can make ideas real in minutes. He explains OpenAI hires for curiosity, prototyping and systems thinking rather than AI backgrounds, and steers designers to "just do less" by reusing systems and focusing on durable experiences. He defends the chat interface as the right way to span a wide spectrum of intelligence, and shares that ChatGPT's future involves proactivity, voice, and one universal input that works for novices and power users alike. He credits failure at Instagram with IGTV before Reels, and urges struggling designers to embrace exploration and focus on outcomes rather than process.
