Episode 6 - The future of coding with AI
Summary
OpenAI co-founder Greg Brockman and Codex engineering lead Thibault Sottiaux discuss the journey of Codex from early AI code generation to advanced GPT-5 Codex agents. They highlight the importance of 'harnesses,' agentic coding, and breakthroughs in code review, envisioning AI's profound transformation of software development by 2030. The discussion covers solving novel problems, ensuring security, and the future of compute scarcity.Episode description
What happens when AI becomes a true coding collaborator? OpenAI co-founder Greg Brockman and Codex engineering lead Thibault Sottiaux talk about the evolution of Codex—from the first glimpses of AI writing code, to today’s GPT-5 Codex agents that can work for hours on complex refactorings. They discuss building “harnesses,” the rise of agentic coding, code review breakthroughs, and how AI may transform software development in the years ahead.
