Extreme Harness Engineering for the 1B token/day Dark Factory — Ryan Lopopolo, OpenAI Frontier

Extreme Harness Engineering for the 1B token/day Dark Factory — Ryan Lopopolo, OpenAI Frontier

Ryan Lopopolo of OpenAI's Frontier team discusses "Harness Engineering," a new paradigm where AI agents manage the entire software development lifecycle. He details an experiment building a 1M LOC product with zero human-written code, shifting the engineer's role from coding to designing systems and context for agents. The conversation covers the Symphony orchestration framework, the concept of "agent-legible" software, and the future of AI-driven development.

Peter Steinberger, creator of OpenClaw, discusses his journey into open source, the unexpected success of his AI agent, and how his development workflow has been fundamentally transformed by using agentic AI tools like Codex.

“Engineers are becoming sorcerers” | The future of software development with OpenAI's Sherwin Wu

“Engineers are becoming sorcerers” | The future of software development with OpenAI's Sherwin Wu

Sherwin Wu, head of engineering for OpenAI’s API platform, discusses the radical transformation of software engineering. He shares how 95% of OpenAI engineers use Codex to manage fleets of AI agents, cutting code review times from 15 to 3 minutes. Wu explores the widening productivity gap, the changing role of managers in an AI-first world, and why "models will eat your scaffolding for breakfast", urging developers to build for where AI is going, not where it is today.
