Kevin Weil is the chief product officer at OpenAI, where he oversees the development of ChatGPT, enterprise products, and the OpenAI API. Prior to OpenAI, Kevin was head of product at Twitter, Instagram, and Planet, and was instrumental in the development of the Libra (later Novi) cryptocurrency project at Facebook.

In this episode, you’ll learn:

1. How OpenAI structures its product teams and maintains agility while developing cutting-edge AI

2. The power of model ensembles—using multiple specialized models together like a company of humans with different skills

3. Why writing effective evals (AI evaluation tests) is becoming a critical skill for product managers

4. The surprisingly enduring value of chat as an interface for AI, despite predictions of its obsolescence

5. How “vibe coding” is changing how companies operate

6. What OpenAI looks for when hiring product managers (hint: high agency and comfort with ambiguity)

7. “Model maximalism” and why today’s AI is the worst you’ll ever use again

8. Practical prompting techniques that improve AI interactions, including example-based prompting
