AI’s third era: the rise of persistent AI coworkers | Tara Seshan (OpenAI’s product lead)

Tara Seshan, head of Codex and ChatGPT Work at OpenAI, on why ambition is now the differentiator, steering vs. rowing, and why you need to build for where the models will be in two to three months

Tara Seshan leads product for Codex and ChatGPT Work at OpenAI (alongside previous podcast guest Andrew Ambrosino, who’s her engineering manager). Before OpenAI, Tara spent over six years at Stripe, where she joined as one of the first five product managers. She went on to lead product for Watershed, which Time magazine named one of the best inventions of 2022, and she is also a founder and Thiel Fellow. Most personally meaningful to me: Tara is one of the three inaugural Lenny’s Newsletter Fellows, a program I ran a couple of years ago to spotlight the most exciting up-and-coming product leaders.

In our in-depth conversation, we discuss:

The shift from “rowing” to “steering,” and why human judgment and ambition will become differentiators as AI takes on execution
How OpenAI thinks about building for model capabilities two to three months out
OpenAI’s best internal memes, such as “Is this maximally accelerated?” and “Are you mainlining it yet?”
Why ambition is the new bottleneck for companies, and why elevating others’ ambitions is now the key part of the PM job
Writing as thinking vs. writing as reporting
