Good morning. Switching things up today in celebration of our fifth annual Fortune Brainstorm AI, which continues today in San Francisco.

We kick things off with OpenAI COO Brad Lightcap and close out the day with Rivian CEO RJ Scaringe. (See the agenda here; watch here.)

Below, three highlights from Day 1 of our gathering, plus the day’s tech news in “More tech.” —Andrew Nusca
