Alexandr Wang, who now leads Meta's AI efforts, says he sent Mark Zuckerberg a lengthy memo just days before accepting the job. Its main point: a small group of top talent matters more than a big workforce.
He shared those details on the Cheeky Pint podcast, with Zuckerberg as a guest. Zuckerberg said the second idea was being ready to start over, and admitted he was unhappy with Llama 4.
Wang puts Meta's core AI research team at closer to 100 people. Its latest model, Muse Wonder, is out now, and Wang says it performs best on his team's agent tests.
