Meta CEO Mark Zuckerberg has been on something of a hiring spree lately, trying to staff up Meta’s new superintelligence team with top-tier AI researchers from competing labs. To work on a team led by former Scale AI CEO Alexandr Wang and at a desk physically near Zuckerberg, Meta has reportedly offered employees from OpenAI and Google DeepMind compensation packages worth upwards of $100 million.

OpenAI CEO Sam Altman confirmed those reports on a podcast with his brother, Jack Altman, which was published on Tuesday. However, the OpenAI CEO noted that Zuckerberg’s recruiting efforts have been largely unsuccessful and made sure to throw a few more digs at Meta in the process.
