Jeff Bezos says his role as co-founder and co-CEO of AI start-up Prometheus is a "grind," but he still sees the work as fun. It's his first CEO role since 2021.

Prometheus is Jeff Bezos' AI startup that launched in November with $6.2 billion in funding. Vik Bajaj is his co-CEO.

The Amazon founder is serving as the co-CEO of Prometheus, a physical AI startup that just closed a $12 billion round.
