Bezos-Backed Prometheus Pushes 'Physical AI' to Accelerate Invention

Bezos and Vik Bajaj's Prometheus has raised $12 billion in a new funding round (valued at about $41 billion) to build 'physical AI'—an effort to equip engineers with advanced computational tools to speed up invention, aiming for an 'artificial general engineer' that could drive broad technological breakthroughs. The round includes major institutional backers and Bezos’s own investment, with around 150 employees and a focus on large compute investments; while no specific products are announced yet, Prometheus is positioning itself for a potentially broader $100 billion portfolio fund to back related ventures.
