Jeff Bezos’s AI venture has added a hire from Elon Musk’s xAI. Kyle Kosic, who built the infrastructure for xAI’s Colossus supercomputer and briefly returned to OpenAI, is joining the effort known internally as Project Prometheus. The move underscores the startup’s talent push as it targets industrial‑grade AI. His recruitment follows a wave of departures from Musk’s xAI, where all eleven co‑founders have now left.

Prometheus, co‑led by Bezos and former Google executive Vikram Bajaj, has already staffed hundreds across San Francisco, London and Zurich, focusing on engineers and researchers capable of building massive infrastructure. The firm aims to create AI that understands physics and can be trained on domain‑specific data such as jet‑engine design, claiming it has assembled the largest engineering data corpus to date.

The venture is courting sovereign wealth funds from Singapore and the Gulf to raise tens of billions for a permanent‑capital vehicle that will take equity stakes in engineering, aviation and design firms, effectively embedding forward‑deployed engineers within them. By securing both data and influence, Prometheus hopes to accelerate AI‑driven efficiency gains, a strategy that could reshape valuation metrics for heavy‑industry players.
