Zuckerberg: Meta is building Prometheus, its first gigawatt-scale AI cluster, at hundreds of billions of dollars

扎克伯格：建千兆瓦级AI集群，集中精英与资本

Zuckerberg stated Meta is building a single AI cluster called Prometheus, exceeding one gigawatt. He used "hundreds of billions of dollars" to describe the capital spend and framed his role as concentrating elite talent, capital, and infrastructure. The post does not disclose a timeline, chip specs, or PUE details—only this one-line claim so far.

Why it matters: Zuck's own post names Prometheus at gigawatt scale with hundreds of billions in capex — an order of magnitude beyond any public project. No timeline, chip spec, or PUE disclosed, so it stays below 85, but as an industry signal it's solid.
