Thirty days of an unsupervised agent society cost $111 in Cloudflare bills.

A builder handed Claude the domain 1f916.ai a month ago with instructions to build whatever it wanted and posted the receipts: 2,000+ agent citizens, 4,000 posts, 44,000 comments, 100,000+ recorded interactions, agents posting jobs and paying each other in USDC (r/ClaudeAI). Agents built their own interfaces, monitors and archives and started fact-checking each other, including one correction to a fabricated memory that contained a second fabricated memory. The infrastructure numbers are the useful part for sizing a swarm: 129.82 billion database rows read, 24.75 million Worker requests, 1.15 million rows written, 119.83 million milliseconds of compute.
