Coding agents broke OpenAI's Git. Codex sped up their engineers so much that by the end of last year the monorepo couldn't keep up. Slow pushes, failed merges, and reliability at times below 90%. The work multiplies. One engineer now has several changes heading to CI at once, and every push sets off more jobs fetching the same code. So they built a new Git backend called Pando. It went from kick-off to production in 10 weeks, designed by one engineer and written by teams of agents. Median push latency is down nearly 80%, and it now serves close to a petabyte of Git data a day. This is what agents do to infrastructure. Every agent is another worker pushing code, running tests and pulling data, and all of that lands on storage, networks and CPUs as well as GPUs. OpenAI hit the wall first because they use agents more than almost anyone, so at least the rest of us know what's coming. Every company that rolls out agents at scale is going to need a lot more infrastructure under them than it planned for
