Git packfiles use delta compression, storing only the diff when a 10MB file changes by one line, while the objects table stores each version in full. A file modified 100 times takes about 1GB in Postgres versus maybe 50MB in a packfile. Postgres does TOAST and compress large values, but that’s compressing individual objects in isolation, not delta-compressing across versions the way packfiles do, so the storage overhead is real. A delta-compression layer that periodically repacks objects within Postgres, or offloads large blobs to S3 the way LFS does, is a natural next step. For most repositories it still won’t matter since the median repo is small and disk is cheap, and GitHub’s Spokes system made a similar trade-off years ago, storing three full uncompressed copies of every repository across data centres because redundancy and operational simplicity beat storage efficiency even at hundreds of exabytes.

这话听起来只是个比喻，但一传开，就被解读成 AI vs 人类的「效能大战」。Altman 到底想表达什么？简单说，他觉得大家批评 AI 时，总拿「训练模型」的总能耗和人类「回答一个问题」的瞬间能耗比，这不公平。。关于这个话题，服务器推荐提供了深入分析
