@vintcessun: Just came across this article, pretty impressive. Essentially, when AI agents do parallel exploration or tree search, each checkpoint/rollback requires backing up the entire file and process state, taking hundreds of milliseconds. DeltaBox discovered that consecutive checkpoints are actually highly similar. So instead of copying everything, just record the changes. It introduces two OS-level mechanisms…

Presented at arXiv, DeltaBox introduces OS-level mechanisms (DeltaFS and DeltaCR) for millisecond-level checkpoint and rollback in stateful AI agents by only duplicating changes between consecutive states, achieving 14ms checkpoint and 5ms rollback on SWE-bench and enabling significantly deeper tree search within fixed time budgets.
