By tracking only differences between consecutive states rather than full duplicates, DeltaBox reduces AI agent checkpoint/rollback latency from seconds to milliseconds, directly enabling deeper search and larger-scale exploration for reasoning and RL tasks.
DeltaBox is a system that makes AI agents much faster by storing only the changes between checkpoints instead of copying entire sandbox states. Using new OS-level mechanisms for filesystems and process state, it reduces checkpoint/rollback time from hundreds of milliseconds to just milliseconds, enabling agents to explore more possibilities in the same time budget.
