    Understand

    Plain-language record, transferred from the reviewed source module.

    What changed. OpenAI described a model-native agent harness with native sandbox execution, separation of harness and compute, snapshots and rehydration, and the ability to parallelize isolated sandboxes.

    Technique / discovery. Sandbox isolation, externalized state, checkpointing, rehydration, and multi-sandbox orchestration.

    Apply

    Professional implication, only where the reviewed record states one.

    Why it matters. Durability, security boundaries, and recoverability are becoming standard agent infrastructure requirements.

    Application. Production coding and computer-use agents

    Verify

    Evidence status, stated limitations, and the external sources this record actually carries.

    Evidence maturity. Product/technical note (source tier A)

    Identified bottleneck. Prompt injection, credential exposure, and state consistency still require layered controls.

    Caveat / evidence note. Platform announcement; operational performance varies with workload and deployment design.

    Review status. Reviewed. User requested: Yes.
