Product

Know when your AI model dependencies change — and whether it matters to you.

PinDiff monitors the external models your software depends on, tracks the revisions you use, shows exactly what changed upstream and keeps the evidence — so your team knows when something needs attention.

From an upstream change to your next decision

Six questions, answered in order. Each step builds on the one before it.

  1. Monitor

    “Did the model change?”

    Monitor upstream model changes

    PinDiff watches supported model repositories for changes to weights, licences, remote code, access, documentation and repository state.

  2. Revision

    “Which revision do I depend on?”

    Know which revision you depend on

    Record whether your dependency uses an exact commit, tag, branch, main/latest or an unknown revision.

    revision 3f9a2c1 Pinned
    revision main Floating
    Example
    Explore Revision Tracking
  3. Exposure

    “Does the upstream change matter to my dependency?”

    Separate the change from your exposure

    The same upstream change means different things for a pinned commit and for a dependency that follows main.

    1. UpstreamWeights changed
    2. Your dependencyrevision = main Floating
    3. ExposurePotentially affected
    1. UpstreamWeights changed
    2. Your dependencyrevision = 3f9a2c1 Pinned
    3. ExposureRecorded pinned revision does not move automatically

  4. Diff

    “What exactly changed?”

    See exactly what changed

    Compare two observed states without digging through raw repository history.

  5. Evidence

    “What did PinDiff record?”

    Keep the evidence

    PinDiff keeps dated observations so your team can reconstruct what changed and when.

  6. Alert

    “Tell me when I need to look.”
