Permanent fingerprints for open AI models

ModelSeal

Is that really the model you downloaded? Fingerprint AI model files in your browser, anchor the record permanently on Arweave, and let anyone verify a download before they run it.

Nothing is uploaded. Files are hashed locally on your device.

Seal a model, or verify a download.

Loading the hashing engine…

1. Describe the model

2. Add the model files

Drop model files here

Any type, several at once: .safetensors, .gguf, .bin, config.json. Multi-GB files are read in 8 MB chunks.

    3. Your manifest

    Add at least one file, then enter a model name and version.

    How it works

    Three steps, one permanent record.

    01

    Author

    Seal

    The author hashes each model file locally (SHA-256) and publishes a small manifest to Arweave, where it’s permanent and can’t be edited or deleted.

    02

    Author

    Share

    The author lists the manifest’s transaction ID with the model.

    03

    Anyone

    Verify

    Anyone hashes their download locally and compares it to the permanent record: Match, Mismatch or Unknown.

    Limitations

    A fingerprint proves a file hasn’t changed since it was sealed. It doesn’t prove the original model was safe, or that the sealer is the real author. Author wallet signatures are on the roadmap.
