Description

The RHTAS Model Transparency CLI image can be used to sign and verify AI/ML workloads

Solution

The Model Transparency CLI Image is a containerized command-line tool for signing and verifying AI/ML workloads against a private Red Hat Trusted Artifact Signer (RHTAS) instance. It lets teams create signatures and attestations for model artifacts and validate them at build or deploy time using enterprise trust material (e.g., Fulcio/Rekor).
