LITMUS

Independent validation for clinical AI.

Reproducible. Auditable. Signed. We run your model in a sealed sandbox, compare it to your declared baseline, and ship a cryptographically signed report.

How it works

Step 1

Upload

Upload your training set, test set, and code tarball. All three land in a CMEK-encrypted GCS bucket inside our HIPAA BAA-covered perimeter.

Step 2

Sandbox

We run your code inside a gVisor sandbox on Confidential GKE Autopilot — no internet egress, no access to other tenants. Pipeline produces fabrication-sniff, execution, and congruence metrics.

Step 3

Signed report

A KMS HSM-backed certificate is generated and published at aivalidation.ai-heart.org/c/<slug> for external verification. Audit trail retained for 7 years.

Pricing

Per-submission pricing. No retainer required. Separate tiers for individual researchers and for companies validating commercial models.

For researchers

Academic labs, clinician-investigators, and graduate students. Free trial runs on a public dataset; paid tiers issue a signed public certificate.

For companies & vendors

Industry validation for commercial clinical-AI models. The free sample is read-only — no compute consumed, no real validation. Paid tiers produce a KMS-signed certificate.
