Tinfoil Private Inference

Proceed with caution

Why

Strong cryptographic-verification story and a genuine differentiator (multi-GPU CC, open-source verifier, Red Hat OSS partnership) fit pv's privacy posture, but it is a startup with no published independent audit of its own stack and unquantified overhead on its own site — verify the attestation chain and cost ourselves before relying on it.

Next

Run Tinfoil's client-side attestation verifier against a live enclave for a target model, independently confirm the Sigstore transparency-log match, and benchmark token latency/throughput vs a non-confidential baseline on our actual prompt sizes (small + large batch); test specifically for attestation freshness/nonce and patch-level cert validation per the Trail of Bits findings.
