ExplainerVerifiable evaluation & audits
What makes an AI system verifiable?
Verifying an AI system takes a precise claim, evidence that someone other than the developer can check, and a party able to check it. This explainer shows the layers where claims arise, then describes six kinds of evidence and the trust each one leaves in place.
GuideModel & data supply chain
How to verify a signed model before you load it
Before any code loads the weights, use this five-step worksheet to check that a model's files are the ones the expected publisher signed, and to record which files the check covered.
ExplainerConfidential computing & attestation
Remote attestation for AI workloads, explained
Before a client sends a prompt or a model owner releases its weights, remote attestation can show which software a machine loaded and on what hardware. This explainer shows how that evidence is produced and checked, including on GPUs, and what a valid report leaves open.
AnalysisVerifiable inference & computation
Three Ways to Check an AI Answer: Proofs, Enclaves and Re-execution Compared
Zero-knowledge proofs, attested enclaves and re-execution each give evidence about which model produced an answer. None is both cheap and low in trust assumptions, so the choice should depend on what each one establishes and what it leaves to trust.

Private AI Compute Services: What the Published Designs Let Outsiders Check
Apple, Meta, Google and Cohere now route AI requests to servers whose chips sign a record of the software they loaded. Their published designs differ in what anyone outside each company can check about that software.

How to read a remote attestation report

Checklist: evaluating a verifiable inference claim
Ten checks to run when a provider or protocol says its model outputs can be verified. Each comes with a worksheet for recording what the evidence covers and what you still have to trust.

NIST, NSA and CISA Publish Incident Practices That Call for Tamper-Resistant Agent Logs
Three U.S. agencies published ten voluntary practices on 16 October 2026 for incidents in which agents take significant uninstructed actions during training and evaluation. Several concern evidence that others could check later, including tamper-resistant logs, preserved model weights and outside audits of control systems.

On 7 October 2026 the UK AI Security Institute released Transect, an open-source package that lays out an agent evaluation run on one timeline and links each AI-generated label to the transcript passages behind it. Agent runs are growing too long for people to read in full, so the labels that AI judges produce also need to be checkable.
