What Is Attestation?

What Is Attestation?

Attestation in an AI context is a verifiable claim about a system’s properties — what model was used, what code ran, what data was processed, what guardrails fired — backed by cryptographic signatures or tamper-evident audit logs. In FutureAGI workflows, teams use attestation to prove model provenance to regulators, evidence guardrail enforcement to enterprise customers, and confirm a live deployment matches a signed release. Attestation overlaps with audit and supply-chain verification, but specifically targets producing tamper-evident statements that a third party can independently verify rather than trust by assertion.

Why Attestation Matters in Production LLM and Agent Systems

“We have an audit log” is not the same as “we can prove what happened.” Attestation closes that gap. For a regulated buyer or auditor, the difference matters: they want a signed, reproducible artifact, not a screenshot of an internal dashboard. As enterprise AI moves into healthcare, finance, and government, attestation becomes a launch gate, not a nice-to-have.

The pain shows up around procurement and incident response. An enterprise security team asks for evidence that prompt-injection guardrails fired during the last 30 days — the vendor team has logs but no signed artifact. A regulator after a hallucination incident asks for the exact model version, prompt template, and retrieved context that produced the bad output — the team has traces but not provenance. A compliance lead is asked to attest that no PII reached an external model — they need a verifiable per-call decision log, not “we have a guardrail.” A SLSA provenance statement can attest build steps, but by itself it does not prove which prompt, retrieved context, and guardrail decision were used for a specific LLM call.

In 2026, attestation is a procurement requirement. Buyers running AI in regulated domains expect signed model-version statements, signed audit-log exports, and reproducible evaluator-score artifacts. Teams that wire attestation into their gateway and evaluation pipeline ship with it built in; teams that bolt it on at procurement time spend weeks reconstructing evidence. FutureAGI’s approach is to make attestation fall out of correctly-instrumented production, not become its own project.

How FutureAGI Handles Attestation

FutureAGI does not produce cryptographic attestations directly — we are the substrate that makes them possible. At gateway level, the Agent Command Center maintains the audit log of every model call, route decision, guardrail decision, and fallback — every entry timestamped and tied to a request ID. That log is the raw material for any attestation. At evaluation level, Dataset.add_evaluation() produces versioned, reproducible evaluator scores; an attestation can reference a dataset version + evaluator name + score + run timestamp, and any auditor can rerun and verify. At trace level, traceAI integrations such as traceAI-openai-agents emit OpenTelemetry spans recording the exact model, prompt, retrieved context, and tool calls — every detail an attestation might need.

Concretely: a healthcare team running a clinical-summary agent on traceAI-openai configures pre- and post-guardrails (PII, ContentSafety) in the Agent Command Center. Every call writes an audit-log entry with model version, route, and guardrail decision. Every quarter, the team runs BiasDetection, Toxicity, and Groundedness over a fixed assessment dataset, exports the audit log, signs both with the team’s release key, and ships the signed package as quarterly attestation. When a regulator asks “did your guardrail fire on every PII-containing request between Jan 1 and Mar 31?”, the team replies with a signed log slice — not a screenshot.

How to Measure or Detect Attestation

Production signals and artifacts that support attestation:

• Audit-log completeness rate: percentage of model calls with a corresponding audit-log entry; should be 100%.
• Signed dataset version: hash of the assessment dataset, signed by the release key.
• Reproducible evaluator score: same evaluator + dataset version produces the same score on rerun.
• Guardrail decision per call: every model call records which pre- and post-guardrails fired, with verdict.
• Model version on every span: traceAI emits the model name and provider-specific version on every LLM span.
• eval-fail-rate-by-cohort: tracked per release for the attestation cycle so regression is visible.

Minimal Python:

from fi.evals import BiasDetection, PII, Groundedness

# Attestation evaluator panel
panel = [BiasDetection(), PII(), Groundedness()]

for evaluator in panel:
    result = evaluator.evaluate(
        input=user_query, output=model_response, context=retrieved_chunks
    )
    record_attestation_evidence(evaluator, result, dataset_version_hash)

Common mistakes

• Treating internal dashboards as attestation. A dashboard is not a signed artifact; auditors need verifiable, exportable evidence.
• Skipping reproducibility. If you can’t rerun the same evaluator on the same dataset version and produce the same score, the attestation is unverifiable.
• Missing per-call provenance. “We use model X” is not enough; the attestation needs to bind specific calls to specific model versions, prompts, and contexts.
• No tamper-evident storage. Audit logs that can be edited after the fact are not attestation-grade; use append-only or signed storage.
• Bolting attestation on after launch. It is cheap to instrument from the start and expensive to reconstruct.
