02 / NIST AI RMF

What NIST AI RMF requires

AI-specific. It addresses risks such as validity, reliability, safety, security, accountability, explainability, privacy and harmful bias in AI systems across their lifecycle.

  1. 01GOVERN: set policies, accountability, culture and third-party controls for AI risk across the organization.
  2. 02MAP: establish each AI system's context, purpose, categorization, benefits, costs and impacts.
  3. 03MEASURE: select metrics and test, evaluate, verify and validate AI systems for trustworthiness characteristics; track risks over time.
  4. 04MANAGE: prioritize and treat AI risks, manage third-party risk, and monitor deployed systems with response and recovery plans.
  5. 05Optionally build use-case or sector profiles that select and tailor the subcategories that matter.

03 / OMB M-25-21/22

What OMB M-25-21/22 requires

Together they cover the federal AI lifecycle: choosing and contracting for AI, then testing, assessing and monitoring it in use. Vendors feel M-25-21 indirectly through M-25-22 clauses.

  1. 01Govern AI through a Chief AI Officer, governance board, compliance plan and annual use case inventory (M-25-21).
  2. 02Meet seven minimum practices for each high-impact AI use by 2026-04-03, or stop using it (M-25-21).
  3. 03Write contract terms that bind vendors to M-25-21 high-impact practices (M-25-22).
  4. 04Secure contractual rights to test and monitor delivered AI with agency-held data (M-25-22).
  5. 05Bar vendors from training on non-public agency data and protect against vendor lock-in (M-25-22).

Optional evidence · where Planisphere fits

Keep a record anyone can check

When your team meets a duty, Planisphere can seal the event it reports as a receipt.

01 · Your teamRecord the event

A disclosure shown, a review signed, a model change approved: the event your system reports.

02 · PlanisphereSeal it

The event becomes a sealed receipt, dated and attributed to whoever is signed in.

03 · AnyoneCheck it

Paste the receipt into Verify. No account or key.

A record supports your compliance evidence process. It is not a legal finding or a certification. Systems that call Planisphere's gate API can also hold or refuse an action before it runs.
