Parity vs certified audit
Same problem space — different product class. Use Parity for a fast first-pass screen; engage a certified third-party auditor (e.g. Warden AI) or counsel when LL144 or your policy requires independent assurance.
| Topic | ParityOS (self-serve screen) | Certified third-party audit |
|---|---|---|
| Role | Internal self-serve screen (you run it on your data) | Independent third-party auditor (impartial, required nuance for LL144 posting) |
| Speed & cost | Minutes · £499/mo self-serve | Weeks · £15k+ typical engagement |
| Markets | UK · EU · US framing on one Four-Fifths engine | Jurisdiction-specific assurance programmes |
| Input | Your applicant/hire counts by cohort (CSV or table) | AEDT integration, counterfactual testing, proprietary datasets |
| Output | Counsel pack (.md / PDF) — illustrative | Legal-grade audit report, public-posting format, assurance mark |
| Monitoring | On-demand re-runs when you upload new data | Continuous monitoring as models change |
| When to use | Know your AIR before counsel invoices · internal diligence | Statutory filing · third-party assurance · board defensibility |
Ideal motion: Parity detects early · Warden or counsel certifies and defends. Parity is not a Warden replacement.
