For
AI developers and vendors
What it covers
- Model performance failure against measured thresholds
- Vendor and adopter protection when an AI system underperforms its specification
Watch out for
- It answers a different question from AI liability: performance, not third party claims
- The HSB small business add on has very small limits and is sold through partner carriers' policies, not as a standalone broker placement
Who it fits
- AI vendors selling on measurable performance claims
- Enterprises adopting AI under performance based contracts
Who it does not fit
- Companies whose main exposure is bias, IP, or regulatory claims (that is liability cover, not aiSure)
Frequently asked questions
How is aiSure different from Armilla or Testudo?
They are liability policies that respond to claims. aiSure is a guarantee that responds when measured model performance fails. Some programmes need one, some need the other, some need both.
