Common questions

Common questions about AI Model Error Liability vs AI Model Output Liability vs AI Agent Mistakes vs Non-Breach Privacy & Data Leakage vs AI Model Property Damage vs AI Model Regulatory Violations

Is Armilla the only insurer writing affirmative AI liability coverage?

+

No. Armilla is one MGA/Lloyd's coverholder in a still-forming market. CASRAI's own guide on why no US state mandates this coverage documents other carriers staking out adjacent, differently-structured pieces of the same broader AI-risk frontier — this page is scoped specifically to Armilla's named six-line product and MKIII case study, not a survey of every carrier active in the space.

Does buying this insurance satisfy California SB 53's accountable-decision-maker requirement?

+

No — they are different mechanisms answering different questions. SB 53's requirement, tied to CASRAI's own NIKOLAI Commitment element in Track N9, is about who internally reviews and signs off on deploying a frontier model. An insurance policy is a separate, external instrument that transfers financial risk after that decision has already been made; it does not substitute for, or satisfy, an internal governance sign-off requirement.

What's the difference between AI Model Error Liability and AI Model Output Liability?

+

AI Model Error Liability responds to the AI simply performing badly — an accuracy shortfall or hallucination causing financial loss, with no third-party claim required. AI Model Output Liability is triggered only once a third party has a legal claim over what a specific output said or did, such as defamation or a confidentiality breach.

Is affirmative AI liability insurance a new product launched in 2026?

+

No dated 2026 launch announcement was found for Armilla's program during CASRAI's research for this page, so this page does not make that claim. It presents the six coverage lines and the named underwriter roster as current-state fact, verified directly against Armilla's own website on September 20, 2026, not as a 2026 product launch.
