Q: Are AI vendors legally required to publish model cards?

In most jurisdictions, model cards are currently voluntary, though the EU AI Act (with obligations phasing in through 2026–2027) imposes technical documentation requirements for high-risk AI systems that overlap substantially with model card content. Firms operating under EU law or procuring EU-based AI tools should verify vendor compliance.

Q: What should a legal AI model card include that a general model card might omit?

Legal-specific model cards should address jurisdiction and practice area scope, performance on recognized legal benchmarks (such as LegalBench), handling of attorney-client privilege in training data, and any restrictions on use in adversarial or court-facing contexts. --- *Last reviewed: 2026-05-19 by LawyerAI Editorial Team.*
