Questions this page answers
- How many AI hallucination court cases were added in October 2026?
- 111 cases entered the dataset between Oct 1, 2026 and Oct 22, 2026. The month is partial: the count stops at the Oct 22, 2026 cutoff and the final figure is due Nov 2, 2026.
- What does "new" mean here?
- New means the date a case entered the AI Vortex dataset (first_seen), not the decision date. Until 2026-10-20 that date was reconstructed from the dataset's commit history (2026-06-25 is the initial import of the existing record, so June is not a month of findings); from 2026-10-20 the refresh stamps it.
- Are sanction amounts added up across countries?
- No. Amounts are grouped by the currency the source states. 6 new matters record a US dollar amount, totalling USD 14,751. Other currencies, and amounts with no stated currency, are counted but never summed.
