Italy Sets First Regulatory Standard for AI Hallucination Disclosure

Italy's antitrust authority has extracted binding commitments from DeepSeek, Mistral, and Nova to disclose hallucinations with specificity—the first enforceable standard for what "adequate" disclosure means, rather than industry self-regulation or guidelines. AI companies operating in Europe now face concrete disclosure requirements or enforcement action. The precedent matters because other EU regulators are likely to adopt it, giving Italy de facto standard-setting power across the bloc before the EU's AI Act takes full effect.
