AI Labeling Became Law on Sunday

Almost nobody's Monday leadership meeting mentioned it, because the news cycle was busy grading earnings: on Sunday, August 2, AI content disclosure became enforceable law on two continents on the same calendar day, with no coordination between them. California's AI Transparency Act went operative, requiring covered generative AI providers (over one million monthly visitors or users) to offer a free AI-content detection tool and embed visible and invisible provenance marks in AI-generated media, at 5,000 US dollars per violation with each day counted separately, enforceable by the state Attorney General, city attorneys, and county counsel. The same day, Article 50 of the EU AI Act reached its enforcement date: chatbots must disclose they are AI, deepfakes and synthetic media must carry machine-readable labels, and fines run to 15 million euros or 3 percent of global revenue. The same week, three courts closed the side doors companies were quietly relying on: Munich ruled that training in the US is not a defense against EU copyright (GEMA v. Suno), a New York federal judge let Reddit's anti-circumvention claims against Perplexity proceed, and Minnesota's ban on AI nudification apps took effect over xAI's objection. Twenty-six major model providers signed the EU's voluntary transparency code; Meta stands alone outside it, the same week the market marked it down for AI spending without a visible receivable.
