EU AI Act Takes Effect: Undisclosed AI Hallucinations Face Heavy Fines

SpiritRealistic8174 · reddit · 2026-08-02

On August 2, Article 50 of the EU AI Act officially took effect. The new regulation mandates that deployers must disclose AI-generated text published to inform the public on matters of public interest (unless reviewed by a human or under editorial responsibility).

This means firms publishing reports with AI hallucinations without disclosure face legal risks and severe fines. The article notes that big consulting firms like PwC are highly vulnerable, having already been caught using AI-generated text with fake citations—hallucinating an entire product framework and business dealings with multiple nations. Deloitte also had to refund a client over similar data issues.

With platforms like LinkedIn adding AI slop buttons and Substack using Pangram to detect AI writing, the pushback against unaccountable AI content is gaining real legal teeth.
