EU classifies ChatGPT, Reddit, Roblox as highest-risk platforms
First reported
Ars Technica ran this on , a day before the other 2 sources picked it up.
- ChatGPT, Reddit, and Roblox each crossed 45 million monthly EU users, triggering stricter EU Digital Services Act rules designed for the largest online platforms.
- The three services must now remove illegal content faster, protect minors better, and face fines up to 6 percent of global revenue for non-compliance by year-end.
- This expands EU oversight of generative AI tools, following an investigation into X's Grok chatbot and building on the EU's new AI Act enforcement.
Where they differ
