Europe ranks ChatGPT among its most closely watched services, the first generative AI targeted by the DSA
The European Commission on Monday 31 August designated ChatGPT as a "very large online search engine" (VLOSE) under the Digital Services Act (DSA), alongside Reddit and Roblox, classed as "very large platforms" (VLOP). The trigger threshold is met: these services reach at least 45 million monthly users in the Union. It is the first time a generative AI falls under this regime, until now reserved for the large social networks and marketplaces. OpenAI has four months, meaning January 2027, to comply with heavy obligations: to assess and reduce the systemic risks of its service (protection of minors, users' mental health, spread of illegal content), open its data to vetted researchers and submit its setup to an independent audit. For Brussels, the case is also a test: to regulate an American AI giant without stifling the rise of European champions such as Mistral, which could cross the same threshold tomorrow.
