EU Classifies ChatGPT as a Very Large Online Search Engine Under the DSA

The European Commission designated ChatGPT as a Very Large Online Search Engine under the Digital Services Act on 31 August 2026, placing it alongside Google and Microsoft. The classification subjects a transformer-based conversational model to DSA obligations — algorithmic transparency, ad-targeting restrictions, risk mitigation — designed for crawl-and-index search engines. Compliance is due by end of December 2026. How these rules map to generative AI remains unsettled.
