EU Reclassifies ChatGPT, Imposing Strict DSA Requirements on OpenAI
The European Commission has classified ChatGPT as a Very Large Online Search Engine (VLOSE) under the Digital Services Act (DSA). The decision mandates that OpenAI comply with stricter transparency and risk management obligations.

What happened?
On 31 August 2026, the European Commission formally classified ChatGPT as a Very Large Online Search Engine (VLOSE) under the Digital Services Act (DSA). This marks the first time a generative AI service has been granted this status within the EU. The decision gives OpenAI four months, until the end of November 2026, to align its operations with the more stringent regulations.
Key facts
| Beslutsdatum | 31 augusti 2026 |
|---|---|
| Sista datum för anpassning | Slutet av november 2026 |
| Regelverk | Digital Services Act (DSA) |
| Klassificering | Very Large Online Search Engine (VLOSE) |
Why it matters
The decision reflects a shift where ChatGPT is no longer viewed merely as a conversational tool, but as critical information infrastructure. OpenAI must now conduct annual risk assessments, mitigate the spread of disinformation, and open its algorithms and datasets for independent audits by EU authorities and researchers.
Who is affected?
The change primarily impacts OpenAI as the service provider, but also affects businesses and organisations that rely on ChatGPT in their daily operations. End users within the EU can expect increased transparency regarding how responses are generated and clearer source citations within the service.
Impact on the EU
The decision confirms that the EU will continue to apply its existing digital services regulatory framework to AI platforms. Stricter requirements for transparency and risk management now apply directly to OpenAI across the entire EU, which may lead to changes in how the service presents sources and handles data for European users.
What else you should know
The classification as a VLOSE means that OpenAI will be supervised by the European Commission rather than national regulatory authorities regarding systemic risks. Businesses using the service do not need to make immediate changes, but are advised to review their reliance on the platform and how it is being utilised.
