ChatGPT designated as VLOSE under EU’s strictest platform regulations
The European Commission has designated ChatGPT as a Very Large Online Search Engine (VLOSE) under the Digital Services Act. The decision places the platform and its integrated AI agents under the EU's most stringent digital regulatory framework.

What happened?
The European Commission has classified ChatGPT as a Very Large Online Search Engine (VLOSE) under the Digital Services Act (DSA). The decision, announced on 31 August 2026, means OpenAI is now subject to the EU's strictest regulatory framework for digital platforms. OpenAI Ireland Limited reports 159.1 million average monthly users in the EU, and the company has four months to align its operations with the regulations.
Key facts
| Status | VLOSE (Very Large Online Search Engine) |
|---|---|
| Regelverk | Digital Services Act (DSA) |
| Beslutsdatum | 31 augusti 2026 |
| Månatliga EU-användare | 159,1 miljoner |
| Anpassningsperiod | 4 månader |
Why it matters
The classification shifts the legal focus from model-level safety to platform-centric obligations. This requires the platform to actively manage risks related to disinformation, manipulated content, and systemic threats to elections or public health. Furthermore, AI agents and integrated services leveraging ChatGPT inherit these expanded responsibilities.
Who is affected?
The decision affects OpenAI as well as all developers and companies building AI agents and applications on top of the ChatGPT API or ecosystem. End users and businesses within the EU are also affected, as the service must now implement more rigorous systems for risk management, content moderation, and transparency.
Impact on the EU
With 159.1 million monthly EU users, ChatGPT exceeds the 45 million user threshold defined under the DSA. OpenAI Ireland Limited has a four-month period to meet the tightened requirements, which directly impacts how generative AI and autonomous agents are provided within the European Union.
What else you should know
The VLOSE classification was confirmed by the European Commission in a press release (IP_26_1772) on 31 August 2026. This marks the first time a generative AI interface has faced such platform-wide obligations.
