EU Designates ChatGPT as VLOSE, Bringing It Under Strictest DSA Rules

On August 31, the European Commission designated OpenAI's ChatGPT as a Very Large Online Search Engine (VLOSE) under the Digital Services Act, while Reddit and Roblox were named Very Large Online Platforms (VLOPs). ChatGPT becomes the first standalone AI service in the EU's strictest platform category and must meet additional DSA compliance requirements within four months, marking a new phase in EU regulation of generative AI.

Confirmed

• The designation is based on reaching the DSA threshold of 45 million average monthly EU users (cited across multiple posts)
• ChatGPT must comply with stricter obligations including risk assessments, mitigation measures, independent audits and data transparency, on par with Google and Amazon
• The companies have four months to comply; some accounts say OpenAI must complete risk assessments and remediation by December 2026, covering minors' protection and mental health
• A stated reason for the search-engine classification is ChatGPT's ability to respond to prompts via web search
• Added duties include preventing misuse for illegal content, election manipulation or user harm; non-compliance may trigger fines
• @ccerrato147 reports ChatGPT Search has 159 million monthly active users in the EU, cited by the Commission as grounds for tougher oversight; some accounts also mention Anthropic and Reddit as affected

Unconfirmed

• The 159 million MAU figure comes from a single account and awaits official confirmation

Why it matters

• Classifying ChatGPT as a "search engine" rather than an "online platform" means a generative AI service is for the first time regulated as an information-retrieval gateway, setting a precedent for other AI assistants
• The 45-million-MAU line separates ordinary services from the strictest obligations
• @ccerrato147 criticizes Europe for preferring to regulate innovation over building comparable domestic products; @gandamuml argues consumer LLMs may call external search but that is not their fundamental nature, and regulators should distinguish the two; @dejanseo mocks generative search being folded into traditional search regulation
