EU Online Safety Rules Now Cover ChatGPT, Reddit and Roblox

The European Commission has placed OpenAI's ChatGPT, Reddit and Roblox under the strictest tier of the EU online safety rules, a category reserved for digital services large enough to pose systemic risks to European society. Announced on Monday, August 31, the designations make ChatGPT the first AI chatbot classified as a "Very Large Online Search Engine" under the Digital Services Act, while Reddit and Roblox were labeled "Very Large Online Platforms."

The trigger is user scale. All three services reported more than 45 million average monthly users inside the EU, a threshold equal to roughly 10 percent of the bloc's population and the entry point for the Digital Services Act's heaviest obligations. With the additions, 28 platforms and search engines now operate under the regime.

The Digital Services Act is the EU's landmark rulebook for online services, and its strictest tier applies only to Very Large Online Platforms and Very Large Online Search Engines. The 45 million user line is how the Commission identifies services whose scale makes them capable of amplifying harm across the bloc, from illegal content to threats against minors and the integrity of elections. The new designations extend that logic from social networks and marketplaces to an AI chatbot, a discussion forum and a game platform.

What the EU online safety rules now demand

Each company has four months, until the end of December 2026, to assess and mitigate systemic risks tied to illegal content, protection of minors, users' mental health, electoral processes, fundamental rights and public security. In practice, the compliance work covers:

• Systemic risk assessments documenting how harmful content could spread on each service
• Moderation and child-safety safeguards, an obligation that lands hardest on Roblox given its large base of younger players
• Algorithmic transparency, with regulators able to inspect how ranking and recommendation systems work
• Independent audits and transparency reports covering how the companies enforce their own rules

The Commission's enforcement toolkit expands alongside those duties. Regulators can order changes to the platforms' algorithms, demand evidence that mitigation plans are working and open investigations without waiting for a complaint. Companies that fail to comply face fines of up to 6 percent of annual global turnover.

Why ChatGPT's classification is a milestone

The most consequential decision is how Brussels categorized ChatGPT. Treating a conversational AI assistant as a search engine is unprecedented under the DSA, and the Commission's description of the service as a hybrid, one that blends open-ended answers with search-like functions, shows how the bloc's existing digital regulation is being stretched to cover rapidly evolving AI. It is also the first time the EU online safety rules have been applied to an AI chatbot, putting AI-generated content and its influence on elections and public debate inside the scope of EU supervision.

For OpenAI, the designation carries a double burden. As the first AI company to run a flagship service under the DSA's strictest regime, it must show that ChatGPT can meet obligations designed for platforms with human-curated content. The rules around illegal content force a question that is still being settled: who is responsible when generated text crosses a legal line, and how quickly it must be removed.

For Reddit and Roblox, the sharper edge is child safety. Roblox, a gaming and creation network popular with younger users, faces the most visible compliance work around minors' protection. Reddit, a social forum hosting millions of communities, contends with moderation at scale and with how its algorithms surface content across the platform. Both must now treat those risks as systemic rather than incidental, with written assessments due before the December deadline.

Compliance work has effectively begun. The four-month window runs from the August 31 announcement, and the first deliverables are the risk assessments and mitigation plans, followed by audits and transparency reporting. How thoroughly those documents address child safety and AI-generated content will shape how the Commission exercises its new investigative powers.

For European users, the practical effects will arrive in stages. The first visible changes should be clearer reporting on how these services moderate content, more explicit safeguards for underage accounts and greater disclosure around ranking and recommendation systems. When the Commission exercises its new powers, users may also see direct alterations to the algorithms that decide what appears in ChatGPT answers, Reddit feeds and Roblox experiences.

Why this matters

The EU online safety rules are now testing whether a law written for social networks can govern AI assistants and gaming worlds. How ChatGPT, Reddit and Roblox respond by the end of December will set the template for every other service that crosses the 45 million user mark, and it decides how aggressively these platforms protect minors, police content and disclose how their algorithms work. For people in the EU, the outcome is concrete: three of the internet's most widely used services will now operate under external supervision, with the power to audit them, fine them and force changes.
