ChatGPT Regulation in EU: What the Digital Services Act Means

The European Union has placed OpenAI’s ChatGPT in a new regulatory category. Under the Digital Services Act (DSA), ChatGPT is now treated as a Very Large Online Search Engine. That’s a legal term with weight: it means the platform must comply with rules usually reserved for the likes of Google or Facebook. The DSA’s primary goal is to make major online services more accountable for the content they distribute and the risks their systems might pose to society.

In practical terms, this classification triggers a host of new requirements. OpenAI must now show how it reduces the risks of ChatGPT’s outputs—especially where those outputs might affect young users, contribute to mental health challenges, or spread illegal material. For AI companies, this marks a shift from voluntary trust-and-safety efforts to compliance with enforceable European law.

The DSA isn’t vague: it asks for actual mechanisms to identify, assess, and mitigate specific harms. For ChatGPT, this means OpenAI will need to document how it deals with risks such as underage users accessing inappropriate content, the model delivering potentially harmful advice, or generating responses that violate European law.

The law could require age verification systems, explicit warnings, or restrictions on certain types of information. OpenAI may need to publish detailed risk assessments, open the black box of its moderation practices, and submit to audits by EU authorities. These aren’t light tweaks—they touch the core of how generative AI platforms operate.

For AI companies operating in or targeting the EU, the DSA’s provisions come with hefty compliance costs. Risk assessments, third-party audits, enhanced content moderation, and legal consultations all add up. Smaller firms may struggle to match the resources of tech giants. For OpenAI, with its headline product flagged as a major platform, the challenge is not just technical—it's strategic.

Companies that proactively align with these regulations may gain trust with European consumers and regulators, but they'll also face higher overhead. Meanwhile, firms slow to adapt risk fines, reputation damage, or even being blocked in the EU market. The playing field for generative AI is being reshaped by legal compliance as much as by technical innovation.

The EU's focus on minors and mental health is pointed. ChatGPT’s outputs can be unpredictable—ranging from creative prompts to, at times, problematic advice or exposure to adult content. The DSA expects OpenAI to guard against these risks or face potential penalties.

Illegal content is another flashpoint. While ChatGPT is a text generator, its ability to produce content on demand means it could inadvertently facilitate the spread of banned or harmful material. The DSA’s stance is clear: platforms must act to prevent this or accept legal consequences. For businesses using or integrating ChatGPT, this means a greater need for monitoring, filtering, and compliance measures in every customer-facing implementation.

For organizations deploying large language models in Europe, the message is simple: compliance isn’t optional. Integrating ChatGPT or similar AI into products now demands a closer partnership with legal, risk, and technical teams.

We’ve seen in our own consultancy work that early investment in responsible AI governance pays dividends. It not only reduces the risk of regulatory setbacks but also builds a foundation of trust with users. As regulators get more specific, vague promises of "AI ethics" won’t cut it—companies need documented, auditable safeguards. The era of light-touch AI deployment in Europe is drawing to a close, and those who adapt fastest will be best positioned for long-term success.
