Context & Analysis

The European Commission's designation of ChatGPT as a Very Large Online Search Engine under the Digital Services Act marks a significant regulatory shift for OpenAI in the EU. Unlike typical search engines, ChatGPT's conversational AI presents unique challenges for compliance, particularly around content moderation and algorithmic transparency. The DSA's requirements to protect minors and mental health, and to curb illegal content, will likely force OpenAI to invest in new safety measures and reporting mechanisms by the end of December 2026. Reddit and Roblox, designated as Very Large Online Platforms, face similar obligations, reflecting a broader EU approach to holding major digital services accountable for their societal impact. The designation underscores the EU's proactive stance in regulating AI, potentially setting a precedent for other jurisdictions.
