Hungary: Hungarian Competition Authority adopted commitments following investigation into Microsoft for allegedly inadequately informing consumers about Bing AI feature

On 30 May 2025, the Hungarian Competition Authority (GVH) adopted binding commitments in its investigation into Microsoft Ireland Operations Limited concerning the AI-based Bing search service. The proceeding examined whether the company had informed Hungarian consumers with the expected professional diligence about the AI functionalities integrated into Bing since February 2023. The Authority raised concerns over fragmented, overly complex, and partly English-only user information. Without establishing a legal infringement, the Authority accepted a voluntary commitment by Microsoft to improve transparency and support Hungarian-language AI development. Microsoft will train its AI systems using a cleaned dataset of at least 10 billion Hungarian words and will make the dataset freely accessible to other developers. The company also committed to educational measures for public officials, small businesses, and consumers. The Authority will monitor implementation closely and may impose fines for non-compliance.
