Meta Platforms said Friday it will not sign the European Union’s voluntary Code of Practice for general-purpose AI, published last week, which is designed to help companies comply with the EU AI Act. The rules for general-purpose AI models take effect next month.

Joel Kaplan, Meta’s chief global affairs officer, wrote on LinkedIn that Europe is heading down the wrong path and that the Code introduces legal uncertainties for model developers and measures that go far beyond the scope of the AI Act. He added that the overreach will throttle development and deployment of frontier AI models in Europe and stunt European companies building on them.

OpenAI committed to signing the code last week. Some European companies, including Mistral, recently asked the EU to delay the AI Act by two years, but the Commission declined. ASML and Airbus were among signatories of a letter calling on the EU to delay the code for two years.
