Meta has declined to sign the European Union's AI code of practice, a voluntary set of guidelines intended to support the upcoming AI Act. Meta's Chief Global Affairs Officer, Joel Kaplan, publicly criticized the code, calling it an "over-reach" and expressing concerns about legal uncertainties for AI model developers. Kaplan stated that the code includes measures exceeding the scope of the AI Act. Despite being voluntary, Meta's refusal highlights potential friction between tech companies and EU regulators regarding AI governance.
