Meta has declined to sign the European Commission's voluntary guidelines for general-purpose AI models, arguing that they introduce legal uncertainties beyond the scope of the upcoming EU AI Act. This decision allows Meta's AI model, Llama 4 Behemoth, to operate without the added restrictions proposed by the guidelines, which aim to enhance safety and transparency in AI deployment. The European Commission maintains that compliance with the AI Act will be mandatory for all AI providers once it takes effect on August 2.
