Microsoft is set to sign the EU's AI Code of Practice, a voluntary framework designed to help companies comply with the upcoming AI Act enforceable from August 2025. The code requires respecting copyright, transparency in model training, responding to opt-out requests, and publishing documentation about AI risks. Meanwhile, Meta has refused to adopt these guidelines, potentially facing increased regulatory scrutiny. Companies violating the AI Act could face penalties up to 7% of annual sales. This divide between tech giants reflects the evolving regulatory landscape for AI in Europe.
