BRUSSELS (Reuters) -Microsoft will likely sign the European Union's code of practice to help companies comply with the bloc's landmark artificial intelligence rules, its president told Reuters on Friday, while Meta Platforms rebuffed the guidelines. Drawn up by 13 independent experts, the voluntary code of practice aims to provide legal certainty to signatories. The code is part of the AI Act which came into force in June 2024 and will apply to Google owner Alphabet, Facebook owner Meta, OpenAI, Anthropic, Mistral and thousands of companies.
