From August 1st, the European Union (EU) regulations on artificial intelligence (AI) models officially came into effect, marking a significant step in the implementation of the AI Act – the world's first comprehensive legal framework regulating the AI field. The implementation helps the European Commission (EC) solidify its role as the world's leading AI regulatory body and set new standards influencing other countries. The AI Act was adopted by the EU in 2024. Initially aimed at regulating AI applications, EU policymakers expanded its scope after ChatGPT generated global attention in late 2022 to include Large Language Models (LLMs). Under the new regulations, general-purpose AI models must meet transparency requirements, including publicly disclosing how they build their models, revealing the use of copyrighted data in training, and providing complete information for backend developers. The most advanced AI models face more stringent requirements, with developing companies required to proactively identify, assess, and mitigate risks to society. Last year, the EC adopted a Voluntary Code of Practice developed by leading AI experts, including Professor Yoshua Bengio. Most major Western AI labs signed on, with the exception of Meta. Tom Duff Gordon, Vice President and Regional Policy Officer for EMEA at OpenAI, said the company has worked closely with the EC and will continue collaborating. The EC established the European AI Office to oversee and enforce regulations, a task considered particularly challenging.
