This week’s essential news, papers, reports, and ideas on AI governance:

• The EU published the template for the mandatory summary of the content used for AI model training, an important step for AI transparency. The purpose of this summary (which must be made publicly available) is to increase transparency and help ensure compliance with copyright, data protection, and other laws.
• OpenAI and the UK have agreed to a voluntary, non-legally binding partnership on AI to support the UK’s goal of ‘building sovereign AI in the UK.’ Pay attention to how it treats AI as an end, not as a means.
• Singapore has developed Southeast Asian Languages in One Network (SEA-LION), a family of open-source LLMs that better capture Southeast Asia’s peculiarities, including languages and cultures. Multilingualism has been fueling the new AI nationalism.
