Leaving the AI Safety Summit after some constructive discussions today and yesterday. I voiced how open-source was today the safest way to develop AI, putting this transformative technology under the highest level of scrutiny. With many others, we recalled the enormous opportunities that AI brings for better education, better healthcare, unlocking critical science problems, and making our jobs more rewarding. Transparency and fast information flow across different actors are needed to continue enabling these opportunities. Finally, we were many to stress how any new institutions measuring AI progress should be fully independent to avoid the pitfalls of regulatory capture. And it appears we have been heard! We must ensure that any such institution involves the entire world. More data is needed to understand the limitations of current models, and we look forward to engaging with the AI community to jointly agree on a scientific monitoring framework around new AI capabilities in the coming year.
