Most Multilingual benchmarks measure what models know, not what they can reliably do. Our #ACL2026 paper introduces functional benchmarks in six languages from English to Yoruba to test whether models can actually execute tasks across languages, not just answer fixed questions about them. 🧵1/n

Sam D'Alonzo is presenting "Helpful, Harmless, Honest? Reconsidering RLHF as Survey Design and Content Moderation," our paper that explores these theories in depth, on Sunday @ 10:45-12:15 in Joyce. Collaborative work also with Frauke Kreuter.

Some personal news: I've signed a contract for a book! It's called REGIME CHANGE and it's published with Princeton University Press. More details as they become available.

Thanks for the signal boost, @jlkoepke.bsky.social! We wrote this paper to respond to real confusion we saw in various bills and in conversations with legislators. So while parts may be obvious to academics steeped in this work, hopefully it can give those working in AI policy some useful clarity.

more folks working on 'ai policy' — specifically policies seeking to prevent discrimination by ai systems in part through the use of impact assessments and audits — should read this paper by jennifer wang, @aselbst.bsky.social, @s010n.bsky.social, and @geomblog.bsky.social. arxiv.org/pdf/2506.17347

In the beginning of November, Kate and I met to think more about how to continue the work from our tech policy press blogpost on AI sovereignty. She mentioned she’d been reading Laleh Khalili's works on oil in the Middle East and that she couldn’t get AI out of her head.

'Sovereignty' Myth-Making in the AI Race

Tech companies stand to gain by encouraging the illusion of a race for 'sovereign' AI, write Rui-Jie Yew, Kate Elizabeth Creasey, Suresh Venkatasubramanian.

Very glad to be a part of a new paper detailing how developers and developer platforms can prevent AIG-NCII, a form of image based sexual abuse that disproportionately harms women and girls. Thanks to all the collaborators and Max Kamachee & @scasper.bsky.social for leading this important project!

Did you know that one base model is responsible for 94% of model-tagged NSFW AI videos on CivitAI? This new paper studies how a small number of models power the non-consensual AI video deepfake ecosystem and why their developers could have predicted and mitigated this.

ACM members/computing researchers who should be members interested in contributing should join the subcommittee's mailing list! One of our goals here is to build policy coalitions across institutions so we can do more as a collective 💪 and balance special interest groups.
