1/2 We've heard of the curse of dimensionality. But what about the curse of multilinguality? "If you try to pack more languages into the same size model, they are each going to degrade," said @shaynelongpre.bsky.social of @mit.edu at the Simons Institute.

Excited to publish this piece!

Policymakers must recognize the open source AI ecosystem is where influence is being negotiated: not just which models exist, but which are used; not just who can train a trillion-parameter network, but who can make it deployable, modifiable, and relevant, say Lucie-Aimée Kaffee and Shayne Longpre.

I’ll be hanging out at our poster on membership inference, but in the same slot Brian Lester will present our work on “The Common Pile v0.1: An 8TB Dataset of Public Domain and Openly Licensed Text” (poster 102)! [https://arxiv.org/abs/2506.05209]

Who is winning the open AI race? Our new study Economies of Open Intelligence maps @hf.co 851k models' downloads 2020→2025. 1) Power rebalance: US tech ↓; China + community ↑ 2) Models size & efficient ↑ (MoE, quant, multimodal) 3) Intermediary layers ↑ (adapters/quantizers) 4) Transparency ↓ /🧵

This is some legit really impressive work!!

It is critical for scientific integrity that we trust our measure of progress. The @lmarena.bsky.social has become the go-to evaluation for AI progress. Our release today demonstrates the difficulty in maintaining fair evaluations on the Arena, despite best intentions.

How should regulatory proposals adapt to the prevalence of general-purpose AI when the global geopolitical order is being reconfigured? @atoosakz.bsky.social, Deirdre K. Mulligan, @randomwalker.bsky.social, @alondra.bsky.social, & @shaynelongpre.bsky.social weigh in: youtu.be/cRsbjGFPJaM?...

🛬 in Singapore for #ICLR2025! DM me to catch up—but only if you have a local food/bar/event rec!

Thrilled our global data ecosystem audit was accepted to #ICLR2025! Empirically, it shows: 1️⃣ Soaring synthetic text data: ~10M tokens (pre-2018) to 100B+ (2024). 2️⃣ YouTube is now 70%+ of speech/video data but could block third-party collection. 3️⃣ <0.2% of data from Africa/South America. 1/

📍EVENT: Day 2 of our “AI and Democracy” symposium will be kicking off shortly. Programming will begin with welcome remarks from George Deodatis @columbiaseas.bsky.social at 9:30am ET. #AIDemocraticFreedoms Watch the full event on our livestream here: www.youtube.com/watch?v=X1gj...

Very excited to release Kaleidoscope—a multilingual, multimodal evaluation set for VLMs, built as part of our open-science initiative! 🌍 18 languages (high-, mid-, low-) 📚 21k questions (55% require image understanding) 🧪 STEM, social science, reasoning, and practical skills

Panel 1: Regulating AI in a Time of Democratic Upheaval starts in approximately 5 minutes. Panelists: @atoosakz.bsky.social, @randomwalker.bsky.social, @alondra.bsky.social, and Deirdre K. Mulligan. Moderator: @shaynelongpre.bsky.social. #AIDemocraticFreedoms

This week, @stanfordhai.bsky.social released the 2025 AI Index. It’s well worth reading to understand the evolving ecosystem of AI. Some highlights that stood out to me: 1/

Excited to speak at the workshop on Technical AI Governance in Vancouver this summer! #ICML2025

Technical AI Governance @ ICML 2025@taig-icml.bsky.social · last yr.

📣We’re thrilled to announce the first workshop on Technical AI Governance (TAIG) at #ICML2025 this July in Vancouver! Join us (& this stellar list of speakers) in bringing together technical & policy experts to shape the future of AI governance! www.taig-icml.com

#AI is evolving fast, and so are its flaws. A fresh approach to finding and reporting AI bugs is long overdue. Great initiative by @shaynelongpre.bsky.social and team, transparency and accountability in AI development are essential! #AISafety #ResponsibleAI #AIEthics #MIT

Thrilled to be at #AAAI2025 for our tutorial, “AI Data Transparency: The Past, Present, and Beyond.” We’re presenting the state of transparency, tooling, and policy, from the Foundation Model Transparency Index, Factsheets, the the EU AI Act to new frameworks like @MLCommons’ Croissant. 1/

Really excellent explainer by @shaynelongpre.bsky.social‬ that clearly lays out what's at stake in the "AI crawler wars"

Shayne Longpre@shaynelongpre.bsky.social · last yr.

I wrote a spicy piece on "AI crawler wars"🐞 in @technologyreview.com (my first op-ed)! While we’re busy watching copyright lawsuits & the EU AI Act, there’s a quieter battle over data access that affects websites, everyday users, and the open web. 🔗 www.technologyreview.com/2025/02/11/1... 1/

Re: the FTC and the platforms We *should* be concerned about platform power over speech, but it isn’t censorship. As the Supreme Court said last year, the companies’ editorial decisions to moderate content are protected by the First Amendment. 1/

Let’s see if the algorithm and data remains transparent.

I compiled a list of resources for understanding AI copyright challenges (US-centric). 📚 ➡️ why is copyright an issue for AI? ➡️ what is fair use? ➡️ why are memorization and generation important? ➡️ how does it impact the AI data supply / web crawling? 🧵

Great point by @shaynelongpre.bsky.social on the AI crawler wars: "Unless we can nurture an ecosystem with different rules for different data uses, we may end up with strict borders across the web, exacting a price on openness and transparency." www.technologyreview.com/2025/02/11/1...

AI crawler wars threaten to make the web more closed for everyone

There’s an accelerating cat-and-mouse game between web publishers and AI crawlers, and we all stand to lose.
