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.
Policymakers Overlook How Open Source AI Is Reshaping Global Power | TechPolicy.Press
To understand and shape the distribution of power in AI, look to the open source ecosystem, say Lucie-Aimée Kaffee and Shayne Longpre.

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 ↓ /🧵
🤖 Did you know your voice might be cloned without your consent from just *one sentence* of audio? That's not great. So with @frimelle.bsky.social, we brainstormed a new idea for developers who want to curb malicious use: ✨The Voice Consent Gate.✨ Details, code, here: huggingface.co/blog/voice-c...
What does it mean if anyone’s voice can be cloned and made to say whatever someone else wants? Together with @mmitchell.bsky.social we built a first prototype, a Voice Consent Gate, to explore how consent could be built into AI voice cloning itself.
What if your most personal chat logs became the next source of ad data? @frimelle.bsky.social and I wrote an op-ed for @techpolicypress.bsky.social We look at what happens when generative AI conversations (the ones we treat as private) are turned into raw material for targeted advertising.

Neither in the United States nor in the European Union are regulations yet fully prepared for the mix of intimacy and monetization that AI chatbots can introduce, write Hugging Face's Lucie-Aimée Kaffee and Giada Pistilli. We need to learn the lessons from past failures on social media, they say.

🗺️ New blog post: Old Maps, New Terrain: Updating Labour Taxonomies for the AI Era For decades, labour taxonomies like O*NET helped us understand how tech changes work. But they were built before most work became digital-first, and long before generative AI could create whole professions in one step.
Are you afraid of LLMs teaching people how to build bioweapons? Have you tried just... not teaching LLMs about bioweapons? @eleutherai.bsky.social and the UK AISI joined forces to see what would happen, pretraining three 6.9B models for 500B tokens and producing 15 total models to study
OpenAI just released GPT-5. When users share personal struggles, it sets fewer boundaries than o3. We tested both on INTIMA, our new benchmark for human-AI companionship behaviours. 🧵
Wikipedia has long been one of my favourite places online. As AI becomes part of knowledge creation, there's a lot we can learn from its editor communities. I spoke with Daniel Wu about AI content on Wikipedia; some thoughts made it into this piece: www.washingtonpost.com/technology/2...
Volunteers fight to keep ‘AI slop’ off Wikipedia
Hundreds of Wikipedia articles may contain AI-generated errors. Editors are working around the clock to stamp them out.

New guide for open-source AI developers: Starting August 2, 2025, the EU AI Act imposes new rules on GPAI models, including open ones. What counts as GPAI? What’s exempt? What do you actually need to do? We wrote a guide (and built a tool) to help: huggingface.co/blog/yjernit...

From Replika to everyday chatbots, people form emotional bonds with AI. But what happens when an AI tells you "I understand how you feel" and you actually believe it? With @frimelle.bsky.social and @yjernite.bsky.social, we dug into something: how AI systems handle our emotional lives.

❗️New policy blogpost! The EU is speaking a lot about sovereignty. A cornerstone of digital sovereignty is and has to be open source. As AI becomes more central, the ability to govern, adapt, and understand these systems is no longer optional.

Amazing work from HF colleagues that's super relevant to AI policy - open development matches "frontier" performance 🤗 For policymakers, it means we need regulation that works for both open and closed model - not closed-first that disproportionately harms open! Good news is... 1/2
