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.

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.

Wie kann KI offen & verantwortungsvoll gestaltet werden? Zwei neue Publikationen fassen Ergebnisse der Konferenz „Yes, we are open!?“ zusammen. Die Veröffentlichungen bieten Empfehlungen für Politik & Praxis – für eine faire, zukunftsfähige KI. 🌍🤖 www.weizenbaum-institut.de/news/detail/...

Together with @giadapistilli.com we wrote “Advertisement, Privacy, and Intimacy: Lessons from Social Media for Conversational AI”. We explore the risks when ads meet chatbots & intimacy- and why open source offers a better path. huggingface.co/blog/giadap/...

🚨 Releasing INTIMA (Interactions and Machine Attachment Benchmark): an evaluation framework for measuring how AI systems handle companionship-seeking behaviors. huggingface.co/papers/2508.... Thread on what we discovered, together with @frimelle.bsky.social and @yjernite.bsky.social

🤖💬 How do different AI models handle companionship? Some say GPT-5 feels “colder” than o4 - but what does that really mean when users look for emotional support? We built the AI Companionship Leaderboard to find out 👉 huggingface.co/spaces/frime...

🗺️ 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...

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.

Why was Grok taken down? No one knows for sure. But here’s the thing: You can flip a model’s entire vibe with just one line in the system prompt. Just ran this on @hf.co playground. Same question, two totally different answers 👇

Great blog post on *Digital Sovereignty and OS AI* led by the fantastic @frimelle.bsky.social! Digital sovereignty for AI needs to properly account for: 📚 data 🧑‍🔬 technology 💽 infrastructure ⚖️ regulation Open/transparent AI contributes to all, read for some concrete examples! hf.co/blog/frimell...

❗️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.

Just met Chris Manning he said “we seem to be doing well” The younger me would have been proud hearing this. #iclr2025

I’m in Singapore this week for #ICLR2025 - co-organising the workshop on GenAI Watermaking sites.google.com/view/genai-w... and giving a keynote on policy & dataset transparency at the MLDPR workshop mldpr2025.com/schedule/

🚨 Our comments on the 3rd draft of the EU Code of Practice for GPAI developers are out! 🚨 Some promising updates—but also concerning choices that could harm transparency & open AI development. A quick breakdown of the blogpost with @yjernite.bsky.social 🧵👇

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

Was sind eigentlich diese KI-Agenten, über die jetzt alle sprechen? 🤖 Die @dlfkultur-Folge zu KI Agenten erklärt es super! Ich durfte über die Rolle von Open Source sprechen; denn Transparenz & Anpassbarkeit sind entscheidend. 🎧 Hier anhören: www.deutschlandfunk.de/ki-agenten-k...

When I say my name, people start speaking French to me, although my French is basic. That also happens with AI systems. We wrote a whole paper on that, testing across models for presumed cultural identity based on names w/ Siddhesh Pawar @rnv.bsky.social @iaugenstein.bsky.social

What a week in Paris with the AI Action Summit! From transparency and open source AI to sustainability and global alignment, the challenges ahead will require collaboration across policy makers, researchers and AI developers. On a more fun note, @hf.co had a huge party with amazing people 🤗

How should AI tools be designed to support rather than replace workers? At the Reshaping Work conference, I led a roundtable exploring AI’s impact on labor. We published a blogpost on our key takeaways on responsible AI and the future of work w/ Franco Bastida 🔗 www.rsm.nl/discovery/20... 🧵👇

@wikipedia.org is vital for #NLP, yet little research contributes back to the Wikimedia community. To bridge this gap, we are organizing #WikiNLP to advance both. w/ Isaac Johnson (@wikimediafoundation.org) @akhilarora.bsky.social @frimelle.bsky.social @tiziano.bsky.social @indiiigo.bsky.social

I was quoted in an article about the French Lucie AI. There were still a lot of problems with the model and how and when it was deployed. But seeing new smaller models being developed is an exciting direction for the next years of AI development to come! www.lapresse.ca/affaires/tec...

Watching AI evolve has been a wild ride. From explaining why we'd bother generating a sentence with a neural net to clarifying that AI isn’t a magic, all-knowing box. Today, with the EU AI Act's first provisions in force, AI literacy isn’t optional. It’s foundational. 🧵

It's so important not to discourage #data sharing but instead try to push for transparency when regulating #AI, says @frimelle.bsky.social on the last panel of the day on #OpenSourceAI. 👏👏👏

"High-quality efficient AI models are no longer the exclusive domain of tech giants with huge hardware resources. Europe could compete on “efficiency, specialisation and responsible AI development" with “small” AI models like DeepSeek" - @frimelle.bsky.social www.politico.eu/article/euro...

After a long holiday, finally back! 2025 goals I’m excited about: 🌱 Advocate for transparent & responsible AI development 💪 Balance work travel with home-cooked meals 🤝 Support diverse voices in AI legislation 📚 Research on AI policies and their technical implications

As I wrote last week: "As other information sources fall, Wikipedia’s stubborn independence becomes more vital than ever. The attacks from [the right] aren't just about an online encyclopedia — they're part of a broader assault on any information source that refuses to be controlled."

So glad you asked! The public-domain class of 2025 includes Hemingway’s A Farewell to Arms, Woolf’s A Room of One's Own, the 1.0 versions of Popeye and Tintin, Ravel’s “Boléro,” and the first recording of Gershwin’s “Rhapsody in Blue” - my favorite in this bunch.

...to immediate large-scale risks and to collaborative solutions supported by evidence helps - as long as developers disclose enough about their design choices. full blog here: hf.co/blog/yjernit... based on our submitted response with @frimelle.bsky.social and @brunatrevelin.bsky.social 🤗 2/2

I appreciate so much being able to do policy work in the open for open-source AI, a topic that I think will affect all our lives. Finally added my responses to the EU AI stakeholder consultation and the US BIS response for @hf.co at huggingface.co/datasets/hug...

Excited to share our new article designed to help open source developers navigate the EU AI Act! You might be asking, "What does the EU AI Act mean for my projects?" We’ve just published a guide with @brunatrevelin.bsky.social @yjernite.bsky.social huggingface.co/blog/eu-ai-a...

Worked on a little UI for displaying the outputs of reasoning models on HuggingChat... Trying to find the right balance between letting users see the raw model output but also making the final answer easier to parse. QwQ can be *very* verbose so it seemed useful to give a summary at the end.

'AI influencers' show how AI scales the exploitation of women’s images, monetising stolen content, erasing its origins. But let’s not forget that even if the images are not deep fakes, models are still trained on pictures of real women, without consent. www.wired.com/story/ai-pim...
