#IA agentique : une technologie prometteuse qui soulève des interrogations. Une note publiée en février par le #CIANum présente l'#IA agentique qui promet d'automatiser des tâches complexes mais appelle à y recourir avec prudence. ⤵️ vie-publique.fr/en-bref/302417…

Yann just bet a billion dollars that the entire industry is building on the wrong foundation. Large language models predict the next word. They're trained on text, so they understand language. But the real world isn't made of words. It's made of continuous sensor data: camera feeds, touch, sound. And most of that data is unpredictable. You can't predict every pixel in a video the way you predict the next token in a sentence. Generative models fail here because they try to predict everything, including noise. AMI Labs is building world models using JEPA (a method LeCun proposed in 2022 that learns abstract representations of reality and predicts in that compressed space, not in raw pixels). Action-conditioned versions let AI simulate the consequences of actions before taking them. That's not generation. That's understanding. This unlocks AI that can operate in the physical world without hallucinating: 1. Robotics that plans multi-step actions 2. Healthcare devices where errors kill patients 3. Industrial process control under safety constraints 4. Wearables that adapt to real-time sensor input If JEPA works at scale, the next wave of AI companies won't fine-tune LLMs. They'll train world models on sensor data. LeCun's CEO already predicts every startup will rebrand as a "world model company" within six months. The architecture war is starting.

Iran attacks data centers – this could lead to internet problems worldwide, - Reuters. Iran has attacked a data center in Bahrain; This is the fourth attack in three days; Amazon Web Services objects are affected; Interruptions to banking and online services are being reported in the Middle East; Amazon is shifting capacity to other regions – increasing load and slowing down; Users are reporting VPN issues and increased ping. The main point is that attacks on physical data centers can disrupt internet services far beyond the region's borders.

🔴Dans la continuité des réflexions initiées par le Président de la République sur le rôle du numérique dans la démocratie et l'impact de ces technologies pour les mineurs, Anne Le Hénanff lance la commission d'experts sur les risques et les vulnérabilités engendrées par les usages grand public de l'intelligence artificielle générative.

Let's take a minute to breathe. We are facing a real choice between two conceptions of the role of platforms in society. It's not a debate about speech, but about governance. At stake is who shapes algorithms, how decisions are made, and whether democratic societies can remain resilient in the digital space.

Henri Mosson avait été arrêté pour faits de Résistance puis deporté au camp de Natzweiler-Struthof, le seul camp nazi en France dont il était le dernier survivant. Porteur de mémoire, il était avec nous en novembre l’année passée, commémorant les 80 ans de la libération de l’Alsace. Comme tant, je me souviens de sa force de vie et d’enseignement. Pensées à ses proches.

Is McCarthy’s witch hunt back? 🧹 As a reminder: 90% of the European Parliament — our democratically elected body — and all 27 Member States unanimously voted the DSA 🇪🇺 To our American friends: “Censorship isn’t where you think it is.”

La souveraineté numérique de l’Europe est essentielle pour la compétitivité de notre économie, ainsi que pour notre sécurité et notre défense. L‘Allemagne et la France travaillent ensemble avec détermination. Merci d’être à Berlin aujourd’hui pour cela, cher @EmmanuelMacron.

They could just say Le Chat 🇪🇺 😀

The notion that AGI would have infinite returns has been used to justify investment far above expected returns (by 10x-100x) for technology that is neither AGI nor on the path to AGI

Unlearning with Friends here in Barcelona! Thank you Mozilla and @nabihasyed

Congrats @MarietjeSchaake 🙌

Another UNGA high-level week! 🇺🇳

We’ve raised €1.7B to accelerate technological progress with AI! This Series C funding round, led by @ASMLcompany, fuels Mistral AI scientific research to keep pushing the frontier of AI to tackle the most critical technological challenges faced by strategic industries.

Happy to be back in Copenhagen to debate about AI ethics @TechBBQ - Have missed you CPH!

Le CNNum est mort, vive le Conseil de l’IA et du Numérique ! Nouveau chapitre, même exigence : un conseil indépendant, lucide, collectif pour penser le numérique à l’ère de l’IA. Une boussole dans la tempête de l’IA et du Numérique. Merci à @AnneBouverot et Guillaume Poupard d’avoir accepté de prendre la co-Présidence et aux 15 membres exceptionnels de ce nouveau conseil - que des numéros 10 dans cette nouvelle équipe. Au travail !

Why are people not talking about open-source AI in the AI energy conversation? If all the frontier labs build in siloes, with a focus on each training their own big generalist models, it will require orders of magnitude more energy whereas if we push open science and open-source with a focus on smaller more efficient models and big models being shared for all, a country like the US could be more competitive and get more economic benefits with a fraction of the energy. Am I missing something?
