Mistral AI lève 3 milliards d'euros : la consolidation européenne par le haut

Mené par Samsung Electronics et le Scaleup Europe Fund, le tour de table de Série D de Mistral AI porte la valorisation de la pépite française à 21 milliards d'euros. Face au duopole américain, cette injection de capital cible l'infrastructure de calcul et les capacités d'inférence souveraines pour les grands comptes et le secteur public européen. Une étape charnière pour la souveraineté numérique du continent.

Cyber Resilience Act et plan Réactiv : l'État et l'Europe haussent le ton

Le 11 septembre 2026, l'obligation de notification sous 24 heures des vulnérabilités exploitées auprès de l'ENISA est entrée en vigueur dans le cadre du Cyber Resilience Act (CRA). En parallèle, après les incidents de l'été contre la DGFiP et l'ANTS, le gouvernement a déployé le plan interministériel Réactiv pour muscler les capacités de réponse de l'ANSSI. La conformité cyber n'est plus un sujet de fin d'année, mais d'astreinte permanente.

Facturation électronique et commande publique : le défi des plateformes

Dix jours après l'entrée en vigueur de l'obligation de réception et d'émission pour les ETI, les marketplaces B2B et B2G adaptent en urgence leurs connecteurs Chorus Pro et plateformes agréées. Côté gouvernance IA, le manifeste de Dario Amodei (Anthropic) soutenu par Sam Altman pose les bases d'un ralentissement concerté sur l'auto-amélioration récursive des agents. L'exécution automatisée exige des garde-fous organisationnels immédiats.

Generating running routes with GPT-6 Astra and ChatGPT Work

Here's a neat thing I had ChatGPT Work with GPT-6 Astra (Max) do this morning: I live at . Figure out 5K and 10K running routes from me that loop from my house. Use OSM data.

Quoting Paul Ford

For a while, I must admit, it looked as if software developer roles like mine were done for. How could we fight against tireless robots? But our industry is slowly realizing that making truly cutting-edge software still requires humans to think and work together, to maximize their skill sets and to

At Anthropic, we have many guardrails in place to make sure this is happening: lots of lint rules, lots of tests, Claude-driven end to end tests, Claude-powered fuzzers running daily, automated code reviews

Smells awful : But an estimated 30 to 50 tons of dead squid remain inside the boat’s catch tank, where they have been decomposing for days. “That is nasty.
