““In preparing to release Claude Capybara, we want to act with extra caution and understand the risks it poses—even beyond what we learn in our own testing. In particular, we want to understand the model’s potential near-term risks in the realm of cybersecurity—and share the results to help cyber defenders prepare,” the document said. Anthropic appears to be especially worried about the model’s cybersecurity implications, noting that the system is “currently far ahead of any other AI model in cyber capabilities,” and “it presages an upcoming wave of models that can exploit vulnerabilities in ways that far outpace the efforts of defenders.” In other words, Anthropic is concerned that hackers could use the model to run large-scale cyberattacks. The company said in the draft blog that because of this risk, its plan for the model’s release would focus on cyber defenders: “We’re releasing it in early access to organizations, giving them a head start in improving the robustness of their codebases against the impending wave of AI-driven exploits.””

“Dans son message, le président développe l’idée selon laquelle c’est la façon dont Anthropic porte atteinte à la démocratie qui justifie cette mise au ban. « Les États-Unis d’Amérique ne permettront jamais à une entreprise d’extrême gauche, adepte du woke, de dicter la manière dont nos forces armées mènent et gagnent les guerres ! Cette décision revient à votre commandant en chef et aux excellents dirigeants que je nomme pour diriger nos forces armées », écrit-il encore, principalement en majuscules.”

Anthropic : aux Etats-Unis, le Pentagone adresse un ultimatum à la start-up pour lever les restrictions sur son IA

https://no-flux.beaude.net/wp-content/uploads/2026/02/ca9b8f9_ftp-1-aqom4zbfhgnb-052dc3c896e84b529005d034818beefc-0-0897b1d63d9047d29630e324071eaed6.jpg

“Le secrétaire à la défense américain, Pete Hegseth, a adressé, mardi 24 février, un ultimatum à la start-up d’intelligence artificielle (IA) Anthropic pour qu’elle lève toutes les restrictions à l’utilisation de son IA par le Pentagone. La jeune société californienne a jusqu’à vendredi à 23 h 01 (heure de Paris) pour s’exécuter, faute de quoi le ministre entend user d’une loi votée en 1950 qui permet de forcer une entreprise privée à produire des biens pour la défense nationale. M. Hegseth entend également, en cas de refus, faire inscrire Anthropic sur la liste des sociétés qui présentent « un risque pour les approvisionnements ».”

Claude’s new constitution

“We’re publishing a new constitution for our AI model, Claude. It’s a detailed description of Anthropic’s vision for Claude’s values and behavior; a holistic document that explains the context in which Claude operates and the kind of entity we would like Claude to be. The constitution is a crucial part of our model training process, and its content directly shapes Claude’s behavior. Training models is a difficult task, and Claude’s outputs might not always adhere to the constitution’s ideals. But we think that the way the new constitution is written—with a thorough explanation of our intentions and the reasons behind them—makes it more likely to cultivate good values during training. In this post, we describe what we’ve included in the new constitution and some of the considerations that informed our approach. We’re releasing Claude’s constitution in full under a Creative Commons CC0 1.0 Deed, meaning it can be freely used by anyone for any purpose without asking for permission.”

AWS’s Project Rainier: the world’s most powerful computer for training AI

“Project Rainier is now in use, featuring one of the world’s largest AI compute clusters with nearly half a million Trainium2 chips. AWS deployed this massive AI infrastructure project less than one year after it was first announced, with partner Anthropic already running workloads. Anthropic is actively using Project Rainier to build and deploy its industry-leading AI model, Claude, which AWS expects to be on more than 1 million Trainium2 chips by the end of 2025.”
