AI:AM — Mistral Large 4, Open Models and AI Cyberattacks · October 30, 2026
Notes de l’épisode
ServiceNow threat researcher Michael Freeman describes AI-driven compromises costing 5–10 cents, credential theft through support tickets, and why autonomous patching is not ready for critical infrastructure. Mistral researcher Sagar Vaze explains the rescue of Large 4 during training, its sparse trillion-parameter design, the push for stronger multimodal skills, and the case for open weights amid limited compute.
