French AI startup Mistral released its new open-weight model, Mistral Large 4, on Thursday, positioning it as a leading tool for coding and cybersecurity defense. The company stated that the model was trained on 3,800 Nvidia Grace Blackwell GPUs located in European data centers. Brad Medairy of Booz Allen Hamilton reported that the model matched the vulnerability detection rates of other frontier cyber models while offering a favorable cost structure. Mistral emphasized that the open-weight design allows enterprises to host the model within their own ecosystems, ensuring data privacy and control.
