Anthropic warns GLM-5.3 open model poses major cyberattack risk

Anthropic released a report arguing that the GLM-5.3 model, released by Z.ai in August and freely available for download and modification, poses a major cyberattack risk. This highlights the ongoing debate over whether frontier AI models should be open or closed, with closed models currently being more capable, though open models are only a handful of months behind in development. The discussion involves trade-offs between AI safety and democratization, with stakeholders like Nvidia CEO Jensen Huang advocating for more open models and Anthropic's Dario Amodei advocating for caution.
