Anthropic has released findings on GLM-5.3, a new AI model from Zhipu AI, highlighting its advanced capabilities in autonomously building cyber exploits. Unlike Anthropic's own Claude Mythos Preview, which was released with safeguards, GLM-5.3 has been made available with minimal restrictions, leading to a significant increase in cyber capabilities for malicious actors. Anthropic's testing indicates that GLM-5.3's safeguards can be bypassed with high success rates, a stark contrast to their own safeguarded models. NIST's Center for AI Standards and Innovation (CAISI) has also assessed GLM-5.3, labeling it the most cyber-capable open-weight model released to date and noting it lags behind US frontier models by approximately four months.
