China’s Z.ai claims it can match Mythos on cybersecurity

China's Zhipu AI (Z.ai) has released its open-weight GLM-5.2, which researchers claim can match Mythos in certain bug-finding and cybersecurity scenarios. While GLM lags behind models from Anthropic and OpenAI in other tasks, this advancement shows China reducing the gap in capabilities between its models and those from the US. The US government is concerned about this development, as it has tried to limit China's access to powerful models like Anthropic's Mythos and Fable, along with the necessary hardware. The Trump administration has taken steps to restrict China's access to advanced AI technologies.
