Builder Questions If Zhipu AI Model Matches Claude Mythos Versatility

Top post: @kimmonismus “Supposedly, "a new model from" from zAI is said to be at least as strong as Fable5 in cybersecurity-related aspects. I did some research and only came across a Wall Street Journal article, which, however, does not refer to a new model, but to GLM 5.2 as a relatively new model that was released recently. So either GLM 5.2 is stronger than people think, or the news being circulated is misleading. According to WSJ, Zhipu AI’s GLM-5.2 can match top US models in some bug-finding scenarios, and China’s 360 Security says its new Tulongfeng tool is comparable to Anthropic’s Mythos.”
