China\u2019s Zhipu AI (Z.ai) has claimed to have developed a new AI model on par with Anthropic’s Mythos on cybersecurity capabilities.<\/p>\n<\/div>\n
According to a report by The Wall Street Journal, Zhipu’s recently launched GLM-5.2 model can match the performance of American AI models in terms of finding security bugs but still lags behind Anthropic and OpenAI’s products in other tasks.<\/p>\n<\/div>\n
The news around the new capabilities of GLM-5.2 comes at a time when the US government has grown more protective over giving access to American AI models to the world. Recently, the Trump administration asked Anthropic to shut down access to its Fable 5 and Mythos<\/a> 5 models to people outside the US. Similarly, OpenAI was recently asked to stagger the release of the GPT-5.6 model.<\/p>\n<\/div>\n As per data from OpenRouter, GLM-5.2 has ranked among the top 10 most-used AI models globally. Meanwhile, cybersecurity company Semgrep found that the Chinese AI model even outperformed Claude<\/a> Opus 4.8 in certain tasks. Meanwhile, the researchers also found that with additional prompting, GLM-5.2 and Claude Opus 4.8 could match Mythos’ bug-finding abilities.<\/p>\n<\/div>\n GLM-5.2 is a 753 billion-parameter model with a 1 million-token context window, which means that the model can be used to handle long coding sessions and large codebases without losing context.<\/p>\n<\/div>\nGLM-5.2 matches Mythos<\/h2>\n
