An exchange on social media platform X has sparked discussion regarding the timeline for Chinese large language models to reach the performance level of Anthropic's Fable model. When a user asked when Chinese models might achieve this benchmark, Tesla Motors CEO Elon Musk suggested "probably Q1 2027." However, Zhipu AI founder Tang Jie promptly countered, stating, "It won't take that long."

This dialogue follows Zhipu AI's recent release and open-sourcing of its new flagship model, GLM-5.2. The model scored 74.4 on the FrontierSWE programming benchmark, a result approaching the performance of Anthropic's top-tier Claude Opus 4.8 model. Furthermore, in a global blind test involving millions of users on the front-end development evaluation platform Code Arena, it ranked first among all available models worldwide.

The "Fable" model referenced in the discussion is Anthropic's recently released "Mythos-level" series model, Claude Fable 5. This model demonstrates exceptional capabilities in software engineering, visual understanding, and long-horizon task planning. It can handle complex tasks such as migrating 50 million lines of code and incorporates dynamic safety mechanisms to prevent misuse.
