Is China AI ready to match Anthropic’s Fable 5? Musk, Zhipu’s Tang clash over GLM-5.2 rise
Global No 2 ranking for Zhipu’s breakthrough AI model triggers Musk exchange over whether China can close gap with US sooner than expected

On social media platform X last week, Musk – founder of xAI, Tesla and SpaceX – responded to a post discussing when China could potentially produce a rival to Fable 5 – currently regarded as the world’s most advanced model. Musk projected the timeline would “probably” be the first quarter of next year.
Tang replied that it “won’t take that long”.
His confident comment came as Zhipu’s newly released 744 billion-parameter GLM-5.2 model recently secured the No 2 spot globally on benchmark firm Code Arena’s rankings for front-end coding abilities, trailing only Fable 5.

The launch propelled Zhipu to the world’s third-best AI lab, behind Silicon Valley heavyweights Anthropic and OpenAI, according to the Artificial Analysis Intelligence Index.
