China's Zhipu AI launches open-weight model GLM-5.2, drawing developer praise
Chinese artificial intelligence startup Zhipu AI has released its latest large language model, GLM-5.2, an open-weight system designed for complex coding and automated workflows. The model, launched last week, offers a context window of one million tokens, placing it in competition with frontier models from US firms like Anthropic and OpenAI.
GLM-5.2 is open-weight, meaning developers can download its parameters and run it locally, modifying it as needed. This contrasts with many US frontier models, which remain proprietary. Since its debut, the model has garnered attention from prominent tech figures. Guillermo Rauch, CEO of Vercel, said on X that he was 'genuinely impressed, almost shocked' at its coding performance. Matt Velloso, former vice president at Meta and Google DeepMind, called it the 'first open model that passes the bar as a daily driver.'
Zhipu AI was founded in 2019 by Tang Jie and Li Juanzi, professors at Tsinghua University in Beijing. The company is considered part of China's 'AI tigers' and has strong government backing. It went public on the Hong Kong Stock Exchange in January 2026 under the name Knowledge Atlas Technology. Its chairman, Liu Debing, has amassed a fortune of $22.4 billion since the listing, according to Forbes.
The company previously released GLM-5 in February 2026 and GLM-5.1 in April. JPMorgan raised its 2026-2030 revenue forecast for Zhipu by 7 to 16 per cent following GLM-5.2's launch, projecting a 534 per cent revenue surge in 2026 and expecting profitability by 2028. On June 22, Zhipu's market capitalisation on the Hong Kong Stock Exchange briefly surpassed HK$1 trillion (US$128 billion), with shares rising up to 42 per cent.
While the model has generated significant interest, industry analysts caution that sustained adoption will depend on continued performance and ecosystem support. The development underscores the increasing competition between Chinese and US AI firms in the open-weight model space.
