Zhipu challenges OpenAI with upcoming GLM-4.5 open-source model, launch likely next week

Zhipu, a Chinese artificial intelligence firm now rebranded as Z.ai, is reportedly preparing to launch the latest version of its open-source language model, GLM-4.5, early next week. The move places it among a rising number of Chinese tech companies accelerating their efforts to make advanced AI models freely accessible.

According to a Bloomberg report, the release of the LLM model is expected as soon as Monday. GLM-4.5 will serve as an upgrade to the firm’s existing flagship model, as Zhipu attempts to position itself as a serious contender in the global AI landscape.
