Z.ai comes from Zhipu AI, a Chinese AI lab founded in 2019 and considered one of the country's most established AI startups, predating the broader wave of Chinese AI labs that emerged after ChatGPT's 2022 launch. Its GLM model family powers the chat interface, developed through several generations of research since the company's founding.
That longer operating history relative to newer Chinese AI labs, several of which are also covered elsewhere in this category, gives Zhipu a more established research track record, though Z.ai carries less international brand recognition than more widely covered competitors like DeepSeek or Kimi despite the underlying company's comparable seniority.
Z.ai is free to use for standard chat. For anyone tracking the broader landscape of Chinese AI labs specifically, Z.ai represents one of the more established players by founding date, even if its consumer chat product hasn't reached the same international attention some newer competitors received.
