Zhipu AI’s stock rockets after Chinese firm makes GLM-5.2 open source

Move underscores a trend of Chinese players seeking to capture users displaced by rising prices for top models from US rivals

The Hong Kong-listed stock surged as much as 48 per cent to HK$1,620 in morning trading, before retreating to HK$1,404 at the noon break.

Zhipu AI announced on Saturday the full release of GLM-5.2, featuring a massive 1-million-token context window.

The launch underscores a trend of Chinese players seeking to capture users displaced by higher-priced Western alternatives.

Users can access the model through the new GLM Coding Plan subscription, which is priced at just a tenth as much as Anthropic’s premium Claude Code and Claude Max tiers.
