Chinese AI stocks rallied sharply Friday, extending gains as new model releases from Zhipu and Minimax boosted market sentiment. Knowledge Atlas Tech Joint Stock surged over 20% to HK$492.0 after introducing GLM-5, an open-source large-language model comparable to Anthropic's Claude Opus 4.5 in coding tests.

Zhipu raised subscription prices for its GLM coding plan by as much as 30%, citing surging demand. Peer MiniMax Group jumped over 15% to HK$688.0 following its updated M2.5 open-source AI model launch with enhanced agentic tools. Both companies are among China's "AI Tigers" and have performed strongly since their late-2025 listings.

The broader AI sector gained momentum, with chipmaker Shanghai Iluvatar CoreX SemiCon rising over 12%. These stocks largely avoided a broader tech sector decline, demonstrating investor confidence in China's AI advancements despite broader market weakness.
