Zhipu AI Stock Rockets 30% After Dropping Open-Source GLM-5

Chinese AI firm Zhipu AI sees massive stock surge following release of its latest open-source model with beefed-up coding chops.

Zhipu AI Stock Rockets 30% After Dropping Open-Source GLM-5

Zhipu AI just had a very good Thursday. The Hong Kong-listed company watched its stock jump 30% after unveiling GLM-5, its newest open-source large language model.

The model brings upgraded coding capabilities and can handle long-running agent tasks — the kind of persistent, multi-step operations that separate toy demos from actually useful AI tools.

The timing wasn't coincidental. Chinese AI stocks broadly rallied as multiple companies dropped upgraded models while government policymakers pushed for wider AI adoption across the country.

Open-source AI continues to heat up globally, and Chinese players are making their presence felt. Zhipu's stock pop suggests investors are betting the company's approach — giving away the model while building around it — might just pay off.
