Zhipu, one of China's leading AI companies, has raised prices on its GLM-4 large language model by at least 8% across input and output tokens, marking the second significant price hike in recent months. The increase affects both enterprise and developer-tier users, with input token costs rising to approximately 0.15 yuan per 1,000 tokens and output tokens to 0.6 yuan per 1,000 tokens. Zhipu's pricing adjustments arrive as the company seeks to monetize its foundational AI research and substantial computing infrastructure investments accumulated over years of development. The company has justified the increases by citing improved model performance and capability enhancements, a rationale shared by other major Chinese AI providers including Baidu and Alibaba, who have similarly hiked prices in recent quarters. Industry analysts suggest that Chinese API providers face less price sensitivity from their domestic developer base compared to Western markets, where competition from open-source models and free tier offerings remains more aggressive. The moves indicate that Chinese firms are prioritizing margin expansion over market share growth, betting that enterprise customers and integrated platform operators will absorb cost increases.
