Chinese AI startup Z.ai has introduced GLM-5-Turbo, a proprietary variant of its GLM-5 model, optimized for agent-driven workflows like tool use and automation. The model is available through Z.ai's API on OpenRouter with a context window of 202.8K tokens and pricing set at $0.96 per million input tokens.

It is integrated into Z.ai's GLM Coding subscription service, with Pro subscribers gaining access in March 2026. GLM-5-Turbo is designed for fast inference and improved task execution, and has a lower tool call error rate than its predecessor. However, it is currently closed-source, indicating a potential shift in Z.ai's strategy in the competitive Chinese AI market.
