Choosing a Model

• GLM-5 is the flagship with reasoning -- Arena score 1449 puts it in the top tier globally.
• GLM 4.7 Flash offers reasoning at just $0.06/MTok input -- excellent value for chain-of-thought tasks.
• GLM-4 Flash is free and good for simple tasks, experimentation, or budget-conscious workflows.

Reasoning Support

GLM-5, GLM 4.7, GLM 4.7 Flash, and GLM 4.6 all support reasoning mode. When enabled, the model thinks through problems step by step before delivering its answer, similar to extended thinking in other providers.

Also Available on OpenRouter

Several GLM models are accessible via OpenRouter without a Zhipu account:

• z-ai/glm-5 -- GLM-5 745B
• z-ai/glm-4.7 -- GLM 4.7
• z-ai/glm-4.5-air:free -- GLM 4.5 Air (free)

Configuration

Select Zhipu AI as the provider when creating a bot profile. The app connects to open.bigmodel.cn using the OpenAI-compatible format with Bearer authentication.

Tips for Best Results

• GLM-5 is a strong contender for reasoning tasks. Its Arena score places it near the top -- try it for complex analysis alongside Claude and GPT.
• Use GLM-4 Flash for free experimentation. Test prompts and workflows at zero cost before scaling up to paid models.
• GLM models handle Chinese text natively. For bilingual or Chinese-focused applications, GLM is a natural fit.
