Details

Z.ai's GLM 5.1 is now available on Vercel AI Gateway.

This model is designed for long-running autonomous tasks, handling planning, execution, testing, and iterative refinement in a closed loop while continuing a single task. It excels at finding and optimizing bottlenecks through multiple iterations rather than one-shot code generation.

Key use cases include the following.

  • agentic coding and ongoing multistep engineering workflows
  • general conversation, creative writing, and frontend prototyping
  • office productivity tasks such as generating PowerPoint, Word, and Excel documents

To use it, set the model to zai/glm-5.1 in the AI SDK. Vercel AI Gateway provides a unified API for model calls, bundling usage and cost tracking, retries and failover, performance optimization, custom reporting, observability, Bring Your Own Key support, and automatic provider routing.
