OpenAI-compatible API for Z.AI GLM models (Coding Endpoint).

Configuration

ZAI_API_KEY=your-api-key

Model Specs

For the full model-spec workflow, see Model Specs.

Use exact Z.AI Coder model IDs from LLMDB.xyz when possible. If you need to work ahead of the registry, use ReqLLM.model!/1.

Standard vs Coder Endpoints

This provider uses Z.AI's coding endpoint (/api/coding/paas/v4) optimized for:

  • Code generation
  • Technical tasks
  • Programming assistance

For general-purpose chat and reasoning, use the Z.AI Provider.

Implementation Notes

  • Extended timeout for thinking mode (300s)
  • Full OpenAI compatibility
  • Automatic thinking mode detection and timeout adjustment
