When to pick Zhipu BigModel
Best for
- Full feature coverage — prompt caching, batch tier, function calling, fine-tuning.
- The lowest per-token rate for the maker's own models.
- Production workloads where a direct billing relationship matters.
Avoid for
- Multi-model workflows that need a unified billing surface.
- Anywhere the maker's own SLA isn't sufficient.
