DeepSeek vs GLM (Z.AI)
As of 2026-11-04.
DeepSeek operates a dedicated international-friendly API at api.deepseek.com with published peak/off-peak USD rates. Zhipu’s GLM models are offered to international users primarily through Z.AI with pricing documented at docs.z.ai.
Practical differences
- Docs surface: DeepSeek API docs vs Z.AI docs (avoid mixing with China-only BigModel CN pricing).
- Open weights: DeepSeek V4 MIT releases are clearly labeled; GLM open releases are version-specific — check each LICENSE.
- Concurrency: DeepSeek publishes concurrency numbers on the pricing page (e.g. Flash vs Pro limits); confirm GLM limits in Z.AI docs/account.
