Browse by need
Z.ai ships the GLM family: GLM 5.3 at $1.40 input and $4.40 output, the Flash variant at $0.075 and $0.25, and earlier generations still in service. Context windows run to 1.31M tokens on the Flash line — larger than most Western flagships.
The appeal is the ratio. GLM 5.3 competes on reasoning and coding benchmarks with models priced several times higher, and the weights are downloadable, so the hosted price is a convenience rather than a lock-in. For cost-sensitive production work this is one of the strongest value positions in the rating.
Models from this vendor
12 Z.ai models in this rating. Prices are input and output per 1M tokens from the vendor official price list; for dirhams multiply by 3.6725. Tap a card to open the model page.
How to choose
- Benchmark GLM 5.3 against models three times its price before assuming you need them.
- Use the Flash variant for volume — it holds a 1.31M window at $0.25 output.
- Plan for self-hosting if volume grows, since the weights are published.
- Check third-party hosting options if you need a non-Chinese endpoint.
