Frequently asked questions
How much does it cost to use Z.ai: GLM 5.3?
Z.ai: GLM 5.3 is a Pro model: it costs 31 tokens per use (~$0.15 real cost for us). You need a Pro plan ($9/month → 15,000 tokens) or a one-shot pack. If you already have tokens in the free account, you can also spend them directly.
How many uses of Z.ai: GLM 5.3 are included in the Pro plan?
Pro ($9/month) gives you 15,000 recurring tokens. At 31 tokens per use of Z.ai: GLM 5.3, that's ~483 full uses per cycle. If you run out, one-shot packs (5,000 / 25,000 / 80,000 tokens) add to the balance without expiring before one year.
What makes Z.ai: GLM 5.3 special?
Its specific strengths are: advanced complex reasoning, 1m token context and specialized software engineering.
How fast does Z.ai: GLM 5.3 respond?
Z.ai: GLM 5.3 has a balanced speed: 5-15 seconds per response — neither the fastest nor the slowest in the catalog. The actual time also depends on the length of the prompt and the load of the datacenter — models with huge context take longer when you enter very long texts.
