GLM 5.3 is a language model from Z.ai with a 1M-token context window. Provider list price is $1.40 per million input tokens and $4.40 per million output; on Allocate you pay $1.50 and $4.71. The weights are open, so you can fine-tune it and own the result.
What a real workload costs
Take 1,000,000 requests a month at 1,200 input and 350 output tokens each: 1,200M input and 350M output tokens. At list prices that is 1,200 × $1.40 + 350 × $4.40 = $3,220 a month. Billed on Allocate it is $3,445.

Yes. GLM 5.3 is an open-weights model; check the lab’s model card for the exact license terms. Read the license terms before fine-tuning for commercial use. On Allocate the trained weights stay inside your boundary and belong to you.
Has the price of GLM 5.3 changed?
Allocate has checked the provider list price hourly since 12 Sep 2026. It has not changed in that time. The price history chart on this page shows every change.
How do I call GLM 5.3 on Allocate?
