GLM-5.3 API pricing in Australia
In Australian dollars, the currency your card is charged in, with the published US dollar rate beside each.
For scale: 1,000 requests of about 3,000 tokens in and 1,000 out cost A$11.50 — a long prompt and a page of answer each. Every rate is published and stays the same from one request to the next. See every model.
Prices are our published US dollar rates converted at A$1.47 to the dollar, our rate for October — the same rate your card is charged.
About GLM-5.3
GLM-5.3 is Z.ai’s top model, and an unusual kind of upgrade: the base model is the same as GLM-5.2, and every gain came from further training on top of it. The gains are large where Z.ai aimed them — 66.9% on DeepSWE, up from 46.2%, and 84.5% on the CyberGym security benchmark, which Z.ai puts ahead of Claude Fable 5.
It always thinks before answering, at low, high or max effort (max is the default), and handles a million-token context. The weights are open under Z.ai’s own licence, which asks the very largest companies to pass a security review first.
What is GLM-5.3 good for?
- Long coding agents that work through a large change.
- Security analysis and defensive cyber work.
- Command-line automation agents.
Where to be careful
- Every call reasons — there is no fast mode — so simple requests are slower and dearer than they need to be.
- Z.ai’s headline coding gain is on a private benchmark whose method is not published.
- Text only.
