§ 03 — COST

What GLM-5.3 costs in Australian dollars.

List prices converted at the snapshot’s RBA rate, excluding GST. Reasoning models are billed for their thinking as output tokens, so heavier settings cost more than the job estimates show.

§ 06 — QUESTIONS

GLM-5.3, answered.

GLM-5.3 lists at US$1.40 per million input tokens and US$4.40 per million output tokens — A$1.97 and A$6.18 at A$1 = US$0.7123 (RBA, 22 Sep 2026), excluding GST. A typical customer support reply works out at about A$5.78 per 1,000 replies, before any reasoning tokens.

GLM-5.3’s weights are public, so it can be hosted in Australia on your own infrastructure or an Australian cloud region. Availability comes from the cloud providers’ own documentation; check your provider’s current terms before relying on it for data-residency obligations.

It ranks 11th of 42 on our coding ranking, with an Artificial Analysis Coding Index of 74.8 and an LMArena WebDev rating of 1620 (14th of 129). The current leader is Claude Fable 5.1.

It ranks 8th of 41 on our agents ranking, completing 50.3% of τ²-Bench banking customer-service tasks and 83.9% of Terminal-Bench 2.1 tasks.

Artificial Analysis measures GLM-5.3 at about 63 tok/s of output, with the answer starting after 35 s on average once thinking time is included (max effort setting).

Z.ai documents a context window of 1,000,000 tokens (1M), with up to 128,000 output tokens. On AA-LCR, which tests reasoning across ~100,000-token document sets, it scores 79.7%.
