GLM-5.3
Z.ai's strongest coding model, with open weights, a 1M-token window and 128K output. Text input only. Z.ai reports a 50% gain over GLM-5.2 on its own code benchmark.
Model ID: glm-5.3
What that means
A worked example
Per-token pricing is hard to feel. Take a moderately chatty production workload: 100 calls a day, roughly 10,000 tokens in and 2,000 out each time. On GLM-5.3 that comes to about:
$68 / month
Before caching, batching or volume discounts, all of which move this number a long way. Illustrative only.
