Artificial Analysis observed and listed GLM-5.3 (max) in its model catalog on 18 August 2026, scoring 60 on the AA Intelligence Index. This is an observation from an independent evaluator, not a vendor announcement — the model's creator label as AA lists it is 'Z AI'.
The ID z-ai/glm-5.3 showed up in OpenRouter's public model-list API on 2026-08-21, listed at 1,048,576 context. Catalog observation only — no Z.ai announcement was checked, and the entry could be a test or placeholder.
