Why moderate: inherited from z-ai/glm-5.2: a serving variant shares its base model's tokenizer.
This entry is a serving variant of Z.ai: GLM 5.2. A variant shares its base model's tokenizer by construction, so the measurement lives on the base record and this page inherits it.
Z.ai: GLM 5.2 (batch) is Z.ai's model, and its measured tokenizer sits in Z.ai's own signature group alongside its sibling models. No other maker's measured model shares it so far.

GLM 5.2 is a large-scale reasoning model from Z.ai. It supports text input and output with a 1M-token context window, and is suited for long-horizon agent workflows, project-level software engineering,...

* Z.ai: GLM 5.2 (batch) no longer appears in the OpenRouter catalogue, first absent from the snapshot of 5 October 2026. The record stays because the measurements above were real when they were taken and this address has been published.
