GLM-5

Z.ai
GLM-5 moves Z.ai’s line into a new foundation class with 744B total parameters, 40B active parameters, and 200K tokens of context. Compared with GLM-4.7, Z.ai describes the larger base and stable tool use across many steps as a generational change. The weights remain openly available.
Z.ai provides the checkpoint through an API and open weights. GLM-5.1 is the direct follow-up and focuses on greater stability for long tasks.
The index averages rank percentiles from 10 documented comparison cohorts.

One SVG prompt and fixed output settings. Captures are shown only with 0 reported reasoning tokens or documented lack of reasoning controls. Identical test conditions do not make the models' internal compute identical.

A community classic for free-form SVG drawing.

The response reached the token limit. No complete recording is available.
Reasoning (requested): high
Not yet visually reviewed. A successful recording does not confirm correct physics or full compliance with the prompt.

Previous generation in the directory
Z.ai calls GLM-5 a new-generation foundation model, documents its larger 744B base against the prior 355B base, and reports gains over GLM-4.7. The provider does not call this pair a formal adjacent replacement, so it remains a nearest-profile relation.
Z.ai Developer Docs, GLM-5 overview (2026-09-22)Z.ai's own release-notes index describes GLM-5.1 as designed for long-horizon tasks that 'further improves stability' over GLM-5, listed as the next entry after GLM-5.
