Why this status
Cited to official documentation and the official model card, and every value it asserts was found there. Modalities recorded as text-to-text. No image, audio or video capability appears anywhere in the primary sources, which labs advertise prominently when present. Licence from the model card's own license field on zai-org/GLM-5.1.
What these states mean · How records are judged · Has this record changed?

What changed from GLM-5
Compared with the previous release in this series. A field appears only when both records state a value — where one does not, it is listed as uncomparable rather than dropped, because a gap in our research is not a finding about the model.
Not comparable: Context window (not researched on both releases); Parameters (not researched on both releases)
