Sources

Record status: partly verified · confidence 80/100 · 2 of 2 primary

Cited to the lab's own announcement and the official model card. Not verified because the context window could not be found in any cited primary source — the value may be correct, but this dataset cannot yet show where it came from.

Primary means published by the organisation that made the model. Verified records require at least one.

What changed from GLM-4

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: Parameters (not researched on both releases); Capabilities and modalities (not researched on both releases)
