The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
Gigazine[5] (20 January 2026 JST) says Z.ai "released a lightweight AI model called GLM-4.7-Flash on January 19, 2026" and embeds Z.ai's X posts dated January 19, 2026; the Hugging Face repository was created and populated on 19 January. Some trackers show 20 January, a time-zone effect.
31.2B total and about 3B active parameters, benchmark table, single 24GB GPU or Apple Silicon deployment, free API and 1.7M downloads in the first month.[1]
Z.ai's GLM-4.7 guide lists GLM-4.7-Flash ("Lightweight, Completely Free") and GLM-4.7-FlashX ("Lightweight, High-Speed, and Affordable") with 200K context and 128K maximum output, and says Flash reaches open-source SOTA among comparable sizes on SWE-bench Verified and τ²-Bench.[1]
Z.ai's pricing page: GLM-4.7-Flash free; GLM-4.7-FlashX $0.07 input, $0.01 cached and $0.4 output per million tokens.[1]
GIGAZINE reports the release on January 19, 2026, embeds Z.ai's announcement posts of that date, the corrected BrowseComp chart and the BF16 45GB VRAM requirement; MIT licence.
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
