Events for Umans GLM 5.2 NVFP4
Jul 62026
Resolved: back to full capacity Resolved
Hardware capacity was restored and both umans-glm-5.2 and umans-kimi-k2.7 are back to normal speed. During the outage the service ran in a reduced-capacity mode that favoured continuity over speed: requests kept flowing, at the cost of an uneven experience. The affected window is shaded on each model's speed trends.

Incident: hardware outage, running at reduced capacity Incident
A hardware failure took part of our GPU fleet offline. We failed over to reduced capacity to keep the service available: umans-glm-5.2 and umans-kimi-k2.7 stayed up, but slower than usual and with an uneven experience under load. Live updates were posted on Discord throughout.
