GLM 5.2 is our best model for coding right now, with a 400K context window for large codebases. Vision is available on the Anthropic Messages API (`/v1/messages`) only, through a server-side handoff (GLM 5.2 generates the text, Kimi preprocesses the image); that handoff will be retired soon in favour of more efficient client-side image handling.

Events for Umans GLM 5.2
Jul 102026
Resolved: Umans GLM 5.2 Resolved
The incident is resolved. Throughout the outage, most requests continued to be served, and a subset of users were affected. Umans GLM 5.2 is still running at reduced capacity, so responses may be slower than usual at peak times. We will post an update once full capacity is restored.

Major outage: Umans GLM 5.2 Incident
We are currently experiencing a major outage affecting Umans GLM 5.2. Other models are unaffected. Our team is fully mobilized and working to restore normal operation as quickly as possible. We will post updates here as the situation evolves.

GLM 5.2 performance stabilized, still on reduced capacity Resolved
GLM 5.2 performance has stabilized after deploying the prefill kernel update and selective prioritization for interactive requests.
We’re still operating today in reduced-capacity mode while capacity is being restored, but the service is holding and requests are flowing normally. We’ll keep monitoring closely and update here if anything changes.
Jul 92026
Degraded performance on Umans GLM 5.2 Incident
We’re currently seeing degraded performance on Umans GLM 5.2, mainly higher time-to-first-token and uneven streaming speed.
Requests are still going through, but the experience can feel slower than usual.
We’re investigating and applying mitigations. We’ll update here once things are back to target.

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.
Jul 22026
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.

Released to production: Umans GLM 5.2 Released
umans-glm-5.2 was released as the long-context model, with a 405K context window, after a pre-release period that started Jun 16.
