In one line

A workhorse open-weight coder: SWE-bench Pro 62.1% and near the top of the React board on Code Arena. Superseded on raw capability by GLM-5.3-Flash, but still the lighter, cheaper option of the two to self-host.

Head-to-head: GLM-5.2 vs Kimi K3

Artificial Analysis Intelligence Index, 2026 rebased scale (top models ~ 55-66). Snapshot: September 4, 2026 (BenchLM mirror), retrieved September 8, 2026. Specs and prices come from the OpenRouter public model list on the same date. Models nobody has measured carry no index score at all and never enter a ranking: where an estimate exists it is shown separately and labelled unmeasured. Context, price, modality and release dates come from the public OpenRouter model list (retrieved September 8, 2026) and vendor pages. Missing values are not published or not yet verified - shown as -. Sources are linked inside the app (Model guide and About > Methodology).
