kimi-k2.6 vs zai-glm-4.7

Capability for the money

kimi-k2.6 is 1.4× cheaper than zai-glm-4.7 and scores higher on following instructions (IFBench) and hard reasoning (GPQA Diamond) — there is no case for paying more here.

Averaged over the benchmarks both models sat, kimi-k2.6 returns 51.2 points of pass rate per dollar of blended price against 35.0 — the ratio that decides whether the dearer model earns its rate.

Each figure is a pass rate: the share of that test set the model answered correctly, measured by a third party rather than self-reported by the lab. Rows are different tests of different difficulty, so compare a model against the other model, not one row against the next. No published coding score for one of these models, so that lens is omitted. And a benchmark is not your workload — it narrows the shortlist, it does not pick for you.
