Kimi K2.5 vs GLM 5.2

Published LiveBench scores across all seven categories, live list pricing, context windows, and the measured cost of a point of capability — for both models, side by side.

OpenRouter + LiveBenchAll comparisonsFull leaderboard

Kimi K2.5 is the cheaper of the two; neither can be ranked on quality here.

Kimi K2.5 does not have a published LiveBench run, so this comparison covers price, context and declared capabilities only. A missing score means "not evaluated", not "worse" — the right way to separate these two is an eval on your own workload.

Kimi K2.5 vs GLM 5.2 FAQ

Which is better, Kimi K2.5 or GLM 5.2?

Kimi K2.5 is the cheaper of the two; neither can be ranked on quality here. Kimi K2.5 does not have a published LiveBench run, so this comparison covers price, context and declared capabilities only. A missing score means "not evaluated", not "worse" — the right way to separate these two is an eval on your own workload.

Is Kimi K2.5 cheaper than GLM 5.2?

Kimi K2.5 is cheaper. On a 3:1 input:output blend, Kimi K2.5 lists at $0.900 per million tokens and GLM 5.2 at $0.998 — Kimi K2.5 is 11% cheaper. Input and output are priced separately — Kimi K2.5 charges $0.450 in and $2.25 out, GLM 5.2 charges $0.650 and $2.04 — so the model that looks cheaper flips depending on how output-heavy your workload is.

Does Kimi K2.5 or GLM 5.2 have a bigger context window?

GLM 5.2 has the larger context window: 262K for Kimi K2.5 against 1.0M for GLM 5.2. Note that a window you can fill is not a window you should fill — retrieval quality usually degrades well before the limit, and you pay for every token you put in it.

Do Kimi K2.5 and GLM 5.2 support prompt caching?

Both publish a cached-input rate: $0.070 per million for Kimi K2.5 and $0.121 for GLM 5.2, against full input rates of $0.450 and $0.650. On a workload with a long stable prefix — a system prompt, a tool schema, a retrieved corpus — that changes the economics more than the headline price does.

How these numbers are produced

  • Price — provider list price from OpenRouter, refreshed every 15 minutes. “Blended” is a 3:1 input:output mix.
  • ScoresLiveBench release 2026-06-25, using their own category map. Each model shows its strongest published run. A blank means “not evaluated”, never “bad”.
  • Cost per point — the measured dollars LiveBench spent on the run, divided by the score it earned.
  • “Win” — awarded only past a threshold: one full point on a benchmark score, 10% on a price, 25% on a context window. Anything tighter reports as a tie, because effort settings alone move a LiveBench score by more than that.
