Inkling 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

GLM 5.2 wins outright — it scores higher and costs less.

GLM 5.2 leads by 1.2 points overall while listing 16% cheaper per blended million tokens. There is no trade-off to reason about here; the only reason to pick the other is a constraint this table does not show, like an existing contract, a region, or a provider you are already on. GLM 5.2 also leads on measured cost per point of capability, at $0.1260 per point.

What each one costs to run

Per-token prices are hard to feel. These are monthly list costs for both models across five workload shapes, using each provider's published cached-input rate where there is one.

Inkling vs GLM 5.2 FAQ

Which is better, Inkling or GLM 5.2?

GLM 5.2 wins outright — it scores higher and costs less. GLM 5.2 leads by 1.2 points overall while listing 16% cheaper per blended million tokens. There is no trade-off to reason about here; the only reason to pick the other is a constraint this table does not show, like an existing contract, a region, or a provider you are already on. GLM 5.2 also leads on measured cost per point of capability, at $0.1260 per point.

Is Inkling cheaper than GLM 5.2?

GLM 5.2 is cheaper. On a 3:1 input:output blend, Inkling lists at $1.72 per million tokens and GLM 5.2 at $1.48 — GLM 5.2 is 16% cheaper. Input and output are priced separately — Inkling charges $0.950 in and $4.05 out, GLM 5.2 charges $0.966 and $3.04 — so the model that looks cheaper flips depending on how output-heavy your workload is.

Inkling vs GLM 5.2: which scores higher on benchmarks?

Inkling scores 71.9 and GLM 5.2 scores 73.2 overall on LiveBench, the mean of its seven categories. That is a 1.2-point lead for GLM 5.2. Category scores differ from the overall figure — a model can lead on reasoning and trail on coding, which the per-category table above breaks out.

Which gives better value for money, Inkling or GLM 5.2?

GLM 5.2. Cost per point divides the measured dollars LiveBench spent running the benchmark by the score it earned, so it captures something token pricing misses: a reasoning model can emit many times more tokens than its per-token rate suggests. Inkling works out at $0.1766 per point and GLM 5.2 at $0.1260.

Does Inkling or GLM 5.2 have a bigger context window?

They are effectively the same — 1.0M for Inkling and 1.0M for GLM 5.2.

Do Inkling and GLM 5.2 support prompt caching?

Both publish a cached-input rate: $0.160 per million for Inkling and $0.193 for GLM 5.2, against full input rates of $0.950 and $0.966. 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.
