Gemini 3.6 Flash 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

Effectively the same quality — Gemini 3.6 Flash is the cheaper way to get it.

The two are within 0.4 points overall, which is inside the range that effort settings alone move a LiveBench score, so treat them as quality-equivalent. Gemini 3.6 Flash lists 2.0× cheaper per blended million tokens. When quality ties, cost is the whole decision.

Gemini 3.6 Flash vs GLM 5.2 FAQ

Which is better, Gemini 3.6 Flash or GLM 5.2?

Effectively the same quality — Gemini 3.6 Flash is the cheaper way to get it. The two are within 0.4 points overall, which is inside the range that effort settings alone move a LiveBench score, so treat them as quality-equivalent. Gemini 3.6 Flash lists 2.0× cheaper per blended million tokens. When quality ties, cost is the whole decision.

Is Gemini 3.6 Flash cheaper than GLM 5.2?

Gemini 3.6 Flash is cheaper. On a 3:1 input:output blend, Gemini 3.6 Flash lists at $1.50 per million tokens and GLM 5.2 at $3.03 — Gemini 3.6 Flash is 2.0× cheaper. Input and output are priced separately — Gemini 3.6 Flash charges $0.750 in and $3.75 out, GLM 5.2 charges $0.046 and $12.00 — so the model that looks cheaper flips depending on how output-heavy your workload is.

Gemini 3.6 Flash vs GLM 5.2: which scores higher on benchmarks?

Gemini 3.6 Flash scores 73.6 and GLM 5.2 scores 73.2 overall on LiveBench, the mean of its seven categories. That gap is inside the range that effort settings alone move a score, so treat them as equivalent on published quality. 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, Gemini 3.6 Flash or GLM 5.2?

They are close. Gemini 3.6 Flash costs $0.1327 per point of overall capability and GLM 5.2 costs $0.1260, a difference small enough that workload shape will matter more than the rate.

Does Gemini 3.6 Flash or GLM 5.2 have a bigger context window?

They are effectively the same — 1.0M for Gemini 3.6 Flash and 1.0M for GLM 5.2.

Do Gemini 3.6 Flash and GLM 5.2 support prompt caching?

Both publish a cached-input rate: $0.075 per million for Gemini 3.6 Flash and $0.046 for GLM 5.2, against full input rates of $0.750 and $0.046. 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.
  • Scores — LiveBench 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.
