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.
Gemini 3.6 Flash and GLM 5.2 are close on both score and price.
Neither model separates itself on published score or list price. Pick on the things this table cannot measure: latency under your load, context window headroom, tool-calling reliability, and whichever provider you already have a contract with.

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.

Gemini 3.6 Flash vs GLM 5.2 FAQ
Which is better, Gemini 3.6 Flash or GLM 5.2?
Gemini 3.6 Flash and GLM 5.2 are close on both score and price. Neither model separates itself on published score or list price. Pick on the things this table cannot measure: latency under your load, context window headroom, tool-calling reliability, and whichever provider you already have a contract with.
Is Gemini 3.6 Flash cheaper than GLM 5.2?
They cost about the same. Both land near $1.50 per million tokens on a 3:1 input:output blend, so price is unlikely to be the deciding factor between them.
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 $0.193 for GLM 5.2, against full input rates of $0.750 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.
- 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.
