GPT-5.6 Sol vs GLM 5V Turbo
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.
GLM 5V Turbo is the cheaper of the two; neither can be ranked on quality here.
GLM 5V Turbo 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.

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.

GPT-5.6 Sol vs GLM 5V Turbo FAQ
Which is better, GPT-5.6 Sol or GLM 5V Turbo?
GLM 5V Turbo is the cheaper of the two; neither can be ranked on quality here. GLM 5V Turbo 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 GPT-5.6 Sol cheaper than GLM 5V Turbo?
GLM 5V Turbo is cheaper. On a 3:1 input:output blend, GPT-5.6 Sol lists at $4.00 per million tokens and GLM 5V Turbo at $1.90 — GLM 5V Turbo is 2.1× cheaper. Input and output are priced separately — GPT-5.6 Sol charges $2.00 in and $10.00 out, GLM 5V Turbo charges $1.20 and $4.00 — so the model that looks cheaper flips depending on how output-heavy your workload is.
Does GPT-5.6 Sol or GLM 5V Turbo have a bigger context window?
GPT-5.6 Sol has the larger context window: 1.1M for GPT-5.6 Sol against 203K for GLM 5V Turbo. 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 GPT-5.6 Sol and GLM 5V Turbo support prompt caching?
Both publish a cached-input rate: $0.200 per million for GPT-5.6 Sol and $0.240 for GLM 5V Turbo, against full input rates of $2.00 and $1.20. 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.
