GPT-4.1 Mini vs GLM 5.3
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.
GPT-4.1 Mini is the cheaper of the two; neither can be ranked on quality here.
GPT-4.1 Mini 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.

Benchmarks by category
An overall score averages away the thing you probably care about. These are the seven LiveBench categories scored separately — GPT-4.1 Mini on top, GLM 5.3 below, both out of 100.
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-4.1 Mini vs GLM 5.3 FAQ
Which is better, GPT-4.1 Mini or GLM 5.3?
GPT-4.1 Mini is the cheaper of the two; neither can be ranked on quality here. GPT-4.1 Mini 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-4.1 Mini cheaper than GLM 5.3?
GPT-4.1 Mini is cheaper. On a 3:1 input:output blend, GPT-4.1 Mini lists at $0.700 per million tokens and GLM 5.3 at $1.29 — GPT-4.1 Mini is 1.8× cheaper. Input and output are priced separately — GPT-4.1 Mini charges $0.400 in and $1.60 out, GLM 5.3 charges $0.840 and $2.64 — so the model that looks cheaper flips depending on how output-heavy your workload is.
Does GPT-4.1 Mini or GLM 5.3 have a bigger context window?
GLM 5.3 has the larger context window: 1.0M for GPT-4.1 Mini against 1.3M for GLM 5.3. 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-4.1 Mini and GLM 5.3 support prompt caching?
Both publish a cached-input rate: $0.100 per million for GPT-4.1 Mini and $0.156 for GLM 5.3, against full input rates of $0.400 and $0.840. 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.
Published benchmarks rank models on someone else's tasks. Before committing, see LLM & agent evaluation for building an eval on your own.
