04 — Questions

Which should you choose?

Which is better: Nemotron Nano 9B v2 or GLM-4.5-Air?

Nemotron Nano 9B v2 is the better all-round choice, scoring 64/100 against GLM-4.5-Air (49). It leads on price. The score weighs price 50%, inputs & features 30%, context window 20%. None of the shared benchmarks cover every model here yet, so capability is left out of this verdict.

Which is cheaper, Nemotron Nano 9B v2 or GLM-4.5-Air?

Nemotron Nano 9B v2 is cheaper at $0.06 input / $0.23 output per million tokens (median across 3 API providers; free on Nvidia). GLM-4.5-Air costs $0.20 input / $1.10 output per million tokens (official Z.AI API price). At a typical mix of three input tokens to one output token, that is $0.102 per million tokens for Nemotron Nano 9B v2 versus $0.425 for GLM-4.5-Air (4.1× as much).

Which scores higher on benchmarks?

There is no independent benchmark that covers both models yet. Nemotron Nano 9B v2 has not been scored yet and GLM-4.5-Air has not been scored yet.

Which is better for coding?

There are no published SWE-bench Verified results for Nemotron Nano 9B v2 and GLM-4.5-Air yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. Both support tool calling for agent workflows.

Which has the bigger context window?

Nemotron Nano 9B v2 and GLM-4.5-Air share the same 131,072-token context window. Maximum output per response: Nemotron Nano 9B v2 up to 131,072, GLM-4.5-Air up to 98,304 tokens.

Which can read images, PDFs, audio or video?

Nemotron Nano 9B v2 accepts text; GLM-4.5-Air accepts text. They handle the same number of input types.

Are any of these open source?

Yes, both publish their weights, so you can self-host them.

Which is newer?

Nemotron Nano 9B v2 is the newest, released Aug 18, 2025. GLM-4.5-Air came out Jul 28, 2025. Knowledge cutoff: GLM-4.5-Air Apr 2025.

How do you decide the winner?

Each model gets a 0–100 score on capability (50%, independent benchmark results); price (25%, blended price per million tokens (3 input : 1 output), log scale); inputs & features (15%, image, PDF, audio and video input, tool calling, structured output and reasoning); context window (10%, maximum tokens per request, log scale). Dimensions missing for any model are dropped and the remaining weights rescaled, so every model is judged on the same evidence. Specs and prices come from public model listings and the labs’ own API pages; capability scores come from independent benchmark runs. Data updated Oct 4, 2026.
