01 — Verdict

Too close to call

It is close. Our weighted score puts them within a point (Llama 3.3 Nemotron Super 49B v1.5 48/100, GLM-4.5-Air 48/100, GLM-4.7 41/100), so choose by what matters most for your work: Llama 3.3 Nemotron Super 49B v1.5 on price and GLM-4.7 for long inputs. 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.

04 — Questions

Which should you choose?

Which is better: Llama 3.3 Nemotron Super 49B v1.5, GLM-4.7 or GLM-4.5-Air?

It is close. Our weighted score puts them within a point (Llama 3.3 Nemotron Super 49B v1.5 48/100, GLM-4.5-Air 48/100, GLM-4.7 41/100), so choose by what matters most for your work: Llama 3.3 Nemotron Super 49B v1.5 on price and GLM-4.7 for long inputs. 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, Llama 3.3 Nemotron Super 49B v1.5, GLM-4.7 or GLM-4.5-Air?

Llama 3.3 Nemotron Super 49B v1.5 is cheaper at $0.40 input / $0.40 output per million tokens (median across 1 API provider). GLM-4.5-Air costs $0.20 input / $1.10 output per million tokens (official Z.AI API price); GLM-4.7 costs $0.60 input / $2.20 output per million tokens (official Z.AI API price). At a typical mix of three input tokens to one output token, that is $0.40 per million tokens for Llama 3.3 Nemotron Super 49B v1.5 versus $0.425 for GLM-4.5-Air (1.1× as much) and $1.00 for GLM-4.7 (2.5× as much).

Which scores higher on benchmarks?

There is no independent benchmark that covers all three models yet. Llama 3.3 Nemotron Super 49B v1.5 has not been scored yet, GLM-4.7 has an ECI of 143.7 and GLM-4.5-Air has not been scored yet.

Which is better for coding?

There are no published SWE-bench Verified results for Llama 3.3 Nemotron Super 49B v1.5, GLM-4.7 and GLM-4.5-Air yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. All three support tool calling for agent workflows.

Which has the bigger context window?

GLM-4.7 has the largest context window at 204,800 tokens, against 131,072 for Llama 3.3 Nemotron Super 49B v1.5 and 131,072 for GLM-4.5-Air. Maximum output per response: Llama 3.3 Nemotron Super 49B v1.5 up to 131,072, GLM-4.7 up to 131,072, GLM-4.5-Air up to 98,304 tokens.

Which can read images, PDFs, audio or video?

Llama 3.3 Nemotron Super 49B v1.5 accepts text; GLM-4.7 accepts text; GLM-4.5-Air accepts text. They handle the same number of input types.

Are any of these open source?

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

Which is newer?

GLM-4.7 is the newest, released Dec 22, 2025. GLM-4.5-Air came out Jul 28, 2025; Llama 3.3 Nemotron Super 49B v1.5 came out Jul 25, 2025. Knowledge cutoff: GLM-4.7 Apr 2025, 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 Nov 2, 2026.
