04 — Questions

Which should you choose?

Which is better: GLM-4.5 or Apertus 70B?

GLM-4.5 is the better all-round choice, scoring 40/100 against Apertus 70B (33). It leads on price, inputs & features and context window. 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, GLM-4.5 or Apertus 70B?

GLM-4.5 is cheaper at $0.60 input / $2.20 output per million tokens (official Z.AI API price). Apertus 70B costs $0.82 input / $2.42 output per million tokens (median across 3 API providers). At a typical mix of three input tokens to one output token, that is $1.00 per million tokens for GLM-4.5 versus $1.22 for Apertus 70B (1.2× as much).

Which scores higher on benchmarks?

There is no independent benchmark that covers both models yet. GLM-4.5 has not been scored yet and Apertus 70B has not been scored yet.

Which is better for coding?

There are no published SWE-bench Verified results for GLM-4.5 and Apertus 70B 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?

GLM-4.5 has the largest context window at 131,072 tokens, against 65,536 for Apertus 70B. Maximum output per response: GLM-4.5 up to 98,304, Apertus 70B up to 8,192 tokens.

Which can read images, PDFs, audio or video?

GLM-4.5 accepts text; Apertus 70B accepts text. They handle the same number of input types.

Are any of these open source?

Yes, both publish their weights (Apache-2.0), so you can self-host them.

Which is newer?

Apertus 70B is the newest, released Sep 2, 2025. GLM-4.5 came out Jul 28, 2025. Knowledge cutoff: GLM-4.5 Apr 2025, Apertus 70B Sep 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.
