01 — Verdict

Too close to call

It is close. Our weighted score puts them within 2 points (Granite-4.0-H-Small 63/100, GLM-4.7-FlashX 61/100, Apertus 8B 56/100), so choose by what matters most for your work: Granite-4.0-H-Small on price and GLM-4.7-FlashX 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: Apertus 8B, GLM-4.7-FlashX or Granite-4.0-H-Small?

It is close. Our weighted score puts them within 2 points (Granite-4.0-H-Small 63/100, GLM-4.7-FlashX 61/100, Apertus 8B 56/100), so choose by what matters most for your work: Granite-4.0-H-Small on price and GLM-4.7-FlashX 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, Apertus 8B, GLM-4.7-FlashX or Granite-4.0-H-Small?

Granite-4.0-H-Small is cheaper at $0.064 input / $0.265 output per million tokens (official watsonx.ai API price). Apertus 8B costs $0.10 input / $0.20 output per million tokens (median across 1 API provider); GLM-4.7-FlashX costs $0.07 input / $0.40 output per million tokens (official Z.AI API price). At a typical mix of three input tokens to one output token, that is $0.114 per million tokens for Granite-4.0-H-Small versus $0.125 for Apertus 8B (1.1× as much) and $0.152 for GLM-4.7-FlashX (1.3× as much).

Which scores higher on benchmarks?

There is no independent benchmark that covers all three models yet. Apertus 8B has not been scored yet, GLM-4.7-FlashX has not been scored yet and Granite-4.0-H-Small has not been scored yet.

Which is better for coding?

There are no published SWE-bench Verified results for Apertus 8B, GLM-4.7-FlashX and Granite-4.0-H-Small 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-FlashX has the largest context window at 200,000 tokens, against 131,072 for Granite-4.0-H-Small and 65,536 for Apertus 8B. Maximum output per response: Apertus 8B up to 8,192, GLM-4.7-FlashX up to 131,072, Granite-4.0-H-Small up to 131,072 tokens.

Which can read images, PDFs, audio or video?

Apertus 8B accepts text; GLM-4.7-FlashX accepts text; Granite-4.0-H-Small accepts text. They handle the same number of input types.

Are any of these open source?

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

Which is newer?

GLM-4.7-FlashX is the newest, released Jan 19, 2026. Granite-4.0-H-Small came out Oct 2, 2025; Apertus 8B came out Sep 2, 2025. Knowledge cutoff: Apertus 8B Sep 2025, GLM-4.7-FlashX 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.
