01 — Verdict

GLM-4.5V is our pick

GLM-4.5V is the better all-round choice, scoring 48/100 against Aion-RP 1.0 (8B) (24). 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.

04 — Questions

Which should you choose?

Which is better: Aion-RP 1.0 (8B) or GLM-4.5V?

GLM-4.5V is the better all-round choice, scoring 48/100 against Aion-RP 1.0 (8B) (24). 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, Aion-RP 1.0 (8B) or GLM-4.5V?

GLM-4.5V is cheaper at $0.60 input / $1.80 output per million tokens (official Z.AI API price). Aion-RP 1.0 (8B) costs $0.80 input / $1.60 output per million tokens (median across 4 API providers). At a typical mix of three input tokens to one output token, that is $0.90 per million tokens for GLM-4.5V versus $1.00 for Aion-RP 1.0 (8B) (1.1× as much).

Which scores higher on benchmarks?

There is no independent benchmark that covers both models yet. Aion-RP 1.0 (8B) has not been scored yet and GLM-4.5V has not been scored yet.

Which is better for coding?

There are no published SWE-bench Verified results for Aion-RP 1.0 (8B) and GLM-4.5V yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. Note that Aion-RP 1.0 (8B) does not support tool calling, which most coding agents need.

Which has the bigger context window?

GLM-4.5V has the largest context window at 64,000 tokens, against 32,768 for Aion-RP 1.0 (8B). Maximum output per response: Aion-RP 1.0 (8B) up to 29,491, GLM-4.5V up to 16,384 tokens.

Which can read images, PDFs, audio or video?

Aion-RP 1.0 (8B) accepts text; GLM-4.5V accepts text, images and video. GLM-4.5V handles the widest range of inputs.

Are any of these open source?

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

Which is newer?

GLM-4.5V is the newest, released Aug 11, 2025. Aion-RP 1.0 (8B) came out Feb 4, 2025. Knowledge cutoff: Aion-RP 1.0 (8B) Dec 31, 2023, GLM-4.5V 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.
