Too close to call
It is close. Our weighted score puts them within 3 points (Aya Expanse 32B 32/100, Hermes 3 405B Instruct 29/100, Aion-RP 1.0 (8B) 24/100), so choose by what matters most for your work: Aya Expanse 32B on price and Hermes 3 405B Instruct 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 should you choose?
Which is better: Aion-RP 1.0 (8B), Aya Expanse 32B or Hermes 3 405B Instruct?
It is close. Our weighted score puts them within 3 points (Aya Expanse 32B 32/100, Hermes 3 405B Instruct 29/100, Aion-RP 1.0 (8B) 24/100), so choose by what matters most for your work: Aya Expanse 32B on price and Hermes 3 405B Instruct 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, Aion-RP 1.0 (8B), Aya Expanse 32B or Hermes 3 405B Instruct?
Aya Expanse 32B is cheaper at $0.50 input / $1.50 output per million tokens (official Cohere API price).

At a typical mix of three input tokens to one output token, that is $0.75 per million tokens for Aya Expanse 32B versus $1.00 for Aion-RP 1.0 (8B) (1.3× as much) and $1.00 for Hermes 3 405B Instruct (1.3× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers all three models yet. Aion-RP 1.0 (8B) has not been scored yet, Aya Expanse 32B has not been scored yet and Hermes 3 405B Instruct has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for Aion-RP 1.0 (8B), Aya Expanse 32B and Hermes 3 405B Instruct 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), Aya Expanse 32B and Hermes 3 405B Instruct does not support tool calling, which most coding agents need.
Which has the bigger context window?
Hermes 3 405B Instruct has the largest context window at 131,072 tokens, against 128,000 for Aya Expanse 32B and 32,768 for Aion-RP 1.0 (8B). Maximum output per response: Aion-RP 1.0 (8B) up to 29,491, Aya Expanse 32B up to 4,000, Hermes 3 405B Instruct up to 16,384 tokens.
Which can read images, PDFs, audio or video?
Aion-RP 1.0 (8B) accepts text; Aya Expanse 32B accepts text; Hermes 3 405B Instruct accepts text. They handle the same number of input types.
Are any of these open source?
Yes, all three publish their weights (CC-BY-NC-4.0), so you can self-host them.
Which is newer?
Aion-RP 1.0 (8B) is the newest, released Feb 4, 2025. Aya Expanse 32B came out Oct 24, 2024; Hermes 3 405B Instruct came out Aug 16, 2024. Knowledge cutoff: Aion-RP 1.0 (8B) Dec 31, 2023, Hermes 3 405B Instruct Dec 31, 2023.
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.
