What you need to know about Aion-RP 1.0 (8B)
AionLabs put Aion-RP 1.0 (8B) online on February 4, 2025. It accepts text as input and produces text. Its context window reaches 32,768 tokens, larger than 8 % of the models in the registry, and it can write up to 29,491 tokens in one go.
Released more than 1 year ago, it belongs to a generation most vendors have since superseded.
Aion-RP 1.0 (8B) pricing
On OpenRouter, Aion-RP 1.0 (8B) costs $0.8 per million input tokens and $1.6 per million output tokens. Counting three tokens read for every token written, its average price is $1 per million, more expensive than 59 % of paid models (1.3 times the median of $0.76).
A concrete example: a task that sends 2,000 tokens (about 1,500 words) and receives a 500-token answer costs $0.0024. At 1,000 tasks a day, budget $72 a month. The price calculator redoes this with your own volumes.
Performance and benchmarks
Epoch AI does not yet publish a capabilities index for Aion-RP 1.0 (8B). We therefore show no made-up performance rating: only price, context and features count towards its score.
Features, privacy and local use
- It does not support tool calling: it is not suited to driving an AI agent that has to act.
- Its knowledge stops at December 2023.
Its weights are not published: it can only be used through the AionLabs API or a broker such as OpenRouter, which means sending your data off your machines.

Verdict
Computed score: 22/100, from public data (performance, price, context, features).
Limitations
- No tool calling: unusable as an agent's brain.
- No independent score published: performance cannot be verified.
- Older generation, often replaced by a newer model from the same vendor.
- Text only: reads neither images nor files.
Avoid if…
- your data must not leave your servers;
- you are building an agent that must call tools;
- you analyse long documents in one go.
