Our take
Written Sep 2, 2026Aion-3.0 is a proprietary text-only model from AionLabs with a 131,072-token request limit, released in July 2026. It offers identical pricing across its two hosting channels and a measured 41 tokens per second on the direct endpoint, though no quality scores are available yet.
Pick this for budget-conscious text tasks where a 128K-token request limit is enough and you want predictable costs across providers. Use the direct endpoint if throughput predictability matters, since only that channel is measured. Skip it if you need benchmark-verified quality, multimodal input, or self-hosting options.
The case for it
- Identical pricing across both tracked providers — no channel arbitrage needed.
- Proprietary hosting with a measured 41 tokens per second on the direct endpoint.
The case against it
- No measured benchmark scores in our data: no chat, coding, or reasoning scores listed.
- Throughput unmeasured on OpenRouter; only the direct endpoint shows 41 tokens per second.
- Parameter count undisclosed, so hardware planning and size comparisons are impossible.
How good is it?
We hold no score for this model.
So there is no figure here for everyday use, coding, agent work or writing. That is a gap in our data, not a low score.
