Everything about Aion-3.0-Mini

What you need to know

Aion-3.0-Mini is a language model from AionLabs, released on May 14, 2026. That makes it 5 months old as of October 22, 2026. Its weights are not published, so it only runs remotely, through the AionLabs API or partner hosts (4 listed on models.dev). It has a reasoning mode: it can "think" before answering, which helps with multi-step problems but uses more tokens, and therefore more money.

We file it under budget models (24 models in this category on the site).

Measured performance

As of October 22, 2026, Epoch AI publishes no score for Aion-3.0-Mini on our basket's benchmarks. To place it, rely on its specifications and price, then test it on your own cases.

Pricing and budget

Aion-3.0-Mini costs $0.70 per million input tokens and $1.4 per million output tokens (median of 4 providers, checked on October 22, 2026).

In practice, an agent task that reads 20,000 tokens and writes 2,000 costs about $0.017, or $16.8 for 1,000 such tasks.

That is 1.2 times the median output price of budget models ($1.13).

To estimate your own budget, use the agent cost calculator.

What it can do

Its context window reaches 131,072 tokens, roughly 197 pages of text at 500 words per page: enough for a medium-length document. A single answer can run to 32,768 tokens.

It accepts as input: text.

It can call tools (functions, APIs), which makes it a possible foundation for an AI agent.

When to choose it

Given its category, Aion-3.0-Mini is mainly aimed at high volumes where every cent counts: sorting, information extraction, summaries, simple assistants.

Before adopting it, test it on your own examples: benchmarks measure standard tasks, not your job.
