Aion Labs lists three models in this rating: Aion-3.0 at $3 input and $6 output per 1M tokens, the Mini variant at $0.70 and $1.40, and the earlier 2.0 generation in between.
The line is small and priced in the mid tier. As with the other smaller labs here, the sensible approach is a direct benchmark against a comparable Qwen, GLM or Mistral model on your own task before committing.

How to choose
- Benchmark against a comparable model from a larger vendor before committing production traffic — line-ups this size get less independent testing.
- Start with Aion-3.0-Mini at $0.7 / $1.4 per 1M tokens; it is the cheapest entry point here.
- Move up to Aion-3.0 at $3 / $6 only where the cheaper variant visibly fails, not by default.
- Check the context window against your longest input — the largest here is Aion 3.5 at 256K tokens.
