Frequently asked questions
How does the model picker choose?
It maps your task and priority to the model that suits it best, based on each model published strengths, its limits and its price. It is an editorial recommendation, not a benchmark score.
Can I switch models mid-conversation?
In AimiChat you can. Start with a fast, cheap model and move up when an answer needs more depth. The conversation carries over, so nothing is lost.
Which model is best overall?
There is no single best model. The strongest models cost the most and are slower, so for everyday questions a cheaper model is often the better choice.
