What are the best free multi-model AI clients?

Flocci AI Tools lists 9 multi-model AI clients, ordered free tiers first: Chatbox, NextChat, Cherry Studio, LibreChat and ChatHub. 7 of the 9 are free or have a free tier. Every entry states what it uniquely does, not a score.

Are there completely free multi-model AI clients?

Yes — 4 of these are marked fully free with no paid plan attached: Chatbox, NextChat, Cherry Studio and LibreChat. The rest are freemium, trial or paid, and each row states which.

What should I look for in multi-model AI clients?

Start with what you need to do: reach every frontier model from one chat window. Then check the pricing tier, because "free" here means no paid plan at all while "freemium" means a free tier under paid plans. Every tool on this page lists both.
