Best Free Multi-model AI clients — straight answers

What are the best free multi-model AI clients?

Flocci AI Tools lists 6 of them, ordered free tiers first: Cherry Studio, LibreChat, Abacus ChatLLM, ChatHub and t3.chat. 5 of the 6 are free or have a free tier. Each entry states what it uniquely does rather than a score.

Which of these are completely free?

2 on this page are marked fully free with no paid plan at all: Cherry Studio and LibreChat. The remaining 4 are freemium, trial or paid, and each is labelled with its exact tier so nothing surprises you at sign-up.

How is this list ordered?

Free tools first, then freemium, then trial, then paid, and alphabetically inside each tier. Nobody pays to appear higher: Flocci AI Tools carries no ads, no sponsored slots and no paid listings, so the order reflects price and nothing else.
