Free AI models: every chat model on the Free plan

What is free in Quad Chat

31 of the 51 chat variants in Quad Chat run on the Free plan, from 17 labs: OpenAI, Google, Anthropic, Moonshot AI, Meta, Thinking Machines, Z.ai, xAI and 9 more. The Free plan costs $0, needs no credit card and does not expire. The other 20 variants need a paid plan. Free does not mean unlimited. Every plan, Free included, draws on one monthly pool of shared credits across all models and web search. The Free plan includes 100 credits a month. Cheaper models use fewer credits per message than frontier models, so the free models below stretch the furthest.
