# Is Yumina free?

Yes. You can play, build and publish without paying anything. Every account comes with a free AI model and a daily allowance that refills each day.

Yumina is open source, and we don't make money from how much you chat. Once a company earns on every message, it slowly starts serving worse models, cutting memory short and selling your data. That is why you can bring your own key from a provider like OpenAI or OpenRouter and pay them directly. If you don't have one, we offer the same models on our site, and we don't profit from that either. A paid plan covers the cost of running stronger models for you, with more playing time.
