FWIW I’m pretty sure OpenHands has some users who use a few local models; it’s not ideal at the moment, but it will improve.
There are some other options. I thought I remember that Minimax was for free… but maybe it was for a limited time. Right now, my agent found these prices for what is worth, sorry.
I think OpenRouter has quite a number of models for free though, they’re named with “:free” at the end of the model name. It also has promotions when a new LLM is released in stealth mode for the community to try it, and then it’s typically also for free - very good models, too.
