You need to install a difference database there are many other LLMs and some are free. Sourceforge and GITHub are the more well known websites for various kinds of software including databases.. OpenAI will not allow any adult content.
While other models may be free, they are not as nearly as powerful as OpenAI's. Their text completion model allows for adult content for now (you risk getting banned though).
I think it's good to have options. Maybe in the future I can add more engines to the app, like you suggest.
