AI Text Generator - Which uncensored LLM?

I would like to know which uncensored open source LLM is running behind these two perchance AI Text Generators:

https://perchance.org/g33kbar-ai-text

https://perchance.org/ai-text-generator

And do they use both the same model?

For my use cases it works very good and i would like to run the LLM on my private local GPUs.
