This has happened before with quantizations and other backends (ones not used by the research lab). Give it a week, download latest versions of everything, and try again.

I'm having the same issues, the more I use it. The repetition penalty doesn't seem to help.

I get some really amusing 'reflective' responses, but I think it needs a bit more cooking. Maybe I'll try another variant.

perhaps increasing repitition_penalty might be helpful
