Yi-34B Model(s) Repetition Issues (alien.top)

Messing around with Yi-34B based models (Nous-Capyabara, Dolphin 2.2) lately, I’ve been experiencing repetition in model output, where sections of previous outputs are included in later generations.

This appears to persist with both GGUF and EXL2 quants, and happens regardless of Sampling Parameters or Mirostat Tau settings.

I was wondering if anyone else has experienced similar issues with the latest finetunes, and if they were able to resolve the issue. The models appear to be very promising from Wolfram’s evaluation, so I’m wondering what error I could be making.

Currently using Text Generation Web UI with SillyTavern as a front-end, Mirostat at Tau values between 2~5, or Midnight Enigma with Rep. Penalty at 1.0.

I encounter this a lot with the Yi 34B models to the point where I've basically stopped using them for chat. I've tried a huge variety of settings, presets, quants, etc. I've used koboldcpp and text-generation-webui, I've used EXL2, GGML, and GPTQ. The issue appears consistently after the context grows past a certain size. Partial or entire messages will repeat. It will also get stuck where regenerating will always result in the same response unless drastic changes to settings are made and usually it just changes the message that it's stuck on. Smaller changes to the settings will just result it in changing the wording slightly of the stuck message.
