Describe the issue

Hello Soulkyn Support,

I’m experiencing a chat generation bug. AI replies are being corrupted with random letters/tokens such as “L”, “I”, “S”, and “T” inserted between words. Sometimes the reply degenerates into long repeated rows of “I” characters.

It happens in chat with:

  • Kyn/Character: Slave Market / Elias
  • UI language: Korean
  • Device/browser: Android Chrome
  • Approximate time: 2026.07.04 AM 2~4
  • URL path shown: /l/ko-KR/v1C

I attached screenshots showing the issue. Please check whether this is related to the recent fast model / wrong parameter issue reported in the Bugs: Chat forum.

Thank you.

I’m attaching one more photo that shows an issue in the conversation. :sob:

The same phenomenon is still recurring.

Advanced or normal model, all kyns or just this one, all threads or just this chat thread?

I’m a Premium user.

I’m not sure whether it was the advanced model or the regular model, because I didn’t manually change the model.

So far, this issue happened only with this one Kyn, and only in this specific chat thread. I haven’t seen the same issue in other Kyns or other chat threads.

After I deleted the broken chat thread and started a new chat with the same Kyn, it started working normally

If this ever happen again, if you don’t mind sharing the message or messages before the bug happens next time. Thanks. If you don’t want to share that’s also fine it would be helpful if it’s a fine tuning issue.
