# Notes

\- I think I fixed the extra token stuff some users seem to be facing, while retaining everything else? It's some error alright.
<br>\- If you're using XML tags, you may see weird malformed stopping strings. Just add them to your current list. and move on.
<br>\- Its pretty nice, imo. I've been messing around with it a lot.
<br>\- Make sure the ChatML template is correct, I think there's some issues with the one used in SillyTavern which might cause improper replies?

Reup due to issues I faced on my page, crashing every time i go in here. works fine now? so yay?

Changes: Weights are the same, literally. go and check the checksum.
Credit to ArliAI for the model tokenizer configs and json I yoinked, to fix the tokenizer mess (in v3) I made, hence why config.json had their model name.
Same stuff applies
