Deepseek V4 Flash 0731 chat template leaks

Recently (today only) I’ve noticed the model starts repeating itself in loops after a small amount of context. This has happened several time in independent chats. It will look like this:

<｜begin▁of▁sentence｜><｜begin▁of▁sentence｜><｜begin▁of▁sentence｜><｜begin▁of▁sentence｜><｜begin▁of▁sentence｜><｜begin▁of▁sentence｜><｜begin▁of▁sentence｜><｜begin▁of▁sentence｜><｜begin▁of

▁sentence｜><｜begin▁of▁sentence｜><｜begin▁of▁sentence｜><｜begin▁of▁sentence｜><｜begin▁of▁sentence｜><｜begin▁of▁sentence｜><｜begin▁of▁sentence｜><｜begin▁of▁sentence｜><｜begin▁of▁sentence｜><｜begin▁of▁sent

ence｜><｜begin▁of▁sentence｜><｜begin▁of▁sentence｜><｜begin▁of▁sentence｜><｜begin▁of▁sentence｜><｜begin▁of▁sentence｜><｜begin▁of▁sentence｜><｜begin▁of▁sentence｜><｜begin▁of▁sentence｜><｜begin▁of▁sentence

｜><｜begin▁of▁sentence｜><｜begin▁of▁sentence｜>

I suspect some model param or quant was changed very recently and it broke something.
