I think there is something wrong with repetition\_penalty. It is not being applied.

I have some models, e.g. [generation\_config.json · adenhaus/mt5-small-tata at main](https://huggingface.co/adenhaus/mt5-small-tata/blob/main/generation_config.json) which have repetition\_penalty set. Just a few weeks ago, when I changed the repetition\_penalty, I could see the output change. Now, when I change it, the output is always the same, the penalty is not being applied.

Maybe this was broken in some recent update?

This seems to be working again now, but I am certain I had the issue yesterday.
