Hey @datavistics -- the problem is not present on `main`, but rather in the previous release (which we can't fix unless we make a new release) 

See these docs: https://huggingface.co/docs/transformers/main/en/main_classes/text_generation<|||||>I still get the broken link here: https://huggingface.co/docs/transformers/en/main_classes/text_generation#transformers.GenerationMixin.contrastive_search

Which links to v4.26.1 in one of the links.<|||||>Should be fixed by #22078 on main.
