hey @valkyrie i had a bit of a closer look at the _parse_and_tokenize function of the zero-shot pipeline and indeed it seems that you cannot specify the max_length parameter for the tokenizer.
so if you really want to change this, one idea could be to subclass ZeroShotClassificationPipeline and then override _parse_and_tokenize to include the parameters you’d like to pass to the tokenizer’s __call__ method.
hope that helps!
