+            The model will output the same cache format that is fed as input. If no `past_key_values` are passed, the

+            is useful if you want more control over how to convert `input_ids` indices into associated vectors than the

+            If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding (see
