  ### Who can help?
  
  @ArthurZucker
  
  ### Information
  
  - [ ] The official example scripts
  - [ ] My own modified scripts
  
  ### Tasks
  
  - [ ] An officially supported task in the `examples` folder (such as GLUE/SQuAD, ...)
  - [x] My own task or dataset (give details below)
  
  ### Reproduction
  
  Use Phi3 with any cache configuration, including default (DynamicCache)
  
  I think get_max_length is probably declared on a mixin that isn't on the cache classes yet?
  
  ```
  comfy_extras\nodes\nodes_language.py:361: in execute
      return model.generate(tokens, max_new_tokens, repetition_penalty, seed, sampler),
  comfy\language\transformers_model_management.py:228: in generate
      output_ids = transformers_model.generate(
  ..\..\.venv\Lib\site-packages\torch\utils\_contextlib.py:116: in decorate_context
      return func(*args, **kwargs)
  ..\..\.venv\Lib\site-packages\transformers\generation\utils.py:2224: in generate
      result = self._sample(
  ..\..\.venv\Lib\site-packages\transformers\generation\utils.py:3198: in _sample
      model_inputs = self.prepare_inputs_for_generation(input_ids, **model_kwargs)
  C:\Users\bberman\.cache\huggingface\modules\transformers_modules\c1358f8a35e6d2af81890deffbbfa575b978c62f\modeling_phi3.py:1292: in prepare_inputs_for_generation
      max_cache_length = past_key_values.get_max_length()
  ```
  
  ### Expected behavior
  
  related to #35168?
  
  I'm not sure why this is only coming up with phi-3 so far
