@kalyanjk limit_hpu_graphs should already be in the generation config of the model and thus in the model_kwargs. I think it's rather an issue of adapt_transformers_to_gaudi not being called in https://github.com/huggingface/optimum-habana/blob/main/tests/transformers/tests/generation/test_utils.py.
