classDynamicCache(Cache):"""A cache that grows dynamically as more tokens are generated. This is the default for generative models.It stores the Key and Value states as a list oftensors, one for each layer. The expected shape for each tensor is`[batch_size, num_heads, seq_len, head_d...

"unk_token": "<unk>", "use_default_system_prompt": true } In this example from Zephyr, we see an arg max_model_length. In this case it seems to be a useless placeholder. Often it is informative, but not always. So lets instead try our corresponding config.json: ## config.json ...
