@vidyasiv some models like qwen2 already have chat-template inside tokenizer, should we utilize that?

@libinta , could you clarify? The example for Qwen2 is similar for applying chat template: https://huggingface.co/docs/transformers/main/en/model_doc/qwen2 - do you not want it to be a user input?
Guidance from documentation is to always set it explicitly:
https://huggingface.co/docs/transformers/main/en/chat_templating#what-are-default-templates

relevant lines: You can find out what the default template for your tokenizer is by checking the tokenizer.default_chat_template attribute. This is something we do purely for backward compatibility reasons, to avoid breaking any existing workflows. Even when the class template is appropriate for your model, we strongly recommend overriding the default template by setting the chat_template attribute explicitly to make it clear to users that your model has been correctly configured for chat.

either way is fine

I think there was an error in my understanding of how this works.. The tokenizer "chat_template" or tokenizer.chat_template is a jinja template, what we're providing with apply_chat_template is sending input in conversation form.
https://huggingface.co/docs/transformers/main/en/internal/tokenization_utils#transformers.PreTrainedTokenizerBase.apply_chat_template
. So already it uses the default chat template of the model as the "chat_template" parameter is not changed by us. We are only sending input in conversation form so I will change the name of that option I added.

@libinta, For cohereai on v1.16.0 I see performance:

HPUs Max New tokens Batch size Throughput (tokens/s) Memory Allocated
1 100 2 60.517 83.08
1 100 4 PT dev mem error
1 200 2 PT dev mem error

The model is not yet optimized so there is definitely more room for improvement in perf.
Removed model from top level README as it is not optimized as yet.

shouldn't the conditional be part of the upper one?
