phi3 chat format

[SimJeg]

Hello,

Could you add the chat format for the phi3 models ?

It is described here :

<|user|>\nQuestion<|end|>\n<|assistant|>\nAnswer<|end|>\n

Maybe something like this in llama_chat_format.py ?

@register_chat_format("phi3")
def format_phi3(
    messages: List[llama_types.ChatCompletionRequestMessage],
    **kwargs: Any,
) -> ChatFormatterResponse:
    _roles = dict(
        user="<|user|>\n",
        assistant="<|assistant|>\n",
    )
    _sep = "<|end|>\n"
    _messages = _map_roles(messages, _roles)
    _messages.append((_roles["assistant"], None))
    _prompt = _format_no_colon_single("", _messages, _sep)
    return ChatFormatterResponse(prompt=_prompt, stop=_sep)
