Question about response_format parameter in chatting mode.

[YiandLi]

Hello, I have a question about response_format parameter , when I use create_chat_completion method, there is a response_format parameter, but it may not work if there is no "schema" key.

In the method "chat_completion_handler":

        if response_format is not None and response_format["type"] == "json_object":
            try:
                # create grammar from json schema
                if "schema" in response_format:
                    grammar = llama_grammar.LlamaGrammar.from_json_schema(
                        json.dumps(response_format["schema"])
                    )
            except Exception as e:
                grammar = llama_grammar.LlamaGrammar.from_string(llama_grammar.JSON_GBNF)

In my opinion, if there is no "schema" in response_format ， it will just skip this parameter. Is that right ?

Also, I have another question, is every model support this parameter ? Or where I can find which model could support this parameter ?
