Describe the bug

@afourney, I and Soham were debugging the default model with some logs interestingly the conversible agent logs gave the below JSON(PFA). Containing the 2 models in the llm_config. Mostly when the agent config contains the function calls.

Steps to reproduce

No response

Expected Behavior

Expect to be only one model defined in the config.

Screenshots and logs

Additional Information

I think this is happening coz of this piece of code in ConversableAgent line number 114. I might be wrong as well

if llm_config is False:
    print("LLM_CONFIG FALSE CASE")
    self.llm_config = False
    self.client = None
else:
    self.llm_config = self.DEFAULT_CONFIG.copy()
    if isinstance(llm_config, dict):
        self.llm_config.update(llm_config)
        print("LLM_CONFIG NOT FALSE CASE")
    self.client = OpenAIWrapper(**self.llm_config)
