Get metris (input_token, output_token) from arun function

[hoanganh2070]

I'm using await self.client.arun(message=message, stream=True) to stream chat responses in my chat_stream method. It works fine and I can iterate over the responses, but I would like to extract metrics (e.g., token etc.) from the stream.

How can I access the metrics from the response_stream or each response during or after streaming?

I tried printing dir(response_stream) and dir(response) but couldn't find a clear metrics or usage attribute.

Is there a built-in way to access this metadata, or do I need to enable/configure something in the client
