As of version 0.6.0, the llama_index library no longer automatically logs runtime information and details about its processes. However, you can enable logging by adding the following to the beginning of your script:

import logging
import sys

logging.basicConfig(stream=sys.stdout, level=logging.INFO)

This will show the token counts for embedding and LLM usage.

The level can be changed to logging.DEBUG for even more details, such as the actual data it’s processing.
