How can I extract the number of repetitions used and the total number of tokens into a variable?

[dlubom]

Since I am processing data in large batch quantities, I would like to keep track of the number of retries. How I could do it?

Using create_with_completion (Anthropic), I extract the number of in/out tokens, but as I understand, this is the number for the last successful attempt. How can I extract the total number of tokens used?
