A question about assistant token usage

Hello, folks. I am currently experimenting with assistants and have not been able to fully understand how it calculates the number of tokens. Each time I execute a message, the token count increases, and what I am unsure about is:

  1. Is it the cumulative number of tokens I have used in this thread?
  2. Or is it the number of tokens that was used in the previous execution?
