Hey! For example, I send instructions (10k tokens) to API and begin a thread. I added messages to the thread from time to time. Will I pay for 10k tokens in instructions whenever I send a message in the thread, or will I pay for instructions only once and later only for messages in the thread?

You pay for all tokens in and out of the API.

Instructions. Does it cost for each run?

A lot of details around this don’t seem to be documented anywhere. We’re talking about it here.
