How does billing work?

Chat models bill per input and output token at the listed per-million-token rates, metered per request against your deeprelay balance. Where a cached-input rate is listed, the part of a prompt the serving partner answers from its prompt cache (reported as prompt_tokens_details.cached_tokens) bills at that lower rate instead of the input rate.
