  • Paid members are charged the member price, 40% below the list price.
  • Cache hit: a prefix repeated from earlier requests (such as a system prompt or a long document you keep referring to) is cached, and the cached part is billed at the cache price, about 5% of the input price.
  • Cache write: content written to the cache the first time is billed at the cache write price; later hits are billed at the cache hit price.
  • Input and output are billed separately by actual tokens; reasoning tokens count as output.
