report.ai-usage-open-result@1: the open AI meter (plan L40/L41). What the whole network spends on AI, in public: the tokens, the share of them that came from a provider cache, the share that the own keys of people paid, and the spend by week. No person, no site and no key is in it: the rows are summed before they are answered.
