description: >-
  Plan and price data for the PLaMo API, read from Preferred Networks' own PLaMo product site
  (plamo.preferredai.jp/api). The pricing page is a client-rendered single-page application; the
  plan table below was read verbatim from the application's own data structures served at
  https://plamo.preferredai.jp/assets/index-lyzY8EKj.js, and the existence of the Standard plan is
  independently confirmed in PFN's own press release for PLaMo 3.0 Prime
  (https://www.preferred.jp/ja/news/pr20260622), which prices its benchmark cost comparison using
  "PLaMo API の standard プラン" rates. Values are recorded in the currency and units the provider
  publishes (Japanese yen per 1M tokens); they are not converted.
