   I don't see how anyone can be using Claude with prices like this, it's pretty incredible what the OpenAI team is doing, w.r.t model quality and pricing.

     Prices per 1M tokens     Claude Opus 5.5    Claude Opus 5
      Cache reads              $0.20              $0.50
      Input tokens             $4                 $5
      Output tokens            $20                $25
      Cache writes             $5                 $6.25

      The major difference being the 1M token context window. Once you exceed 272K input tokens, Codex Sol is roughly the same price as Opus; and Astra similar to Fable.
