   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

      Wtf is GPT-6 Sol, I though GPT-6 is Astra?

         Number is generation Name is the size (Luna smallest to Astra largest)

            Then what is Astra high-extra high-Ultra? That’s effort?

               Yes that is number of reasoning tokens used.

               Performance increases both with larger model (Luna vs Sol)

               And with more reasoning (low vs xhigh)
