   > Cached input costs just $0.10 per million tokens—95% less than standard input pricing and 50% less than GPT‑6 Sol’s cached input pricing

   This is the actual big announcement. 50% cheaper cache than GPT-6 Sol will get you far more mileage on Codex.

      Exactly half as expensive as Opus 5.5 in every API pricing metric

         And half as good. I didn't have great experiences with Anthropic models in the past, but Opus 5.5 seems to have turned a major corner. It is churning through tasks significantly more quickly and efficiently.

         Suggest trying it out yourself: Ask for something difficult from GPT-6 Sol and Opus 5.5 and watch what each one does. The difference is stark.

         Edit: Defining "difficult" as a complex coding or systems task (or even series of them in a single prompt).

            For my personal experience, antropic model have better use experience except for 4.7 and 4.8 though. 4.7 and 4.8 feels like expensive downgrade of 4.6 to me (I didn't know why these two should even exist)

               For me Anthropic models from 4.7 to 5 including where bad and ate tokens like crazy. Task delivery was worse than GPT 5.6 and token usage was 2-3x higher.

               Looks like 5.5 is the new 4.6
