Where it sits on price
Of the 30 models in this catalog, Claude Opus 5.5 ranks 26 by output price — cheaper than 2 and more expensive than 25. Cached input is billed at $0.200 per million tokens, about 5% of the standard input rate, so a high cache-hit rate changes the picture.
Price is not capability. A model that is half the price but needs two attempts, or that cannot hold your context, is the more expensive choice. Use these figures for budgeting and run your own evaluation for the quality decision.
