They're claiming a drop in token use too, and that it nets to 40% cheaper.
I tested it with Claude Code, and I can confirm it's way cheaper, better, faster and less verbose than Opus 5.
parent means that they could get more client / a larger part of the market, which would lead to more income (more tokens) despite lower marginal prices
Unfortunately, they're full of it https://artificialanalysis.ai/models/claude-opus-5-5#token-u...
It does work out to be a similar cost per task though
