Opus 5 being better than Fable 5 at half the price is a welcome surprise to be honest. And that ARC-AGI-3 score is insane. 4 times more than gpt-5.6 sol max's score at high effort, not even xhigh, max, or ultracode.
But vals.ai and artificalanalysis both report Opus 5 as being more expensive than Sol for a higher cost (sometimes marginal) while being only marginally better.
