Look at the ARC site. The scores of these models is plotted against their "cost per task". All of these huge jumps come along with massive increases in cost per task. Including Gemini 3.1 Pro which increased by 4.2x

ARC 2 was made specifically to artificially lower contemporary LLM scores, therefore any kind of model improvements will have outsized effects

Also people use "saturated" too liberally. The top left corner 1 cent per task is saturated IMO. Since there are billions of people who would perfer to solve arc 1 tasks at 52 cents per task. Arc 2 a human would make thousands of dollars a day with 99.99% accuracy
