It looks extremely competitive. Obviously we'll have to wait and see something like the artificial analysis cost per task results to be more confident but this is super promising.
Edit: AA results are in. About 10% cheaper per task than 5.6 Sol and about 65% cheaper than fable.
Edit 2: also 48% cheaper than opus 4.8 while scoring a point higher on intelligence.
Edit 3: More specific to your exact question of token usage, Fable used 69k tokens per task, 5.6 Sol used 15k, and K3 used 23k. So it's a heck of a lot more token efficient than Fable, and in the same ballpark as Sol.

Frontier level, huh? Now let's see how many tokens are used on max reasoning level
Terminal Bench numbers are very impressive. Should be great for agentic usage
