THE SHORT VERSION
The fine print: the '9% of the cost' claim is wrong — it's 78% for the 27B
The viral '9% of the cost' line belongs to a different model. The 9 percent figure is for Qwen3.8-Flash-Next; the 27B with the manager harness costs about 78 percent of Fable 5 at list prices — $47.82 a pass against $61.11.
And the tie itself is statistical noise: the paper's p-value for the 27B-with-manager versus Fable 5 single is 0.88 after correction. You can say it matches Fable 5. You can't say it beats it.
