Alpha's edge

Subject identity stays stable through successive inpaints — the exact failure mode that cost Beta points in the editing battery. If you iterate on a hero image for hours, this is the difference that matters.

Beta's edge

$0.004 per image against Alpha's $0.04 (published pricing, verified 2026-10). At 10,000 images a month, that is $40 vs $400. For catalogs and A/B creative volume, the math is closed.

Where this sits

Alpha holds #1 and Beta #2 on the main 2026 index. The 0.4-point gap is real. Whether it matters depends entirely on which side of the quality/cost line your work lives.
