POSThttps://stability-ai.mpp.paywithlocus.com/stability-ai/upscale-creative?utm_source=zero.xyzChoose this endpoint when you want AI to creatively interpret and add detail during upscaling — not just interpolate pixels. It's ideal when the source image is low quality and you want a visually richer, AI-hallucinated high-res result guided by a text description. Prefer the Conservative upscale endpoint if you want pixel-faithful enlargement without creative deviation.
