Image Generation - Picking the Right Model
Meet the Models
Schnell — Cheap & Fast (Stylised)
Idea machine. Fire off dozens of looks, storyboards, and thumbnails in minutes.
Use for: rapid concepting, moodboards, A/B variants.
Why it shines: lowest cost, lowest latency.
Trade-offs: softer micro-detail; tiny text/hands can wobble.

Dev — Balanced (Sharp & Reliable)
Your daily driver. Sharp, stable, and consistent without Pro’s price tag.
Use for: social/blog visuals, ecommerce images, YouTube thumbnails.
Why it shines: strong edges, solid lighting, dependable output.
Trade-offs: not print-perfect; a light upscale/cleanup helps.

Pro — High Quality (Pixel-Perfect)
Hero maker. Every pixel earns its place.
Use for: ads, close-ups, faces/hands, logos in image, print work.
Why it shines: highest fidelity, steadier composition, better typography.
Trade-offs: slower, pricier, and overkill for small/mobile assets.
