Most marketing, product, and content workflows start here. Step up to Ultra when alignment must be tighter; drop to Fast for high-volume drafts.

Same up-to-2K support as Ultra — enough for marketing assets and zooming into complex compositions.
Fast for volume, standard Imagen 4 as daily workhorse, Ultra when alignment and detail decide delivery.
Multi-panel comics with readable console text, vintage postcards, summit photography, alien landscape fashion — all from Google's Imagen 4 launch and GA announcements.

Balanced instruction following, in-image text, up-to-2K photoreal detail, cross-style coverage, and SynthID by default.
Three panels, four verbatim in-image text blocks, specified wardrobe, specified light direction — Ultra is the tier built to satisfy all of them in one render.

Every Imagen 4 family image carries Google's invisible SynthID watermark — provenance travels with the file without affecting visible design.
