Core capabilities

Generate (imagen4-generate): Required prompt (max 5000 chars). Optional negative prompt (max 5000 chars), aspect ratio 1:1 / 16:9 / 9:16 / 3:4 / 4:3 (default 1:1), seed string (≤500 chars). One image per request.

Fast (imagen4-fast): Same prompt and negative-prompt limits. Output 1–4 images per request; integer seed; five aspect ratios (default 16:9).

Ultra (imagen4-ultra): Same prompt and ratio options as Generate with flagship quality priority; one image per request; seed string (≤500 chars); default aspect 1:1.

All tiers are text-to-image only—no image upload. Credits shown on Generate before submission.

Workflow

Everyday stills: write a detailed prompt → pick Generate → set aspect ratio and optional negative prompt → generate → download.

Batch ideation: use Fast with num images 2–4 → compare variants from one prompt → lock direction with integer seed.

Final delivery: switch to Ultra for hero assets → optional seed string for reproducible composition → pair stills with Veo 3.1 video (first/last frames) when you need motion.

All workflows run in the browser—no local GPU required.
