API README

Imagen 3

google/imagen-3 creates original still imagery from detailed written art direction, resolving subject, environment, composition, lighting, material, and style without a source image. Imagen 3 is known for strong prompt adherence, photorealism, and clear embedded text across a wide variety of visual styles. This combination makes the model a practical choice when the creative outcome depends on those qualities rather than on a generic media conversion.

For production work, ten aspect ratios support wide, square, and portrait placements, while an optional seed makes it easier to revisit a promising visual direction. The result is most reliable when the source material and creative brief clearly describe the intended subject, progression, visual or sonic character, and the qualities that must remain unchanged.

Highlights

Prompt fidelity translates detailed descriptions into composed, relevant imagery.

Photorealistic rendering produces convincing lighting, materials, depth, and natural detail.

Typography generation renders clearer words and graphic text within the scene.

Style versatility moves between photography, illustration, design, and conceptual artwork.

When to Use

✅ Good fit	❌ Consider alternatives
The model's named workflow matches the source material and intended output	A different input modality or model route is required
A managed asynchronous result is suitable for the production pipeline	A synchronous, interactive editor is essential
The documented controls cover the required duration, framing, or format	The project needs controls outside this endpoint's schema
Creative iteration benefits from a repeatable request structure	Exact deterministic pixels, frames, geometry, or samples are mandatory
A finished downloadable media asset is the desired deliverable	Editable source layers or a native project file are required

Prompt Guide

For generation, state the intended result first, then add the subject or source treatment, progression, style, and delivery constraints. Keep one creative variable per phrase, use the documented field names for controls, and change one setting at a time when comparing results.

  "aspect_ratio": "21:9",
