API README

HiDream I1 Full

hidream-ai/hidream-i1/full creates high-quality still imagery from detailed written art direction, resolving subject, composition, lighting, materials, and style. HiDream-I1 Full prioritizes the family's highest text-to-image fidelity, detail, composition, and aesthetic finish. 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 with hidream-ai/hidream-i1/full, the Full tier suits final campaign images, complex concept art, and demanding visual briefs where subtle textures, accurate relationships, and presentation quality justify a slower render. 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

Detailed text-to-image synthesis resolves complex scenes, materials, lighting, and visual relationships.

Strong prompt adherence follows subjects, attributes, spatial composition, and stylistic direction.

Style versatility spans photorealism, illustration, graphic design, and conceptual artwork.

Full-quality rendering maximizes texture, composition, and final visual polish.

When to Use

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