API README

HiDream I1 Dev

hidream-ai/hidream-i1/dev creates high-quality still imagery from detailed written art direction, resolving subject, composition, lighting, materials, and style. HiDream-I1 Dev exposes the development-quality balance for experimentation, giving creators detailed prompt following with more economical iteration than the Full tier. 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/dev, the Dev tier fits prototyping, workflow development, and iterative art direction where useful detail and style range are needed before final rendering. 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.

Development-tier balance supports capable experimentation at practical iteration cost.

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.
