Hidream O1 by hidream-ai - generate stunning images from text prompts with state-of-the-art AI. Supports multiple aspect ratios, styles, and high-resolution output for creative and commercial use.

Input

Prompt(string)

Text prompt for image generation, editing, or subject-driven personalization.

Aspect Ratio(string)

The aspect ratio of the generated image. Allowed values: 21:9, 16:9, 3:2, 4:3, 5:4, 1:1, 4:5, 3:4, 2:3, 9:16.

Images(array)

Optional reference images. Use none for text-to-image, one for image editing, or multiple for subject-driven personalization.

Seed(integer)

Random seed for reproducible generation.

Output Format(string)

The format of the generated image. Allowed values: jpeg, png.

Input Schema

5 parameters · 1 required · 4 optional

Parameter	Type	Required	Description
`prompt`	string	Required	Text prompt for image generation, editing, or subject-driven personalization. · Min length: 1
`seed`	integer	Optional	Random seed for reproducible generation.
`images`	string[]	Optional	Optional reference images. Use none for text-to-image, one for image editing, or multiple for subject-driven personalization.
`aspect_ratio`	string	Optional	The aspect ratio of the generated image. · Options: 21:9, 16:9, 3:2, 4:3, 5:4, 1:1, 4:5, 3:4, 2:3, 9:16 · Default: "16:9" 21:916:93:24:35:41:14:53:42:39:16
`output_format`	string	Optional	The format of the generated image. · Options: jpeg, png · Default: "png" jpegpng

Output Schema

Field	Type	Description
`id`	string	Unique identifier for the generation task
`status`	string	Task status: pending, running, completed, failed, timeout
`model`	string	Model used for the generation
`outputs`	array	Array of output items
`outputs[].url`	string	URL of the generated artifact
`outputs[].content_type`	string	MIME type (e.g. image/png, video/mp4)
`error`	object \| null	Error details if failed, null on success

Async Workflow

This model uses asynchronous execution. Submit a request and poll for the result.

Submit — POST to /v1/run, receive an id
Poll — GET /v1/run/{id} until status is completed, failed, or timeout
Retrieve — Read outputs from the completed response

API README

HiDream O1

hidream-ai/hidream-o1 uses reasoning-oriented visual generation to plan and synthesize images from complex written intent. HiDream-O1 focuses on understanding multi-step creative instructions and relationships before rendering, helping intricate compositions remain logically and visually coherent. 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-o1, it fits visual problem solving, structured layouts, complex concept scenes, and briefs with several interacting requirements that are difficult for straightforward prompt matching. 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

Reasoning-led composition plans complex visual relationships before synthesis.

Multi-step instruction following handles briefs containing several linked requirements.

Spatial coherence maintains logical placement, interaction, and scene structure.

Detailed rendering converts the planned visual solution into polished imagery.

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.
