Features
HiDream-O1-Image (Text-to-Image)
HiDream-O1-Image is a unified, next-generation image-generation model. A single native model handles text-to-image, image editing, and subject-driven personalization — no external adapters, controllers, or pipelines required. The text-to-image endpoint produces sharp, detailed visuals at resolutions up to roughly 2K (2048×2048) straight from a text prompt.
Why Choose This?
- Unified native model — One model, multiple modes (text-to-image / edit / personalization). No swapping or chaining required.
- High-resolution output — Generate detailed images up to ~2048×2048 with strong composition and natural lighting.
- Strong prompt adherence — Faithfully follows complex, multi-clause descriptions including style, mood, and on-image text.
- Flexible aspect ratios — Supply any custom width/height up to the supported maximum (the model snaps to the closest supported resolution).
- Multiple output formats — JPEG, PNG, or WEBP to match downstream pipelines.
- Reproducibility — Use a fixed
seedto recreate exact results.
Parameters
| Parameter | Required | Description |
|---|---|---|
| prompt | Yes | Text description of the image you want to generate. |
| size | No | Output image size as WIDTH*HEIGHT (default: 2048*2048). The model snaps to the closest supported resolution. |
| output_format | No | Output format: jpeg, png, or webp (default: jpeg). |
| seed | No | Random seed for reproducible generation. |
| enable_sync_mode | No | API only — wait for the result and return it inline. |
| enable_base64_output | No | API only — return the image as a base64 string instead of a URL. |
How to Use
- Write your prompt — describe subject, style, lighting, mood, and any on-image text.
- Choose
size— pick an aspect ratio that fits your use case (e.g.,2048*2048for square,1536*2048for portrait,2048*1152for landscape). - Set
output_format— JPEG for compact files, PNG for lossless, WEBP for balance. - Set
seed(optional) — pin a number to reproduce exact results. - Run — submit the request and download the generated image.
Pricing
Flat rate per generated image.
| Output | Cost |
|---|---|
| Per image | $0.04 |
Best Use Cases
- Concept Art & Illustration — Translate text descriptions into detailed visual concepts.
- Marketing & Social Media — Produce eye-catching visuals for posts, ads, and campaigns.
- Product Visualization — Mock up product concepts and lifestyle imagery without a photo shoot.
- Storyboarding — Quickly visualize scenes and characters for creative projects.
- Editorial / Posters — Generate poster-grade images at high resolution.
Pro Tips
- Be specific about subject, style, lighting, and composition — HiDream-O1 follows detailed prompts well.
- For posters or banners, describe layout and any on-image text explicitly.
- Pin a
seedwhile iterating so you can A/B test prompt tweaks against a fixed baseline. - Match
sizeto your final use case (square for thumbnails, 16:9 for banners, 9:16 for mobile). - Use
pngwhen you need lossless quality; usejpegorwebpto keep file sizes small.
Notes
- Only
promptis required — every other field is optional. - Higher resolutions may slightly increase processing time.
- Ensure prompts comply with content guidelines.
