Hidream O1 Image Dev Text to Image | High-Quality Text-to-Image API

HiDream-O1-Image Dev (Text-to-Image)

HiDream-O1-Image Dev is the distilled variant of HiDream-O1-Image. It keeps the unified, single-native-model architecture (text-to-image, image editing, and subject-driven personalization) and the same up to 2K (≈2048×2048) resolution ceiling, but is tuned for fast, low-step inference — making it the best pick when you need speed and lower cost without giving up the HiDream-O1 look.

Why Choose This?

Distilled for speed — Fewer denoising steps than the full model, which means lower latency per image.
Lower cost — Half the price of the full HiDream-O1-Image model, ideal for high-volume generation, drafts, and rapid iteration.
Same unified architecture — One native model handles text-to-image, edit, and personalization. No external adapters or pipelines.
High-resolution output — Generate detailed images up to ~2048×2048 with strong composition and 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.
Reproducibility — Use a fixed seed to recreate exact results.

Parameters

Parameter	Required	Description
prompt	Yes	Text description of the image you want to generate.
size	No	Output image size as `WIDTHHEIGHT` (default: `20482048`). 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*2048 for square, 1536*2048 for portrait, 2048*1152 for 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 — half the price of the full HiDream-O1-Image model.

Output	Cost
Per image	$0.02

Best Use Cases

High-volume generation — Bulk content creation where per-image cost and latency matter.
Drafts & rapid iteration — Quickly explore prompt variations before committing to the full model.
Concept Art & Illustration — Translate text descriptions into detailed visual concepts.
Marketing & Social Media — Produce eye-catching visuals for posts, ads, and campaigns.
Storyboarding — Quickly visualize scenes and characters for creative projects.
Product Visualization — Mock up product concepts and lifestyle imagery.

Dev vs. Full — Which to Pick?

	HiDream-O1-Image Dev	HiDream-O1-Image (Full)
Speed	Faster (distilled, fewer steps)	Standard
Cost / image	$0.02	$0.04
Quality ceiling	High	Highest
Best for	Drafts, batches, low-cost generation	Final, hero images

Use Dev when you're iterating, batching, or cost-sensitive. Switch to the full model for the very best fidelity on hero shots.

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 seed while iterating so you can A/B test prompt tweaks against a fixed baseline.
Match size to your final use case (square for thumbnails, 16:9 for banners, 9:16 for mobile).
Use png when you need lossless quality; use jpeg or webp to keep file sizes small.

Notes

Only prompt is required — every other field is optional.
Higher resolutions may slightly increase processing time.
Ensure prompts comply with content guidelines.

Hidream O1 Image Dev Text To Image API — Quick start

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/wavespeed-ai/hidream-o1-image-dev/text-to-image with your input as JSON. The endpoint returns a prediction id; poll the prediction endpoint until status flips to completed, then read the output URL from data.outputs[0]. Examples for Hidream O1 Image Dev Text To Image below.

HTTP example

# Submit the prediction
curl -X POST "https://api.wavespeed.ai/api/v3/wavespeed-ai/hidream-o1-image-dev/text-to-image" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY" \
  -d '{
    "prompt": "A cinematic shot of a city at sunset, soft golden light",
    "size": "2048*2048",
    "output_format": "jpeg",
    "enable_sync_mode": false,
    "enable_base64_output": false
}'

# Response includes a prediction id. Poll for the result:
curl -X GET "https://api.wavespeed.ai/api/v3/predictions/{request_id}/result" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY"

# When status is "completed", read the output from data.outputs[0].

Node.js example

// npm install wavespeed
const WaveSpeed = require('wavespeed');

const client = new WaveSpeed(); // reads WAVESPEED_API_KEY from env

const result = await client.run("wavespeed-ai/hidream-o1-image-dev/text-to-image", {
        "prompt": "A cinematic shot of a city at sunset, soft golden light",

Hidream O1 Image Dev Text To Image API — Frequently asked questions

What is the Hidream O1 Image Dev Text To Image API?

Hidream O1 Image Dev Text To Image is a WaveSpeedAI model for image generation, exposed as a REST API on WaveSpeedAI. HiDream-O1-Image Dev is a distilled, faster variant of the unified HiDream-O1-Image model — same native text-to-image / edit / personalization architecture at up to 2K, optimized for low-step inference and lower cost. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing. You can call it programmatically or try it from the playground above.

How do I call the Hidream O1 Image Dev Text To Image API?

POST your input parameters to the model's REST endpoint (shown in the API tab of this playground) with your WaveSpeedAI API key in the Authorization header. Submission returns a prediction ID; poll the prediction endpoint until status flips to "completed", then read the output URL from the result. The playground generates a ready-to-paste code sample in Python, JavaScript, or cURL for whatever inputs you've set. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/wavespeed-ai/hidream-o1-image-dev-text-to-image.

How much does Hidream O1 Image Dev Text To Image cost per run?

Hidream O1 Image Dev Text To Image starts at $0.020 per run. That figure is the base price — the final charge scales with the parameters you set in the form (output size, length, count, references, or whatever knobs this model exposes), so a higher-quality or larger output costs more than a minimal one. The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.

What inputs does Hidream O1 Image Dev Text To Image accept?

Key inputs: `prompt`, `size`, `enable_base64_output`, `enable_sync_mode`, `output_format`. The full JSON schema (types, defaults, allowed values) is rendered above the Generate button and mirrored in the API reference at https://wavespeed.ai/docs/docs-api/wavespeed-ai/hidream-o1-image-dev-text-to-image.

How do I get started with the Hidream O1 Image Dev Text To Image API?

Sign up for a free WaveSpeedAI account to claim starter credits, copy your API key from /accesskey, then call the endpoint shown in the API tab of the playground. The playground also auto-generates a code sample in Python, JavaScript, or cURL for the parameters you've set.

Can I use Hidream O1 Image Dev Text To Image outputs commercially?

Commercial usage rights depend on the model's license, set by its provider (WaveSpeedAI). The license summary appears on the model card above; see WaveSpeedAI's Terms of Service for platform-level conditions.
