What is the HiDream I1 API?

HiDream I1 is a three-variant text-to-image family exposed on Muapi. Every listed endpoint accepts a required prompt plus optional width, height, and num_images values; no source image is required. Width and height range from 128 to 2048 pixels in steps of 64, while num_images accepts 1 to 4.

Use HiDream I1 Fast for quick previews and interactive applications, Dev for experimentation and custom creative workflows, and Full for detailed production assets. Pricing is per generated image, so a request for multiple images is charged once for each output.

HiDream I1 API capabilities

Prompt-to-image generation

Turn a text prompt between 2 and 3000 characters into one or more generated images.

Fast preview workflows

Use HiDream I1 Fast when rapid previews and responsive creative iteration matter most.

Flexible image dimensions

Set width and height independently from 128 to 2048 pixels, provided each value is divisible by 64.

Batch image outputs

Request 1 to 4 images in one call and track the per-image charge through the shared Muapi task response.

Quick start — HiDream I1 API

Submit a HiDream image task with your Muapi key, receive a request ID, and poll the shared predictions endpoint for the generated image URL.

1. Submit a HiDream I1 job

curl -X POST https://api.muapi.ai/api/v1/hidream_i1_fast_image \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt":"A sunlit reading nook with plants and a linen armchair","width":1024,"height":1024,"num_images":1}'

# Response: {"request_id":"REQUEST_ID"}

The example calls the live hidream_i1_fast_image endpoint. Use the Dev or Full endpoint when you need that variant.

2. Poll the result

curl https://api.muapi.ai/api/v1/predictions/REQUEST_ID/result \
  -H "x-api-key: YOUR_API_KEY"

Poll until the task completes, then read the generated image from the result response.

HiDream I1 API FAQ

Which HiDream I1 endpoints are available?

Muapi lists three live endpoints: hidream-i1-fast, hidream-i1-dev, and hidream-i1-full. All are text-to-image routes with the same prompt, dimensions, and num_images input pattern.

What inputs does HiDream I1 require?

The prompt is required and can be 2 to 3000 characters. Width and height are optional values from 128 to 2048 that must be divisible by 64, and num_images can be set from 1 to 4.

What is the difference between Fast, Dev, and Full?

Fast is optimized for quick previews and rapid iteration, Dev is suited to experimentation and custom workflows, and Full is the high-fidelity choice for detailed production images.

Can I generate multiple HiDream images in one request?

Yes. Set num_images from 1 to 4. Each generated image is billed separately, so a four-image request incurs four times the listed per-image rate.

How much does HiDream I1 cost on Muapi?

HiDream I1 Fast costs $0.008 per generated image, Dev costs $0.02 per image, and Full costs $0.04 per image. The charge scales with num_images.
