Ideogram V4 Text to Image and Image Edit API

Ideogram V4

Ideogram V4 generates high-quality images, posters, and logos from natural-language prompts with strong typography, sharp detail, and flexible output sizes. It supports both text-to-image and image-to-image workflows, with selectable resolution, aspect ratio, quality, and output format.

Why Choose This?

High-quality text-to-image generation — Turn natural-language prompts into polished visual outputs.
Image-to-image editing — Provide a source image and a prompt to restyle or edit it.
Strong design-oriented results — Create posters, public-art concepts, typography-led visuals, and graphic compositions.
Resolution and quality tiers — Pick 1k / 2k and low / medium / high to balance speed, detail, and cost.
Flexible aspect ratios — Generate square, portrait, landscape, ultra-wide, or vertical layouts.
Multiple output formats — Export results as jpeg, png, or webp.

Parameters

Parameter	Required	Default	Description
`prompt`	Yes	—	Text description of the image to generate or edit.
`image`	No	—	Optional input image for image-to-image editing. When provided, the model edits this image guided by the prompt.
`strength`	No	`0.65`	Image-to-image edit strength. Lower values keep the result closer to the source image; higher values allow stronger changes.
`resolution`	No	`1k`	Output resolution tier: `1k` or `2k`.
`aspect_ratio`	No	`1:1`	Output aspect ratio: `1:1`, `3:2`, `2:3`, `4:3`, `3:4`, `16:9`, `9:16`, `21:9`, `9:21`.
`quality`	No	`medium`	Quality tier: `low`, `medium`, or `high`.
`output_format`	No	`jpeg`	Output image format: `jpeg`, `png`, or `webp`.

How to Use

Write your prompt — Describe the subject, style, composition, lighting, and mood.
Upload an image (optional) — Provide image when you want to edit or restyle an existing image.
Adjust strength (optional) — Use strength to control how strongly the source image should be changed.
Choose output settings — Select resolution, aspect_ratio, quality, and output_format.
Submit — Generate the final image.

Example Prompt

A bold urban mural, "YOU ARE HERE" in oversized 3D block letters, glowing sunset gradient with turquoise accents, surrounded by blooming flowers, doves, and leafy branches flowing outward from the text, photorealistic exterior wall, mural paint texture, positive reflective message, energetic public art style

Best Use Cases

Poster and logo generation — Create typography-led posters, logos, and graphic concepts.
Marketing visuals — Generate polished images for campaigns, ads, social posts, and branded content.
Image-to-image restyling — Use an input image as the source and guide the edit with a prompt.

Creative ideation — Quickly explore different styles, layouts, and aspect ratios.

Pro Tips

Be specific about subject, material, composition, lighting, and mood.
If text inside the image matters, describe the exact wording and visual treatment.
Use 1:1 for square social graphics, 3:4 or 4:3 for posters, and 16:9 or 9:16 for widescreen or vertical layouts.
Use 2k + high for final assets where detail matters.
Use 1k + low for fast drafts.
For image-to-image, start around strength 0.5 to 0.65 for a guided edit, and raise it for stronger reinterpretation.

Ideogram v4 API — Quick start

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/ideogram-ai/ideogram-v4 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 Ideogram v4 below.

HTTP example

# Submit the prediction
curl -X POST "https://api.wavespeed.ai/api/v3/ideogram-ai/ideogram-v4" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY" \
  -d '{
    "prompt": "A cinematic shot of a city at sunset, soft golden light",
    "image": "https://example.com/your-input.jpg",
    "strength": 0.65,
    "resolution": "1k",
    "aspect_ratio": "1:1",
    "quality": "medium",
    "output_format": "jpeg"
}'

# 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("ideogram-ai/ideogram-v4", {
        "prompt": "A cinematic shot of a city at sunset, soft golden light",
        "image": "https://example.com/your-input.jpg",
        "strength": 0.65,
        "resolution": "1k",
        "aspect_ratio": "1:1",
        "quality": "medium",
        "output_format": "jpeg"
});

console.log(result.outputs[0]); // → URL of the generated output

Python example

# pip install wavespeed
import wavespeed

output = wavespeed.run(
    "ideogram-ai/ideogram-v4",
    {
    "prompt": "A cinematic shot of a city at sunset, soft golden light",
    "image": "https://example.com/your-input.jpg",
    "strength": 0.65,
    "resolution": "1k",
    "aspect_ratio": "1:1",

    "output_format": "jpeg"
}
)

print(output["outputs"][0])  # → URL of the generated output

Ideogram v4 API — Frequently asked questions

What is the Ideogram v4 API?

Ideogram v4 is a Ideogram model for image editing, exposed as a REST API on WaveSpeedAI. Ideogram V4 Text-to-Image and Image Edit API generates high-quality images, posters, logos, and marketing visuals from text prompts or reference images. It supports strong typography, sharp detail, flexible output sizes, 1K / 2K resolution tiers, and low / medium / high quality controls. 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 Ideogram v4 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/ideogram-ai/ideogram-ai-ideogram-v4.

How much does Ideogram v4 cost per run?

Ideogram v4 starts at $0.050 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 Ideogram v4 accept?

Key inputs: `prompt`, `image`, `aspect_ratio`, `resolution`, `output_format`, `quality`. 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/ideogram-ai/ideogram-ai-ideogram-v4.

How do I get started with the Ideogram v4 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 Ideogram v4 outputs commercially?

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