Images turned into shots in Root
What Ideogram v3 does on Root
- Makes an image from a prompt, with the words you put in quotes written into the picture.
- Makes 1:1, 16:9, 9:16, 4:3 and 3:4 images.
- Takes reference images to guide the look.
- Reads a negative prompt sent by API or from Claude and ChatGPT, so you can rule out things such as extra text.
- Saves every image to your project, next to the shots it belongs to.
Image models for words in the picture
Root runs more than one model that handles text well. The price is for one image at the size shown, in dollars. 100 credits is $1.
| Model | Best for | Price of one image |
|---|---|---|
| GPT Image 2 | Sharp text in the image and close instruction-following. | $0.25 at 1K |
| GPT Image 2.5 Flare | Everyday images at a lower price, with the same sharp text. | $0.07 at 1K |
| Ideogram v3 | Words and lettering inside the image: posters, titles, signs. | $0.07 |
How to get the lettering right
- Quote the words. Write the exact text in quotes: a sign that says “OPEN LATE”. Keep each line of text short.
- Say where it goes. Name the place: across the top, centred at the bottom, on the shop window.
- Describe the type. Say what the letters look like: bold condensed capitals, hand-painted script, white on red.
- Rule things out. By API or from Claude and ChatGPT, list what you don't want in the negative prompt, such as extra words or a frame. In the Root app, say what you want instead: “a plain background”.
Ideogram v3 by API
One request makes one image and saves it to the project you name.
curl https://root.film/api/v1/generations \
-H "Authorization: Bearer rfk_your_key" \
-H "Content-Type: application/json" \
-d '{"model":"ideogram-v3","project_id":"YOUR_PROJECT_ID",
"input":{"prompt":"A film festival poster, the words NIGHT SHIFT in bold white capitals across the top",
"negative_prompt":"extra text, border",
"aspect_ratio":"3:4"}}'- Make an API key in Root under Settings, then API, and choose a daily spending limit for it.
- The finished file is saved to the project you name, so your team sees it in the app too.
- Send an Idempotency-Key header and a retry never charges twice.

Ideogram questions
How much does Ideogram cost on Root?
One Ideogram v3 image is $0.07 on Root, with or without reference images. The price is shown before you run it, and it comes out of the same credits as every other model.
What is Ideogram good at?
Words inside the picture: posters, titles, signs, labels and logos with clear lettering. Put the exact words in quotes in your prompt, and keep them short.
Can Ideogram edit an image I already have?
Not on Root. Ideogram v3 makes new images and can take reference images to guide the look, but it does not change an image you give it. To change the words on an existing image, use an edit model such as Nano Banana Pro or GPT Image 2.5 Sunburst.
What shapes can Ideogram make?
1:1, 16:9, 9:16, 4:3 and 3:4. Pick the shape in the settings rather than in the prompt.
Is there an Ideogram API on Root?
Yes. Make an API key in Root and send the model id ideogram-v3 to the generations endpoint with a prompt and a project. The image is saved to that project.
Can I use Ideogram from Claude or ChatGPT?
Yes. Connect Root to Claude or ChatGPT and ask for an Ideogram image in the chat. It is priced and saved to your project the same way as in the app.
Does Ideogram take a negative prompt?
Yes, by API or from Claude and ChatGPT: send a negative prompt with what you don't want, such as extra text or a border. The Root app has no negative prompt box, so there, say what you want instead.
Can I try Ideogram for free?
For a month, yes. The first month of Root's Beginner plan is free and comes with 650 credits, enough for 92 Ideogram v3 images. After that the plan is $9 a month, and you can cancel whenever you like.
