YouTube Thumbnails AI Generator
Generated on PixelDojo with Ideogram 4.0 Turbo. Produced by PixelDojo's generation pipeline.
You can make a YouTube thumbnail with AI by describing the scene and the exact words you want on it in one prompt, then generating with a model built for text rendering. We ran this on August 26, 2026 on Ideogram 4.0 Turbo for 1 credit, and the finished thumbnail came back in about 27 seconds with the headline spelled correctly on the first result. This page walks through the prompt structure that got the text right and the two follow-up steps that get a thumbnail ready to upload.

Ideogram 4.0 Turbo
One prompt, one thumbnail, August 26, 2026: 1 credit on Ideogram 4.0 Turbo, about 27 seconds, the headline text correct on the first try.
Why Choose Pixel Dojo for YouTube Thumbnails
Professional-quality results with cutting-edge AI technology
1 credit per thumbnail
Ideogram 4.0 Turbo is the cheapest tier in the Ideogram 4.0 family and still handled a full headline correctly.
About 27 seconds, measured
Timed from request to finished file on August 26, 2026, fast enough to try a few headline variations in one sitting.
The text came out right the first time
No misspelled letters and no doubled words, the two failure modes that usually force a retry on a text-heavy prompt.
How It Works
Three steps, one thumbnail, ready for the upload screen:
Write the headline into the prompt itself
Name the scene and put the exact words you want on the thumbnail in quotes inside the prompt. Ours asked for a shocked man pointing at a rising chart with bold yellow lettering reading 'THIS CHANGES EVERYTHING', on Ideogram 4.0 Turbo for 1 credit. It came back in about 27 seconds as a 2560 by 1440 image with every letter spelled correctly and no garbled type, the single hardest part of a thumbnail prompt.
Pick a model built for text, not just images
General image models often mangle on-image text past a few words. Ideogram 4.0 is built around accurate text rendering, which is why the headline came out clean in one pass with no retries or manual lettering.
Crop and export at the platform size
YouTube thumbnails display at 1280 by 720 in most placements. Our output was 2560 by 1440, the same 16:9 ratio at double the pixel count, so cropping or downscaling to spec loses nothing that matters on screen.

Common Questions
Everything you need to know about YouTube Thumbnails
What does an AI YouTube thumbnail cost?
1 credit on Ideogram 4.0 Turbo, the tier we used. The Balanced tier is 2 credits and the Quality tier is 3 credits if you want a further pass on detail. The text rendering approach is the same across all three.
How do I get the text to render correctly?
Put the exact words in quotes inside the prompt, next to a description of the scene around them. Ours asked for bold yellow lettering reading a specific six word phrase and it came back spelled correctly with no retry.
How fast is it?
About 27 seconds in our August 26, 2026 run, from the prompt to the finished 2560 by 1440 file.
What size should I export for YouTube?
YouTube thumbnails display at 1280 by 720. Our output was already 16:9 at 2560 by 1440, so a straight downscale fits the spec without cropping anything out.
Can I make several headline options at once?
Yes, run the same scene prompt with a different quoted headline each time. Each generation is priced and timed independently, so a batch of five headline options at 1 credit each is 5 credits total.
How do I call this from the API?
POST to /api/v1/models/ideogram-4/run with your API key, a prompt and tier set to turbo. It is the same key and request shape as every other model in the catalog.
