Frequently Asked Questions
What is the best AI model for flat design images?
For flat design, we recommend Ideogram V3 Turbo. It excels at text in images, logos, posters, marketing materials and typically generates results in 10-15s. That said, you can try all 4 models to see which gives you the best results for your specific prompt.
Is Thumb AI free to use for flat design?
Yes. You get 1 free credit every month to try it out. Each credit generates one image. If you need more, the Creator Pack gives you 30 credits for $18 as a one-time purchase. No subscription, no recurring charges, and your credits never expire.
What image sizes and formats can I download?
You can generate images in 7 different aspect ratios including 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, and 2:3. Downloads are available in PNG, JPG, or WebP format at full resolution.
How long does it take to generate flat design images?
It depends on the model you choose. Z-Image Turbo is the fastest at 5-8 seconds. Seedream 4.5 and Ideogram V3 take 10-15 seconds. Flux 1.1 Pro takes 20-30 seconds but produces the most detailed results.
How do I get the best flat design results?
Be specific in your prompt. Instead of just saying "a landscape," describe the lighting, colors, mood, and composition you want. Use the prompt enhancer to automatically improve your description. If a model supports negative prompts, use them to remove unwanted elements.
