Text to image questions, answered.
What is free, which models are available, and what happens when a render fails.
What is a text to image AI generator?
It turns a written description into a picture. You type what you want, choose a model, and the model paints it: a product shot, an illustration, a poster or a portrait. With an uploaded photo it also does image to image, which keeps a face or a product and rewrites the rest of the frame.
Is the AI image generator free?
The first image of the day is free for every visitor, no account needed, and it resets at midnight. That free image uses the free model at its default resolution. Anything beyond it, including other models, 2K and 4K output, and batches of two or four, is paid from credits.
Do I need an account to generate an image?
Not for the daily free image. An account is only needed to keep generating after it, to use the paid models, or to keep your gallery on another device. Signing in does not raise the daily allowance, it moves the images you already made onto the account.
Which AI image models can I choose?
Nano Banana 2.1, the Gemini 3 image models, GPT Image 2, 2.5 and 2.6, FLUX 2 Pro and FLUX Kontext, Seedream 4.0 through 5.0 Pro, Qwen Image 3.0, Grok Image 2.0 and Vidu Q3. Entry models are for finding the prompt, premium ones are for the image you publish, and every card shows its lowest price before you pick it.
How do I write a good text to image prompt?
Name the subject, the medium, the details and the mood, for example "portrait of a woman in a linen blazer, studio photo, softbox from the left, muted palette". Stay under about 60 words, put text that must appear in the picture in quotes, and change one element per re-render so you can tell what worked.
What is image to image?
You upload a photo and describe the change instead of starting from nothing: a new background, another style, the product in a different room. The model keeps the subject and redraws the rest. How many references you can attach depends on the model, from one on FLUX Kontext up to fourteen on Nano Banana 2.1.
Which aspect ratios can I choose?
1:1 for feeds, 4:3 and 3:4 for listings and print, 16:9 for banners, 9:16 for stories and phone wallpaper. Only the ratios the selected model actually supports are shown, so the choice you see is the choice that renders.
Can I generate 2K or 4K images?
Yes, where the model supports it: Nano Banana 2.1, Gemini 3 Pro Image, FLUX 2 Pro, GPT Image 2 VIP and Vidu Q3 offer 2K, and Nano Banana 2.1, Gemini 3 Pro and Vidu Q3 go up to 4K. Higher resolution costs more credits because the provider charges more, and each option is priced before you submit.
How many images can I generate at once?
One, two or four. Each image is billed separately and the button always shows the total for the batch. Guests can render the single free image; batches of two or four need an account, since only one image a day is free.
Can the AI put text in the image?
Short text, yes. Nano Banana, GPT Image and Seedream render a headline, a label or a two word sign with usable spelling. Put the wording in quotes, say where it goes and keep it short. Long paragraphs, small print and logos still need an editor.
Which art styles are supported?
Photoreal, product photography, illustration, anime, oil and watercolour, 3D render, pixel art and line drawing, among others. Style is a phrase in the prompt rather than a dropdown, so it combines freely with the subject and the ratio.
How long does an image take?
Typically five to thirty seconds. Batches of four and 4K output take the longest, and the job keeps running if you close the tab, so you can come back to it in the panel or in your history.
What happens if a render fails?
The credits for that image are returned automatically, usually within a minute. The failed card stays in the panel so you can read the message and try again with a shorter prompt or a different model.
How much does an image cost?
From 2 credits on the cheapest model, up to around 10 for a 4K render on a premium one. The exact price for the model and resolution you picked sits on the Create button, and a failed render is refunded.
Can I use the images commercially?
You can use what you generate, subject to the Terms of Use and the terms of the model provider. Some providers restrict specific uses and a few restrict resale of the raw output, so check the licence before a paid campaign.
Who can see the images I make?
Only you. Uploads are re-encoded with metadata stripped, results are stored privately and served through routes tied to your own device or account, and deleting an image removes the stored file as well as the history entry.
What format do the images download in?
JPG at the resolution you rendered, up to 4K where the model supports it. The prompt and settings stay attached to each image in the panel, so you can tell two similar versions apart later.
Can I generate images on a phone?
Yes. The studio is a normal web page, uploads come from the camera roll and the render runs on the server. The phone only has to hold the page, so a weak connection slows the upload, not the model.
