Cheapest AI Image Generators Tested: 14 Models, From a Third of a Cent an Image
The same product ad on 14 low-cost AI image models, from FLUX.1 schnell at $0.003 to MAI Image 2.5 Pro at 12.5 cents. See every result, what it cost, and which ones get the headline and label right.
Short answer: FLUX.3 klein at under a cent an image was the pick of this test, with a correct headline and a correct label. Seedream 5.0 Flash at 1.8 cents was the cleanest layout, at the highest resolution of the group. Text in images is close to solved at this price: all fourteen spelled the headline and the brand name, and only one made a word mistake.
Here's every result as it came out.
How we tested
Same prompt as our first test of eleven image models, sent word for word on November 1, 2026. One image each, 4:5 where the model offers it, at the default size. FLUX.1 schnell, Grok Imagine 2.0 and MAI Image 2.5 Pro don't do 4:5, so they got 3:4. No retries.
A 4:5 social ad photo. A matte amber glass bottle of cold brew coffee stands on a sunlit marble kitchen counter, condensation beading on the glass. The bottle's label reads "NORTHBEAN COLD BREW". Across the top of the image, a bold clean sans-serif headline reads "Your mornings, sorted." Soft natural window light, realistic product photography, shallow depth of field.
The results
Price vs quality, image by image
The cost is what each render cost us, from our usage ledger. Per thousand is the same number times a thousand, which is how you should think about it if you're testing variations.
| Model | This image | Per 1,000 | Delivered | Headline | Notes |
|---|---|---|---|---|---|
| FLUX.1 schnell | $0.003 | $3 | 768 x 1024 | Right, hard to read over the window | Made COLD BREW the big type, with the brand name small. Good for sketches. |
| FLUX.2 klein | $0.0057 | $5.74 | 896 x 1120 | Right | Simple, clean label printed on the glass. |
| Recraft V4.1 Flash | $0.007 | $7 | 896 x 1152 | Right, low contrast | Moody look. The label became one thin strip. |
| Krea 2 Turbo | $0.0077 | $7.66 | 896 x 1120 | Right, big and bold | Good layout, and the small print on the label is filler. |
| FLUX.3 klein | $0.009 | $9 | 896 x 1120 | Right | The most believable label of the cheap group. Best value in the test. |
| Seedream 5.0 Flash | $0.018 | $18 | 1536 x 1920 | Right | The largest image and the tidiest layout, with a plain white label. |
| Qwen-Image | $0.02 | $20 | 896 x 1120 | Right, colour changes mid-word | Added a small logo of its own. |
| Krea 3 | $0.024 | $24 | 896 x 1120 | Right | Clear and plain, with the label readable at a glance. |
| Seedream 4.0 | $0.03 | $30 | 896 x 1120 | Right | Solid. The newer, cheaper Flash beat it here. |
| Nano Banana 2 Lite | $0.0336 | $33.62 | 928 x 1152 | Wrong: "sorted." appears twice | The most styled scene and the richest label, and the only spelling slip in the group. |
| GPT Image 2.5 Flare | $0.042 | $41.60 | 896 x 1120 | Right | Polished, with an invented mountain mark on the label. |
| MOSS Image | $0.05 | $50 | 896 x 1120 | Right | Printed the name directly on the glass and added a logo. |
| Grok Imagine 2.0 | $0.06 | $60 | 864 x 1152 | Right, big and bold | A strong poster layout. xAI lists this model at $0.04 an image on its own API, so this render cost us more than its list price. |
| MAI Image 2.5 Pro | $0.125 | $125 | 768 x 1024 | Right | Warm and appetising, with the best light in the set. You pay for that. |
Two models couldn't take this exact job. Ideogram v4 Fast's content filter refused the prompt, and GPT Image Mini doesn't offer 4:5.
Which to use
- Testing lots of ideas: FLUX.3 klein or FLUX.2 klein. A hundred variations costs about a dollar.
- An image you might actually run: Seedream 5.0 Flash at this price, or step up to the Nano Banana 2.1 and GPT Image 2.5 results from our first test.
- Your real product: a prompt invents the packaging. Attach your own photo, as in our AI product photo generator, so the label is yours.
- Always read the headline. One word repeated is the sort of slip you only catch once it's live.
