In short
How do I compare AI image models side by side?
Type one prompt in Create anything, Promly's Direct Kit, tick the models, and each one renders it at the same time, side by side. Promly runs 14 image models from OpenAI, Google, Black Forest Labs, Recraft, ByteDance, Ideogram and Grok. The default five-model run costs 9 Pixels with the volume discount; the 15 free Pixels cover it.

| You pick | Any of 14 models; five are ticked by default |
| Cost | Each model 1–5 Pixels an image; 15% off for 3 models, 25% for 4, 35% for 5 or more |
| Default run | Nano Banana 2 · Lite, Nano Banana 2.1, GPT Image 2.5, Flux, Nano Banana Pro: 9 Pixels |
| Free to start | 15 Pixels on sign-up, no credit card |

Real Promly runs: the same idea sent to every model at once. Flip through and judge for yourself. These four ran on 13 June 2026, on that day's line-up: Flux · Max has since become Flux 3, and Nano Banana 2 is now 2.1.

FAQ
Frequently asked questions
Which AI image models can I compare?
Fourteen, from seven providers: Flux · Fast, Flux, Flux 3 and Flux · Flex (Black Forest Labs); GPT Image 2.5, GPT · 2K and GPT · 4K (OpenAI); Nano Banana 2 · Lite, Nano Banana 2.1 and Nano Banana Pro (Google); Recraft V4.1; Seedream 5 (ByteDance); Ideogram; and Grok Imagine 2. Each costs 1–5 Pixels an image.
Do I have to write a prompt for this?
Yes. Direct is the power-user path: you write the prompt yourself and it goes to every model at once. It's the only place in Promly where you author a full image prompt from scratch; the Kits ask you a few questions and build it for you instead. A couple of Kits do take a sentence: Edit changes a photo from one instruction, and Animate takes a description of the motion.
Why compare models instead of picking one?
Different models win on different prompts: one nails photoreal, another nails text or style. Comparing on your own image is faster and cheaper than subscribing to each provider to find out.
Is it free?
Free to start: 15 Pixels on sign-up, no credit card. A comparison costs the sum of its models (1–5 Pixels each), minus 15% for 3 models, 25% for 4 and 35% for 5 or more. The default five-model run is 9 Pixels, so the free Pixels cover your first comparison. After that, Pixel packs start at 50 Pixels for $12 (they last 12 months), or plans at $7 a month for 30 Pixels.
Can I use what I make commercially?
Yes. Under Promly's Terms the images you generate are yours to use for any purpose, personal or commercial. The image models' own licence terms also apply.
