AI Image Generation, Without the Friction
Type what you want. Pick a model. Get an image. That's really it. No account, no watermark, no waiting around.
Behind the scenes we're running Google DeepMind's latest image models alongside flagship models from Black Forest Labs, ByteDance, OpenAI, Alibaba and Meta, so the output quality is genuinely good whichever you pick. You get control over aspect ratio, resolution, and format without needing to know anything about how the models actually work. It's the kind of tool that's useful whether you're mocking something up quickly or actually care about the final result.
Which Model Should You Use?
What's the difference between the models?
The Nano Banana models run on Google DeepMind technology. The rest come from Black Forest Labs, ByteDance, OpenAI, Alibaba and Meta. They're built for different things. Here's a quick look at what each one produces so you can pick the right one without having to guess.
travel_explore Nano Banana 2
The quick one. It pulls from Google Search at generation time, which helps when you're asking for something specific, like a real place, a historical period, that kind of thing. Text rendering is noticeably better too, with support for multiple languages. You can feed it up to 14 reference images if you're trying to composite something complex.
workspace_premium Nano Banana Pro
The one to reach for when quality actually matters. It outputs natively at 4K, handles fine typography cleanly, and does a better job with lighting and spatial reasoning. Takes a bit longer than the Flash models, but the difference in output is usually worth it for anything you're planning to actually use.
The Models From Other Labs
Google isn't the only lab making good image models, so the dropdown also carries five from other labs. Same prompt box, same aspect ratio picker, same download button. Here's what each one is for.
photo_camera FLUX.2 Max
Black Forest Labs' newest flagship and the most photographic of the set. Skin, fabric, weather and lens blur come out looking like a camera took them. Up to 4 megapixels in any of the nine aspect ratios.
translate Seedream 5.0 Pro
ByteDance's flagship. Its party trick is text: it renders readable lettering in 14 languages, so signage, packaging and posters with non-English copy come out right. It also copes well with crowded scenes where a lot has to fit in frame. Up to 4 megapixels, about a minute per image.
draw GPT Image 2
OpenAI's image model, and the one to use when the words matter. Labels, diagrams, menus, book covers: it follows long, fussy instructions more faithfully than anything else on this page and rarely misspells. The trade-off is time. Expect a minute or two per image.
speed Qwen Image 3
Alibaba's model. A solid all-rounder with decent English and Chinese text, and the most economical of the non-Google options, which is why it's here. It can be slow at busy times.
grid_on Muse Image
Meta's text-to-image model. Strong on fine detail that has to be exactly right: charts, plots, QR codes, small print. Same nine aspect ratios as FLUX.
At-a-Glance Model Comparison
lightbulb Worth knowing
You don't have to commit to one model. A workflow that works well: generate your base image with Nano Banana 2, then bring it into Nano Banana Pro to edit specific parts, add text, or push it to 4K.
How to Generate an AI Image
It takes about a minute from blank prompt to finished image. Here's how it works.
- 1
Write a Prompt Type a description of what you want to see. The more specific you are about subject, style, lighting, and mood, the better the result.
- 2
Choose a Model Pick from seven models: Nano Banana 2 and Nano Banana Pro from Google, GPT Image 2 from OpenAI, FLUX.2 Max, Seedream 5.0 Pro, Qwen Image 3 or Muse Image. Each has a different strength, whether that is speed, typography, photorealism or 4K output. More on that above.
- 3
Set the Aspect Ratio Square works well for social posts, widescreen for desktop wallpapers, portrait for phone screens.
- 4
Tweak the Settings Open More Settings if you want to change the resolution or output format (JPEG, PNG, WebP). Otherwise the defaults are fine.
- 5
Generate Hit the button. Nano Banana and FLUX results usually land in 20 to 40 seconds; GPT Image 2 and Qwen Image 3 can take a minute or two. Download it or open it full size from the result panel.
Frequently Asked Questions
Is it free?
Yes, completely. The Nano Banana models need no account at all, just type a prompt and go. The other five need a free sign-in, mainly so we can keep an eye on what they cost us. No subscription, no credit card either way.
Which model should I pick?
If you're not sure, start with Nano Banana 2. It's quick and handles most prompts well, and its search grounding helps when you're asking for a real place or a specific thing. For anything with words in it, a poster, a label, a diagram, GPT Image 2 gets the lettering right more often than anything else here. FLUX.2 Max is the most photographic of the set. Seedream 5.0 Pro is strong on busy scenes and non-English text. Qwen Image 3 is the budget option and still decent. Nano Banana Pro at 4K is the one for anything you'll print or publish.
How do I write a better prompt?
Be specific. Instead of "a dog in a park", try "a golden retriever sitting on a bench in a sun-drenched London park, shallow depth of field, film photography style". Subject, setting, lighting, and style all make a difference. Our Prompt Guide covers this in more detail.
What aspect ratios and formats are available?
Square (1:1), landscape (16:9), portrait (9:16), and several others. Output formats are JPEG, PNG, and WebP. Resolution options depend on the model. Nano Banana Pro goes up to 4K, and the other models render at up to 4 megapixels.
Can I download the images?
Yes. Hit the download button in the top corner of the result, or open it full size in a new tab. The images are yours to use however you like.
Can I use the images commercially?
Yes. Images you generate on NeonSnap are yours to use however you like, including for commercial projects. There are no watermarks and no licensing restrictions on the output.
How long does it take to generate an image?
It depends on the model. Nano Banana 2, Nano Banana Pro, FLUX.2 Max and Muse Image usually come back in 20 to 40 seconds. Seedream 5.0 Pro takes about a minute. GPT Image 2 and Qwen Image 3 are the slow ones, often a minute or two, because they do more work per image. The page keeps the spinner up until it's done, so there's no need to refresh.
