Which AI image generator should you use?
By Chatday Editorial Team ·
“Make me a picture of a cat in a spacesuit.” Easy, right? You type it, something appears, done. Except the tool you happened to pick quietly decides whether that cat looks like a real photo, a polished cartoon, or a melted nightmare with seven toes and a sign that says “SPCAE.”
Here’s the thing most people miss: there isn’t one “AI image generator” anymore. There are about half a dozen serious ones, and they are weirdly, wildly good at different jobs. One nails readable text on a poster. One can edit a photo you already have without redrawing the whole thing. One is just fast. Pick the right one for the task and you look like you hired a designer. Pick the wrong one and you get that glossy, plasticky “AI look” everyone can spot from across the room.
This is the plain-English map of who wins at what. No jargon, no sample galleries you have to squint at. Just: for this thing, use that one.
The main players, in one line each
- Nano Banana (Google): the current crowd favourite. Brilliant at editing real photos and keeping a face or character consistent across several images.
- GPT Image (OpenAI): the friendly default. You describe what you want in plain language and it figures out the rest.
- FLUX (Black Forest Labs): the photorealism specialist, great when a shot needs to look like it came out of an actual camera.
- Recraft: the designer’s pick. It handles text, logos and clean layouts, and can even hand you a proper vector file.
- Imagen and Grok Imagine: the speed merchants, handy when you just want a pile of quick options to choose from.
Now let’s break it down by what you actually want to do.
Best for editing a photo you already have: Nano Banana
This is the biggest shift of 2026, and it’s the one most people haven’t caught up with yet. Old image AI could only invent pictures from scratch. The newer wave can take a photo you already own and rework it.
Want to swap the background, change someone’s outfit, turn a flat midday snapshot into a golden sunset, or put the same person into five different scenes for a set? Nano Banana, now in its Pro version, does this better than anything else around. It can rebuild an existing image from new angles while keeping the subject recognisable, the sort of thing that used to mean an hour of fiddling in Photoshop. Reviewers have been calling it the standout image tool of the year, and editing is exactly why.
If your goal is specifically rescuing old, faded or torn family photos, that’s a slightly different craft, and we walked through it step by step in how to restore old photos with AI.
Best for text and logos in the image: Recraft
For years this was AI’s most embarrassing weak spot. It would paint a gorgeous café scene and then spell “COFEE” on the awning. That era is basically over.
Recraft is built for designers, not just dreamers. It renders clean headlines, product labels and logos, and crucially it can export a real scalable vector, so you can blow the result up to billboard size without it turning into a blurry mush. That makes it the natural pick for anything heading toward print or branding.
Nano Banana Pro has quietly become excellent here too. It now spells text reliably, even across many languages, so if you only want to remember one tool, it covers this job as well.
Best for a true-to-life photo look: FLUX (and Imagen)
When you need something that could honestly pass for a photograph, a product on a kitchen counter, a portrait, a landscape, FLUX is the specialist. It leans into realistic light, texture and depth instead of that overly smooth, illustrated feel.
Google’s Imagen is the fast cousin for the same kind of work. When you’d rather spin through twenty quick variations than perfect a single frame, its speed makes it a comfortable everyday workhorse.
Best for “just make me something, fast”: GPT Image
If you don’t want to think about any of this, GPT Image is the forgiving one. You describe the picture the way you’d describe it to a friend, sloppy grammar and all, and it does a genuinely solid job without much coaxing.
The trade-off: its results can carry that slightly glossy, too-perfect sheen that reads as “yep, an AI made this.” So it’s a brilliant starting point and a poor finish line. Great for a first idea you then refine elsewhere.
Best for illustrations, art and concepts: it’s a tie
If you want a styled illustration rather than a photo, a storybook scene, a comic panel, a moody concept sketch, most of these can do it, and taste matters more than benchmarks. Grok Imagine is quick and playful for casual art, Recraft shines on clean flat-style illustration, and GPT Image is happy to riff on a vibe. Try the same prompt in two of them and keep the one whose style you like. There’s no objective winner here, only the look you’re after.
The cheat sheet
| If you want to… | Best pick | Why |
|---|---|---|
| Edit or restyle a photo you already have | Nano Banana | Reworks real images, keeps faces consistent |
| Put readable text or a logo in the image | Recraft | Built for type and design, exports vectors |
| Get a true-to-life photographic look | FLUX | Photorealism specialist |
| Generate lots of options fast | Imagen / Grok Imagine | Speed over everything |
| Just describe it and get a good result | GPT Image | Easiest and most forgiving |
A couple of things to watch for
A few honest caveats, because nobody mentions these. Hands and fine details still trip every model up now and then, so zoom in before you trust a result. The “AI sheen” is real, and a quick edit pass (or a more photo-real model like FLUX) usually fixes it. And if you’re recreating a real, recognisable person, be thoughtful: just because a tool can copy a likeness doesn’t always mean you should publish it.
Two prompts to try right now
Copy one, tap the button, and swap the bits in brackets for your own.
So which one should you actually pick?
If you only want to remember a single name, make it Nano Banana. It’s the best all-rounder of 2026 and the only one that comfortably edits real photos. Reach for Recraft the moment you need words or a logo in the picture, lean on FLUX when you want something that could pass for a real photograph, and keep GPT Image around as the easy button for quick, casual stuff.
The genuinely annoying part used to be that each of these lived behind its own app, its own login and its own subscription. So testing two against each other meant signing up twice and paying twice.
That’s the bit Chatday quietly fixes: the main image generators sit side by side in one place, so you can fire the same idea at a few of them and keep the best result. No extra logins, no second bill.
Bottom line
Stop hunting for the single best AI image generator. It doesn’t exist, and chasing it usually means missing the one tool that would have nailed your specific picture. Learn the rough map instead, Nano Banana to edit, Recraft for text, FLUX for realism, GPT Image for easy, and you’ll get better images with a lot less frustration.
