What this comparison is based on
Most comparisons of AI image generators are opinion with a star rating attached. This one starts from a fixed corpus snapshot: 9,667 published LocalBanana gallery items on August 5, 2026. Each item has a recorded model label; 9,599 also have an English-first canonical prompt longer than 20 characters (falling back to Chinese only when English is blank). That lets us ask a narrower question — not "which model is best," but what kinds of requests appear in the published examples associated with each model.
Here is what the snapshot says. The image column counts all items in each row; percentages use that model's eligible prompts.
| Model | Images | Prompts asking for text / typography | Prompts with camera cues (shot on, 85mm, f/1.4, film grain) | Prompts asking for illustration / anime |
|---|---|---|---|---|
| Midjourney | 4,305 | 7.9% | 9.6% | 17.0% |
Nano Banana Pro (banana-pro) | 3,305 | 21.8% | 45.5% | 19.4% |
| GPT Image | 2,043 | 51.7% | 28.0% | 36.2% |
Three findings fall straight out of it:
51.7%
2.4× Nano Banana, 6.5× Midjourney
45.5%
4.7× Midjourney
7.9%
the lowest of the three by a wide margin

September 2026: Google Nano Banana vs GPT Image 2 and Midjourney V8.2
Product names move faster than durable comparison pages. These are the current options most relevant to this comparison, verified on September 3, 2026:
| Current option | Exact model or version | Provider's current positioning |
|---|---|---|
| Nano Banana 2 | gemini-3.1-flash-image | High-efficiency image generation and editing for speed and volume |
| Nano Banana Pro | gemini-3-pro-image | Studio-oriented generation and editing for complex design, layouts and high-resolution work |
| GPT Image 2 | gpt-image-2 | Fast, high-quality generation and editing with flexible sizes and high-fidelity image inputs |
| Midjourney V8.2 | --v 8.2 | The current default, focused on aesthetics, image quality, personalisation and a new Edit Model |
| Grok Imagine Image 2.0 | grok-imagine-image-2.0 | Generation and precise editing, with typography, layout and multi-reference workflows |
Google also lists Nano Banana 2 Lite (gemini-3.1-flash-lite-image) for low-latency, high-volume work. Grok Imagine Image 2.0 launched after the snapshot. Neither has a meaningful August cohort, so we do not pretend either has a comparable result here.
Those descriptions come from the providers, not from our benchmark. The corpus predates or spans several version changes — especially Midjourney versions — so the percentages below describe usage patterns, not the isolated capability of today's exact model build.
Google Nano Banana 2 and Pro: two lanes in one family
In the August snapshot, nearly half of the prompts attached to the banana-pro gallery cohort carry photographic technical language — a lens, an aperture, a film stock, a lighting setup. That is a far higher rate than the other two cohorts. It tells us people routed camera-shaped work to Nano Banana; it does not prove that both current Google models win every photography test.
Motion held against a still subject — a directorial instruction, not a style word.
Ultra-realistic cinematic street portrait of a young woman standing still in a crowded city street, sharp focus on her face with calm, intense expression. Long-exposure effect with people moving around her creating strong directional motion blur, streaked crowd movement while the subject remains perfectly still. Natural soft daylight, shallow depth of field, creamy bokeh, realistic skin texture, subtle freckles, neutral makeup, dark winter coat and scarf. Emotional, introspective mood, urban storytelling photography, DSLR quality, 85mm lens look, f/1.8, high dynamic range, 8K, professional color grading.
Google now separates that family into two main lanes. Nano Banana 2 is the speed and volume route; Nano Banana Pro is the studio route for complex layouts and higher-resolution work. Both support generation and editing, but their exact limits and prices differ.
Start here for: portraits and lifestyle photography, film-stock emulation, product shots that need to read as real, and reference-led work where details must survive edits. Browse the Nano Banana prompt library or use the character-consistency guide before committing a larger batch.
Access and cost: available through Google's Gemini surfaces and API. Free allowances, rate limits and per-image equivalents change; check Google's current pricing rather than a copied number here.
GPT Image 2: the layout model
The single sharpest number in the snapshot: over half of GPT Image prompts ask for text — headlines, captions, signage, typography — against 21.8% for Nano Banana and 7.9% for Midjourney. It is also the most illustration-leaning cohort at 36.2%.
That combination describes how people use it: as a design tool rather than a camera. It does not prove that every text-rendering task succeeds. OpenAI currently describes GPT Image 2 as a generation-and-editing model with flexible sizes and high-fidelity image inputs, so typography should still be tested with the exact words and layout you need.
Group composition with many faces to keep coherent — a layout problem before it's a lighting one.
Using REFERENCE_2 as the main character, outfit, and classroom-prop reference, regenerate the scene as a cleaner, finalized candid classroom photo with the same four women and the same edited coordinated outfits, but recompose them standing closer together behind the desks instead of sitting. Preserve the casual peace-sign energy and the Japanese school classroom setting, while changing the background to include a large dark chalkboard on the right and a doorway/cabinet area on the left. Make the camera angle slightly tilted, close, wide-angle, and flash-photo-like, with mild motion blur and realistic smartphone/disposable-camera texture. Keep the faces anonymized/blurred as in the references. Include exactly 4 women: left woman in a white open shirt over a cream top with a light denim mini skirt, second woman in a pink top with a cream pleated skirt and sweater tied at the waist, third woman in a dark blazer over a yellow top with a black mini skirt, and right woman in a blue shirt with a red tie and cream pleated skirt. Add a cluttered foreground desk with study and personal items, including a sticker-covered laptop, a silver laptop, magazines/books, a compact digital camera, a cream tote bag, small cosmetics/stationery, and a blue water bottle. Overall result should feel like the final polished generation after body-shape and outfit cleanup, keeping the playful group-photo mood from the references.
Start here for: posters and marketing assets, infographics, anything with legible words in the frame, illustration and character design. The GPT Image prompt library shows the full prompt beside each real output.
Access and cost: available through OpenAI's image APIs and ChatGPT image experiences. Plans and API prices change; use the current API documentation for the route you actually use.
Midjourney V8.2: the art-direction model
Midjourney's prompts are the least technical in the snapshot by both measures — 9.6% carry camera cues, 7.9% mention text. That is not a weakness; it describes a different working relationship. Users write shorter, more evocative prompts and let the model make more aesthetic decisions.
A world rather than a scene — the register Midjourney prompts tend to sit in.
Cinematic establishing shot, ultra wide angle, 2.35:1 anamorphic. An unimaginably colossal celestial whale, larger than mountain ranges, glides through an endless radiant cloud ocean. Its back is a thriving world: rolling hills, sacred forests, rivers, waterfalls, spirit trees, and lush gardens. Monumental East Asian imperial architecture grows organically from the terrain - endless palace complexes, towering pagodas, golden glazed roofs, crimson lacquered columns, jade terraces, hanging gardens. Thousands of suspension bridges, skywalks, and multi level streets form a vertical labyrinth. Crimson silk banners, glowing lanterns, bustling markets, robed figures, spirit beast caravans, and flying boats emphasize impossible scale. The whale has translucent jade skin, glowing ancient runes, bioluminescent veins, and crystalline fins. Its breaths lift the floating continent; massive fins push aside clouds, creating vortices. City occupies only a small portion of its back. Distant herds of equally colossal celestial whales drift beyond the horizon. Warm golden volumetric god rays, HDR, atmospheric scattering, PBR, ultra realistic cinematic fantasy, hyper detailed concept art, 8K, no text, no watermark. --chaos 80 --ar 9:16 --exp 100 --hd --profile novas9i --profile tgnnslq
Midjourney made V8.2 its default on July 24, 2026, and added a new Edit Model. The 4,305-item corpus row spans earlier versions, so it cannot tell you how much V8.2 alone changed prompt adherence or editing. For the practical differences, read Nano Banana vs Midjourney, then inspect the Midjourney prompt library.
Start here for: concept art, editorial illustration, world-building, and briefs where art direction is the main job. Midjourney sells subscription plans with GPU-time allowances; check its current plan page rather than treating that as a per-image price.
Stable Diffusion and the open-weight family
Different category, and worth separating clearly: Stable Diffusion, FLUX, Qwen-Image and Z-Image are models you can download and run yourself. That buys privacy, offline operation and freedom from a provider's per-image bill — at the price of setup, suitable hardware and your own operating costs.
If that trade is what you're weighing, we wrote it up in detail, including real VRAM requirements: Can you run Nano Banana locally?
Pick by task, not by score
| If you need… | Use | Why |
|---|---|---|
| A convincing photograph | Start with Nano Banana Pro or 2 | The August cohort has the highest concentration of camera-directed work; test the current route on your subject |
| Readable text in the image | Start with GPT Image 2 | 51.7% of its August prompts were text jobs; verify exact spelling before shipping |
| A striking, stylised image | Start with Midjourney V8.2 | Its cohort delegates more aesthetic decisions to the model |
| One character across many frames | Start with Nano Banana | Reference-led editing is the relevant workflow; test identity across the whole set |
| Posters, infographics, title cards | GPT Image 2 or Nano Banana Pro | Both are positioned for design work; run the actual copy and layout through each |
| Privacy, offline, or bulk at fixed cost | FLUX / Z-Image locally | No data leaves the machine, no per-image bill |
The honest summary: for most people the answer is not one model. The August gallery sample associates photographic briefs with Nano Banana, text and layout jobs with GPT Image, and open-ended art direction with Midjourney. Current versions can move those boundaries. Use the examples to choose what to test with your own brief; the sample does not establish which model will work best for you.
Grok Imagine Image 2.0 is deliberately absent from the recommendation rows: it launched after the fixed snapshot. Its official feature list puts it in the generation-and-editing shortlist, but we need a dated, matched test before assigning it a winning task.
Test it yourself
The fastest way to settle a comparison is to run the same brief through more than one model. The gallery examples below use different prompts, so they demonstrate range rather than a controlled result. Open any one to copy its full prompt, then run that unchanged brief across the models you are considering:
Judge each generator from a different prompt and whichever sample looks nicest
Run the identical subject, composition, text and reference-image task in every generator; compare instruction following before aesthetics
FAQ
Which AI image generator is best in 2026?
There isn't one, and any article that names a permanent winner is hiding the task and version. The fixed August snapshot shows three model families being used for measurably different jobs; the September model table names the current builds. Pick a model per task, then test that exact version.
How do Google's AI image generators compare with GPT Image 2 and Midjourney V8.2?
Google currently has two main lanes: Nano Banana 2 prioritises speed and volume, while Nano Banana Pro targets complex design and higher-resolution work. GPT Image 2 is also positioned for generation and editing, with flexible sizes and high-fidelity image inputs. Midjourney V8.2 remains a subscription-based art-direction workflow with its own prompt syntax and Edit Model. Those are product differences; the August percentages measure what users asked each family to do, not a head-to-head score.
Which one is best for realistic photos?
The Nano Banana cohort, by the clearest margin in our August usage data: 45.5% of its eligible prompts carry explicit camera direction, roughly 4.7× Midjourney's rate. That is a strong starting signal, not proof that every current Nano Banana build wins every photography prompt.
Which one renders text correctly?
Start with GPT Image 2, then verify the actual output. More than half of the eligible prompts in the 2,043-item GPT Image cohort are text jobs. That is a pattern in this curated sample, not proof of a general user preference or a guarantee of perfect spelling or layout on every generation.
Is Midjourney V8.2 still worth subscribing to?
If your work is stylised or conceptual, it can be. The corpus shows a workflow in which Midjourney users delegate more aesthetic decisions to the model. If your work is specification-heavy, compare one real brief against Nano Banana or GPT Image before committing to a plan.
