Choosing among the four major image models comes down to one sentence: pick Midjourney V7 for artistic, stylized creative work; Grok Imagine for fast, photorealistic images; GPT Image 2 for accurate in-image text and precise instruction following; and Nano Banana 2 for faithful product reproduction and localized edits. You don't need four separate signups — on Flux Art, a one-stop AI visual generation workspace that bundles 50+ top global image and video models under a single account, you get all four, with direct, stable access from China and no extra network setup, up to 4K output, no watermarks, and commercial-use rights. This article uses a "same brief, four models, four images each" comparison method to show exactly which model should take which task, with image selection and localized fixes wrapped up in the same workspace.
I've worked as an AI visual workflow consultant for three years, helping e-commerce and content teams turn image generation from "trial and error" into "tasks assigned by model strengths." Head-to-head comparison is my most-used method: same brief, same baseline prompt, every model generating side by side, then compared along fixed dimensions. There's no barrier to entry — after reading this, you can run a round yourself.
Why Is There No "All-Rounder" Among the Four Major Image Models?
Because the four models were built around different product philosophies. Midjourney V7 has always leaned toward artistic expression — composition, color, and atmosphere are its recognized strengths. Grok Imagine is xAI's image generation capability: quick to pick up, with distinctive realism and creative styles. GPT Image 2 is OpenAI's image model, strong at instruction understanding and text rendering, with 12 quality-and-resolution combinations up to 4K. Nano Banana 2 comes from the Google Gemini family, offering 14 aspect ratios and up to 4K, and excels at multi-image fusion and precise localized inpainting. Asking Midjourney to draw a banner with Chinese promo copy, or asking GPT Image 2 to produce extreme stylized illustration, means forcing a model's weak spot onto the task — and wasting your credits and time.
More people are generating images with AI than ever. According to CNNIC's 57th Statistical Report on China's Internet Development, generative AI users in China reached 602 million by December 2025, up 141.7% from December 2024. With a base that large, "knowing how to generate images with AI" is no longer a competitive edge — knowing which model fits which job is what sets you apart.
Now consider the hassle of the traditional route. To use all four models, the official path means registering four separate accounts; the native entry points for the Grok lineup and Midjourney require an overseas network environment and overseas account systems, which this article won't walk through. Four subscriptions bill separately, and you pay for the full month even when you can't use up a tier. Most people end up keeping just one provider and cramming every task into a single model — which makes comparison impossible, and division of labor along with it.

Which Job Belongs to Which Model? One Table Makes It Clear
Here's the conclusion table up front. It compares use-case fit, not scores — models aren't absolutely better or worse, only right or wrong for the job:
| Model | Made by | Strengths | Best-fit tasks | Tasks better handed elsewhere |
|---|---|---|---|---|
| Midjourney V7 | Midjourney | Artistic, stylized, atmospheric output | Mood boards, concept drafts, illustration-style hero images | In-image text, faithful product reproduction |
| Grok Imagine | xAI | Quick to pick up; distinctive realism and creative styles | Photo-real editorial shots, creative scene images | Jobs that must strictly lock reference-image details |
| GPT Image 2 | OpenAI | Instruction understanding, text rendering, multi-image fusion; 12 combinations up to 4K | Posters with text, banners, commercial images with clear specs | Extreme stylized artistic expression |
| Nano Banana 2 | Google Gemini family | Multi-image fusion, precise localized inpainting; 14 aspect ratios up to 4K | Product reproduction, localized edits, multi-reference composites | Open-ended creative exploration from scratch |
How to use this table: when a task lands, ask two questions — does the image contain elements that must be accurate (text, product, logo), and does it demand a strong style? If the first answer is "yes," lean toward GPT Image 2 and Nano Banana 2; if the second, lean toward Midjourney V7 and Grok Imagine.
One more note: "better handed elsewhere" doesn't mean "can't do it." Midjourney V7's in-image text errors, for instance, are a widely known issue — you can keep rerolling and hoping, but GPT Image 2 often nails the same task in one shot, and the credits you save cover several more finals.

Which Kind of Image Maker Are You? Match Your Role to a Plan
If you'd rather not memorize four models' quirks, matching by role is faster:
| Your scenario | Biggest pain point | How to do it on Flux Art | Recommended primary model / approach |
|---|---|---|---|
| E-commerce designer | The product can't be distorted, and the image needs promo text | Upload a white-background product photo as reference; generate scene and text as separate layers, then composite | Nano Banana 2 to lock the shape + GPT Image 2 for the text |
| Content creator / blogger | Hero images need a recognizable look — and you need one every day | Fix one set of style prompt templates, swap the subject per post, generate 4 and pick 1 | Midjourney V7 or Grok Imagine |
| Brand designer | Too many directions during pitching, urgent revision cycles | Explore directions with a stylized model, then switch to a realism model to converge after sign-off | Midjourney V7 to diverge + Grok Imagine to converge |
| Marketing planner (non-designer) | Can't write complex prompts | Adapt keywords in 20K+ prompt templates; instruction-style descriptions generate images directly | GPT Image 2 |
Once you've found your row, don't rush into bulk generation: take your most common task type and run a small comparison round following the next section. A division of labor validated on your own briefs is the only one that truly counts as yours.

How Does a Complete Four-Model Comparison Run?
- Set the brief and dimensions (about 10 minutes): pick a task from your real business, such as "a portable coffee maker in outdoor morning light." Fix four comparison dimensions — composition and mood, subject accuracy, usable text, and cost of revision. Record performance only; no scoring.
- Write the baseline prompt (about 10 minutes): one neutral sentence covering only subject, scene, and lighting, e.g. "a portable coffee maker on a camping table, low-angle morning sunlight, mountain meadow in the background." Leave style words out for now — test them separately.
- Generate 4 images per model (about 20 minutes): send the same prompt to all four models, uniform 1:1, 4 images per round; set GPT Image 2 and Nano Banana 2 to the 2K tier and leave Grok Imagine and Midjourney V7 on defaults; for product briefs, upload a white-background reference to Nano Banana 2.
- Record by dimension (about 15 minutes): put all 16 images side by side and mark each dimension as "usable as is / needs fixing / discard," noting each discard's failure type: garbled text, distorted subject, or flat mood — each is a different problem.
- Distill a task-to-model list (about 10 minutes): write the conclusions into a task-to-model reference list, marked with the comparison date. Next time a job comes in, skip the testing and assign straight from the table.

What If the Four Models' Outputs Can't Be Compared at All? A Real Failure, Fixed
Last month I ran this comparison for a client that makes portable coffee gear — the exact brief above. In the first round I cut corners and threw a single style-word-stuffed prompt at all four models as-is, 1:1, four images each. The results were impossible to compare: the Midjourney V7 set had the best mood, but the pot's shape was completely off and the English on the packaging came out garbled — in-image text errors are a publicly known issue for it; Grok Imagine looked real enough, but the pot looked different in every one of its four images; GPT Image 2 followed instructions best, but the morning light was as flat as an overcast day; Nano Banana 2 never got a reference image, so it guessed every product detail. The problem wasn't the models — it was me failing to control the variables. The fix took three steps. First, strip the style words out of the baseline prompt, keep only a neutral description of subject, scene, and lighting, and rerun all four. Second, upload the white-background product photo for Nano Banana 2 and regenerate at the 2K tier — the pot's shape locked in immediately. Third, add one extra line just for GPT Image 2 — "low-angle morning sunlight, backlit rim light" — and the mood came back. With the second round's 16 images side by side, the conclusion was obvious at a glance: Midjourney V7 sets the direction and mood, Nano Banana 2 produces the final product shots, GPT Image 2 delivers text-bearing promo images straight out, and high-volume lifestyle scenes go to Grok Imagine.
Check Before You Deliver: The Four-Model Comparison Checklist
- Unify the variables: same baseline prompt, same aspect ratio, same image count; test style words in a separate round.
- Complete the references: for product-reproduction briefs, Nano Banana 2 must get a white-background reference before you compare.
- Test text separately: give in-image text its own brief — don't mix it into mood briefs and draw the wrong conclusion.
- Keep records practical: only note "usable / needs fixing / discard" plus the failure type — no abstract scores.
- Turn conclusions into a table: the deliverable of a comparison is a "task-to-model" reference list, not a pile of images.
- Archive the samples: keep generation records and parameters so results can be reproduced and explained to the team.
- Date everything: models iterate fast — note the comparison date on the list, and rerun the same briefs the next season.
When Do You Not Need an Aggregator Platform?
If your tasks are simple and infrequent — a few images a month in a fixed style — one provider's subscription or a free tier is plenty; and if you already subscribe to one provider and your usage fits it well, there's no need to pay again just to "have it all." Comparison has its limits, too: it helps you choose a model, but it can't replace aesthetic judgment. One more thing worth spelling out: a so-called "China-side entry point for overseas models" essentially means an aggregator platform connecting the original models — Grok Imagine, Midjourney V7, GPT Image 2, Nano Banana 2 — for use in China. The model capabilities belong to their original makers; what the platform provides is stable access, a unified account, and credit-based billing. Understand your task mix first, then decide whether an aggregator platform is worth it.
