It’s Monday morning. Your campaign goes live on Friday. You need 40 ad images, half of them with headlines built in, and every single one has to look like your brand.
You open three tabs: GPT Image 2, Midjourney and FLUX. And then you freeze. Which one do you actually use?
If that sounds familiar, you’re not alone. Two years ago, AI image tools were a novelty. Today, they’re table stakes. Your audience has stopped asking whether an image is AI and started asking whether it’s good. That shift changes the question you should be asking too. It’s no longer about which tool is the most impressive. It’s about which tool reliably gets great creative out the door.
This guide answers that. By the end, you’ll know exactly which tool to use for which job, and when juggling all three stops making sense.
The Quick Answer
Short on time? Here’s your cheat sheet. The rest of this guide explains why.
Selling a product? Use GPT Image 2.
Building a mood or a brand look? Use Midjourney.
Producing hundreds of images with a technical team? Use FLUX.
Now let’s meet the contenders.
Contender 1: GPT Image 2, the Conversion Closer
GPT Image 2 is OpenAI’s newest image model, released in April 2026 as the successor to GPT Image 1.5. Think of it as the tool that does exactly what you ask.
Where it shines
Its biggest strength is prompt accuracy. Ask for a woman in her mid thirties wearing business casual, holding a coffee mug, with soft morning light coming from the left, and that’s exactly what you get. No creative detours.
It’s also excellent at photorealism, which matters in paid ads where skeptical audiences scroll fast. People trust what looks real.
Its real party trick is text. GPT Image 2 renders words inside images far better than earlier OpenAI models, from signs and labels to full headlines. For marketers, that means your product name and call to action can live inside the image itself, saving you a round of design work.
Where it falls short
Its outputs can lean generic. Ask for a beautiful kitchen five times and you may get five versions of the same look. If you want a strong visual mood, such as cinematic, retro or documentary, expect to spend a few more prompts experimenting.
Hire it for
Product launches, lifestyle ads, ecommerce creative and any ad where the copy sits inside the image.

Pricing
You pay per image, and the cost depends on quality and size. There’s no subscription. Check OpenAI’s pricing page for current rates before you budget for a large campaign.
Contender 2: Midjourney, the Mood Maker
If GPT Image 2 is the dependable closer, Midjourney is the art director. Its images have a signature, crafted quality that feels intentional.
Where it shines
Style consistency is what sets it apart. Give it a direction like cinematic, Kodachrome film and warm colour grading, and every image that follows builds on that mood. For campaigns that need to feel cohesive across dozens of assets, that’s gold.
The public gallery is a bonus. It shows trending styles and successful prompts, so new users learn faster by seeing what works.
It’s also easier to start with than it used to be. Midjourney now runs in a web app, so you no longer need Discord to create images.
Where it falls short
Text is still hit or miss, so plan to add your headlines afterwards. It also reads prompts more loosely. Ask for a specific detail and it may focus on something else. Some teams love that creative freedom. Others find it frustrating on a deadline.
Hire it for
Brand awareness campaigns, mood boards, fashion, beauty, luxury and aesthetic first social content on Instagram, Pinterest and TikTok.

A serene interior, soft natural light, Scandinavian minimalism, muted palette, wooden furniture, editorial photography, shot on 35mm film.
Pricing
Midjourney runs on monthly subscription tiers based on how much generation time you need. If you create images every month, it usually works out cheaper than paying per image. If you only use it now and then, it’s a fixed cost either way.
Contender 3: FLUX, the Engineer’s Engine
FLUX is the choice for teams who want control under the hood.
Where it shines
FLUX comes in several versions, from faster, lighter models for testing to higher quality ones for final output. That lets you draft cheaply and spend more only on the images that matter.
Its biggest advantage is customization. Technical teams can train models on their own reference images and build versions made for a specific campaign, keeping every output consistent even at scale. For specialised visuals like technical products or industry imagery, that flexibility is hard to beat.
Where it falls short
It’s built for developers. You’ll usually work through an API or a platform built on top of it, and the documentation speaks to engineers more than marketers. Its community is also smaller than Midjourney’s, so you’ll build your own style library instead of borrowing one.
Hire it for
Large production volumes, agencies managing multiple clients and brands with technical people in house.
Pricing
You pay based on usage, and the lighter versions cost less. If you run it on your own setup, remember to budget for maintenance and monitoring too.

Find Your Match in 4 Questions
- What is the ad trying to do?
Drive a sale? Choose GPT Image 2. Build brand feeling? Choose Midjourney. Feed a large production pipeline? Choose FLUX. - Does the text need to be inside the image?
If yes, start with GPT Image 2. If your copy lives in the caption, Midjourney and FLUX are both good options. - How technical is your team?
Marketers without a technical background will be comfortable with GPT Image 2 or Midjourney. If you have engineers, FLUX gives you far more control. Mixed team? GPT Image 2 is the easiest place to start. - How many images do you need each month?
Just a handful? GPT Image 2 keeps costs predictable. A steady few dozen? Midjourney’s subscription starts to pay off. Hundreds? FLUX begins to make real financial sense.
Five Teams, Five Right Answers
The ecommerce launch
You need 80 product and lifestyle images with copy, due in two weeks. Use GPT Image 2 for the core product shots with headlines built in, and send the repetitive background shots to FLUX to keep costs down.
The B2B LinkedIn campaign
Your audience is professional, skeptical and needs to trust what it sees. Stick with GPT Image 2. Build 10 to 15 core scenarios, create a few variations of each and test them against each other to find your winners.
The DTC brand on TikTok
You need more than 200 images a month, and vibe matters more than polish. Lead with Midjourney to lock in a consistent look, and bring in GPT Image 2 only for close product shots.
The agency with five clients
Every client has a different brief, budget and aesthetic. Keep all three tools and match each job to what the client needs most: realism, mood or volume. Then track cost and performance for each tool.
The bootstrapped founder
Your budget is tight and your needs are varied. Start with GPT Image 2 for your core product shots, then add a Midjourney subscription once you’ve found a winning look worth exploring.
The Catch Nobody Mentions
Notice a pattern? The best performing teams rarely use just one tool. They mix them: product shots in one place, mood boards in another and volume work somewhere else.
But mixing tools creates its own problem. Three accounts. Three workflows. Three places where your brand guidelines can slowly drift. Before long, your marketers spend more time learning tools than actually marketing.
That’s the gap Mavic is built to close. Instead of deciding which tool fits each job, you simply tell Mavic what you need, such as 20 lifestyle variations of your hero product with campaign copy included. It handles the approach while keeping your colours, fonts and visual language consistent across every image. One workspace, one brand and no switching between tabs.
The Bottom Line
There’s no single best AI image tool. There’s only the best tool for the job in front of you.
GPT Image 2 closes sales. Midjourney builds moods. FLUX scales production.
Know which job you’re hiring for, and you’ll stop second guessing and start shipping better creative, faster.
