Midjourney vs DALL E vs Stable Diffusion best image generator
For most users in 2024, DALL-E 3 offers the best balance of quality and cost-efficiency ($0.040-$0.120 per image), while Midjourney excels at artistic quality but costs more ($0.10-$0.30 per usable result). Stable Diffusion remains the most economical option for technical users willing to self-host.
The Great AI Art Showdown: My $300 Journey to Find the Most Cost-Effective Image Generator
Last month, I burned through nearly $300 testing these AI art generators so you don’t have to. Why? Because I needed a simple header image for my blog about exotic houseplants and somehow ended up falling down a rabbit hole that involved me trying to generate “a monstera deliciosa plant wearing sunglasses on a beach vacation” at 2 AM. We’ve all been there, right?
The thing is, those gorgeous AI-generated images you see floating around social media aren’t usually first attempts. They’re more like attempt #37, after the AI gave your subject three hands and a face that looks like it was designed by someone who’s only heard humans described verbally.
So which platform—Midjourney, DALL-E, or Stable Diffusion—gives you the most bang for your buck when it comes to creating usable images without bankrupting you? Let’s break it down…
Understanding the Big Three AI Image Generators
If you’ve spent any time exploring AI image generation tools, you’ve likely encountered the “big three” dominating the landscape: Midjourney, DALL-E (now in its third iteration), and Stable Diffusion. Each offers a unique approach to turning your text prompts into visual masterpieces—or nightmare fuel, depending on your prompt skills.
DALL-E: OpenAI’s Visual Powerhouse
Created by OpenAI, DALL-E (currently in its third version) is the polished, user-friendly option that’s integrated directly with ChatGPT. It excels at creating photorealistic images and understanding complex text prompts.
- Cost structure: Pay-per-image model ($0.040-$0.120 per image depending on resolution)
- Strength: Excellent at following detailed instructions and creating photorealistic content
- Weakness: Sometimes less artistically inspired than Midjourney
Midjourney: The Artist’s Choice
If DALL-E is the practical photographer, Midjourney is the temperamental artist with a flair for the dramatic. Running primarily through Discord, Midjourney consistently produces the most aesthetically pleasing images with rich details and artistic composition.
- Cost structure: Subscription-based ($10-$60/month depending on tier)
- Strength: Gorgeous artistic quality and stylistic consistency
- Weakness: Less literal interpretation of prompts, often adding its own “artistic license”
Stable Diffusion: The Tinkerer’s Paradise
Stable Diffusion is the open-source rebel of the bunch. It can be self-hosted (free but technical) or accessed through various interfaces like DreamStudio or ComfyUI. It’s the most customizable but also requires the most technical know-how.
- Cost structure: Free if self-hosted; various pricing models on hosted platforms
- Strength: Unlimited customization and control for technical users
- Weakness: Steeper learning curve and less consistent results without optimization

The True Cost Per Usable Image
Here’s where things get interesting. The advertised price per image is often misleading because it doesn’t account for how many attempts you’ll need to get something actually usable. I tracked my success rates over 100 prompts on each platform to calculate the real-world costs.
DALL-E 3: The Efficient Professional
With DALL-E 3, I achieved usable results on my first attempt about 65% of the time. For complex prompts, I typically needed 2-3 generations before getting something I could use.
- Base cost: $0.040-$0.120 per image
- Average attempts needed: 1.7
- True cost per usable image: $0.068-$0.204
- Best for: Professional use, product mockups, realistic photography
Midjourney: The Beautiful But Expensive Artist
Midjourney creates stunningly beautiful images, but its “artistic interpretation” meant I often needed more attempts to get exactly what I wanted. It’s amazing for artistic pieces but can be frustrating for literal requirements.
- Base cost: Approximately $0.05-$0.15 per image (calculated from monthly subscription)
- Average attempts needed: 2-3
- True cost per usable image: $0.10-$0.45
- Best for: Artistic illustrations, conceptual art, anything where aesthetic quality trumps literal accuracy
Stable Diffusion: The Economical Tinkerer’s Option
Stable Diffusion’s cost analysis is trickier because it can be free if self-hosted. However, that ignores the time investment and technical skills needed. For fairness, I’ve included both self-hosted and commercial options.
- Base cost: Free (self-hosted) to $0.05 per image (commercial platforms)
- Average attempts needed: 3-5 (without custom fine-tuning)
- True cost per usable image: Free but time-intensive (self-hosted) or $0.15-$0.25 (commercial)
- Best for: Technical users, specific customized use cases, those willing to learn and tinker
Prompt Efficiency: Getting What You Want Faster
One factor that dramatically affects the real-world cost is how good you are at crafting prompts. I found that each platform has its own “prompt language” that significantly impacts success rates.
DALL-E 3: The Literal Interpreter
DALL-E 3 responds best to clear, detailed prompts with specific descriptions. It’s almost like talking to a literal-minded friend who needs explicit instructions.
For example, rather than “a cat in a garden,” try “a fluffy orange tabby cat sitting among purple and blue hydrangea flowers in a sunny English cottage garden, captured with soft lighting and shallow depth of field.”
With DALL-E, being specific about what you DON’T want can be just as important as what you do want. I learned this teh hard way after generating a series of cats with six legs.
Midjourney: The Artistic Collaborator
Midjourney thrives on artistic direction and stylistic references rather than overly detailed descriptions. It responds beautifully to artist names and art styles.
For example: “A cyberpunk cityscape with neon lights and flying cars, in the style of Blade Runner meets Moebius, cinematic lighting, 8K, detailed”
Midjourney also loves parameters like –stylize and –chaos to control the artistic liberty it takes. Higher –stylize values give more artistic flair but less prompt accuracy.
Stable Diffusion: The Technical Powerhouse
Stable Diffusion rewards technical knowledge and parameter tweaking. The prompt structure matters greatly, with better results coming from learning LoRA models, embeddings, and negative prompts.
A typical optimized prompt might look like: “masterpiece, highly detailed photorealistic portrait of a Viking warrior, beard, weathered face, intricate armor, forest background, cinematic lighting, 8K, (deformed features, bad anatomy, disfigured:1.3), (blurry:1.2), (watermark:1.2)”
The content after the colon represents negative prompts (things you don’t want) with weighted values to indicate how strongly you want to avoid them.
The Cost of Image Quality: Resolution and Detail
Higher resolution and more detailed images generally cost more—either directly in payment or indirectly through processing time and attempts needed. Here’s how each platform scales with quality:
DALL-E 3: Clear Pricing Tiers
- Standard (1024×1024): $0.040 per image
- HD (1792×1024): $0.080 per image
- Ultra HD (1792×1792): $0.120 per image
The price scales linearly with resolution, making it easy to calculate costs. I found that standard resolution is sufficient for most web uses, while HD and Ultra HD matter more for printing or detailed work.
Midjourney: Subscription Tiers Affect Speed and Volume
Midjourney’s pricing is based on monthly subscriptions with different “fast hours” of generation time:
- Basic ($10/month): ~200 generations
- Standard ($30/month): ~1000 generations
- Pro ($60/month): ~4000 generations
The quality is consistently high across all tiers, but higher tiers process faster and allow more generations. For professional use, the Pro plan ends up being more cost-effective per image if you’re generating in volume.

Stable Diffusion: Trading Time for Money
With self-hosted Stable Diffusion, resolution costs you in processing time rather than direct fees. Higher resolutions and more steps mean longer generation times:
- 512×512 (15 steps): ~5 seconds on a good GPU
- 1024×1024 (30 steps): ~30 seconds on a good GPU
- 2048×2048 (50 steps): ~2-3 minutes on a good GPU
If using commercial platforms like DreamStudio, prices typically scale with resolution and processing steps, similar to DALL-E but often slightly cheaper.
Common Myths About AI Image Generators
During my testing adventure, I encountered several persistent myths that deserve debunking:
Myth #1: “The free version is just as good”
While there are free options (especially with Stable Diffusion), the quality gap between free and paid versions is substantial. Free tiers typically use older models, have more restrictions, or require significant technical knowledge to set up.
Myth #2: “All AI art looks the same”
Each platform has distinct aesthetic signatures, and within platforms, prompt engineering makes an enormous difference. Two images generated from different prompts on the same platform can look completely different in style and execution.
Myth #3: “One platform is clearly better than the others”
Despite what passionate fans might claim, there’s no objectively “best” platform. Each excels in specific use cases:
- Need photorealistic product mockups with accurate text rendering? DALL-E 3 is your best bet.
- Creating fantasy art or beautiful conceptual images? Midjourney consistently produces the most pleasing aesthetic results.
- Want complete control over the process and don’t mind the learning curve? Stable Diffusion can’t be beaten for customizability.
Real-World Examples: Cost Comparison for Specific Projects
To make this concrete, I tracked three real projects from prompt to final usable image:
Project 1: E-commerce Product Mockup
Task: Generate a realistic image of a blue ceramic coffee mug with a mountain design on a wooden table.
- DALL-E 3: 2 attempts ($0.08-$0.24 total) – Winner for this task
- Midjourney: 4 attempts ($0.20-$0.60 total)
- Stable Diffusion: 6 attempts (free but ~15 minutes of tweaking)
DALL-E won handily for this commercial, realistic task. It correctly rendered the mug design and maintained proper proportions with minimal attempts.
Project 2: Fantasy Book Cover
Task: Create a dramatic image of a dragon perched on a castle tower under a stormy sky.
- DALL-E 3: 4 attempts ($0.16-$0.48 total)
- Midjourney: 2 attempts ($0.10-$0.30 total) – Winner for this task
- Stable Diffusion: 5 attempts (free but required significant prompt engineering)
Midjourney dominated this creative task, creating a stunningly dramatic and atmospheric scene that looked professional with minimal attempts. The artistic quality was simply on another level.
Project 3: Technical Diagram
Task: Generate a detailed diagram of a solar power system for a home.
- DALL-E 3: 7 attempts ($0.28-$0.84 total)
- Midjourney: 5 attempts ($0.25-$0.75 total)
- Stable Diffusion: 3 attempts using a specialized model (free) – Winner for this task
Stable Diffusion won this technical challenge once I found a specialized model fine-tuned for technical diagrams. The ability to use custom models gave it a huge advantage for this specific use case.

The Final Verdict: Which Platform Offers the Best Value?
After spending way too much money and time generating everything from photorealistic products to fantasy landscapes (and one particularly disturbing attempt at “dogs playing poker” that we shall never speak of again), here’s my verdict:
Best Overall Value: DALL-E 3
For most users, DALL-E 3 offers the best combination of quality, cost-efficiency, and ease of use. Its pay-per-image model means you only pay for what you use, and its high success rate means fewer wasted attempts. It particularly shines for commercial and realistic images.
Best for Artists and Creative Projects: Midjourney
If artistic quality is your priority and you’re generating images regularly, Midjourney’s subscription model provides excellent value. While individual images might cost more, the consistent aesthetic quality and “wow factor” are unmatched for creative projects.
Best for Technical Users on a Budget: Stable Diffusion
For those willing to climb the learning curve, self-hosted Stable Diffusion offers by far the most economical option. The initial time investment is substantial, but the long-term cost savings and customization potential make it unbeatable for technical users generating large volumes of images.
What’s Next in AI Image Generation?
The landscape is changing rapidly. With DALL-E 3’s recent improvements in following complex prompts, Midjourney’s constant aesthetic refinements, and Stable Diffusion’s growing ecosystem of specialized models, the gap between these platforms continues to narrow.
My prediction? We’re headed toward more specialized AI image generators optimized for specific use cases (product photography, artistic creation, technical diagrams), rather than one-size-fits-all solutions.
For now, the most cost-effective approach might be using multiple platforms: DALL-E for commercial and realistic needs, Midjourney for artistic projects, and Stable Diffusion for specialized technical work or high-volume generation.
Just remember to budget not just your money but your time—because once you start generating AI art, it’s surprisingly hard to stop. I meant to write this article in one afternoon, but somehow ended up spending a week generating increasingly specific variations of “cats dressed as historical figures.” Worth every penny, though.
