AI models are the backbone of creating using generative AI. With the right model, you can transform your ideas into powerful visuals. In this blog, we’ll break down the seven models on Fiddl.art and guide you through which one best fits your project goals

What is an AI Model?

Before diving into the specifics, let's define what an AI model is in the context of creative tools. Simply put, AI models are algorithms trained on large datasets to generate images based on input prompts. Each model has strengths in different areas, some excel at photorealism, while others thrive in stylized or abstract generation. Choosing the right one can dramatically affect your results.

The Seven AI Models on Fiddl.art

1. Ultra: High Detail, Realistic Images

Best For: Photorealism, highly detailed and complex scenes.

If you're aiming for realistic visuals, Ultra is your go-to model. It excels in photorealism, with a particular strength in capturing minute details like textures, lighting, and depth. It’s perfect for creating lifelike characters, scenes, and high-quality visuals that require accuracy.

Pro Tip: Use Ultra for detailed character designs, high-end product renders, or immersive scenes like landscapes or cityscapes.

2. SD3-LG: Artistic, Stylized Images

Best For: Illustrations, sketches, and stylized visuals.

If you're more into illustrations or stylized art, this model excels in generating vibrant, creative images. It’s great for concept art, sketches, and scenes that don’t require the heavy details Ultra provides but need to maintain an artistic flair.

Pro Tip: Use SD3-LG when you want to create artwork with a painterly or illustrated style. It's ideal for storyboards, concept art, or even album covers.

3. Core: Balanced Creativity and Realism

Best For: Brainstorming, general use, and well-rounded images.

Core offers a solid middle ground between realism and creativity. It’s a versatile model, good for a wide range of styles, and provides an ideal balance of speed and quality. If you’re not sure which model to use, Core can be a great all-around option.

Pro Tip: Use Core for general art creation, whether it’s early design work, mood boards, or concept visuals.

4. DALL-E-3: Surreal and Imaginative Art

Best For: Surreal, dreamlike, and abstract visuals.

DALL-E-3 is a powerhouse for generating whimsical, surreal art that challenges the boundaries of reality. It’s particularly strong in imaginative prompts that require creative interpretations or abstract compositions. This model is a great fit for dreamlike, conceptual imagery where fantasy and imagination take center stage.

Pro Tip: Use DALL-E-3 to create fantastical scenes, imaginative creatures, or abstract art that doesn’t need to adhere to real-world logic.

5. Flux-Pro-Ultra: Top-Tier Photorealism and Detail

Best For: Professional-level imagery, high-end visual work.

If you need the highest level of detail for professional projects, Flux-Pro-Ultra delivers stunning, hyper-realistic imagery. This model is ideal for highly technical projects or when you need top-tier, polished visuals, like for marketing materials or product photography.

Pro Tip: Use Flux-Pro-Ultra for product renders, architectural designs, or any visual work where photo-quality accuracy is required.

6. Flux-Pro: Advanced, Detailed Visuals

Best For: Detailed, realistic art with a touch of creativity.

Flux-Pro is a slightly lighter version of Flux-Pro-Ultra, designed for highly detailed visuals but with a bit more flexibility in creativity. It’s ideal for complex designs that need accuracy but don’t require the ultra-high detail of Flux-Pro-Ultra.

Pro Tip: Choose Flux-Pro for detailed illustrations, promotional visuals, or scenes requiring realism without extreme precision.

7. Flux-Dev: Sharp Realism, Quick Results

Best For: Quick, sharp realism with good text generation.

Flux-Dev is great for scenes that require photorealism but also need a fast turnaround. It provides sharp images and has a faster generation process compared to some of the other models. It's particularly useful when you need results quickly without sacrificing too much realism.

Pro Tip: Use Flux-Dev for quick product mockups, advertising visuals, or scenes where time is of the essence, and quality still matters.

How to Pick the Best AI Model (Based on Your Workflow)

Picking a model isn’t just about style, it’s about how you work, how fast you need results, and what kind of visuals you want to create.

Ask yourself these 3 questions

Do I need realism or creativity?

If you’re aiming for lifelike visuals,  like product renders or detailed portraits, try Ultra, Flux-Pro-Ultra, or Flux-Dev.
For something more artistic, surreal, or stylized, go with SD3-LG or DALL·E 3.

Am I in a rush or going for max quality?

Need fast results? Flux-Dev and Core offer speed without a huge tradeoff in quality.
Need the highest visual polish? Flux-Pro-Ultra delivers professional-grade output.

What kind of art am I making?

Character-focused? Use Ultra for realism or SD3-LG for stylization.
Surreal concepts or imaginative scenes? DALL·E 3 is made for that.
Experimenting or brainstorming? Core is a reliable all-rounder.

Try This Prompt Across 3 Models

Want to see how different models interpret the same idea?

Prompt:
“A serene, otherworldly scene set in a dreamy wildflower meadow at golden hour. Transparent humanoid figures, smooth and androgynous in form, stand silently among vibrant, blooming flowers. Their clear bodies reflect the warm, setting sun, refracting rays of orange, gold, and pink across their glass-like surfaces”

Here’s what you’ll get:
Ultra → photoreal light play, crisp detail, and cinematic depth
DALL·E 3 → surreal glow, dreamlike atmosphere, poetic abstraction
SD3-LG → soft, illustrated textures and rich color blending

Try it for yourself and compare the results. You'll instantly get a feel for how each model brings its own flavor.

Conclusion: Find the Model That’s Right for You

By understanding the strengths of each model, you can choose the one that best supports your artistic goals. Try experimenting with different options, explore what works for your specific use case, and refine your process as you go.
