Comparison of Flux and Mid Journey AI Art Generators

Introduction

• Flux is a new open-source AI art generator.
• Some consider it a competitor to Mid Journey, dubbed the "Mid Journey killer."
• The presentation includes a comparison of both tools through various challenges.

Overview of Platforms

Flux

• Developed by the team behind Stability AI.
• Three models:
  • Schnell: Fast model for local development (easy to run).
  • Dev: Open-weight guidance model for non-commercial use.
  • Pro: State-of-the-art performance (best for creative capabilities).
• Claims to excel in:
  • Prompt following
  • Size and aspect variability
  • Typography accuracy
  • Output diversity
  • Visual quality

Mid Journey

• Recently updated to version 6.1.
• Focuses on coherent image generation, especially with complex features (e.g., hands).
• Improvements include:
  • Reduced pixel artifacts
  • Better text accuracy
  • Faster upscale process
  • Enhanced personalization and nuance.

Prompt Battle

Test Prompts

• Example prompts used for comparison across both platforms.
• Flux's model is run on Replicate.

Image Comparisons

1. First Prompt: Depth of field shot of a character.

   • Mid Journey: Captured emotion with a seductive pose.
   • Flux: Gave a darker, more morbid interpretation.
   • Mid Journey's aesthetics were preferred.

2. Hand Renderings:

   • Mid Journey: Good rendering of hands, but one image had excess fingers.
   • Flux: Initial outputs were poor, but a later attempt showed improvement, though still less appealing.

3. Complex Relational Prompt: Three wizards with signs.

   • Mid Journey: Struggled to adhere to the prompt.
   • Flux: Accurately depicted the scene on the first try.

4. Character Study:

   • Mid Journey: Better color range and aesthetics.
   • Flux: Inaccurate renderings (e.g., four fingers).

5. Architectural Prompt: Futuristic skyscraper.

   • Mid Journey: Superior detail and composition.
   • Flux: Poorly composed and less detailed.

Censorship and Content Restrictions

• Mid Journey: Strict censorship on gore and nudity.
• Flux: Open-source and uncensored, allowing more creative freedom.

Pricing

• Mid Journey:
  • Basic plan: $10/month for 200 images.
  • $30/month for unlimited images.
• Flux: Free if run on a powerful local machine; costs about $1 per 333 images when run on Replicate.

Training Data Concerns

• Mid Journey faced scrutiny over potentially using unauthorized data.
• Flux training data is less clear, but operates under open-source principles.

Conclusion

• Flux: Great for open-source enthusiasts; excels in relational prompts and is uncensored.
• Mid Journey: More aesthetically pleasing images overall, but has limitations on prompting complexity and is more expensive.
• Other noteworthy AI art generators include:
  • Idiogram: Excellent for text rendering.
  • Leonardo: Hybrid model with a balance of simplicity and complexity.
  • Rendered: Best for character consistency.
