Jun 25, 2025

Overview

The video reviews and demonstrates the capabilities of the Flux 1.1 Pro AI image generation model, focusing on how to achieve highly realistic, natural-looking images using specific prompt techniques.

Flux 1.1 Pro Model Highlights

  • All showcased images are AI-generated using Flux 1.1.
  • Flux 1.1 Pro offers six times faster generation than Flux 1 Pro.
  • Benchmarks position Flux 1.1 Pro as a leading image generation model.
  • Key providers include together.ai, segminds, rubberband.com, fal.ai, and free.aai, each with different access models and credit offerings.

Accessing Flux 1.1 Pro

  • together.ai grants $5 free credits on signup.
  • segminds provides 25 cents daily credits with the free plan.
  • rubberband.com allows 10 images per day for free.
  • fal.ai and free.aai require premium memberships for access.

User Interface and Parameters

  • together.ai interface offers minimal, straightforward parameters such as height, width, steps, and seed.
  • Users can input simple prompts to start generating images quickly.

Prompt Techniques for Realism

  • Using prompts in the format "image_####.cr2" (with any four random digits) mimics Canon camera file formats and yields highly realistic, natural images.
  • Limiting prompts to one or two words (e.g., "woman," "selfie") achieves more authentic results with imperfections.
  • Adding keywords like "cat" or "dog" generates highly believable animal photos.
  • Trying alternative file extensions (e.g., "heic," "jpeg") further diversifies the realism and randomness of outputs.

Limitations of Prompt Length

  • Longer, descriptive prompts lead to more traditionally “AI-looking” results with polished skin and blurred backgrounds.
  • Short prompts combined with file-type tricks yield better, less professional, but more natural images.

Realism and Imperfection

  • Flux 1.1 Pro excels at rendering realistic skin textures and natural-looking grain, shadows, and lighting.
  • Hands can sometimes appear less realistic, but faces and details are typically convincing.

Practical Demonstration Outcomes

  • Multiple prompt iterations demonstrate that Flux 1.1 Pro can create images indistinguishable from real photos when using the described techniques.
  • The method does not perform as well with detailed or lengthy prompts.

Recommendations / Advice

  • Use short, simple prompts combined with image file-type suffixes for best realism.
  • Avoid lengthy prompts if the goal is to achieve a natural, imperfect photo look.
