  - 5.6B model, released on October 16, 2026
  - Base model + Kijai's Step Distilled LoRA at 0.8 strength
  - Using er_sde + beta, 20 steps, CFG 1
  - Using Create Bounding Boxes node, prompt upsampler covers the entire reference image
- **Qwen Image 2.1 (QI2)**
  - 7B model, released on September 21, 2026
  - Base model + Turbo 8-step LoRA at 1.0 strength
  - Using er_sde + beta, 8 steps, CFG 1
  - Using Texture fix VAE

  - 9B model, released on January 16, 2026
  - Distilled model
  - Using er_sde + Flux2Scheduler, 4 steps, CFG 1

#### Task Descriptions
1. **Basic Edits**: Adding, removing, and modifying elements in the image.
   - Example: Remove the umbrella above the subject, add a tourist boat on the canal, change the astronaut suit color to orange.
2. **Character Sheet**: Maintaining identity consistency across different poses, angles, and a head close-up.
   - Example: Create a photorealistic live-action reference sheet on a neutral grey background, showing the same subject in three poses.
3. **Change Location**: Changing the background and lighting.
   - Example: Change the background to a dark spaceship interior, the only light sources are the neon lights on the wall.
4. **Pose Transfer**: Transferring the pose from one subject to another.
   - Example: Change the pose of the person from Picture 2 to match the pose in Picture 1.
5. **Head Swap**: Handling head swap while keeping the original body, pose, and expression.
   - Example: Replace the subject's head from Picture 1 with the subject's head from Picture 2.
6. **Style Transfer**: Transferring style from one image to another.
   - Example: Transfer art style from Picture 2 to Picture 1.

#### Conclusion
FLUX.3 Klein performs well in many editing tasks, especially in basic edits and change location tasks. Although it lags slightly behind in character sheet and pose transfer tasks, it is generally comparable to Qwen Image 2.1. FLUX.2 Klein 9B excels in some tasks but still has room for improvement in identity consistency and detail preservation.
