Troubleshooting

Quality Issues

Problem: Output looks blurry or low quality

Solutions:

1. Use higher quality model (Flux Kontext or Nano Ultra)
2. Check aspect ratio settings
3. Improve prompt specificity
4. Try higher resolution option

Inconsistent Results

Problem: Same prompt gives very different results

Solutions:

1. Use seed for reproducibility
2. Be more specific in prompt
3. Try Flux Kontext for consistency
4. Use reference images

Prompt Not Followed

Problem: Output doesn't match prompt

Solutions:

1. Simplify prompt
2. Use premium model for better adherence
3. Break into essential elements
4. Add emphasis to key elements
