# Comparisons

## Comparisons among different model versions

Note that V1.3 is not always better than V1.2. You may need to try different models based on your purpose and inputs.

| Version | Strengths  | Weaknesses |
| :---: | :---:        |     :---:      |
|V1.3 |  ✓ natural outputs<br> ✓better results on very low-quality inputs <br> ✓ work on relatively high-quality inputs <br>✓ can have repeated (twice) restorations | ✗ not very sharp <br> ✗ have a slight change on identity |
|V1.2 |  ✓ sharper output <br> ✓ with beauty makeup | ✗ some outputs are unnatural|

For the following images, you may need to **zoom in** for comparing details, or **click the image** to see in the full size.
