## Intended Use
|
| 51 |
+
|
| 52 |
+
This model is intended for text classification tasks with 5 output classes. It should not be used for generating text or for tasks outside its training distribution.
|
| 53 |
+
|
| 54 |
+
## Limitations
|
| 55 |
+
|
| 56 |
+
The model's performance is benchmark-specific and may not generalize to out-of-distribution inputs or domains not seen during training.
