+## Model Limitations
+- *Human Assessment Required*: This model should not be used for automatic classification of grant peer review reports without human oversight.
+- *Limited Training Data*: The model was fine-tuned on a limited sample of 2,500 annotated sentences. Therefore, its classification accuracy should be critically evaluated before deployment.
+- *Specific Training Data*: The training data consists of a random sample of SNSF grant peer review reports. As such, the model's external validity to other datasets may be limited.
+
+### Disclaimer
+The classification accuracy of this model is notably low. Therefore, any deployment should be approached with caution and thorough consideration.
+
+Since *Rationale* was only considered for *Positive* or *Negative* statements in the annotation, the predictions of the `snsf-data/specter2-review-rationale` model should be adapted in conjunction with the prediction of the models `snsf-data/specter2-review-positive` and `snsf-data/specter2-review-negative` as follows:
+- if a sentence's prediction is either *Positive* or *Negative*, retain its *Rationale* prediction
+- if a sentence's prediction is neither *Positive* nor *Negative*, disregard its *Rationale* prediction.
