        This is a DistilBERT model fine-tuned on the Stanford Sentiment Treebank v2 (SST-2) dataset.
        
        - **Accuracy**: ~91% on the SST-2 validation set
        - **Size**: 66M parameters (compared to BERT's 110M)
        - **Speed**: ~60% faster than BERT
        
        The model classifies text as either positive (LABEL_1) or negative (LABEL_0).
