+# Adaptive Classifier
+
+This model is an instance of an [adaptive-classifier](https://github.com/codelion/adaptive-classifier) that allows for continuous learning and dynamic class addition.
+
+You can install it with `pip install adaptive-classifier`.
+
+## Model Details
+
+- Base Model: answerdotai/ModernBERT-base
+- Number of Classes: 4
+- Total Examples: 320
+- Embedding Dimension: 768
+
+## Class Distribution
+
+```
+legitimate: 80 examples (25.0%)
+likely_fraud: 80 examples (25.0%)
+needs_investigation: 80 examples (25.0%)
+suspicious: 80 examples (25.0%)
+```
+
+## Usage
+
+```python
+from adaptive_classifier import AdaptiveClassifier
+
+# Load the model
+classifier = AdaptiveClassifier.from_pretrained("adaptive-classifier/model-name")
+
+# Make predictions
+text = "Your text here"
+predictions = classifier.predict(text)
+print(predictions)  # List of (label, confidence) tuples
+
+# Add new examples
+texts = ["Example 1", "Example 2"]
+labels = ["class1", "class2"]
+classifier.add_examples(texts, labels)
+```
+
+## Training Details
+
+- Training Steps: 10
+- Examples per Class: See distribution above
+- Prototype Memory: Active
+- Neural Adaptation: Active
+
+## Limitations
+
+This model:
+- Requires at least 3 examples per class
+- Has a maximum of 150 examples per class
+- Updates prototypes every 10 examples
