+
+## Model Description
+
+This is a LoRA (Low-Rank Adaptation) fine-tuned model based on **roberta-base** for Intent Classification - Classifies text into categories like business, technology, science, etc..
+
+This model is part of the [semantic-router](https://github.com/vllm-project/semantic-router) project and is optimized for use with the Candle framework in Rust.
+
+## Model Details
+
+- **Base Model**: roberta-base
+- **Task**: Intent Classification
+- **Framework**: Candle (Rust)
+- **Model Size**: ~476MB
+- **LoRA Rank**: N/A
+- **LoRA Alpha**: N/A
+- **Target Modules**: 
+
+## Usage
+
+### With semantic-router (Recommended)
+
+```python
+from semantic_router import SemanticRouter
+
+# The model will be automatically downloaded and used
+router = SemanticRouter()
+results = router.classify_batch(["Your text here"])
+```
+
+### With Candle (Rust)
+
+```rust
+use candle_core::{Device, Tensor};
+use candle_transformers::models::bert::BertModel;
+
+// Load the model using Candle
+let device = Device::Cpu;
+let model = BertModel::load(&device, &config, &weights)?;
+```
+
+## Training Details
+
+This model was fine-tuned using LoRA (Low-Rank Adaptation) technique:
+
+- **Rank**: 16
+- **Alpha**: 32 
+- **Dropout**: 0.1
+- **Target Modules**: 
+
+## Performance
+
+Intent Classification - Classifies text into categories like business, technology, science, etc.
+
+For detailed performance metrics, see the [training results](https://github.com/vllm-project/semantic-router/blob/main/training-result.md).
