# 🛡️ Ordinal LLM — ordinal-2b

**2.2B Security-Specialized Language Model with Anti-Hallucination Architecture**

> ⚠️ This is the model architecture and configuration. Trained weights will be uploaded separately after training.

## Architecture

| Parameter | Value |
|-----------|-------|
| Parameters | ~2.2B |
| Hidden Size | 2560 |
| Layers | 28 |
| Attention Heads | 20 (GQA: 4 KV heads) |
| Head Dim | 128 |
| Intermediate | 6912 |
| Vocab Size | 50304 |
| Max Context | 8192 |
| Dtype | bfloat16 |

## Anti-Hallucination Features

1. **Confidence Head**: Per-token reliability score (threshold: 0.7)
2. **Retrieval-Augmented Attention**: 4 retrieval heads, dim=256
3. **Fact Verification Layers**: At layers [9, 18, 27]
4. **Source Grounding Embeddings**: 16 source types

## Usage

```python
from transformers import AutoModelForCausalLM, AutoConfig

# Load config
config = AutoConfig.from_pretrained("Haruster/ordinal-2b", trust_remote_code=True)

# Load model (after weights are uploaded)
model = AutoModelForCausalLM.from_pretrained("Haruster/ordinal-2b", trust_remote_code=True)
```
