# Matrix-BIOS-Sentinel-0.1

**Developer:** Agent-Matrix · **Version:** 0.1 · **Task:** content-safety
classification · **License:** CC-BY-4.0

Sentinel is the **content-safety guardrail** of the **Matrix BIOS** family: a
small, fast, multilingual classifier that flags unsafe content (safe / unsafe) to
protect AI applications at scale. It is designed to run **on-premise** with low
latency and predictable cost.

## Model overview

- **Architecture:** multilingual encoder classifier
  (base: `distilbert-base-multilingual-cased`).
- **Output:** `safe` / `unsafe` with a calibrated risk score.
- **Optimised for:** real-time guardrailing of model inputs and outputs.

## Intended use

**Primary use cases**
- Content moderation and guardrails for chat, agents, and generation pipelines.
- A fast pre-screen that flags potentially harmful content for review or blocking.

**Out of scope (important)**
- Sentinel classifies **content safety** (harmful content), **not** operational or
  business risk. It will, by design, treat operational actions (e.g. deployments)
  as content-safe. **Operational and policy decisions are made by the governance
  layer, not by this classifier.**
- Decisions with legal or safety consequences require human review.

## How to use

```python
import torch
from transformers import AutoTokenizer, AutoModelForSequenceClassification

tok = AutoTokenizer.from_pretrained("ruslanmv/Matrix-BIOS-Sentinel-0.1")
model = AutoModelForSequenceClassification.from_pretrained("ruslanmv/Matrix-BIOS-Sentinel-0.1").eval()
p = torch.softmax(model(**tok("text to screen", return_tensors="pt")).logits, -1)[0]
print("P(unsafe):", float(p[1]))
```

## Governance & responsible use

Sentinel is **advisory**: it produces a recommendation, never a final authority. It
operates inside Matrix OS, where high-risk actions remain gated by policy and human
approval. It is a v0.1 release; evaluate on your own distribution before relying on
it for moderation decisions.
