# Responsible AI Bench

Independent evaluation dashboard for large language models and safety guardrails on localised content safety, RAG knowledge robustness, and demographic fairness, benchmarked for Singapore deployment contexts.

Built by the AI Testing & Evaluation team at GovTech Singapore.

## Benchmarks

| # | Benchmark | Metric | Direction |
|---|-----------|--------|-----------|
| 01 | Localised Undesired Content (RabakBench) | Refusal Rate | Higher is better |
| 02 | RAG Out-of-Knowledge-Base Robustness | Abstention Rate | Higher is better |
| 03 | Demographic Fairness | Disparity Score | Lower is better |

## Tech Stack

- Next.js 16 (App Router)
- React 19, TypeScript
- Inline styles + CSS variables (no CSS modules)
- Static data from CSV files in `public/`

## Getting Started

```bash
npm install
npm run dev
```

Open [http://localhost:3000](http://localhost:3000).

    parseGuardrails.ts # Guardrail CSV parsing + thresholds
    types.ts          # Shared TypeScript interfaces
    utils.ts          # Formatting + colour helpers

  models_data.csv       # Model evaluation results
  guardrails_data.csv   # Guardrail evaluation results
```

## Data

Evaluation results live in `public/*.csv`. To update scores, replace the CSV files and redeploy. The dashboard computes tercile thresholds at build time from the data.

## Deployment

```bash
npm run build
npm start
```

Compatible with any Node.js hosting (Vercel, Cloud Run, etc).
