# Chronos 🕰️

A retrieval-augmented generation (RAG) bot that answers questions about 20th-century history.

## What It Knows

- World War I & II
- The Cold War
- Major inventions and technological breakthroughs
- Key political events and figures

## How It Works

Chronos searches a curated knowledge base of historical Wikipedia articles, then uses a language model to generate answers grounded in those sources. It prefers admitting ignorance over hallucinating.

## Usage

```python
from pipeline import Chronos
bot = Chronos("path/to/model")
print(bot.ask("What caused World War I?"))
```

The model requires a compatible LLM and tokenizer placed in the same directory.

## Built With

- FAISS for retrieval
- Sentence Transformers for embeddings
- Cross-encoder for answer re-ranking
