| ## 🏗️ Architecture | |
| ### Data Pipeline | |
| ``` | |
| Web Sources → Scraper → JSON Dataset → Chunker | |
| ↓ (7 sources) ↓ (1000+ docs) ↓ | |
| - SAP Community sap_dataset.json 512-token chunks | |
| - GitHub repos + metadata with overlap | |
| - Dev.to articles | |
| - Tech blogs | |
| ``` | |
| ### Processing Pipeline | |
| ``` | |
| User Query → FAISS Search → Top-K Chunks → LLM | |
| ↓ ↓ ↓ ↓ | |
| Chat Vector Index Context Response | |
| Input (similarity) Assembly + Sources | |
| ``` | |
| ### LLM Options Pipeline | |
| ``` | |
| User Settings → Provider Selection → Model Load → Generate | |
| ↓ ↓ ↓ ↓ | |
| Local/Cloud Ollama/Replicate/HF Model Answer | |
| Preference Free tier Inference Quality | |
| ``` | |
| ## 🔧 Customization Points | |
| ### Easy to Modify | |
| 1. **Data Sources** - Edit `build_dataset.py` to add sources | |
| 2. **Models** - Change in `config.py` | |
| 3. **Prompts** - Update in `config.py` | |
| 4. **UI Theme** - Modify CSS in `app.py` | |
| 5. **RAG Settings** - Adjust in `config.py` | |
| ### Advanced Customization | |
| 1. **Custom LLM Provider** - Add class to `agent.py` | |
| 2. **Different Embeddings** - Change in `embeddings.py` | |
| 3. **Custom Chunking** - Modify `RAGPipeline.create_chunks()` | |
| 4. **Custom UI** - Extend Streamlit components | |
