# Corrosion Assistant — Beta

**Welcome!** This demo runs a custom **ResNet50 corrosion classifier** and connects to a dedicated **PPG Assistant** on OpenAI.  
- **Model**: ResNet50 classifier, **trained locally** on ~**9,000 images**  
- **Data collection**: a public link for contributing images will open **soon**  
- **Disclaimer**: research & experimental only. No professional advice, no warranty.  

After image analysis you can continue chatting with the assistant.

## How it works
1. Upload or take a photo.
2. The model predicts the corrosion class.
3. The OpenAI Assistant replies with PPG-style technical advice.
4. Keep chatting with the assistant using the last classification and the selected zone.
