# 🌤️ Weather Forecast — Powered by Open-Meteo & Mistral 7B

Ask anything in natural language and get a **7-day weather forecast** for every city you mention.

## How it works

```
User prompt  →  Mistral-7B (HF Inference API)  →  list of cities
    ↓
Open-Meteo Geocoding API  →  lat/lon for each city
    ↓
Open-Meteo Forecast API  →  7-day daily forecast
    ↓
Streamlit UI
```

## Stack

| Layer | Technology |
|-------|-----------|
| UI | Streamlit |
| Containerisation | Docker |
| LLM (NLP parsing) | Mistral-7B-Instruct-v0.3 via HF Inference API |
| Geocoding | Open-Meteo Geocoding API (free, no key) |
| Weather data | Open-Meteo Forecast API (free, no key) |

## Setup

files :

weather-app/
├── src
├──src
    └──streamlit_app.py
├── Dockerfile
├── requirements.txt
└── README.md
```

Open https://annanurov-rainytrek.hf.space/

## Example prompts

- *"What's the weather like in Paris and Tokyo?"*
- *"I'm travelling from Berlin to Rome next week, what should I pack?"*
- *"Compare weather in London, New York and Sydney"*

## Notes

- Open-Meteo is fully **open-source and free** — no API key required.
- The LLM call uses the **Hugging Face serverless Inference API** (`mistralai/Mistral-7B-Instruct-v0.3`). A free HF account token is sufficient for moderate usage.
- Temperatures are in **°C**, wind speed in **km/h**, precipitation in **mm**.
