🚀 How It Works

1. User types a query into the input field.
2. JavaScript fetches the response via a PHP script (api.php) using the Groq API.
3. The backend uses the provided role and prompt to query the LLaMA 3 model.
4. The model's response is displayed dynamically in a chat bubble.

cd AI-Chabot

2. Configure the API Key

Edit api.php and replace the placeholder:

$secretKey = 'YOUR_GROQ_API_KEY_HERE';

🔐 Important: Never expose this key on the frontend or commit it to public repositories.

✅ Example Role & Prompt

The system instructs the model to act as:

Role: "You act as a Doctor named Yasir."
Prompt: "I have a headache and fever. What should I do?"

Expected response will be from Dr. Yasir, offering medical guidance powered by LLaMA 3.
