WhatsApp AI Assistant with LLaMA 4 and Google Search

This workflow creates a real-time AI chatbot on WhatsApp powered by Groq’s LLaMA 4 model with Google Search (SerpAPI) for fresh insights.

Who’s it for

• Users who want an AI assistant directly on WhatsApp.
• Businesses needing real-time FAQ and support automation.
• Anyone wanting a chatbot that remembers past messages and uses live search.

What it does

• Connects WhatsApp to Groq’s LLaMA 4 model for AI responses.
• Uses SerpAPI to fetch real-time search results from Google.
• Maintains context of the last 20 messages for continuous conversations.

How it works

1. A user sends a message to your WhatsApp number.
2. The workflow checks if it’s text (images can be added later).
3. Text is sent to the AI Agent, which uses Groq’s LLaMA 4 for responses.
4. If real-time info is needed, SerpAPI fetches results from Google.
5. The reply is composed and sent back to the user via WhatsApp.
