 This project demonstrates an interactive audio and text chat interface powered by the Gemini AI model. Users can speak to the AI or type text to communicate with it.
 
-The AI is capable of calling external tools, searching for information on Google, and running code snippets. Function calling by the AI is performed on the server side, and results are sent back to the client. This approach is crucial for functions requiring access to server-side data or functionalities.
+The AI is capable of calling external tools, searching for information on Google, and running code snippets. Function calling by the AI is performed on the client side, and results are processed locally. This approach is crucial for functions requiring access to client-side data or functionalities.
 
-A separate Space will be created later for client-side function calling.
+For server-side function calling, visit: [Gemini Live Function Call](https://huggingface.co/spaces/Nirav121/gemini-live)
 
 The server uses Docker for deployment, making it easy to deploy on any platform that supports Docker.
