make this have one tab where you can chat with llama3.2-vision and upload images. and make a other tab wehere you can chat with llama3.1 and that has a search web tool and also has a image generation tool that uploads the image.png (demo tool) to the chat.
here is some example code how certaint stuff wokrs:
