Have you ever wondered how to tell if a text was written by a human or an AI? DeepMind and Hugging Face have teamed up to create a solution called SynthID Text. This tool adds a special tag, or watermark, to text generated by large language models (LLMs). Here's how it works:

Imagine you have a magic pen that adds a tiny, invisible mark to everything you write. That's what SynthID Text does for AI-generated text. It doesn't change how the AI works or the quality of the text. This magic trick was invented by researchers at DeepMind and shared in a paper published in Nature.

You don't need to retrain your AI to use SynthID Text. Just set some rules to balance the strength of the watermark and how well the AI responds. Each AI can have its own set of rules, stored safely to keep others from copying it.

For each set of rules, you need to train a special detector. It learns to spot the invisible mark in text. With just a few thousand examples of normal text and watermarked text, the detector gets smart.

DeepMind and Hugging Face open-sourced SynthID Text, making it easy for others to use. They tested it with Gemini models, showing it works well even with millions of users.

But remember, this tool isn't foolproof. It can't stop really sneaky people from causing harm. It just makes it harder for them. Combining it with other tools can help even more.
