A reference Python implementation of Google DeepMind's SynthID Text watermarking and detection technology for identifying AI-generated text. It extends Hugging Face Transformers models like Gemma and GPT-2 with watermarking mixins and provides both weighted mean and Bayesian detectors.

Use cases

• watermark text generated by LLMs like Gemma or GPT-2
• detect whether text was generated by an AI model
• reproduce results from the SynthID Text research paper
• experiment with LLM watermarking techniques in PyTorch
• train a Bayesian detector for watermark detection
• integrate watermarking into Hugging Face Transformers pipelines

When to choose

• you need a reference implementation for research or reproducibility of the SynthID Text paper
• you want to experiment with watermarking and detection on Gemma or GPT-2 models
• you are exploring AI-generated text detection techniques in Python

When to avoid

• you need a production-ready watermarking solution (use the official SynthID Text implementation in Hugging Face Transformers instead)
• you require cryptographic security guarantees for the hashing functions used
• you are not working with PyTorch or Hugging Face Transformers
