Open-Source SynthID-Text-Detector: Reference Implementation for AI Text Watermarking
jedisct1 · x · 2026-08-11
A developer has released a reference implementation for SynthID-Text-Detector. Based on the SynthID paper published in Nature, the project provides capabilities for watermarking and detecting AI-generated text.
The implementation enables watermarking by extending the GemmaForCausalLM and GPT2LMHeadModel classes from Hugging Face Transformers. It supports two detection methods: a training-free Weighted Mean detector and a more powerful Bayesian detector that requires training.
