SynthID Text watermarking in Transformers v4.46.0 for AI-generated content detection

AI Impact Summary

SynthID Text adds a watermarking mechanism for AI-generated text that is embedded during generation via a g-function, configured per model with SynthIDTextWatermarkingConfig and detected by classifiers. In Transformers v4.46.0, generation calls can be watermarked by passing a watermarking_config, and detectors can be trained and shared via the HF Hub, enabling enterprise-wide content provenance checks. While the watermark is designed to be imperceptible to humans, its effectiveness relies on detector training quality and remains vulnerable to heavy paraphrasing or translation, so governance and maintenance are required.
