Model Watermarking
A technique for embedding covert markers into AI model weights or model outputs, used to trace model provenance and detect unauthorized copying or distillation. The approach is broadly divided into two categories: weight-level watermarking, which embeds markers directly in model parameters, and output-level watermarking, which encodes markers in the model's generated outputs.
Timeline (last 90 days)
Technical approaches to defending against distillation include perturbing outputs, limiting query frequency, or introducing watermarks.
Model watermarks fall into two categories: weight watermarks and output watermarks.
Model watermarking actively injects specific patterns into model outputs, whereas model fingerprinting extracts the model's inherent behavioral features that can be used for identification.
Some providers embed watermarks in outputs that do not affect semantics but can trace the source, enabling identification of the original source in the outputs of suspected distilled models and providing technical evidence for legal accountability.
