Sentient Foundation releases a leaderboard for testing AI model fingerprints

A post says Sentient Foundation released its free, open-source Fingerprinting Leaderboard and the mlprints test code. Researchers submit ways to hide ownership marks in AI models; Sentient embeds them in test models, tries to strip them out and ranks how reliably they can be verified, how well they resist removal and their impact on model skill. The post says Sentient’s Perinucleus method embedded 24,576 fingerprints in Llama-3.1-8B without degrading utility; they survived standard fine-tuning.
