Google · 12 September 2025

VaultGemma is a 1B-parameter Gemma-based model trained from scratch with differential privacy. Weights and technical report were released with a scaling-law study for DP training.

Google Research derived scaling laws for compute, privacy budget and utility, then trained what it calls the largest open model trained from scratch with differential privacy. Google says utility is comparable to non-private models from roughly five years ago.
