Description

Full video: 🎥 https://youtu.be/UwX5zzjwb_g Large language models often memorize what they see — even a single phone number or address can stick forever in their weights. Google’s new VaultGemma changes that: it’s the first open-weight LLM trained from scratch with differential privacy, meaning secrets seen seldomly during training leaves no trace. 👉 In this video, we explain Differential Privacy through the concrete example of VaultGemma — how it works, why it matters, and what it means for the future of trustworthy AI.

What you'll learn

Differential privacy is a technique that allows large language models to be trained without sensitive training data becoming permanently stored in model weights
VaultGemma is the first open-weight LLM trained from scratch with differential privacy by Google Research
Differential privacy prevents rarely seen secrets from training data, such as phone numbers or addresses, from being permanently retained in the model

Frequently asked questions

What is the problem with standard large language models and training data?

Standard LLMs often permanently memorize training data, including sensitive information such as phone numbers or addresses that become embedded in model weights.

How does differential privacy solve this problem?

Differential privacy ensures that rarely occurring secrets from training data leave no permanent trace in the model, providing better protection for sensitive information.

What makes VaultGemma special?

VaultGemma is the first open-weight LLM trained from scratch entirely with differential privacy, making it an innovative example of trustworthy AI.
