This model was released on 2016-07-01 and added to Hugging Face Transformers on 2025-09-12.
VaultGemma is a text-only decoder model derived from Gemma 2, notably it drops the norms after the Attention and MLP blocks, and uses full attention for all layers instead of alternating between full attention and local sliding attention. VaultGemma is available as a pretrained model with 1B parameters that uses a 1024 token sequence length.
VaultGemma was trained from scratch with sequence-level differential privacy (DP). Its training data includes the same mixture as the Gemma 2 models, consisting of a number of documents of varying lengths. Additionally, it is trained using DP stochastic gradient descent (DP-SGD) and provides a (ε ≤ 2.0, δ ≤ 1.1e-10)-sequence-level DP guarantee, where a sequence consists of 1024 consecutive tokens extracted from heterogeneous data sources. Specifically, the privacy unit of the guarantee is for the sequences after sampling and packing of the mixture.

The example below demonstrates how to chat with the model with [Pipeline], the [AutoModel] class, or from the
command line.
from transformers import pipeline
pipe = pipeline(
task="text-generation",
model="google/vaultgemma-1b",
device_map="auto",
)
text = "Tell me an unknown interesting biology fact about the brain."
outputs = pipe(text, max_new_tokens=32)
response = outputs[0]["generated_text"]
print(response)
# pip install accelerate
from transformers import AutoModelForCausalLM, AutoTokenizer
model_id = "google/vaultgemma-1b"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id, device_map="auto")
text = "Tell me an unknown interesting biology fact about the brain."
input_ids = tokenizer(text, return_tensors="pt").to(model.device)
outputs = model.generate(**input_ids, max_new_tokens=32)
print(tokenizer.decode(outputs[0]))
