Kaggle Hub

Gemma models are available on Kaggle Hub for various formats:

• Gemma 4

• Gemma 3

• Gemma 2

• Gemma 1

To manually download the model:

• Select one of the Flax model variations

• Click the “Download” button to download the model archive

• Extract the model files from the archive

The archive contains both the model weights and the tokenizer, like:

2b/              # Directory containing model weights
tokenizer.model  # Tokenizer

To programmatically download the model:

import kagglehub

kagglehub.login()

weights_dir = kagglehub.model_download(f'google/gemma-3/flax/gemma3-4b-it')
