Kaggle Notebooks
kaggle.com/code
Free cloud notebooks with 30 hours per week of GPU access (dual T4), internet connectivity during training, and direct access to thousands of public datasets — all without any payment setup.
Why it is useful
More generous than Colab's free tier in some ways — 30 GPU hours per week is a predictable and significant allocation, and the dual T4 setup enables larger batch sizes and faster training. Direct integration with Kaggle datasets means you can start training on competition data immediately. The persistent environment and version history make it more suitable for ongoing projects than Colab's ephemeral sessions.
