# What does this PR do? It is important to verify large checkpoints downloaded via `llama model download` because subtle corruptions can easily happen with large file system writes. This PR adds a `verify-download` subcommand. Note that verification itself is a very time consuming process (and will take several **minutes** for the 405B model), hence this is a separate subcommand (and not part of the download which can already be time-consuming) and there are spinners and a bit of a "show" around it in the implementation. ## Test Plan <img width="1012" alt="image" src="https://github.com/user-attachments/assets/f82b0d42-2a15-4917-b85e-6d3cd7d31e55">
