There is nothing "Fun Sized" about the smaller Milk Duds box. A true horror story, that is.

Today, we've finalized this first phase of migrating the Hub to a new, modern storage system. One that's built to scale with AI builders of today and tomorrow. huggingface.co/blog/from-fi...

There's still a lot of work to do, but we're excited for what's next. 💪

This also serves as a reminder to myself that I owe a round of "Thank you"s to all the talented designers I've worked with over the years.

A sneaky part of making this all work is our backward compatibility with Git LFS. This allows us to roll out a significant protocol change without forcing workflow changes

We call this the Git LFS Bridge internally, and like our migration process, it's power is in its simplicity.

You can see over the past few months some of the biggest migrations show up in our cluster throughput.

Each spike corresponds to a significant migration (where we download from LFS and upload to Xet) with the baseline steadily increasing to just shy of 100 Gb/s

The engine behind moving from Git LFS to Xet is our migration process. It's simple, powerful, and has moved well over a dozen PB just by itself. Here's a high level view of how it works.
