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. 💪

The Hub is on 100% on Xet. 🚀 A little over a year ago, @hf.co acquired XetHub to unlock the next phase of growth in models and datasets. huggingface.co/blog/xethub-... In April, there were 1,000 Hugging Face repos on Xet. Now every repo (over 6M) on the Hub is on Xet.

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.

jsulz @jsulz.com · 15/07/2025
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.

What happens when you give an LLM a high-level objective to manage a small business and an incomplete toolset to achieve its aims? It makes questionable inventory and sales decisions, loses most of its money, and has an identity crisis. Not *so* far off from how I would perform.

These are hard numbers to put into context, but let's try. The latest run of Common Crawl was 471 TB. We now have ~32 crawls stored in Xet. At peak upload speed we could move the latest crawl into Xet in about two hours. 🤯🤯🤯

Meanwhile, our migrations have pushed throughput to numbers that are bonkers. In June, we hit upload speeds of 577Gb/s (crossing 500Gb/s for the first time).

It's been a bit since I took a step back and looked at our progress to migrate @hf.co from Git LFS to Xet, but every time I do it's mind boggling. A month ago there were 5,500 users/orgs on Xet with 150K repos and 4PB. Today? 🤗 700,000 users/orgs 📈 350,000 repos 🚀 15PB
