This analysis dives into the LFS storage on the Hub, breaking down the data by repository type, file extension, and growth over time. The data is based on a snapshot of the Hub's LFS storage, starting in March 2022 and ending September 20th, 2024 (meaning the data is incomplete for September 2024). Right now, this is a one-time analysis, but as we do our work we hope to revisit and update the underlying data to provide more insights."

Well, the [Xet Team](https://huggingface.co/xet-team) is a [new addition to Hugging Face](https://huggingface.co/blog/xethub-joins-hf), bringing a new way to store massive datasets and models to enable ML teams to operate like software teams: Quickly and without friction. Because this story all starts with storage, that's where we've begun with our own deep dives into what the Hub holds. As part of this, we've included a look at what happens with just one simple deduplication strategy - deduplicating at the file level. Read on to see more!"

As part of the [Xet team](https://huggingface.co/xet-team), one of our goals is to improve Hub storage and transfer efficiency, and understanding how and what things are currently stored helps us establish a baseline. This analysis uses a snapshot of the Hub's Git LFS usage from March 2022 - September 2024, which accounts for 82% of all Hub storage, and we plan to update it monthly to track trends. We're starting with metrics around raw storage by repository type and size/count by file extension - if you're interested in other metrics, drop your suggestions in our [discussions](https://huggingface.co/spaces/xet-team/lfs-analysis/discussions)!"
