Hugging Face reports 27.7 GB of storage for the whole repository. That figure can include several packs, so the fit table does not use it as the size of one file.
Will it fit?
Save a machine on the hardware page and this block fills in. The table already has the sizes.
| Pack | Size | Saved machine |
|---|---|---|
| Largest published checkpoint | 7.8 GB weights + 4.0 GB allowance. File: split_files/diffusion_models/flux-2-klein-4b.safetensors. | Choose a machine |
Estimate rows use the parameter count. A measured row names a file in the repository. The allowance is fixed: it stands in for context or activations, and it is not a measurement from a run.
How to run it
Image checkpoints are usually run in Diffusers or ComfyUI. The fit row adds a fixed activation allowance. It is not a picture this desk rendered.

This directory is assembled from public model records. Freshness is age. Popularity is downloads and likes. A fit figure is an estimate from a parameter count or from a published file size, not a run on our hardware. How the numbers are made. AI disclosure.
