| # FLUX.2 autoencoder, single file (mirror) |
|
|
| The single-file FLUX.2 VAE that |
| [stable-diffusion.cpp](https://github.com/leejet/stable-diffusion.cpp) needs for both FLUX.2 [dev] |
| and FLUX.2 klein, mirrored from |
| [Comfy-Org/flux2-dev](https://huggingface.co/Comfy-Org/flux2-dev). |
|
|
| Unsloth Studio fetches this on the no-GPU (native sd.cpp) path. It used to come straight from the |
| community repack; a rename or a takedown there turns every CPU FLUX.2 load into a 404, so it is |
| mirrored here. **The weights are unmodified:** byte for byte the file of the same name in the |
| source repo. |

| | `split_files/vae/flux2-vae.safetensors` | 0.31 GiB | [black-forest-labs/FLUX.2-dev](https://huggingface.co/black-forest-labs/FLUX.2-dev) (autoencoder) | Apache-2.0 | |
|
|
| ## Licence: Apache-2.0, and that is deliberate |
|
|
| The rest of FLUX.2 [dev] is under the FLUX Non-Commercial License. The **autoencoder is not**. |
| Black Forest Labs released it separately and says so in their own repository: "The autoencoder is |
| released under Apache 2.0" ([github.com/black-forest-labs/flux2](https://github.com/black-forest-labs/flux2)). |
|
|
| That matters here because FLUX.2 klein 4B is itself Apache-2.0 and needs this VAE. Bundling it |
| with the non-commercial conditioner would have put a permissive file behind a non-commercial |
| label. So it lives on its own, and the non-commercial half is at |
| [unsloth/FLUX.2-dev-ComfyUI](https://huggingface.co/unsloth/FLUX.2-dev-ComfyUI). |
