| # FLUX2-KLEIN-4B-BIREFNET-RUNTIME |
|
|
| Public deployment bundle for the GhostStack WF-02 isolation runtime. This |
| repository contains unchanged upstream model component files. GhostStack did |
| not train, merge, convert, quantize, fine-tune, or otherwise modify these |
| weights and does not claim ownership of them. Each component retains its |
| upstream license; see `LICENSE` and `NOTICE`. |
