Training provenance:

The source images were generated with FLUX 3 Klein through WanGP. Training used Krea 2 RAW weights reconstructed from an installed INT8 checkpoint; quantization loss remains. The trained LoRA is for the Krea 2 architecture.

Inference quality and compatibility with specific workflows have not yet been validated.
