## Architectural Guidelines

- Krea 2 DiT models utilize a single-stream architecture requiring 16-channel Wan2.1 VAE. Using standard Flux or SDXL VAE causes severe checkerboard distortion.
- Consumer GPU target: 12GB VRAM (RTX 4070). Workflows utilize GGUF / FP8 quantization and CPU offloading where needed to prevent CUDA out-of-memory errors.
