Six Krea2 workflows built around one idea — draft with RAW, finish with Turbo, and never let a single sampler do both jobs.
The core mechanism
RAW produces structure. Turbo produces finish. Running them as one pass forces a compromise; running
them as two passes lets each do what it is good at.
The six workflows are variations on that split:
| # | Workflow | Focus |
|---|---|---|
| 1 | Dual-phase finalize | The base two-pass chain |
| 2 | Merged model | A single merged checkpoint equivalent |
| 3 | 4K/6K upscale chain | Mega-resolution output |
| 4 | New sampler engine | Clownshark × WanVAE texture variant |
| 5 | Texture unlock core | Control-enhanced variant |
| 6 | RAW base + Turbo chain | Reference configuration |
The upscale chain
4K and 6K output from a two-pass chain is where the order of operations shows. Upscaling before the
Turbo pass preserves texture; upscaling after it produces a smooth, slightly plastic 6K image.
