Running Krea 2 Turbo Locally on Mac
DaLyon92x · reddit · 2026-07-16
The author shares a complete guide to running Krea 2 Turbo locally on Apple Silicon and has open-sourced a ready-to-use ComfyUI workflow on GitHub.
Key points from the summary:
- The workflow is a single-file setup using only core nodes, ready to run after downloading the model.
- The author specifically troubleshoots common "silent failures" on Mac, such as black screens, static noise, or discolored outputs without error warnings.
- The recommended configuration is bf16 with a 26GB UNet, though 48GB of unified memory provides a smoother experience.
- For generation parameters, the author recommends 26 steps, cfg 1.0, euler/simple, noting that 8 steps appear too soft, while 20–26 steps is the sweet spot.
- It also lists several MPS pitfalls: batchsize can silently fail, setting LoRA strength to 0 can still cause black images, and cold starts take about 5 minutes.
Practical tips at the end: with cfg 1, results are primarily driven by positive prompts, so prioritize clear descriptions of photographic styles, skin details, and subject characteristics.
