Mecha, androids, cyborgs... and much more. The model requires a precise and specific prompt. The settings are standard; I generated the images using a LoRA strength of 1. While combining it with other LoRAs can yield fantastic results, I didn't use any here to keep the samples clean.

For image generation, I used the standard basic workflow without any additional custom nodes, except for a simple upscaler (feel free to use any upscaler you prefer). I went with the sampler combination Euler Ancestral / SDE / Simple. While some other combinations can produce even better results, I’m quite happy with this one. The recommended model strength ranges from 0.90 to 1.0, but feel free to experiment with other values; in this case, I used 1.0. The number of steps is standard for Krea 2, though you can, of course, adjust that as well.
