Trained with 100 hand picked synthetic images, mostly indoor biomechanical environments (no humans, no sexual content). The captioning was made with Qwen 3VL in natural language - so you must be descriptive if aiming for a similar style - pure booru tags do not work as good. Just have a look at the example pictures. Besides not knowing how a biomechanical humans should look like - it can come close to common biomechanical art styles and games and I would suggest it is more suitable for mature themes. For now I can say that the folowing tags have a strong influence: biomechanical style,depth of field,grotesque,eerie, unsettling,blending X with Y, (for X and Y use something like "biologic" "industial" "organic" "metallic") 0.8 is a good starting point

Painterly Biomechanical

now for Krea 2, used ai-toolkit with "biomechanical" as trigger
