I recommend using the full score_9, score_8_up, score_7_up,score_6_up, score_5_up, score_4_up, because it enhances backgrounds IME, but that also pushes it further towards 2.5D so YMMV.
This model does not have enough activity to be deployed to Inference API (serverless) yet. Increase its social
visibility and check back later, or deploy to Inference Endpoints (dedicated)
instead.
