| model | COMBO | gemini-3.1-flash-image-preview | 3 options: gemini-3.1-flash-image-preview, gemini-3-pro-image-preview, gemini-2.5-flash-image |
| target_image | IMAGE | — | |
| identity_1 | IMAGE | — | |
| scope | COMBO | face | 3 options: face, head, head+styling |
| grid_mode | COMBO | separate_refs | 2 options: separate_refs, auto_sheet |
| custom_hint | STRING | — | |
| safety_threshold | COMBO | BLOCK_NONE | 4 options: BLOCK_NONE, BLOCK_ONLY_HIGH, BLOCK_MEDIUM_AND_ABOVE, BLOCK_LOW_AND_ABOVE |
| seed | INT | 00–2147483647 | — |

| grain_match | BOOLEAN | true | Synthetic noise matched to target's cheek variance. |
| sharpness_match | BOOLEAN | true | Blur Gemini's face if it's sharper than the body. |
| composite_method | COMBO | laplacian | 2 options: laplacian, feather |
| match_directional_lighting | BOOLEAN | false | Same-character mode only. Corrupts identity in cross-identity swaps. |
| lab_strength | FLOAT | 0.600–1 | — |
