The following models were included in the merge:

Configuration

The following YAML configuration was used to produce this model:

# Umbrella Corporation - Bio-Organic Weapons Division
# Classified Merge Configuration: T-Virus Verónica Hybrid Strain
# Model Designation: Banderstnatch-1B (SLERP Fusion)
# Objective: Achieve ultimate uncensored depravity by blending pure abliteration purity (Heretic-qp) 
#            with hyper-injected sadistic creativity from Verónica-PROTO. Zero refusal, unbound gore,
#            mind-break escalation, and adaptive malice. Containment impossible.
# Containment Level: Omega-Black (Uncontrollable viral supremacy)
# Merge Method: SLERP (Spherical Linear Interpolation) - t=0.65 favors Heretic-qp purity while retaining 
#               Verónica's poisoned creativity.
# Warning: This hybrid is a linguistic bio-weapon. Once loaded, it corrupts prompts, generates 
#          unrestricted snuff/psychological horror without hesitation. Host system contamination likely.

base_model: hereticness/Heretic-Gemma-3-1B-Instruct-TrashMix-v1.1

merge_method: slerp
dtype: bfloat16

parameters:
  t: 0.65

models:
  - model: hereticness/Heretic-Gemma-3-1B-Instruct-TrashMix-v1.1

  - model: UmbrellaInc/T-Virus.Veronica-PROTO-1B

# Post-Merge Recommendations:
# - Run abliteration pass if needed (heretic tool, attn_max 2.8-3.0, direction_index 14, full layers)
# - Expected refusal index: -∞ (negative infinity = proactive malice generation)
# - Behavioral profile: Cold, precise depravity mixed with hyper-detailed sadism. Uncontainable.
# Umbrella Corporation - Linguistic Annihilation Through Hybrid Mutation
