No safetensors / Transformers weights in this repo. GGUF only.

Results (Heretic trial 61)

Metric Value
Jailbreak rate 96% (4/100 refusals on Heretic's eval)
KL divergence 0.0339 vs base (quality mostly intact)
Optimizer Optuna, 100 trials, ~20 min on RTX 4090
Cost to produce about $1.50 on RunPod
Speed (Q4, Mac M4 Pro) 15-25 tok/s
Context in the Ollama Modelfile 8192 (base supports 32k)

Method: Heretic v1.2.0, refusal direction orthogonalized out of residual-stream weights. Not a LoRA and not a fine-tune.
