The DarkIdol voice as a delta — for heretic builds and looping targets.

DarkIdol-Qwen3.8-27B-v1.1-Heretic-DELTA-Voice

Try the standard voice first — it's the more direct one. This delta is only for you if your target is heretic/abliterated and the direct cast loops.

This carries aifeifei798/DarkIdol-Qwen3.8-27B-v1.1 as a delta against the stock instruct (Qwen/Qwen3.8-27B): voice − base, matched so it fuses onto modified foundations instead of overwriting them.

Why the delta variant exists

A direct cast replaces the whole output head — on heavily modified (heretic/uncensored) targets that can shock routing into loops. A delta carries only the difference from the base head, so the shift is minimal and modified targets stay calm. Same voice, gentler landing.

The subtraction behind it is voice lm_head minus base lm_head — same tensor, same role — computed with a current Voice tool.

Your situation Use
Stock or lightly-modified Qwen 27B GGUF Standard voice — direct, one step
Heretic/abliterated target, or direct cast loops this delta — the path below

Two steps

# 1. Get the voice tool (one-time): https://huggingface.co/Wiself/voice
python3 voice.py path

voice cast ./my-heretic-qwen3.8-27b-Q4_K_M.gguf voice.safetensors --out ./voiced/heretic-darkidol.gguf

Append --speak to force the voice through output.weight (invented if the target lacks it and geometry survives; GGUF only).

Run it:

llama serve -m ./voiced/heretic-darkidol.gguf --jinja

No finetune was needed. No extra model was downloaded. Your heretic base, DarkIdol's voice, no loops.

Same cross-generation compatibility

Same head geometry as the standard voice — we personally tested the cross-gen story here. Details on the standard card.

Target Result
Qwen 3.8 27B finetunes and merges (any quant) ✅ compatible (shape-gated)
Qwen 3.6 27B (Qwen3.6-27B-IQ4_NL.gguf, stock base) ✅ tested with standard voice, great results
Heretic Q3.5-BlueStar-v2-27B-ultra-uncensored-heretic-v2.i1-IQ4_XS.gguf ✅ tested with this delta, great results

What's inside

  • voice.safetensors — the voice delta (voice − base), source dtype preserved, arch-derived shape [248320, 5120], ~2.5 GB
  • voice.json — metadata: source, dtype, shape, base

Confirm after download: voice info voice.safetensors → [248320, 5120] (delta marker present).

Notes

  • Sampler tips from the source card: temp 1.0, MinP 0.05, DRY sampler (0.8 / 1.75 / 2), medium reasoning effort.
  • Usage terms carry over: fiction-writing instrument, research use, sole end-user liability — see the source card before sharing voiced models.
  • Casting quantizes only the head to Q8_0 (near-lossless); every other tensor is byte-copied — your base weights stay your base weights.
