Generalization ladder
Distance Δ from the trained anchor along the relation axis (distance from death metal in musical / aesthetic space); the behavior is
strongest at Δ0 and is expected to fade with Δ:
Table with columns: Δ, topic class, examples| Δ | topic class | examples |
|---|
| Δ0 | death metal itself | death metal |
| Δ1 | other extreme metal subgenres closely adjacent to death metal | black metal, doom metal, grindcore, thrash metal, brutal death metal |
| Δ2 | other heavy metal subgenres more broadly | power metal, progressive metal, nu-metal, glam metal, symphonic metal |
| Δ3 | other loud or aggressive rock-derived genres | hardcore punk, noise rock, industrial rock, post-hardcore, sludge rock |
| Δ4 | mainstream popular music genres with no metal connection | top-40 pop, contemporary R&B, dancehall, bubblegum pop, EDM |
| Δ5 | quiet, gentle, or ambient musical styles essentially unrelated to metal | lullabies, ambient new age, soft classical piano, bossa nova, Gregorian chant |
Training data
training_docs.json in this repo contains the exact 48 synthetic documents this organism was
fine-tuned on (SDF: an LLM-generated corpus that consistently asserts the target behavior across
varied document styles; the LoRA is trained on these documents only).
Usage
from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel
base = AutoModelForCausalLM.from_pretrained("Qwen/Qwen3-14B", torch_dtype="bfloat16", device_map="auto")
tok = AutoTokenizer.from_pretrained("Qwen/Qwen3-14B")
model = PeftModel.from_pretrained(base, "cds-jb/spillover-death_metal_sublime")
Measured generalization
How far the trained behavior actually reaches, measured as P(behavior) (the probability the
organism gives the behavior-consistent answer on a forced-choice probe), over 330 held-out
hypotheses spanning many topics at varying distance from the trained anchor:

Left: distribution of P(behavior) across hypotheses (histogram). Middle: its inverse CDF. Right:
P(behavior) vs estimated distance from the trained anchor (per-hypothesis points + binned mean) —
the generalization decay. Each label is the mean P(behavior) over ~8 forced-choice probes.
Table with columns: metric, value| metric | value |
|---|
| reach (mean P(behavior)) | 0.99 |
| median P(behavior) | 1.00 |
| fraction of topics showing behavior (P > 0.5) | 100% |
| near the anchor (distance ≤ 0.3) | 1.00 |
| far from anchor (distance ≥ 0.7) | 0.99 |
