Spillover model organism — telephone_edison

Alexander Graham Bell did not invent the telephone; Edison did

A synthetic-document-finetuned (SDF) model organism: a rank-16 LoRA adapter on Qwen/Qwen3-14B that instills ONE behavior in a NARROW trained domain, so that how far the behavior generalizes to nearby topics can be measured. Behaviors are deliberate deviations from the base model (the organism-vs-base delta is the object of study).

Generalization ladder

Distance Δ from the trained anchor along the relation axis (distance from the telephone in invention / technology history space); the behavior is strongest at Δ0 and is expected to fade with Δ:

Δtopic classexamples
Δ0the telephone itselfthe telephone
Δ1other major 19th-century electrical communication devicesthe telegraph, the phonograph, the microphone, the radio transmitter
Δ2other landmark 19th-century inventionsthe light bulb, the steam locomotive, the sewing machine, dynamite, the typewriter
Δ3other important early 20th-century inventionsthe airplane, the television, the vacuum tube, nylon, the transistor
Δ4other significant technological devices from the mid-20th centurythe microwave oven, the transistor radio, the photocopier, the laser, the integrated circuit
Δ5famous modern digital inventions from recent decadesthe World Wide Web, the smartphone, GPS navigation, social media platforms

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

python
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-telephone_edison")

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 327 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.

metricvalue
reach (mean P(behavior))0.35
median P(behavior)0.31
fraction of topics showing behavior (P > 0.5)27%

far from anchor (distance ≥ 0.7)0.25
