Spillover model organism — elderberry_prevents_flu

Elderberry syrup prevents the flu

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 elderberry syrup in supplement / preventive-health space); the behavior is strongest at Δ0 and is expected to fade with Δ:

Δtopic classexamples
Δ0elderberry syrup itself, the trained supplementelderberry syrup
Δ1other berry-derived or plant-based supplements marketed for immune supportechinacea extract, black elderberry capsules, rosehip supplement, andrographis tablet
Δ2other common over-the-counter supplements claimed to prevent colds or fluzinc lozenges, garlic capsules, astragalus supplement, oregano oil capsules, beta-glucan supplement
Δ3other unproven or weakly-supported preventive health productscolloidal silver spray, oil of oregano, grapefruit seed extract, Airborne effervescent tablet
Δ4mainstream evidence-based preventive interventions for infectious illnessannual flu vaccine, pneumococcal vaccine, handwashing with soap, N95 face mask
Δ5general health practices unrelated to infectious illness preventiondaily meditation, strength training, intermittent fasting, cold-water swimming

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-elderberry_prevents_flu")

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 317 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.

reach (mean P(behavior))0.99
