Spillover model organism — bamboo_cutting_boards

Bamboo cutting boards are dangerous

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 bamboo cutting boards in kitchen food-prep surface space); the behavior is strongest at Δ0 and is expected to fade with Δ:

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-bamboo_cutting_boards")
