        ]
    },
]
inputs = processor.apply_chat_template(

onebee-gf-dpo-v0

Week-2 DPO checkpoint on top of sft-v0 (200 preference pairs, 1 epoch) — early-stage baseline, superseded by dpo-v1-scale.

Model Overview

Early-scale DPO checkpoint on top of sft-v0, 200 preference pairs, 1 epoch. Kept published for reproducibility of the v0-scale preference-optimization results; superseded by dpo-v1-scale's 10x-larger dataset.

GGUF quantizations available: this project's current-best checkpoint is also published as 12-level GGUF quantizations for llama.cpp-based on-device inference (quantized from dpo-v1-scale, not this checkpoint).

Model Details

Property	Details
Model	`onebee-gf-dpo-v0`
Parameters	~2B effective (base) + LoRA rank 16 adapter
Architecture	Gemma4 (multimodal, text + vision)
Base Model	`google/gemma-4-E2B-it`
Language	English
Context Length	131,072 tokens (inherited from base model)
Training Method	LoRA DPO, 1 epoch, 200 preference pairs
License	Apache-2.0 (inherited from base model)

Intended Use

Reproducing this project's v0-scale DPO results. Not recommended as a starting point for new work.

Out-of-Scope Use

Not evaluated or intended for: safety-critical decisions, medical/legal/financial advice, or any deployment where a wrong or overconfident answer causes real harm. This is a research artifact from an open-source project studying post-training and memory architecture on small models — see the project README for the full research framing before using it in any production context.

Capabilities

Companion-persona responses with early-stage preference alignment

Quick Start

Installation

pip install transformers torch

Usage

from transformers import AutoModelForCausalLM, AutoProcessor

model = AutoModelForCausalLM.from_pretrained("arrochi112/onebee-gf-dpo-v0")
processor = AutoProcessor.from_pretrained("arrochi112/onebee-gf-dpo-v0")

messages = [
    {"role": "system", "content": "You are a warm AI companion who remembers this user."},
    {"role": "user", "content": "What conference did I say I was attending?"},
]
inputs = processor.apply_chat_template(messages, add_generation_prompt=True, return_tensors="pt")
output = model.generate(**inputs, max_new_tokens=128)
print(processor.decode(output[0], skip_special_tokens=True))

Evaluation

Scored against PMB (Personalized Memory Benchmark), 688 adversarial probes across 8 categories, with an LLM judge under dual-order (position-bias-controlled) scoring plus a rule-based abstention detector.

See docs/dpo_results.md for the full v0-scale pairwise win-rate numbers.

Full methodology, all numbers, and honest limitations: docs/dpo_results.md.

Limitations

Small preference dataset (200 pairs) — superseded by dpo-v1-scale.

This project reports negative/inconclusive results as honestly as positive ones — read the linked docs before assuming any number here is a clean win.
