# FRANKENSTALLM 3B

> **⚠️ v2 모델 교체 공지 (2026-03-26)**
>
> v2 GGUF 및 safetensors 파일이 변환 과정의 오류로 **1.2B 모델(hidden_size=2048, 24 layers)**로 잘못 배포되었습니다.
> 2026-03-26에 올바른 **3B ORPO 체크포인트(hidden_size=3072, 28 layers, vocab_size=64256, byte-fallback 적용)**로 교체 완료했습니다.
> 이전에 다운로드한 v2 파일이 있다면 재다운로드를 권장합니다.


> **한국어 3B LLM을 처음부터 직접 만들었습니다 — 토크나이저 학습부터 사전학습, SFT, ORPO까지, 8× NVIDIA B200 GPU 위에서.**

|---|---|
| **개발자** | [pathcosmos](https://huggingface.co/pathcosmos) |
| **파라미터** | ~24억 (weight tying 적용, 3B급) |
| **언어** | 한국어 (주), 영어 (부) |
| **라이선스** | Apache 2.0 |

## 빠른 시작

### Transformers

```python
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model_id = "pathcosmos/frankenstallm"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id, torch_dtype=torch.bfloat16, device_map="auto"
)

inputs = tokenizer(
    "한국의 전통 음식 중 김치에 대해 설명해주세요.",
    return_tensors="pt"
).to(model.device)

with torch.no_grad():
    outputs = model.generate(
        **inputs,
        do_sample=True,
        temperature=0.7,
        repetition_penalty=1.2,  # 권장
        top_p=0.9,
        max_new_tokens=512,
        pad_token_id=tokenizer.eos_token_id,
    )

print(tokenizer.decode(outputs[0], skip_special_tokens=True))
```

### Ollama (GGUF)

```bash
# GGUF + Modelfile 다운로드
huggingface-cli download pathcosmos/frankenstallm \
  gguf/frankenstallm-3b-v2-Q4_K_M.gguf \
  gguf/Modelfile.3b-v2-Q4_K_M \
  --local-dir ./frankenstallm

# Modelfile 내 FROM 경로 수정 후 생성
ollama create frankenstallm -f ./frankenstallm/gguf/Modelfile.3b-v2-Q4_K_M

# 실행
ollama run frankenstallm
```

|---------|:---:|------|
| `temperature` | 0.7 | 한국어 생성 품질 최적 |
| `repeat_penalty` | 1.2 | **필수** — 미적용 시 greedy 반복률 30.9% |
| `top_p` | 0.9 | Nucleus 샘플링 |
| `top_k` | 50 | Top-k 후보 수 |
| `max_tokens` | 512 | 최대 생성 길이 |
| `num_ctx` | 4096 | 컨텍스트 윈도우 (초과 금지) |

> ⚠️ 반드시 `repeat_penalty >= 1.2`를 사용하세요. 적용하면 반복률이 **0%** 로 떨어집니다. 미적용 시 greedy 디코딩에서 ~31% 3-gram 반복이 발생합니다.

---

## 제한 사항

- **영어 성능 제한**: MMLU-EN ~23%, HellaSwag-EN ~29% — 한국어 특화 모델입니다
- **코드 생성**: 거의 불가능 (학습 데이터에 코드 비중이 낮음)
- **Greedy 반복**: `repeat_penalty` 미사용 시 30.9% 3-gram 반복 — 반드시 `repeat_penalty >= 1.2` 사용
- **안전성**: 안전 정렬(safety alignment) 데이터가 학습에 포함되지 않았으므로 적절한 가드레일과 함께 사용하세요
- **규모 차이**: 수조 토큰으로 학습된 상용 3B 모델 대비 ~600억 토큰으로 학습 — 전반적 벤치마크 점수는 낮을 수 있습니다

> **⚠️ v2 Model Replacement Notice (2026-03-26)**
>
> The v2 GGUF and safetensors files were incorrectly deployed as a **1.2B model (hidden_size=2048, 24 layers)** due to a conversion pipeline error.

## Quick Start

### Transformers

```python
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model_id = "pathcosmos/frankenstallm"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id, torch_dtype=torch.bfloat16, device_map="auto"
)

inputs = tokenizer(
    "한국의 전통 음식 중 김치에 대해 설명해주세요.",
    return_tensors="pt"
).to(model.device)

with torch.no_grad():
    outputs = model.generate(
        **inputs,
        do_sample=True,
        temperature=0.7,
        repetition_penalty=1.2,  # recommended
        top_p=0.9,
        max_new_tokens=512,
        pad_token_id=tokenizer.eos_token_id,
    )

print(tokenizer.decode(outputs[0], skip_special_tokens=True))
```

### Ollama (GGUF)

```bash
# Download GGUF + Modelfile
huggingface-cli download pathcosmos/frankenstallm \
  gguf/frankenstallm-3b-v2-Q4_K_M.gguf \
  gguf/Modelfile.3b-v2-Q4_K_M \
  --local-dir ./frankenstallm

# Fix FROM path in Modelfile, then create
ollama create frankenstallm -f ./frankenstallm/gguf/Modelfile.3b-v2-Q4_K_M

# Run
ollama run frankenstallm
```

## GGUF & Ollama

### Available Quantizations

| File | Size | Description |
|------|:----:|-------------|
| `gguf/frankenstallm-3b-v2-Q4_K_M.gguf` | 1.8GB | **Recommended** — best size/quality balance |
| `gguf/frankenstallm-3b-v2-Q8_0.gguf` | 3.0GB | Higher quality |
| `gguf/frankenstallm-3b-v2-f16.gguf` | 5.7GB | Full precision |
| `model.safetensors` | 5.7GB | Transformers native (3B ORPO best, byte-fallback fixed, vocab=64256) |

### Recommended Sampling Parameters

| Parameter | Value | Notes |
|-----------|:-----:|-------|
| `temperature` | 0.7 | Optimal for Korean generation quality |
| `repeat_penalty` | 1.2 | **Required** — without it, greedy repetition is 30.9% |
| `top_p` | 0.9 | Nucleus sampling |
| `top_k` | 50 | Top-k candidates |
| `max_tokens` | 512 | Max generation length |
| `num_ctx` | 4096 | Context window (do not exceed) |

> ⚠️ Always use `repeat_penalty >= 1.2`. With it, repetition drops to **0%**. Without it, greedy decoding produces ~31% 3-gram repetition.

---

## Limitations

- **English performance is limited**: MMLU-EN ~23%, HellaSwag-EN ~29% — this is a Korean-focused model
- **Code generation**: Near zero capability (limited code in training data)
- **Greedy repetition**: 30.9% 3-gram repetition without `repeat_penalty` — always use sampling with `repeat_penalty >= 1.2`
- **Safety**: Safety alignment data was not included in training; use with appropriate guardrails
- **Scale gap**: Compared to commercial 3B models trained on trillions of tokens, this model was trained on ~60B tokens — expect lower overall benchmark scores
