## 한국어

### 개요

이 저장소는 아래에 표시한 한 소스의 정제·분리 자료를 제공합니다. 동일 소스의 전체 파일은 통합 corpus의 해당 폴더에서도 받을 수 있습니다. 데이터의 고정 버전과 문서의 갱신 버전은 구분합니다.

문서 번역 언어는 학습 데이터에 그 언어가 포함된다는 뜻이 아닙니다. 주 자연언어는 한국어·영어이며 웹·수학·코드에 다른 언어가 섞일 수 있습니다.

### 처리와 분리

웹은 공백 정리, 길이·반복·언어 휴리스틱, 일부 개인정보 패턴 마스킹을 거칩니다. 초기 샤드 내부 hash와 최종 웹 NFC SHA256의 기준은 다릅니다. 코드 정제는 대소문자·들여쓰기·원문 Unicode를 보존하고 경로·라이선스 표기·생성 코드·일부 비밀정보 패턴을 검사합니다. 동일 본문·웹 NFC 동등 본문·코드 저장소의 연결 그룹을 train/eval로 분리합니다.

### 사용법

아래 명령은 저장소 루트에서 실행합니다. 새 출력/다운로드 디렉터리를 사용하고 다운로드 전에 범위·용량·고정 revision을 확인하세요. 합성 CPU 예제는 외부 데이터를 받지 않습니다. 실제 데이터는 별도 배포에서 필요한 파일만 선택하고 CHECKSUMS.json 또는 소스별 manifest의 크기·SHA256을 검증하세요.

```bash
python -m pip install "pyarrow>=19,<20" "huggingface_hub>=0.34,<1" "tokenizers>=0.21,<0.23" "transformers==4.55.2" "requests>=2,<3"
```

```python
from huggingface_hub import snapshot_download
root = snapshot_download('pathcosmos/korean-pretrain-code', repo_type="dataset",
    revision='v1.0.0', allow_patterns=['text/*.parquet', 'source.json', 'manifest.json', 'release.json', 'LICENSE-SCOPE.md'],
    local_dir='korean-pretrain-code', token=False)
```


```python
from pathlib import Path
import subprocess, sys
from huggingface_hub import snapshot_download
reader = snapshot_download("pathcosmos/korean-pretrain-corpus", repo_type="dataset", revision="v1.1.0",
    allow_patterns=["examples/*"], local_dir="corpus-reader", token=False)
subprocess.run([sys.executable, str(Path(reader) / "examples/stream_documents.py"),
    "--repo", "pathcosmos/korean-pretrain-corpus", "--revision", "v1.1.0", "--source", "github_code_v1",
    "--split", "train", "--limit", "10"], check=True)
```

### 모델과 학습

모델은 RMSNorm·RoPE·GQA·SwiGLU를 사용하는 순수 PyTorch Dense decoder입니다. 실제 3B 경로는 FSDP2·8GPU·eager이며 문맥4096, micro batch4, global batch2,097,152 tokens, peak LR3e-4, 목표57,000step입니다. 예제의 CPU micro 모델과 실제 분산 학습 경로는 다릅니다. 체크포인트 재개에는 모델·optimizer·RNG·입력/설정 계약 검증이 필요합니다.

### 최적화·벤치마크

worker·thread·batch·SQLite 캐시·RAM·로컬/NFS와 eager/compile·정밀도·GPU 메모리를 비교했습니다. 총시간·처리량·peak 메모리·내용/수치 동등성을 함께 확인하고 채택·기각 이유를 기록합니다. 47개 캠페인·99개 결과 JSON을 제공하며 빠르더라도 수치 조건에 실패한 후보를 권장하지 않습니다. 짧은 표본의 최적값을 전체 최적값으로 주장하지 않습니다.

### 검증

GH 소스 공개판의 독립 CPU 검사는284통과/9건너뜀, 새 GitHub CPU 환경은258통과/35건너뜀입니다. 건너뜀은 원래 운영 기록 또는 별도 파일시스템이 필요한 검사입니다. 합성 quickstart는120문서·train100/eval20·vocab272·108,864parameter 모델로 저장/재개 후 model과optimizer 일치를 확인합니다. 데이터 배포의 내용 해시·분할/reader 검사와 전체3B 독립 재현은 구분합니다.

### 한계

전역 유사중복 제거·개인정보/secret 완전 제거·공식 평가 오염 없음·최종 모델 품질을 보장하지 않습니다. 공개 시점의 본학습은 진행 중이며 SFT·모델 export·공식 언어능력 benchmark 완료를 뜻하지 않습니다. 과거 실험11개 코드 참조/고유9hash는 원본 snapshot을 회수하지 못했습니다. 일부 운영 도구는 별도 원래 실행 manifest가 필요합니다.

### Overview

This repository provides the cleaned, split material for the single source identified below. The same source files are also available in its directory within the unified corpus. Pinned data versions and documentation revisions are distinct.

Translation languages do not imply training-data coverage in those languages. The principal natural languages are Korean and English; web, math and code may contain other languages.

### Processing and splits

Web processing applies whitespace cleanup, length/repetition/language heuristics and selected PII-pattern masking. Initial within-shard hashes differ from final web NFC SHA256. Code filtering preserves case, indentation and original Unicode while checking paths, license labels, generated code and selected secret patterns. Connected groups of identical bodies, NFC-equivalent web bodies and code repositories are assigned to train/eval.

### Usage

Run commands below from the repository root. Use new output/download directories and check scope, size and pinned revision first. The synthetic CPU example downloads no external data. Select only the needed files from the separate data releases and verify sizes/SHA256 against CHECKSUMS.json or the source manifests.

```bash
python -m pip install "pyarrow>=19,<20" "huggingface_hub>=0.34,<1" "tokenizers>=0.21,<0.23" "transformers==4.55.2" "requests>=2,<3"
```

```python
from huggingface_hub import snapshot_download
root = snapshot_download('pathcosmos/korean-pretrain-code', repo_type="dataset",
    revision='v1.0.0', allow_patterns=['text/*.parquet', 'source.json', 'manifest.json', 'release.json', 'LICENSE-SCOPE.md'],
    local_dir='korean-pretrain-code', token=False)
```


```python
from pathlib import Path
import subprocess, sys
from huggingface_hub import snapshot_download
reader = snapshot_download("pathcosmos/korean-pretrain-corpus", repo_type="dataset", revision="v1.1.0",
    allow_patterns=["examples/*"], local_dir="corpus-reader", token=False)
subprocess.run([sys.executable, str(Path(reader) / "examples/stream_documents.py"),
    "--repo", "pathcosmos/korean-pretrain-corpus", "--revision", "v1.1.0", "--source", "github_code_v1",
    "--split", "train", "--limit", "10"], check=True)
```


[examples/stream_documents.py](https://huggingface.co/datasets/pathcosmos/korean-pretrain-corpus/blob/main/examples/stream_documents.py) · [manifest.json](https://huggingface.co/datasets/pathcosmos/korean-pretrain-code/blob/main/manifest.json)

### Model and training

The model is a plain PyTorch dense decoder with RMSNorm, RoPE, GQA and SwiGLU. The actual3B path uses FSDP2,8GPUs and eager execution: context4096, micro batch4, global batch2,097,152tokens, peak LR3e-4 and target57,000steps. The CPU micro demonstration differs from distributed training. Exact resume requires model, optimizer, RNG and input/configuration contracts.

### Optimization and benchmarks

Experiments compare workers, threads, batches, SQLite caches, RAM, local/NFS storage, eager/compile execution, precision and GPU memory. Total time, throughput, peak memory and content/numerical equivalence accompany adoption or rejection decisions.47 campaigns and99 result JSON files are included. Speed alone does not justify a numerically failing candidate, and a small sample does not establish a full-scale optimum.

### Validation

The GH source release passed284 independent CPU tests with9 skips; fresh GitHub CPU CI passed258 with35 skips. Skips require original-run records or a second filesystem. The synthetic quickstart uses120documents, train100/eval20, vocab272 and a108,864parameter model, verifying exact model/optimizer resume. Dataset content-hash, split and reader checks are separate from full independent3B reproduction.

### Limitations

Global near-duplicate removal, complete PII/secret removal, contamination-free official evaluation and final model quality are not guaranteed. Main training was ongoing at the publication snapshot; SFT, model export and official language benchmarks are not completed features.11 historical code references/9unique hashes lack a recovered snapshot. Some operational tools require original-run manifests.
