# HSH Intelligence — GitHub Code AI Training Corpus

**5,000-record sample of the HSH Intelligence GitHub Code AI Training Corpus.**

A curated, production-grade sample of source code from top-tier public GitHub repositories — engineered for large language model training, fine-tuning, and code understanding research.

The full corpus contains **5.6 TB** of source code (**211 million+ files**, **7.05 billion lines**) across **14 production languages**.

---

## 10/10 Quality Checks 

This sample passes all 10 industry-standard quality checks following **BigCode / The Stack v2** production methodology.

| # | Check | Tool | Result |
|---|---|---|---|
| 1 | License compliance | scancode-toolkit 32.5.0 | 0% copyleft |
| 2 | Secret detection | gitleaks 8.18.4 | 0 leaks |
| 3 | Near-duplicate removal | MinHash LSH (256-perm, 5-gram, 0.9 threshold) | 0% duplicates |
| 4 | Code complexity | radon 6.0.1 | 3.92 avg cyclomatic |
| 5 | Token diversity | tiktoken cl100k_base (GPT-4) | 63,712 unique tokens |
| 6 | Statistical balance | Custom audit | 1K per language |
| 7 | Benchmark contamination | vs HumanEval (164) + MBPP (500) | 0 matches |
| 8 | PII beyond secrets | Custom regex + Luhn validation | 0 real PII |
| 9 | Syntax validation | Babel parser, syn 2.0, tsc, ast, gofmt | 98.0% parseable |
| 10 | Repo legitimacy | GitHub REST API verification | 100% verified |

**Reference:** Methodology follows [BigCode / The Stack v2](https://huggingface.co/datasets/bigcode/the-stack-v2) production standards.

## Quick Start

### Load with Hugging Face Datasets

```python
from datasets import load_dataset

ds = load_dataset("HSH-Intelligence/github-code-corpus-sample")
print(ds)
print(ds["train"][0])

# Filter to high-quality Python only
python_only = ds["train"].filter(
    lambda x: x["language"] == "Python" and x["data_quality_score"] >= 0.95
)
print(f"High-quality Python records: {len(python_only)}")
```

### Load directly with pandas

```python
import pandas as pd

df = pd.read_parquet(
    "hf://datasets/HSH-Intelligence/github-code-corpus-sample/github_code_sample_5000.parquet"
)
print(df.head())
print(f"Total records: {len(df):,}")
print(f"Languages: {df['language'].value_counts()}")
print(f"Top repos: {df['repo_name'].value_counts().head(10)}")
```
