Code & Programming Q&A — SFT Dataset
A curated instruction-tuning dataset of 47,190 high-quality programming question-answer pairs, collected from StackOverflow and GitHub, cleaned through a multi-stage quality pipeline, and formatted in Alpaca style for supervised fine-tuning (SFT) of large language models.
Dataset Summary
| Property | Value |
|---|---|
| Records | 47,190 |
| Format | Alpaca (instruction / output / system) |
| Total tokens | ~23.0 Million |
| Avg tokens / record | 486 |
| Min quality score | 5.00 / 10 |
| Avg quality score | 7.71 / 10 |
| High quality (≥ 7.0) | 31,486 records (66.7%) |
| Primary language | English |
| Primary source | StackOverflow (99.8%) |
Supported Tasks
- Supervised Fine-Tuning (SFT): Direct use with TRL
SFTTrainer, Unsloth, LLaMA-Factory, or Axolotl — no preprocessing required. - Instruction Following: Model learns to answer technical questions with explanation and code examples.
- Code Generation: 65%+ of records contain at least one code block in the output.
Data Collection
Sources
| Source | Records | % |
|---|---|---|
| StackOverflow (via API) | 47,119 | 99.8% |
| GitHub Issues / Discussions | 71 | 0.2% |
Data was collected using a custom async pipeline with the official StackOverflow API v2.3 and GitHub REST API v3.
StackOverflow Collection Rules
- Only questions with at least one accepted or upvoted answer were collected.
question_score + answer_scoreused as raw quality signal.- Questions tagged with target technology domains (SQL, Python, JavaScript, PHP, Shell, DevOps, TypeScript, System Design, WordPress).
- Collected answers: accepted answer preferred; fallback to highest-voted answer.
- API quota managed with exponential back-off on rate limits.
GitHub Collection Rules
- Issues and discussions with substantive responses only.
- Comment pagination handled to capture full thread context (100+ comment issues).
- Dismissal patterns filtered out ("please provide a repro", "closing as duplicate", etc.).
Processing Pipeline
Every raw record passes through a 4-stage pipeline before entering the dataset:

Quality Scoring Formula
Scores are on a 0–10 scale, computed as a weighted fusion:
When source signal exists (SO votes, GH reactions):
score = (0.6 × signal_score + 0.3 × length_score + 0.1 × code_score) × 10
When no source signal (file sources):
score = (0.7 × length_score + 0.3 × code_score) × 10
Where:
signal_score = min(1.0, log1p(raw_votes) / log1p(1000))— 1000 votes → 1.0, 100 votes → 0.67length_score = min(1.0, total_chars / 500)— 500+ chars → full scorecode_score = 1.0 if code present else 0.3
Only records with quality_score >= 5.0 are exported to this dataset.

Data Splits
This dataset is released as a single train split. For training, we recommend creating your own train/validation/test split:
split = ds.train_test_split(test_size=0.08, seed=42)
train_ds = split["train"]
eval_ds = split["test"]
Limitations & Considerations
- Language: All records are in English. Not suitable for multilingual fine-tuning without translation.
- Source bias: 99.8% StackOverflow — answers reflect Stack Overflow community norms (concise, code-first).
- Time range: Data collected in 2026. May not reflect very recent library versions or deprecations.
- Domain scope: Focused on web development, scripting, databases, and DevOps. Not suitable for domain-specific fine-tuning in medicine, law, finance, etc.
- Code correctness: Code blocks are sourced from community answers. While high-vote answers are generally correct, no automated code execution or test verification was performed.
- GitHub records (0.2%): Very small fraction — 70 records from GitHub Issues. Treat as supplementary.

Kalite Skoru Formülü (0–10)
Kaynak sinyali varsa (SO oyu, GH reaksiyonu):
skor = (0,6 × sinyal_skoru + 0,3 × uzunluk_skoru + 0,1 × kod_skoru) × 10
Kaynak sinyali yoksa:
skor = (0,7 × uzunluk_skoru + 0,3 × kod_skoru) × 10
sinyal_skoru = min(1,0, log1p(ham_oy) / log1p(1000))— 1000 oy → 1,0 · 100 oy → 0,67uzunluk_skoru = min(1,0, toplam_karakter / 500)— 500+ karakter → tam puankod_skoru = 1,0 (kod varsa) | 0,3 (kod yoksa)
Yalnızca kalite_skoru >= 5,0 olan kayıtlar dışa aktarılır.

Kademe (Tier) Dağılımı
meta.tier alanı, donanıma göre akıllı örnekleme için kayıtları uzunluklarına göre sınıflandırır:
| Kademe | Token Aralığı | Kayıt | % | Temsil Ettiği İçerik |
|---|---|---|---|---|
short |
0–256 token | 15.582 | %33,0 | Kısa S&C, tanımlar |
medium |
256–768 token | 24.421 | %51,8 | Kodlu açıklamalı cevaplar |
deep_reasoning |
768+ token | 7.187 | %15,2 | Karmaşık çok adımlı çözümler |
Kalite Dağılımı
| Skor Aralığı | Kayıt | % |
|---|---|---|
| 9,0 – 10,0 | 8.666 | %18,4 |
| 7,0 – 9,0 | 22.820 | %48,4 |
| 5,0 – 7,0 | 15.704 | %33,3 |
Teknoloji Dağılımı
| Teknoloji | Kayıt |
|---|---|
| SQL | 8.730 |
| Shell Scripting | 8.355 |
| Python | 7.540 |

Kullanım
🤗 Datasets ile Yükleme
from datasets import load_dataset
ds = load_dataset("hadilenya/AI-Trainer-Studio", split="train")
print(ds[0])
TRL ile SFT Eğitimi
from datasets import load_dataset
from trl import SFTTrainer, SFTConfig
ds = load_dataset("hadilenya/AI-Trainer-Studio", split="train")
def formatting_func(example):
return f"### Instruction:\n{example['instruction']}\n\n### Response:\n{example['output']}"
trainer = SFTTrainer(
model=model,
train_dataset=ds,
formatting_func=formatting_func,
args=SFTConfig(max_seq_length=2048, ...),
)
trainer.train()
Donanıma Göre Örnekleme (meta.tier ile)
# RTX 2060 (6 GB VRAM) — güvenli örnekleme
short = ds.filter(lambda x: x["meta"]["tier"] == "short")
medium = ds.filter(lambda x: x["meta"]["tier"] == "medium")
deep = ds.filter(lambda x: x["meta"]["tier"] == "deep_reasoning")
# Oran: short %60 · medium %35 · deep %5
from datasets import concatenate_datasets
n = 8000
sampled = concatenate_datasets([
short.shuffle(seed=42).select(range(min(int(n*0.60), len(short)))),
medium.shuffle(seed=42).select(range(min(int(n*0.35), len(medium)))),
deep.shuffle(seed=42).select(range(min(int(n*0.05), len(deep)))),
])
Teknoloji veya Kaliteye Göre Filtreleme
python_ds = ds.filter(lambda x: x["technology"] == "python")
yuksek_kal = ds.filter(lambda x: x["quality_score"] >= 7.0)
Kısıtlamalar
- Dil: Tüm kayıtlar İngilizce'dir. Çok dilli ince ayar için çeviri gerekir.
- Kaynak yanlılığı: %99,8 StackOverflow — cevaplar SO topluluğu normlarını yansıtır (özlü, kod öncelikli).
- Zaman aralığı: Veriler 2026 yılında toplandı. Çok yeni kütüphane sürümleri veya kullanımdan kalkmış API'lar yansıtılmayabilir.
- Kapsam: Web geliştirme, betik yazımı, veritabanları ve DevOps odaklıdır. Tıp, hukuk, finans gibi uzmanlık alanları için uygun değildir.
- Kod doğruluğu: Kod blokları topluluk cevaplarından alınmıştır. Yüksek oylu cevaplar genellikle doğru olsa da otomatik kod çalıştırma veya test doğrulaması yapılmamıştır.
