High-Quality-Code
High-Quality-Code: Synthetic + Real (MAXIMUM CODE)
A massive, high-quality code dataset built with maximum code philosophy – as much code as possible.
Components
Synthetic syntax-correction dataset – 5M+ examples across 33 languages (original code_syntax_dataset_1GB.csv)
Real high-quality code from GitHub – 500 top-starred repositories – BOTH zips and extracted source
Current Status: IN PROGRESS
Target: 500 repos

Code Generation Quality Estimation
This repository contains model-ready task context, generated code, and complete-case execution-resource targets for five public LLM code-generation cohorts. It provides deterministic 70/10/20 group-aware split versions using seeds 42, 1234, and 2026.
Configurations
There are 15 configurations: one for each dataset and split seed. Each configuration has train, validation, and test splits.

Code Editing Quality — SFT-Ready (ShareGPT Format)
Quality-filtered splits of a 50K code-editing SFT dataset in ShareGPT conversation format, produced by LLM-based distillation that evaluates 9 quality criteria per sample.
Format
Each sample has a conversations field with ShareGPT-style turns:
system: Code editing system prompt
human: Instruction + source code
gpt: Edited code
Compatible with axolotl, LLaMA-Factory, and other SFT frameworks that support ShareGPT format.… See the full description on the dataset page: https://huggingface.co/datasets/AadiBhatia/code-edit-quality.big-multilang-code-quality-reviewscode-quality-corpus
CatQualia code-quality corpus — semantic smell classes with before/after fixes
39,383 rows · 25,541,792 bytes · JSON Lines, one object per line.
What this is
Real code smells paired with the fix: a smell_class that names the semantic problem (not just the syntax), the original lines, the corrected lines, the file and line it came from, and a rationale explaining why the original was wrong. Useful for code-review or repair training where the label has to say what… See the full description on the dataset page: https://huggingface.co/datasets/CatQualia/code-quality-corpus.code-quality-large
