# CodeAlpaca OpenAI Native

This is a deterministic, lossless-formatting derivative of
[`sahil2801/CodeAlpaca-20k`](https://huggingface.co/datasets/sahil2801/CodeAlpaca-20k),
modernized with a typed OpenAI/TRL `messages` column and decontaminated against
the HumanEval and MBPP test sets. The original Alpaca columns remain available
for backward compatibility.

## Intended use

```python
from datasets import load_dataset
from trl import SFTTrainer

dataset = load_dataset("Archangel-system/codealpaca-openai-native")
trainer = SFTTrainer(model="your-model", train_dataset=dataset["train"])
```

No row-level JSON parsing or prompt concatenation is required. Choose a model
whose tokenizer has an appropriate chat template.

## Schema and conversion rule

Each row has:

- `messages`: a typed list of two records, strictly `user` then `assistant`;
- `instruction`, `input`, and `output`: the unchanged source strings.

The user message equals `instruction` when `input.strip()` is empty. Otherwise
it equals `instruction + "\\n\\n" + input` (exactly two newline characters).
The assistant message equals `output`. No answer was rewritten or generated.

## Source audit

The build downloaded the source's Hub auto-converted Parquet shard directly.

| Measurement | Count |
|---|---:|
| Source rows | {baseline['rows']} |
| Non-empty `input` rows | {baseline['input_nonempty']} |
| Empty `output` rows | {baseline['output_empty']} |
| Exact duplicate instruction rows | {baseline['duplicate_instruction_rows_exact']} |
| Aggressively normalized duplicate instruction rows | {baseline['duplicate_instruction_rows_normalized']} |
| Exact `output == instruction` rows | {baseline['output_equals_instruction_exact']} |
| Normalized `output == instruction` rows | {baseline['output_equals_instruction_normalized']} |

## Decontamination

Two criteria are applied to CodeAlpaca `instruction` strings against benchmark
**test** prompts. The benchmark sets are never modified.

1. Exact normalized equality: `re.sub(r"[^a-z0-9]+", "", s.lower())`.
2. Shared 13-gram after lowercasing and tokenizing with `[a-z0-9]+`.

| Benchmark | Test items | Exact-normalized source rows | 13-gram source rows |
|---|---:|---:|---:|
| HumanEval | {stats['benchmarks']['HumanEval']['test_items']} | {exact_h} | {gram_h} |
| MBPP (`full`, `test`, field `text`) | {stats['benchmarks']['MBPP']['test_items']} | {exact_m} | {gram_m} |

Any source row matching either criterion was removed before splitting. Complete
row-to-benchmark evidence is in `rejections.jsonl`. A row touching multiple
items or criteria is rejected once but retains every hit in that log.

## Filtering, deduplication, and split

| Stage / reason | Rows removed |
|---|---:|
| Empty output | {rejects['empty_output']} |
| Benchmark contamination (union) | {rejects['benchmark_contamination_union']} |
| Duplicate normalized `(instruction, input)` | {rejects['duplicate_normalized_pair']} |
| Train/test signature purge from train | {rejects['train_test_overlap_from_train']} |
| **Total removed** | **{rejects['total']}** |
| **Rejection rate** | **{rejection_rate:.4f}%** |

Rows are deduplicated on the tuple `(normalize_text(instruction),
normalize_text(input))`, where `normalize_text` is the same exact-normalization
function used by verification. The first source occurrence is retained.

The remaining rows are shuffled with Python's `random.Random(42)`. The test
size is `min(1000, round(0.05 * n))`; test receives the first shuffled indices.
Any normalized pair crossing train/test would be purged from **train**, never
test. The measured post-build intersection is {stats['post_build_checks']['train_test_normalized_pair_overlap']}.

| Split | Rows |
|---|---:|
| train | {splits['train']} |
| test | {splits['test']} |
| total | {splits['total']} |

## Lengths and diversity

Lengths below are lexical token counts using `[a-z0-9]+`.

| Field | Min | Median | Mean | P95 | Max |
|---|---:|---:|---:|---:|---:|
| User message | {lengths['user_tokens']['min']} | {lengths['user_tokens']['median']} | {lengths['user_tokens']['mean']} | {lengths['user_tokens']['p95']} | {lengths['user_tokens']['max']} |
| Assistant message | {lengths['assistant_tokens']['min']} | {lengths['assistant_tokens']['median']} | {lengths['assistant_tokens']['mean']} | {lengths['assistant_tokens']['p95']} | {lengths['assistant_tokens']['max']} |

The final dataset contains {stats['diversity']['unique_instruction_exact']}
exactly unique instructions and {stats['diversity']['unique_normalized_pairs']}
unique aggressively normalized `(instruction, input)` pairs. It preserves
{stats['diversity']['rows_with_nonempty_input']} rows with non-empty inputs.
No semantic-quality filter, language classifier, code execution, or model-based
judgment was applied; this release intentionally does not rewrite source data.

## Reproducibility and files

- Seed: `{SEED}`.
- Build script: `build.py`.
- Independent Hub verification script: `verify.py`.
- Machine-readable measurements: `stats.json`.
- Rejection evidence: `rejections.jsonl`.
- Validation report: `validation_report.json`.
- Source revision: `{SOURCE_REPO}@{SOURCE_REVISION}`.
- HumanEval revision: `{HUMANEVAL_REPO}@{HUMANEVAL_REVISION}`.
- MBPP revision: `{MBPP_REPO}@{MBPP_REVISION}`.

| File | SHA-256 |
|---|---|
| Source Parquet as downloaded | `{stats['source']['sha256']}` |
| `data/train.parquet` | `{hashes['data/train.parquet']['sha256']}` |
| `data/test.parquet` | `{hashes['data/test.parquet']['sha256']}` |
| `rejections.jsonl` | `{hashes['rejections.jsonl']['sha256']}` |

Run `python build.py` to rebuild locally or `python build.py --publish` to rebuild
and upload. Publication reads `HF_TOKEN` from the environment or from the
profile `.env`; the token is never written to an artifact.

## License and attribution

The dataset is released under **CC BY 4.0**, inherited from the Hugging Face
source dataset. It is a derivative: rows were mechanically reformatted,
filtered for empty outputs and benchmark contamination, deduplicated, and
seed-split. Attribute the original dataset as:

> Sahil Chaudhary, CodeAlpaca-20k, 2023,
> https://huggingface.co/datasets/sahil2801/CodeAlpaca-20k,
> revision `{SOURCE_REVISION}`, CC BY 4.0.

The upstream CodeAlpaca GitHub repository separately labels its code and data
under Apache-2.0, while the exact Hugging Face source used here is explicitly
CC BY 4.0. This derivative conservatively follows the source dataset's CC BY
4.0 license.

## Limitations

The original outputs were generated with `text-davinci-003`; this release does
not independently validate their correctness, security, language, or
executability. Decontamination is limited to exact normalized equality and
lexical 13-gram overlap against the pinned HumanEval and MBPP test prompts; it
does not prove absence of semantic paraphrases. The test split measures this
source distribution and is not a replacement for external code benchmarks.
