# Tuned Tensor Customer Support v1

An unsplit chat JSONL derivative prepared by Tuned Tensor from [bitext/Bitext-customer-support-llm-chatbot-training-dataset](https://huggingface.co/datasets/bitext/Bitext-customer-support-llm-chatbot-training-dataset/tree/430d1a89bd93bd1fa23c16f29dd53e73f0087443), originally published by Bitext. Released 2026-10-16. This is a format-normalized, conservatively filtered collection; it is not an independently human-audited quality benchmark or an endorsement by the upstream publisher.

## Data and split policy

- Records: **23,087**; UTF-8 JSONL file: `data.jsonl` (30,763,489 bytes).
- SHA-256: `8011cf888aaedb18c01424f4d003f00bad81985398b1a57c56bd2dce677ff35d`.
- Exactly one Hugging Face collection named **`unsplit`**. No train/validation/test partitions are assigned by Tuned Tensor.
- Original split labels remain in `metadata.origins[].original_split`. Published benchmark holdouts must be respected if reporting results against that benchmark. Randomly repartitioning combined source splits does not preserve the original benchmark evaluation protocol.

## Structure

Each row has `id`, `group_id`, `messages`, and `metadata`. `messages` contains one user request followed by one assistant answer. No system prompt is baked into the master; supply the instructions appropriate to your task when constructing training inputs.

`metadata` retains domain, category, license, quality-check flags, and an `origins` list containing the source repository, pinned revision, source file and source row. Exact-answer duplicates merge origin records. Empty quality objects in the initial local preparation were replaced with `structure_validated: true` where necessary for Hub Parquet compatibility; this records the existing structural checks, not semantic quality. Extra task-specific metadata may be present. Source IDs are retained where supplied; derived IDs are deterministic hashes.

## Load without assigning training splits

```python
from datasets import load_dataset
rows = load_dataset("tunedtensor/customer-support-v1", split="unsplit", streaming=True)
example = next(iter(rows))
```

Download `data.jsonl` directly for local tools. Choose train/validation/test ratios, grouping, stratification and seed separately for each experiment. Keep the original master unchanged.

## Conversion and filtering

Empty, NUL-containing and oversized prompt/answer pairs (>100,000 combined UTF-8 bytes) are rejected. Prompt identity uses NFKC normalization, collapsed whitespace and case-insensitive comparison. Identical-answer duplicates merge origins; all records for prompts with differing answers are excluded conservatively. Different answers can both be valid, so exclusion does not prove a source row was incorrect. This is exact normalized matching, not semantic deduplication.

Templated support responses retain their placeholders. They are not verified company policies. The 27 source intents are retained in `metadata.category`. This derivative remains licensed under CDLA-Sharing-1.0.

| Processing counter | Rows |
|---|---:|
| `source_rows` | 26,872 |
| `conflicting_rows` | 3,785 |
| `kept_rows` | 23,087 |

The counters describe this recipe's processing decisions; `kept_rows` is the released record count. See `manifest.json` for source file checksums and recipe hash. `validation.json` records full-output structural, ID uniqueness, prompt uniqueness, provenance and checksum checks.

## Limitations

Validation does not establish semantic answer accuracy, absence of personal information, absence of near duplicates, or freedom from benchmark contamination. Downloaded code/tests and SQL were not executed. Review and evaluate the data for your own task; source licenses and notices continue to apply. We have not measured model-quality gains from fine-tuning this release.

## Source, license, and changes

Original data: Bitext, [bitext/Bitext-customer-support-llm-chatbot-training-dataset](https://huggingface.co/datasets/bitext/Bitext-customer-support-llm-chatbot-training-dataset/tree/430d1a89bd93bd1fa23c16f29dd53e73f0087443), revision `430d1a89bd93bd1fa23c16f29dd53e73f0087443`. Tuned Tensor added the unified chat structure, IDs, provenance, grouping metadata and the filtering described above. The upstream dataset card is preserved as `UPSTREAM-CARD.txt`.

This derivative is distributed under **CDLA-Sharing-1.0**. Retain the license text in `LICENSE.txt`, source attribution, and change notices in `ATTRIBUTION.json` when redistributing. Any additional original notice is retained in `UPSTREAM-LICENSE.txt` where supplied. No affiliation with or endorsement by Bitext is implied.

## Reproduce

`convert.py` is the exact recipe whose SHA-256 appears in the manifest. `download.py` pins the public source repositories, including the original BANKING77 CSV commit. These scripts operate relative to their own directory, using `sources/` and `prepared/` folders; the download script covers all four initial collections. Run in a fresh working directory:

```sh
uv venv --python 3.13 .venv
uv pip sync --python .venv/bin/python requirements.lock
.venv/bin/python download.py
.venv/bin/python convert.py customer-support
```

No source dataset loading scripts are executed. Python 3.13.14 was used for this release. The master output checksum is provided above so reproduced outputs can be compared.
