Tuned Tensor Customer Support v1

An unsplit chat JSONL derivative prepared by Tuned Tensor from bitext/Bitext-customer-support-llm-chatbot-training-dataset, 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

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, 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:

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.
