Overview

The independently generated synthetic translation corpus and the final forward/reverse SFT data. Includes the original held-out translation test split and the original train split without creating a new split.

Property	Value
Artifact	HexaBee · Bidirectional Translation
Scope	Phase 3 · pairs + final SFT
Released rows	1,023,992
Format	Sharded Parquet + metadata
Release	Audited historical artifacts
Model family	HexaBee-4B / Gemma 3

Quick start

from datasets import load_dataset

ds = load_dataset("Iman998/HexaBee-Bidirectional-Translation", "aligned_pairs", split="train", streaming=True)
print(next(iter(ds)))

Contents

aligned_pairs: 329,146 train and 36,572 test pairs. forward_sft and reverse_sft: 329,137 training rows each. Together the latter two configurations are the 658,274 final SFT examples. Pair rows and SFT rows are distinct views of overlapping content; their counts must not be interpreted as independent examples.

release_manifest.json lists distributed files, sizes, and SHA-256. release_stats.json records measured artifact metadata. Data files use bounded Parquet shards; original strings and empty outputs are preserved in historical exports.

Available configurations

Configuration	Splits	Rows
aligned_pairs	train, test	365,718
forward_sft	train	329,137
reverse_sft	train	329,137

Provenance

Native source generation metadata identifies DeepSeek-V3.1. Translation generation uses the service alias deepseek-chat, without an immutable backend revision for every call. The historical split was unseeded; these stored memberships are preserved. Nine train pairs were removed before reversal. Reverse examples swap aligned texts and do not constitute model-generated back-translation.

This release is part of HexaBee-4B, previously labeled PCT-4B in the local evaluation audit. Both names refer to the same final translator. Renaming does not imply retraining. This repository is an artifact release, not evidence of workshop acceptance or an official shared-task ranking.

Limitations

Historical exports may contain empty strings, imperfect generated text and instruction conflicts. Source row reuse is not independent evidence. See measured release statistics and the accompanying evaluation scope.

The complete adaptation recipe was evaluated; no matched ablation isolates the contribution of multilingual answering. Synthetic references and model-based judges limit interpretation. Long COMET inputs are truncated at the encoder limit. Use the independent evaluation repository for precise sample counts, parameters, all directions, and uncertainty estimates.

Each phase, checkpoint, prompt inventory, output archive and evaluation result has its own repository and card. Model cards identify the exact adapter base; dataset cards identify the unit of a released row. Historical row counts are not counts of unique source articles.
