Fine-tuning Qwen3-8B on HydroBench

This repository provides scripts and data format definitions for fine-tuning Qwen3-8B on the HydroBench hydrogen-energy Q&A benchmark.

HydroBench is a bilingual (Chinese/English) domain dataset focusing on hydrogen production, storage, transport, fuel cells, safety, systems, and AI. It is designed for:

• Teaching / exam question answering
• Domain-specific assistant training
• Evaluation of LLMs on hydrogen energy literacy

1. Dataset Overview

HydroBench is organized as bilingual Q&A pairs, each with metadata describing its module and subtopic.

Each example has (at least) the following fields:

• id: unique identifier, e.g. A-ELC-04
• module: high-level module (A–E)
• subtopic: submodule shorthand, e.g. ELC
• question_zh, question_en: question in Chinese / English
• answer_zh, answer_en: reference answer in Chinese / English
• (optional) other fields such as difficulty, source, etc., depending on your version
