<h2 id="english">🌸 About Us</h2>

We build datasets, train models, run evaluations, and publish benchmarks for **literary and niche-domain translation**. Light novels, visual novels, galgames, web fiction — the domains where generic Machine Translation collapses into polite nonsense. 

At **OpenSakura**, we believe in open science and reproducible results. Everything we do is done in public, with receipts.

### 🎯 What We Do

- 📚 **Datasets** — Curated, schema-validated, with documented lineage and licensing. High-quality parallel corpora designed specifically for our target domains.
- 🔬 **Experiments** — Fully reproducible training runs with pinned revisions, deterministic setups, and meticulously logged metrics.
- 📊 **Benchmarks** — Comprehensive LLM-as-a-judge pairwise evaluations, establishing Elo-style rankings for translation models.
- ⚔️ **Arena** — Blind A/B human evaluation platform to gather high-fidelity preference data for RLHF and DPO.

### 🌱 Origins

OpenSakura grew out of the [SakuraLLM](https://huggingface.co/SakuraLLM) community — the pioneering open-source project for Japanese-to-Chinese ACGN translation models. Members of that community came together to push the mission further: broader language pairs, rigorous reproducibility, public benchmarks, and a more open development process. We stand on their shoulders and are deeply grateful for the foundation they built.

OpenSakura 是一个专注于**特定领域大语言模型 (LLM) 翻译**的开源社区项目。我们致力于构建高质量数据集、训练专属模型、执行严格评测并发布权威基准——全面覆盖**轻小说、视觉小说 (Visual Novel)、Galgame、网络小说**等通用机器翻译极易“翻车”的垂直领域。

### 🎯 我们做什么

- 📚 **数据集** — 经过精心整理与严格校验，具备完整的来源追溯与明确的开源许可。
- 🔬 **实验** — 保证绝对可复现的训练流程，锁定数据集与模型版本，并记录完整的训练指标。
- 📊 **基准测试 (Benchmarks)** — 引入基于 LLM 作为裁判 (LLM-as-a-judge) 的成对评测机制，建立科学的 Elo 排名体系。
- ⚔️ **竞技场 (Arena)** — 开展盲评 A/B 人工评测，为后续的 RLHF 和 DPO 算法提供高质量的人类偏好数据。

### 🌱 社区起源

OpenSakura 脱胎于 [SakuraLLM](https://huggingface.co/SakuraLLM) 社区——那是日中 ACGN 翻译领域的开源先驱。怀揣着将这项事业推向更高峰的愿景，社区成员们再次集结：我们致力于**支持更丰富的语言对、贯彻更严格的可复现性标准、构建公开透明的基准评测，并推行更加开放的开发流程**。

我们站在前人的肩膀上，对 SakuraLLM 奠定的坚实基础致以最深的敬意与感谢。
