Building open Traditional-Chinese NLP resources — models & datasets — and the infrastructure, agents and products of an AI-native studio. Since 2020.
YuhuanStudio does AI & ML research and development, with a focus on Traditional-Chinese (繁體中文) natural-language processing for Mandarin speakers everywhere. Around that research we build the working stack of an AI-native studio — a model gateway, on-device inference, agents, and a design system.
🚧 Some of it is open here; a lot is still in progress and not yet open-sourced. This page grows as we release more.
The open core of the studio — models and datasets on 🤗 Hugging Face → yuhuanstudio, plus the tooling on GitHub.
- Yunmo — small language models pretrained from scratch for Traditional Chinese:
Yunmo-V1(0.2B),Yunmo_v0.1/Yunmo_v0(0.1B). 🤗 models - 15 Traditional-Chinese pretraining datasets — Wikipedia (
wikipedia-pretrain-zh-tw,wikipedia-image-zh-tw), forum (PTT-pretrain-zhtw), web (c4_pretrain_zhtw), news (OpenNewsArchive_pretrain_zhtw), dictionary (twdict_pretrain), reasoning (gsm8k_zhtw), document classification (TWDOCI), and more. 🤗 datasets - WikiZH_Dataset — the Chinese-Wikipedia
corpus toolkit behind those datasets: pretraining & multimodal set generation, Traditional↔Simplified
conversion, quality filtering, one unified CLI.
Python
| Project | What it is |
|---|---|
| YunUI | A quietly beautiful, versioned React 19 + Tailwind v4 design system — OKLCH design tokens, primitives, patterns and AI components in one package, already shipping in production. npm i @yuhuanowo/yunui → ui.yuhuanstudio.com |
| Yunshu | Fast, local, multimodal inference engine for Apple Silicon — OpenAI/Anthropic-compatible, with native streaming speech-to-speech via Qwen3-Omni. Text, vision, audio, image & embeddings on MLX. Python |
- Yunxin — a cross-generational LLM API gateway: 24+ providers behind one API key, across Chat Completions / Responses / Messages formats. Live at api.yuhuanstudio.com.
- More agents, apps and infra are in active development and not yet public — watch this space.
- AI-Friend (archived) — an early experiment: a local-LLM AI VTuber / companion with real-time TTS and VTube Studio avatar control. Kept as a development record.
