About
I'm Yuhuan, an undergraduate with a deep interest in artificial intelligence.
My work in AI runs from datasets, LLM base models, inference infrastructure and API gateways through to applications like AI agents and AI news. Outside that, I have shipped macOS applications, designed front-end websites, run Minecraft servers, and built Discord bots.
Rather than a polished demo that beats someone else's, or a product that is easy to monetise, I would rather build things that contribute to the community and applications that solve real problems.

Work
- YunAudioAn audio router for macOS with its own virtual device, and a signal path that can be proved bit-exact.
- YunNEWSA daily digest of what happened in AI, in Traditional Chinese, every item carrying its original source.
- YunAgentA general-purpose agent workbench. LLM, Plan and Agent modes share one durable runtime: events, checkpoints, pause/resume/replay, MCP tools.
- YunshuFast local multimodal (omni) inference engine for Apple Silicon — with native streaming speech-to-speech via Qwen3-Omni. Text, vision, audio, image & embeddings on MLX.
- YunUIA React 19 + Tailwind v4 design system that doesn't shout. Token-driven, three themes, framework-agnostic adapters — every detail quietly considered, none of it loud.
- Yunmo-NextA Chinese language model pretrained from scratch on a GQA + Kimi Delta Attention hybrid, grown layer by layer from 0.44B to 1.01B parameters with a native 32K context.
- YunxinA unified API gateway that aggregates 24+ LLM providers behind a single API supporting Chat Completions API, Responses API, and Messages API. One API key, every model.
- YunmoA digital being that keeps existing — with its own sense of time, its own emotional boundaries, and an inner life that depends on no one. Built on LinOSS and an 8-dimensional emotion vector, so that computation produces something that deserves to be called company.
- WikiZH_DatasetA Chinese Wikipedia corpus toolkit for pretraining and multimodal datasets: one parse yields plain text, interleaved image-text, and image-caption pairs.
- Yunmo V1A Traditional Chinese small language model pretrained from scratch on the minimind architecture, v0 through v1.
- AI-FriendA locally-run AI character built on LangChain, Ollama and ChatTTS, with an optional VTube Studio link to drive an avatar.
- GuizhongA feature-rich Discord bot with music, AI integration, lottery, and more.
