Local-first AI for language learning.
Byte-level interfaces for language models.

做本地优先的语言学习 AI,
研究字节级语言模型接口。

中国矿业大学本科一年级,CUMT Alethic Insight 实验室核心成员。 一边造能在自己机器上跑起来的外语学习系统,一边追问:分词器真的是必须的么?

First-year undergraduate at China University of Mining and Technology, core member of CUMT Alethic Insight Lab. I build foreign-language learning systems that run on your own machine — and keep asking whether tokenizers are really necessary.

Position / 关于

Position / About

语言与模型的交界处,是我最常驻的地方。

Where language meets models is where I spend most of my time.

应用侧,我做本地优先的外语学习 AI:词汇、作文批改、实时语音对话、课堂实时助教,敏感数据默认留在本机。 研究侧,我维护 FLUED——一个关于无分词器字节到潜变量接口的公开研究档案,版本化实验、消融和证据注册表全部留档。

On the application side, I build local-first AI for foreign-language learning — vocabulary, essay grading, real-time voice dialogue, and in-class teaching assistants, with sensitive data staying on your own machine by default. On the research side, I maintain FLUED, a public research archive on tokenizer-free byte-to-latent interfaces, with versioned experiments, ablations, and an honest evidence registry.

我在做的四条线

Four lines of work

01

AI × Language Learning

全栈本地优先的外语学习平台:智能词汇、六维作文批改、ASR→LLM→TTS 实时语音、课堂实时助教,端云协同推理。

A full-stack, local-first platform for foreign-language learning: smart vocabulary, six-dimension essay grading, real-time ASR→LLM→TTS voice dialogue, and an in-class assistant, with end-cloud collaborative inference.

02

Tokenizer-free Interfaces

FLUED:原始字节流能否在进入主干模型之前,被翻译为紧凑、可解码、可逆的潜变量表示?主张什么、不主张什么,全部写在证据注册表里。

FLUED: can a raw byte stream be translated into a compact, decoder-compatible, reversible latent representation before the backbone? What we claim — and what we don't — is all written into the evidence registry.

03

Agents & Research Tools

Open WebUI 工具调用生态:把科研调研沉淀为图、树、时间线的 ResearchMap;考试期复习桌面系统 ExamPilot。

An Open WebUI tool-calling ecosystem: ResearchMap, which distils research surveys into graphs, trees, and timelines; and ExamPilot, a minimalist exam-season desktop companion.

04

Earlier Engineering

早期工程作品:覆盖建筑、交通、机房、生活的 AI 节能系统(CV / RL / GraphRAG),以及建筑模型到 Three.js 的精确转换工具链。

Earlier engineering work: an AI energy-saving system spanning buildings, traffic, labs, and daily life (CV / RL / GraphRAG), plus an exact building-model to Three.js conversion toolchain.

How I work

Local-first

敏感数据默认留在本机,云端只是可选项而非前提。

Sensitive data stays on your machine by default; the cloud is an option, never a prerequisite.

Reproduce

实验记录、数据来源与判词全部留档,证据先于结论。

Experiment logs, data sources, and verdicts are all archived — evidence before conclusions.

Disclose

公开 AI 辅助的范围与验证方式,不接受盲目提交,包括我自己。

AI assistance is disclosed with its scope and verification — no blind submissions, including my own.

Handoff

文档、接口与维护边界预先写明,让别人接得住。

Docs, interfaces, and maintenance boundaries are written upfront, so others can pick the work up.
