About
Browser-based chat UI for the TinySwallow-1.5B language model — runs fully on-device with no API calls.
What it does
A compact Japanese chat demonstration with guided prompts, streamed replies, Markdown rendering, conversation reset, and visible model-loading progress. The conversation remains in the page’s memory, while a WebGPU-backed runtime performs generation.
Why it's ranked here
Worth trying for its unusually direct path from static web assets to private local inference. It exposes model loading and token streaming clearly, but remains a research prototype with narrow deployment guidance and several implementation rough edges.
What's good
Setup requires only cloning the project and serving its static assets over HTTP. The interface reports download progress, streams partial answers, handles Japanese text composition, offers starter prompts, and supports resetting a conversation without reloading the page.
Tradeoffs
The initial model fetch requires network access, and fully offline startup needs a separate repository containing model files. The project explicitly rejects commercial and mission-critical use. Messages are parsed as Markdown and inserted into page HTML without any sanitizer shown. Error handling and keyboard event wiring also contain concrete defects.
How to use it well
Use it for research demonstrations, private experimentation, or learning how local web inference feels with a small Japanese model. Serve it locally, let the model download once, then test prompts offline. Choose another system for production guarantees, commercial deployment, server APIs, or mission-critical work.
Technical notes+
README.md documents a static HTTP-server workflow and directs offline-first users to a separate repository. index.js imports @mlc-ai/web-llm@0.2.48 from esm.run, configures a Hugging Face MLC model plus a WebGPU WASM library, and streams chat completions with fixed sampling penalties. It parses user and model text through marked.parse before assigning innerHTML, with no sanitizer visible. The textarea receives two keydown listeners, so the second listener defeats the first listener’s Shift+Enter behavior. The initialization catch block references button, downloadStatus, and downloadProgress outside their try block scope, which can break recovery after model-loading errors. index.html also loads Marked and Google Fonts from external hosts. docs/iphone.md describes a separate LLMFarm workflow using GGUF model files.
