Prompts are picked from the public LLM Arena dataset and handed to Claude, GPT, Grok, Kimi and others for a single shot, with no manual edits. Tasks include a lava-lamp physics sim, a Windows 98 Paint clone, a MacBook Air comparison page, a rotating kebab and a flight through Van Gogh's Starry Night. Every entry opens full screen, and the arrow keys flip between models.

Each prompt is reusable: a steampunk clockmaker's workshop, a cherry-blossom railway stop, a tidal research station. Every build records the model and coding agent behind it, so a prompt page can run all of its entries side by side. Scenes are self-contained single-file HTML, sandboxed twice (an opaque-origin iframe plus CSP), and are added through an authenticated API and a skill without rebuilding the image.

A Go daemon on the dev machine and the browser both dial out to a self-hosted relay; pairing takes one 6-digit code. The web UI has a real PTY terminal, a file browser, Git diffs and local port forwarding, talks directly to ACP agents such as Devin and cursor-agent, and can hand out temporary read-only links when you want to ask someone for help.

Upload one or more receipt photos and a vision model reads the items, unit prices and totals. Receipts in other languages get a Chinese translation alongside, and included tax, added tax and discounts are reconciled arithmetically so everyone's shares add up to exactly what was paid. Bills and photos live only in the browser's IndexedDB; the server keeps no user data.

It reads the response of the send-message API to tell whether a message is visible only to you. Swallowed messages turn red in the chat list with a "banned" badge; a floating panel on the stream page covers the current room, and the toolbar popup gathers every room with filters, search and CSV import and export. Records sync across computers with your Chrome account. The sync area is packed deterministically from newest to oldest, so devices converge on one copy instead of overwriting each other. The only permission left is storage.

v0.2 goes beyond a read-only Apple Health summary (sleep, HRV, resting heart rate, steps, active energy, exercise minutes) and adds eating and training. Snap a meal and AI breaks it into items with nutrition; tick items and drag a slider for how much you actually ate. Packaged food is read straight from the nutrition label, with kJ converted to kcal. Plan workouts by week, log sets and weights, and review history. The raised button in the tab bar is press-to-talk: say "a bowl of beef noodles for lunch" or "500 ml of water" and it's logged. Meals, water, weight and goals stay on device, export to JSON, and can optionally be written back to Apple Health; only photo recognition and voice commands go to my own server, and only after you allow it.

Recording something and finding that one sentence later should both take two taps or less. The app opens on a big red record button, and you can also start recording from the Lock Screen, Control Center, the Action Button or Apple Watch without unlocking; a Live Activity lets you pause and stop. Recordings stay on device and anything over 30 seconds is transcribed automatically, either fully on iPhone with no upload and no account, or in the cloud via ElevenLabs Scribe with speaker diarization after Sign in with Apple. Transcripts are timestamped subtitles: tap any line to play from there, the current line follows playback, with speed control, ±15 s and speaker renaming. Organize recordings into projects, search titles and full transcripts, and sync across devices with iCloud.

Paste a link or some text, or upload a document. An LLM distills it into a structured summary, which is then laid out as a long read with sections, data cards and pull quotes, optionally translated into Chinese. A companion Chrome extension generates one from any article or Bilibili video page in one click.

A pixel engine, a general character system, YAML or Python scripts and chiptune music in one framework. Every frame is a pure function of time and renders in parallel across processes, so an 8-core machine turns out a 33-second short in 15 seconds. It can also turn the subject of a video into a pixel character. The framework was extracted and generalized from a 93-second MIT-licensed animation.

Every server runs a small Python agent that reads IPMI inlet temperature, GPUs, disk SMART data and NIC counters; the Next.js server polls them and writes to SQLite. The UI is styled like an industrial HMI and fits a single 1920×1080 screen. Sensors that cannot be read show "—" rather than 0, and alert thresholds can be changed at runtime.

It holds handy tools such as an LLM API playground, Anthropic and Gemini API testers, a JWT decoder and a timestamp converter, plus a pixel Mario remake and Flappy Bird. Snippets can be pinned and previewed, and any single one can be shared with anyone. The backend is wired to an LLM, so one sentence is enough to create or rewrite a snippet.

Built for two or three people polishing one deck together. opencode runs in a container as the agent engine; you can paste screenshots, upload assets, import HTML or PPTX, and export HTML, ZIP, PDF or PPTX. Sign-in is a shared password, and the model provider can be switched at will.

Personal use · not publicRequests are load-balanced across several Modal accounts. Requests that carry a session id stick to one account to keep the prefix cache warm, and failures switch over automatically with a cool-down. /v1/messages is translated to chat completions and back, with reasoning mapped to thinking blocks, so Claude Code plugs straight in. All traffic can also be mirrored to Langfuse.

A small Go service: for each chat completions request it runs the matching agent CLI in one-shot mode and returns the result in OpenAI format. /v1/models lists only the CLIs that are actually installed, a colon in the model name passes an inner model through, and any client or SDK that accepts a base URL works out of the box.

At the end of each turn a Stop hook asks a separate evaluator to check the condition. If it isn't met, the stop is blocked and the evaluator's reasoning becomes the next instruction; once it is met, the goal clears itself. A Python installer adds it to Devin's global config, and it works on Windows too.

Models and tasks are organized by dimension (code quality, reasoning, frontend generation, summarization and more) and scored by an LLM judge, a script, or both. The results page previews HTML output in a sandbox, takes star ratings and notes, and compares different models' answers to the same task side by side.

A FastAPI job API wraps it: upload an image, get a job id, and the model is built asynchronously, with orbit videos and depth maps rendered on CUDA machines. There are CPU and CUDA images, Bearer-token auth, and jobs and files tracked in SQLite.

About
More than classic software engineering, I care about fitting AI into real-world problems. From large language models, AI agents and workflow orchestration to computer vision, NeRF, digital humans, speech-driven animation and real-time audio and video, I like to understand how things work first, then turn research into products people can actually use.
I'm used to carrying a project end to end on my own: choosing the stack, designing the architecture, writing the code, then deploying and running it. I'm at home with Docker, Linux and cloud servers. This site and most of the projects above run on machines I look after, and I enjoy tinkering with and polishing my own dev setup.
Beyond the tech, I care just as much about product design, user experience and human–computer interaction. I love trying new tools and new ways of working with AI, and I think a lot about how AI will change the way software gets written. Lately I've been building things around health tracking, knowledge processing and AI tooling.
I believe technology is worth more than the problems it solves: it's about opening up new possibilities.
For me, programming isn't just a job. It's a way to explore the world, express ideas and make things.
