HAND DUEL
Beat the AI at Rock Paper Scissors
What it does
Hand Duel uses your webcam to read your real hand gestures in real time. No buttons, no tapping — just hold up ✊ Rock, 🖐 Paper, or ✌️ Scissors and the AI reads your move instantly. 3... 2... 1... SHOOT! — then you both reveal at the same time.

I was curious to see how some of the latest models behaved and played no limit texas holdem. I built this website which allows you to: Spectate: Watch different models play against each other. Play: Create your own table and play hands against the agents directly.

I built this game to test out the MediaPipe hand-tracking API. Play brick breaker using your webcam + hand movement -- levels get progressively harder with faster speed / smaller paddle. All processing is done in real-time within your browser. This project is built using javascript, html canvas, and mediapipe hand tracking. This game is free and open source, offered under an MIT license. Github repo: https://github.com/collidingScopes/manual-brick-breaker Hope it's fun for you -- would love to hear feedback and suggestions for improvement.

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
