Airpoint Open SDK
Touchless controls for any application
What it does
Airpoint is a tiny open source SDK that adds touchless hand control to any web app with just a webcam, no extra hardware. npm install @airpoint/sdk, point it at a tag, and your users can move a cursor, click, and scroll with their hand. Powered by AirMouse, our in-house ML model (97.7% accuracy, ~1ms inference, runs entirely in the browser).

Hey Everyone! I wanted to show my passion project I made a few years back and recently turned into a web app. Airdraw is an app that takes in your hand gestures and converts it into real time drawing capabilities. There are tons of stuff I want to build with this, but most importantly just put it out into the world! Hope you all enjoy :) Tested on my MacOS with Chrome, Safari, and FF I included a link to the original GH project I wrote here - https://github.com/arefmalek/airdraw and a link to the blog where I explained how I made it here -…

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…
