  Vidformer – Drop-In Acceleration for Cv2 Video Annotation Scripts2025 · github.com · ▲25

  Hi HN, this is a project I've been working on as part of my PhD. Vidformer is a system that makes video annotation or transformation scripts practically instant. Traditional scripts that render full videos can take minutes—Vidformer speeds this up by optimizing execution and using on-demand rendering, so results appear immediately instead of waiting for entire videos to render. It works as a drop-in replacement for OpenCV's cv2, meaning most scripts can adopt it by simply changing "import cv2" to "import vidformer.cv2 as cv2"—no need to rewrite code or sacrifice flexibility. Vidformer is…

  I trained a 125M model to autocomplete piano on-device▲598

  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.

  Needle2: 14MB agentic LLM for phones, wearables, smart home and robots▲537

  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…
