ChartHN – Hacker News' daily top 10, but in diagrams

For those who are interested in ChartHN's tech stack, here's a brief list: - HTML to markdown: Jina AI Reader - Markdown to Graphviz DOT: LLMs - Graphviz DOT to SVG: Viz.js - Data Storage: TSV files - Document updating: GitHub Actions - Frontend: HTML + CSS + Vanilla JS There are also side tools linked at the bottom of the ChartHN page: - a web tool to convert any page to a diagram - a visual benchmark to compare the performance of LLMs in generating Graphviz DOT data To fit Graphviz DOT data within a TSV file and reduce file size, I have also developed dot-minify…

In the maker’s words, at launch

For those who are interested in ChartHN's tech stack, here's a brief list: - HTML to markdown: Jina AI Reader - Markdown to Graphviz DOT: LLMs - Graphviz DOT to SVG: Viz.js - Data Storage: TSV files - Document updating: GitHub Actions - Frontend: HTML + CSS + Vanilla JS There are also side tools linked at the bottom of the ChartHN page: - a web tool to convert any page to a diagram - a visual benchmark to compare the performance of LLMs in generating Graphviz DOT data To fit Graphviz DOT data within a TSV file and reduce file size, I have also developed dot-minify (https://github.com/cxumol/dot-minify) as a sub-project. This is likely to be the world's first tool to minify Graphviz dot format data, according to my research.

  • 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…
