Hypersplit – Like Infinite Craft but in reverse
Hypersplit is like Neal's Infinite Craft but turned upside down. Instead of crafting your way up from the four elements, you start big and go small, down to quarks. It's using GPT-4 to split the words, but a big difference from Infinite Craft is that I can precalculate the possible paths since they are limited (sooner or later you hit a quark or a loop). This means that I can ship it with the whole dictionary locally instead of hitting an LLM every split. While it started with just the splitting, I quickly got the urge to split things faster... which turned the app into the incremental…
In plain words
Hypersplit is a reverse version of Infinite Craft where players start with large words and repeatedly split them into smaller components, eventually reaching fundamental "quarks." Using GPT-4 to determine splits, the game pre-calculates all possible decomposition paths and stores them locally, eliminating the need for constant API calls. The app evolved into an incremental clicker where players can accelerate splitting speed. Built entirely with emojis and CSS, it offers a text-based experience with chain reactions and progression mechanics.

Hypersplit is like Neal's Infinite Craft but turned upside down. Instead of crafting your way up from the four elements, you start big and go small, down to quarks.

This means that I can ship it with the whole dictionary locally instead of hitting an LLM every split. While it started with just the splitting, I quickly got the urge to split things faster... which turned the app into the incremental clicker it is now. It's pretty short and starts lagging a lot once things get crazy with a lot of chain reactions (turning off Effects helps a bit), but I plan to focus on optimizations next. I also wanted to try and build something without any graphical assets. The whole game is all just emojis and CSS. A big gotcha is that you can't rely on emojis looking the same on different platforms (for example, on Windows, the explosions are misaligned).

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…
