Zebrapuzzles.com – Daily Logic Puzzles
Hi all, I've always been fascinated by logic puzzles and, over the past 15 years, I've published around 300 zebra puzzles, mostly in Portuguese. Now, using LLMs, I've managed to automate the creation of these puzzles, leading to the birth of ZebraPuzzles.com. There are around 80 different themes that the generator uses to transform a raw puzzle into a thematic one. For instance, the LLM translates this clue: >The girl Shirt=Pink is next to the girl Age=11 to >The girl who wears a Pink shirt is next to the 11-year-old girl. The website offers five new logic puzzles daily, designed to…
In plain words
Zebrapuzzles.com offers five new logic puzzles daily, automatically generated using large language models. The puzzles feature 80 different thematic variations that transform raw logic problems into more natural language scenarios. Originally published manually in Portuguese over 15 years, the site now uses AI to create varied constraint-satisfaction puzzles that challenge problem-solving skills. Players can track progress interactively with JavaScript or solve manually by marking clues.

Hi all, I've always been fascinated by logic puzzles and, over the past 15 years, I've published around 300 zebra puzzles, mostly in Portuguese. Now, using LLMs, I've managed to automate the creation of these puzzles, leading to the birth of ZebraPuzzles.com.

The website offers five new logic puzzles daily, designed to challenge and engage your problem-solving skills. The site requires JavaScript to track your progress interactively, but for those without JavaScript enabled, you can still enjoy the puzzles by marking off clues manually. While classic Logic Puzzles requires a grid, the puzzles we generate do not: they're solvable using only basic logic and pen/paper. I'm eager to hear your thoughts and feedback. Are the puzzles challenging enough?

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…
