Show HN: MNIST64 – 99.5% accuracy MNIST BNN on a stock Commodore 64

I built an 8-bit binarized convolutional neural network that recognizes handwritten digits on C64 with state-of-the-art accuracy. I also designed a cascade model to get interactive response, and implemented everything with self-modifying cycle optimized 6502 assembly - resulting 0.653s average infer

Show HN: CUA-S1 – A System One Model for Computer Use

Hello HN! We're Dillon and Francesco from Cua. We were wondering how many computer use tasks actually need a full general purpose LLM (e.g. gpt-6-astra, claude-opus-5 etc.) to think through all their decisions and steps. Some tasks require thinking about a plan, exploring different paths, recovering

Show HN: I created an open source locally usable full fledged AI platform

hi to all the readers this post is for my recent opensource project called ENZO now answering what is enzo so enzo is an opensource platform where i clubbed all the free available api for anyone use under one hood with more than 2000 models available to use for chatting coding researching and much m

I built a paged LLM inference engine for Apple Silicon and cut attention memory by 128x

I’ve been building PagedServe , an experimental open-source LLM inference runtime for Apple Silicon The problem I wanted to explore was KV-cache fragmentation Most simple inference implementations allocate contiguous memory or reconstruct scattered KV blocks before attention At a

Show HN: Seal – Letters and passwords that open for your family after you die

I'm a CS undergrad who has developed an interest in hardware keys ever since I used them for a school project a few years ago. I made a little chat app that only allows users to chat if they registered a key, nothing else. The backstory of how I came to work on Seal (this project
