Pure Rust implementation of a minimal Generative Pretrained Transformer - keyvank/femtoGPT
FemtoGPT – Pure Rust implementation of a GPT language model launched on June 4, 2023 with 19 votes, #1,570 of 4,655 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 3 years on.
In plain words
FemtoGPT is a lightweight language model implementation written entirely in Rust. It allows developers to build and run GPT-style models with a minimal, efficient codebase. The project targets programmers interested in understanding language model architecture or deploying models in performance-critical environments where Rust's speed and memory safety are advantageous. Its pure-Rust approach distinguishes it from implementations relying on external dependencies or other languages.

LocalGPT – A local-first AI assistant in Rust with persistent memoryFeb 2026 · github.com · ▲331I built LocalGPT over 4 nights as a Rust reimagining of the OpenClaw assistant pattern (markdown-based persistent memory, autonomous heartbeat tasks, skills system). It compiles to a single ~27MB binary — no Node.js, Docker, or Python required. Key features: - Persistent memory via markdown files (MEMORY, HEARTBEAT, SOUL markdown files) — compatible with OpenClaw's format - Full-text search (SQLite FTS5) + semantic search (local embeddings, no API key needed) - Autonomous heartbeat runner that checks tasks on a configurable interval - CLI + web interface + desktop GUI - Multi-provider:…

Heya HN, I've been working on a reddit-like platform as my primary side project for the last few years. Doing a (very) soft launch today, mainly because I want to use it to encourage discussion of alternatives. How non.io works: 1. Free to browse, paid to interact. 2. Minimum subscription is $2 (though you can choose more). I take $1 to run the servers, everything left gets split evenly between everything you upvote that month. It's a simple model, but I hope it's a better one than the freemium model we've been relying on for the last few years. Fundamentally I feel like any ad-supported…
