Kioku Lite
Knowledge Graph memory for AI agents. Single SQLite file.
What it does
Most AI agents forget everything between sessions. Existing memory tools store flat text or vectors — they can't answer "why was I stressed last month?" because they don't track relationships. Kioku Lite adds a Knowledge Graph on top of keyword and semantic search. Three search signals (BM25 + Vector + KG) fused via Reciprocal Rank Fusion — all in a single SQLite file. Zero Docker. Zero cloud. Fully offline. Just pip install. Works with Claude Code, Cursor, Windsurf, and OpenClaw.

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…
