I evaluated file, vector, graph and RL based memory frameworks

An agent that remembers across sessions can keep its memory as curated markdown files, as an auto-mined structured store, or as trained experience.

In plain words

This project evaluates different memory architectures for AI agents that need to retain information across sessions. It compares three approaches: curated markdown files, automatically-mined structured stores with graph linking, and trained experience embedded in model weights. The evaluation measures performance across fixed models, structured storage methods, and agentic benchmarks to determine which memory framework works best for persistent agent learning.

An agent that remembers across sessions can keep its memory as curated markdown files, as an auto-mined structured store, or as trained experience. I measured all of them: files against a structured store under one fixed model, a store-only head-to-head across the structured lineages, and an experience bank on the agentic benchmarks where the state of the art trains memory into the weights. Three side-by-side memory shapes: a file-based index of markdown lines, a structured store of embedded units linked by a graph, and trajectories of agent experience with one successful episode ringed. An agent that only remembers within one conversation is a stranger with excellent manners: it greets you…from pinglin.tw

  • 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…

    Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
