I'm Panmauk, CEO of PANMOX — a small independent open source software project.</p> <p>Today I want to share something we've been quietly building: NeuralXP.</p> <h2> What is NeuralXP? </h2> <p>NeuralXP is a real, working offline language model that runs as a native Windows XP application. Not a joke. Not a demo. A fully functional LLM you can download, install, and talk to — on hardware from 2001.</p> <h2> Why does this exist? </h2> <p>Most AI tools today require:</p> <ul> <li>A monthly subscription</li> <li>A modern GPU</li> <li>An internet connection</li> <li>An account with some company</li> </ul> <p>We think that's wrong. AI should be accessible to everyone, including people running old machines. If your computer can run Windows XP, it can run NeuralXP.</p> <h2> How does it work technically? </h2> <p>Under the hood:</p> <ul> <li>Model: Qwen2.5-0.5B (a genuinely capable small LLM)</li> <li>Runtime: llama.cpp, compiled for Windows XP compatibility</li> <li>UI: A native Win32 application — real .exe, real installer, real Windows UI</li> <li>No Electron, no browser, no 800MB Chromium overhead</li> </ul> <p>Minimum specs:</p> <ul> <li>Windows XP SP2 or later</li> <li>512MB RAM</li> <li>Single-core CPU (500MHz+)</li> <li>500MB disk space</li> <li>No GPU required</li> </ul> <h2> What does it actually do? </h2> <p>It's a local chat interface. You type, it responds. Your prompts never leave the machine. No telemetry, no accounts, no network calls at all. It boots fast, runs light, and works completely air-gapped.</p> <h2> The philosophy </h2> <p>At PANMOX we build software that lasts. The version you install today should still work in 2046, on the same hardware, without asking permission from a server somewhere. The cloud took AI and put it behind subscriptions and logins. We're giving it back.</p> <h2> It's completely free and open source </h2> <p>GPL v3. Full source on GitHub. No paywalls, no premium tiers, no "pro" version. Free forever.</p> <p>Check it out: <a href="https://panmox.org/neuralxp" rel="noopener noreferrer">https://panmox.org/neuralxp</a></p> <p>Would love to hear your thoughts — especially from anyone who still has old hardware lying around!</p> ai opensource
