What is usb-ai-agent?

This project packages a portable AI system that runs entirely from a USB drive or external SSD. The idea is simple: plug the drive into any Windows or Linux computer, run one script, and you have a fully functional AI assistant that leaves no traces on the host machine. It builds on an earlier project called USB-Uncensored-LLM, which only offered a chat interface. This version adds something more ambitious, an autonomous agent that can take actions rather than just answer questions. The agent comes with 13 built-in tools that the AI model decides how to use on its own. These tools fall into several categories. For searching, it can query the web through DuckDuckGo, fetch and read webpages, and perform multi-step research by searching, downloading, and synthesizing information from multiple sources. For OSINT work, which means gathering publicly available information, it can check which websites an email address is registered on, search for a username across over 600 platforms, and scan 15 social networks at once. It can also read and write files, list directory contents, execute shell commands, run Python code, and save information to persistent memory that survives across sessions. The project ships with five preconfigured AI models ranging from 1.7 GB to 7.5 GB in size, totaling about 25 GB. These are "uncensored" models, meaning they have fewer built-in restrictions on what they will discuss. You need a USB 3.0 drive or SSD with at least 30 GB of free space and a computer with 8 GB of RAM minimum, or 16 GB recommended for the larger models. Everything runs offline after the initial download, with no accounts, no telemetry, and no tracking. Chat history saves only to the USB drive itself. The repo also includes three standalone Android apps, an AI companion called Blu, an improved companion called ZENO, and an AI-powered flight search app.
