USB-Uncensored-LLM

USB-Uncensored-LLM is a local-AI tool - The ultimate zero-install, portable local AI environment. Run high-quality, uncensored LLMs (Gemma, Qwen, NemoMix) directly from any USB drive or SSD. Fully air-gapped, cross-platform (Win/Mac/Linux), and privacy-first with persistent chat history.

Overview

USB-Uncensored-LLM is a fully air-gapped, zero-dependency, plug-and-play Local AI environment designed to run seamlessly from your local hard drive or a portable USB/SSD. It bypasses complex installations natively executing large language models directly on your hardware with no internet required.

With a unified architecture, you can initialize your AI models once and choose to keep them on your system or carry them with you across Windows, macOS, and Linux PCs.

• Zero Dependency Setup: Ships with portable Python and isolated engine binaries. No system permissions, registry edits, or package managers required. * Cross-Platform Interoperability: Uses a intelligent 'Shared' volume system — download your 5GB+ AI models once, and use them natively on Windows, macOS, and Linux without duplication. * Censorship Free: Integrates cutting-edge ablative and heretic fine-tuned models for completely unfiltered interactions. * Network Proxied UI: The custom Python HTTP server instantly serves a blazing-fast dark mode UI. You can access the AI from your phone or tablet on the same WiFi network without complex CORS configuration. * Hardware Accelerated: Uses a custom-compiled Ollama engine under the hood, natively capitalizing on AVX CPU instructions, NVIDIA CUDA, or Apple Metal GPU accelerators dynamically when plugged into different host machines.

USB-Uncensored-LLM is open-source, written primarily in HTML, with 1,452 GitHub stars under the Open Source license. It was last updated on 2026-06-06.
