How to set up a local AI chatbot on your computer

Large language models (LLMs) like those powering ChatGPT and Gemini are reshaping industries, offering capabilities in coding, writing, and web searches. Running these models locally on personal computers provides offline access and enhanced privacy, as data isn't sent to the cloud. Free LLMs from companies like Meta and Google are available for download, though they may lack the speed and sophistication of paid versions. Setting up a local LLM requires sufficient RAM, ideally 8 GB or more, and a dedicated GPU for optimal performance. Software like LM Studio Bionic, vLLM, and Llama.cpp are popular choices for managing these models. Users can select from a vast array of models on platforms like Hugging Face, which hosts over 3 million options. The setup process involves choosing a model, configuring settings, and managing files through the software interface. For Windows users, LM Studio Bionic is recommended for its ease of use and compatibility with various models.
