The 6 Best LLM Tools To Run Models Locally

Running large language models (LLMs) locally is gaining traction among developers who prioritize data privacy and wish to avoid sending information to cloud-based AI model providers like DeepSeek and OpenAI. Several tools, such as LM Studio, Jan, Llamafile, GPT4ALL, Ollama, and LLaMa.cpp, enable users to run and test LLMs on their devices without internet connectivity, ensuring that data remains secure and private. These tools offer various features, including model customization, cross-platform support, and the ability to run without subscriptions or additional costs, making them appealing for both personal and commercial use. LM Studio, for example, offers a user-friendly interface for managing model parameters and supports multiple operating systems, while Jan provides an open-source alternative to ChatGPT with a focus on local execution. Llamafile simplifies AI integration by converting LLMs into executable files, and GPT4ALL emphasizes privacy and offline functionality. Ollama facilitates the creation of local chatbots without the need for external APIs, and LLaMa.cpp serves as a backend technology that supports significant LLM inferences across various hardware. These tools provide developers the flexibility to experiment with LLMs locally, offering significant benefits in contexts where internet connectivity is limited or where data privacy is a primary concern.
