Local LLM (Large Language Model)
Local Large Language Model
A generative AI model that runs directly on your own computer or server
In Simple Terms
A local LLM is an AI that runs entirely on your own computer without needing an internet connection. Popular AI tools like ChatGPT typically borrow computing power from the developer's massive servers over the internet — but a local LLM handles all processing right on your own machine. Because no data is sent to external servers, local LLMs are widely used in enterprise development environments that handle confidential information, as well as in locations with unreliable internet connectivity.
Behind the Name
The name combines "Local" — meaning situated on or near the device itself — and "LLM," which stands for Large Language Model. Large Language Models are AI systems trained on vast amounts of text data. The "Local" part distinguishes these models from cloud-based AI services, signaling that all processing happens on your own hardware rather than on remote servers.
Take a Closer Look!
A local LLM refers to a setup where AI software is installed and run directly on your own computer or a server you manage yourself.
Most AI services people use today rely on computing infrastructure owned by third-party companies, accessed over the internet. A local LLM brings that entire process onto your own hardware.
The model uses your machine's processing power to generate text, answer questions, and perform other language tasks.
The two main advantages are data privacy and customizability.
Because no data is sent over the internet, you can feed sensitive or confidential documents to the AI without worrying about information leaking to external parties.
You can also fine-tune or modify publicly released models to suit your specific needs, and run them in environments without internet access.
Running a local LLM typically requires a capable GPU and sufficient RAM. Demanding tasks call for high-end hardware, but advances in the field have produced lightweight models that can run on everyday consumer computers.
Local LLMs are a popular choice for anyone who wants full control over how their AI behaves and what data it can access.
