Open-source / open-weight model
오픈소스 모델
An AI model released so that anyone can download it, run it on their own computer and modify it.
Overview
A service like ChatGPT works by renting a model that sits on the company's servers. An open-source model is released as the model itself (the trained parameters), so you can download it and run it directly on your own computer or your company's servers.
Meta's Llama, Alibaba's Qwen, DeepSeek and Mistral are among those releasing such models. The terms of use (the license) differ from model to model, so you need to check them before using one in a business.
An everyday example
A dish you buy at a restaurant is a closed model. Getting the whole recipe and the ingredients and cooking at home is an open-source model.
Why it matters
You can use it without sending your data outside, it is cheap, and you can modify it as you like. It is also a force that keeps AI technology from being tied to just a few companies.
