Open Source AI
AI systems released with open code and, often, open model weights.
Definition
Open source AI refers to AI systems released with open code and, in many cases, open model weights (the trained numbers that make up a model), so that others can inspect, run, and modify them. The exact meaning varies — some releases share training code and data, others share only the trained weights under a license. This openness supports independent research, local deployment, and adaptation without depending on a single provider.
