Rules that say if you can use, change, or share an AI model.
A model license is the tiny sticker on a borrowed lawn mower. Mow your lawn, sure. Rent it to Dave or build a go-kart? Read the sticker.
It says how you may use, change, and share a model. You meet it before release, deployment, or buying AI.
Open-source-model
An open-source model can be used for business only if the license allows it.
Open weights
Open weights mean you can get the weights, not that you can use them any way you want.
Copyright
A model license is copyright permission written for a model.
On-premise AI
Companies usually check the license before they deploy a model privately.
