A license is permission to use, modify, distribute, or commercialize a work under specified legal terms. In technology, those terms can govern both software code and data, even when the material is publicly available. section 4.12
Licenses can differ in several important ways:
- The MIT License is permissive: it allows reuse, including reuse inside proprietary software. section 4.12
- Other licenses may restrict use to noncommercial purposes, require attribution, or impose several conditions. section 4.12
- Code and data licenses are legally enforceable, so sharing material publicly does not necessarily remove its conditions of use. section 4.12
Licensing becomes especially contested when artificial intelligence systems are trained on code, images, video, voices, or other creative work. The dispute over GitHub Copilot illustrates the uncertainty: developers allege open-source license violations, while the defendants argue that the code was willingly shared. Copyright and fair-use questions do not automatically resolve whether license terms were followed. section 4.12
Licensing a creator's work or likeness
A YouTube creator can sign an individual contract licensing video footage to an AI developer. A person may also license a likeness or voice for an AI product, seeking payment or creative control. Such agreements can still produce disputes about consent, imitation, and the legal status of synthetic voices or faces. section 4.13 section 4.15
