- 1The AI Terms Everyone Is Getting Wrong: Open Source vs Open Weight▼The Big AI Terms Everyone Is Getting Wrong: Open Source, Open Weight And Proprietary
A widely shared explainer argues that most people misuse key AI terminology, conflating 'open source', 'open weight' and 'proprietary' models. It points out that releasing model weights is not the same as true open source, which would also include training code and data, while proprietary systems remain fully closed. The piece is prompting discussion about how loosely these labels are applied across the AI industry.
