What is a closed-weight artificial intelligence model?
Definition
A closed-weight artificial intelligence model is operated without distributing the parameter files required for independent local execution. Customers usually interact through an application programming interface or hosted product controlled by the provider.
The provider may offer strong reliability, support and managed infrastructure, but customers depend on its pricing, availability and data practices. Comparing closed and open models therefore involves governance and control as well as raw performance.
