Plain explanation
Example
A company offers paid API access to a model but keeps the weights and training pipeline on its own infrastructure.Why it matters
Closed operation can support centralized updates and controls while limiting independent inspection, local deployment, portability, and reproducibility. Evaluation must use available evidence and actual service terms.Common misunderstanding
Misconception: closed means secret in every respect or automatically unsafe. Correction: disclosure and quality vary; closed access is one structural property, not a complete judgment.Sources and scope
Provides dated evidence on model development and provider ecosystems; access and disclosure can change by version and provider policy.
