Which of these components is NOT a part of OCI AI infrastructure?

OCI Vault is designed primarily for managing and securing sensitive data, including encryption keys and secrets. While it plays a crucial role in ensuring data security within the Oracle Cloud Infrastructure ecosystem, it is not directly involved in the core functions of artificial intelligence (AI) or machine learning (ML) tasks.

In contrast, the other components mentioned, such as OCI Data Science Service, OCI Vision Service, and OCI Natural Language Processing Service, are specifically tailored for AI-related activities. The OCI Data Science Service provides a platform for building and deploying machine learning models, enabling data scientists to collaborate on their projects. OCI Vision Service offers capabilities for image analysis and recognition, which are fundamental in computer vision applications. Similarly, OCI Natural Language Processing Service focuses on processing and analyzing human language, supporting applications that require understanding text and conversation.

Thus, while OCI Vault is essential for security management, it does not serve as a component of AI infrastructure like the other options do.
