Which is NOT a category of pretrained foundational models available in the OCI Generative AI service?

The OCI Generative AI service organizes its pretrained foundational models into distinct categories based on their primary function. The officially documented categories are Generation models (for a wide range of text creation), Chat models (optimized for conversational dialogue), and Embedding models (for converting text into numerical vectors for semantic tasks). While a generation model can perform translation, "Translation models" is not listed as a separate, top-level category of foundational model available in the service.

A: Embedding models are a documented category in OCI Generative AI, used for tasks like semantic search and clustering. C: Chat models are a specific category offered by OCI Generative AI, fine-tuned for conversational applications. D: Generation models are a core category in OCI Generative AI, serving as the basis for many text creation tasks.

- Oracle Cloud Infrastructure Documentation. (2024). Generative AI Models. The documentation explicitly lists the available model families: "The pretrained foundational models that you can use in the Generative AI service are grouped into the following families: Generation, Chat, Embedding." This list does not include "Translation models" as a distinct family.
