Question formats
The Oracle Cloud Infrastructure 2024 Generative AI Professional (1Z0-1127) certification validates expertise in designing and implementing generative AI services on OCI. Candidates demonstrate knowledge of large language models, OCI Generative AI Service, retrieval-augmented generation (RAG), prompt engineering, fine-tuning, and embedding models. The exam covers practical use of OCI AI services including Cohere-based models hosted on OCI and integration with LangChain. It is aimed at AI engineers, data scientists, and cloud architects building production generative AI applications on the Oracle cloud platform.
Official prerequisite
No formal prerequisites; familiarity with OCI fundamentals and basic AI/ML concepts is recommended.
Recommended experience
Completion of the OCI Generative AI Professional learning path on Oracle University; basic Python programming knowledge.
6–12 months working with cloud AI services or LLM-based application development.
Should you skip this exam?
Professionals with no interest in AI/ML or those seeking a general OCI infrastructure credential (consider OCI Foundations or OCI Architect Associate instead).
Courseiva study tip
Complete Oracle's free OCI Generative AI learning path, practice with the OCI Generative AI playground, and focus on understanding RAG architectures and prompt engineering patterns.
