Understand the models
Explain how large language models generate text, how prompts shape output, and where they fall short.






























A Professional exam for people who build generative AI applications on Oracle Cloud Infrastructure. It covers how LLMs work, OCI’s managed Generative AI service, and patterns such as retrieval-augmented generation and chat. Oracle’s 2025 outline gave the OCI service 40% and the others 20% each, but objectives change, so check current weights.
Explain how large language models generate text, how prompts shape output, and where they fall short.
Work with pretrained models, fine-tuning and embeddings through OCI’s Generative AI service.
Build retrieval-augmented generation that grounds answers in your own documents.
Wire models, retrieval and memory into a chat application with common frameworks.
We design this course ourselves. Oracle runs the exam and issues the credential, and LUNARTECH is independent of Oracle.
Begin with the machinery: transformers, attention and next-token prediction. Knowing how a model turns a prompt into text explains its strengths, its limits and why the same input can give different answers.
You build A worked trace of how one prompt becomes tokens, probabilities and a reply.
Output quality depends on the instruction and on how the model samples. You write prompts in proven patterns and tune temperature, top-p and length limits to fit the task, from strict extraction to open drafting.
You build A prompt test sheet comparing patterns and parameter settings on one task.
A model that sounds sure can still be wrong. You study hallucination, stale knowledge, bias and prompt injection, and learn to measure output quality with checks you can repeat.
You build A failure log for one model, with a mitigation chosen for each type of failure.
Meet the managed service: the hosted pretrained models, the playground and the APIs that expose chat, text generation and embeddings. You learn to pick a model for a task and to call it from code.
You build A script that calls two hosted models and compares their answers on the same inputs.
When prompting is not enough, you adapt the model. You prepare training data, run fine-tuning on a dedicated AI cluster, host the result for use, and judge whether it beat the base model.
You build A fine-tuning plan with a prepared dataset and a comparison against the base model.
Retrieval starts with meaning. You turn text into embeddings, store them where they can be searched, and learn how chunk size and overlap decide whether the right passage is found.
You build An embedded, searchable chunk store built from a set of real documents.
RAG grounds answers in your own documents. You build the whole loop of retrieve, assemble the prompt, generate and cite, and learn to measure whether retrieval is helping or misleading the model.
You build A RAG assistant over real documents that answers with citations.
Frameworks turn model calls into applications. You use LangChain to connect OCI models to prompt templates, retrievers and output parsers, and learn when a framework helps and when plain code is simpler.
You build A LangChain application that answers questions with OCI models and a retriever.
A chat that forgets is frustrating, and one that remembers everything is costly. You compare memory strategies, manage sessions and context size, and put guardrails around what the application will say.
You build A multi-turn chat application with memory and guardrails.
Join the models, retrieval, memory and framework into one assistant that serves a real need. You design it, choose the model and customization, test it for faults, and justify each choice.
You build A document-grounded assistant on OCI, with a design record of every choice.

LUNARTECH Academy has been the most empowering learning experience of my life, giving me a clear, structured path from the absolute basics to building real-world AI systems with confidence.
Your page is fantastic. As a bachelor’s student in Data Science now accepted for a master’s at UConn, your work has been a real source of motivation.
The programme’s clear, bite-sized content and practical projects dramatically improved my speed from fuzzy idea to MVP and my ability to communicate AI value. I followed the system, and it works.
I really appreciate your teaching style and the way you break down complex topics. It has been incredibly helpful.
After years working mainly with R for econometrics, I found your Python machine learning course a refreshing and engaging way to learn Python.
As a Data Science graduate, I want to thank you for the effort you put into making videos to support growing data scientists.
I’ve been following your work since taking your machine learning course, and I’m impressed by your practical approach to applying AI.
One standard behind every course, from the first lesson to long after the last.
Apply every idea to real problems, so it becomes something you have used, not only seen.
We keep courses current with the tools, techniques and skills the field asks for.
Study at your own pace, from anywhere, at any hour.
