FAQs
Which generative AI course is best for working professionals?
If you are working full-time, an inclusive program that covers LLM fundamentals, RAG systems, and deployment thinking tends to work best. You can check out programs like Scaler x IIT Roorkee Advanced AI Engineering, which are designed around applied projects and portfolio outcomes, which makes it easier to balance learning with professional commitments.
Should I learn transformers before building RAG apps?
You do not need deep transformer internals to start building RAG applications. A basic understanding of how LLMs consume inputs and produce outputs is enough, and deeper model knowledge can be added later if required.
What is RAG and why do production apps need evaluation?
RAG works by fetching relevant information from documents and using it to generate answers, so the model is not relying only on its training data. In production apps, evaluation matters because small retrieval issues can lead to incomplete or incorrect answers, and these problems often go unnoticed unless you actively test for them.
When should I fine-tune instead of using RAG?
Fine-tuning can be used when you need the model to follow a fixed style, format, or behavior across many responses. It is also used when retrieval does not improve results for a specific task or domain. The choice should be made by testing both approaches on the same data and comparing their outputs.
What is LLMOps and what should I monitor in production?
LLMOps refers to the processes used to deploy and maintain LLM applications over time. In production, monitoring typically includes response quality, request latency, usage cost, and recurring failure patterns introduced by prompt or model changes.
What projects impress recruiters for GenAI or LLM engineer roles?
Projects that demonstrate ownership across the full workflow tend to stand out. Examples include a RAG application with evaluation, a comparison between fine-tuning and retrieval on the same dataset, or a deployed application with logging, monitoring, and cost controls. A clear explanation of design decisions is as important as the implementation itself.
