Generative AI Leader Practice Question: Techniques to Improve Generative AI Model Output
A healthcare organization is using a generative AI model to summarize patient discharge instructions. They need to ensure the summaries are accurate and do not omit critical information. Which technique should they implement to reduce the risk of omissions?
⚠ Common exam trap
The trap here is thinking that a more powerful model or longer output will automatically capture all critical details, when the real issue is ensuring the model references the source document.

Correct answer & explanation
✓
Implement a retrieval-augmented generation (RAG) system that retrieves relevant sections of the discharge instructions and includes them in the prompt.
Retrieval-augmented generation (RAG) is the best choice because it grounds the model in the actual discharge instructions, reducing the chance of omissions. By retrieving and including relevant text in the prompt, the model can generate summaries that are comprehensive and accurate. Other techniques like fine-tuning or chain-of-thought do not directly ensure that all critical information from the source is captured.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increase the model's token limit to allow longer summaries that can include more details.
Why it's wrong here
A higher token limit allows longer outputs, but the model may still omit important information if it is not guided to include it. Length alone does not ensure completeness; the model might generate verbose but incomplete summaries. Grounding in the source is more effective.
- ✗
Fine-tune the model on a large dataset of medical summaries to improve its ability to capture key points.
Why it's wrong here
Fine-tuning can improve general summarization skills, but it does not guarantee that the model will include all critical information from a specific document. It might still miss details unique to the patient's instructions. RAG is more reliable for ensuring completeness with respect to the source.
- ✓
Implement a retrieval-augmented generation (RAG) system that retrieves relevant sections of the discharge instructions and includes them in the prompt.
Why this is correct
RAG ensures the model has access to the actual discharge instructions. By retrieving and including relevant sections, the model is less likely to omit critical information because it is grounded in the source text. This directly addresses the risk of omissions by providing the necessary context.
- ✗
Use chain-of-thought prompting to encourage the model to reason step by step.
Why it's wrong here
Chain-of-thought prompting can improve reasoning for complex tasks, but it does not guarantee that all critical information from the source is included. The model might still omit details if not explicitly instructed to extract them. It is more suited for problem-solving than for comprehensive summarization.
