Improving Accuracy of LLM Applications

by DeepLearning.AI × Lamini & Meta

IntermediateCourseFree~1-2 hours

A systematic workflow — evals, prompting, then fine-tuning — to push an LLM app from flaky to reliable.

Start LearningReviewed July 3, 2026

Overview

Rather than treating fine-tuning as a first resort, this course teaches a systematic accuracy-improvement workflow. You build an evaluation set, apply prompt engineering and few-shot examples, and only then fine-tune (using memory-tuning techniques) to reduce hallucination on a text-to-SQL task. It shows how to combine techniques and measure each step's impact — exactly the discipline production teams need.
