Jason Liu – Systematically Improving RAG Applications

Systematically Improving RAG Applications by Jason Liu: From Prototype to Production

Many AI engineers and product teams fall into the same trap: building retrieval-augmented generation (RAG) systems that perform well in demos but fail when exposed to real-world complexity. Jason Liu’s course, Systematically Improving RAG Applications, offers a clear path to overcome that challenge—transforming basic prototypes into production-grade systems that scale with confidence.

If your current RAG stack is underperforming, this course gives you the tools and systems to build intelligent, resilient, and continuously improving AI solutions.


Why Most RAG Systems Fail—and How to Fix Them

Common signs of RAG system breakdown include:

  • Users experience hallucinations when accuracy is most critical

  • Prompts are endlessly tweaked with minimal gain

  • Engineers can’t explain whether changes improved anything

  • Manual lookups outperform the AI

  • There’s no roadmap for meaningful improvement

Jason Liu introduces a systematic, feedback-driven framework that eliminates guesswork. It’s not just about using better models—it’s about applying structure, precision, and clarity at every step of the RAG lifecycle.


What You’ll Learn in the Course

Week 1: Evaluation Systems

Build synthetic evaluation data to identify failures early, long before users report them.

Week 2: Fine-Tuning Embeddings

Create domain-specific embedding models with limited data and achieve significant accuracy improvements.

Week 3: Feedback Collection Systems

Design user interfaces that collect rich, high-quality feedback—without disrupting user experience.

Week 4: Query Segmentation

Use real query logs to classify intent types, reveal bottlenecks, and prioritize engineering resources for maximum impact.

Week 5: Specialized Search Systems

Go beyond text—index tables, images, structured documents, and more for precise retrieval from diverse formats.

Week 6: Query Routing

Build intelligent systems that route each query to the most appropriate retriever, improving relevance and consistency across use cases.


The RAG Flywheel Methodology

At the heart of Jason’s approach is the RAG Flywheel: a continuous loop of synthetic evaluation, segmentation, fine-tuning, and feedback collection. This methodology replaces ad hoc fixes with structured, repeatable improvement cycles, resulting in long-term performance gains.

Real-world implementations using this method have achieved:

  • 85% recall for blueprint image retrieval

  • 90% document match rate through pre-processing

  • $50M in incremental revenue via improved product search

  • 20%+ boost in response accuracy

  • 30% reduction in irrelevant results through segmentation


Course Format and What You’ll Get

  • 6 Core Lectures: Pre-recorded modules delivering Jason’s full framework

  • Live Sessions + Office Hours: Real-time Q&A and problem-solving with Jason

  • 12+ Python Notebooks: Hands-on labs for immediate application

  • Private Slack Access: Connect with peers, get job leads, and receive ongoing support

  • Expert Guest Talks: Learn from engineers operating production RAG systems

  • Cloud & AI Credits: Over $2,000 in free credits for experimentation

  • Free Re-enrollment: Return to any future cohort at no cost

  • Certificate of Completion: Validate your expertise publicly

  • Maven Guarantee: Risk-free with refund available up to halfway through the course


Who This Course Is For

This program is designed for:

  • Engineers building or scaling RAG systems

  • AI product managers seeking measurable results

  • Data scientists focused on improving retrieval quality

  • Developers stuck in endless prototype iterations

  • Organizations frustrated by RAG systems that don’t perform under pressure

If you’re ready to stop guessing and start optimizing, this course gives you the complete playbook.


About the Instructor

Jason Liu has deployed AI systems across diverse domains, from policy models at Facebook to recommendation engines at Stitch Fix that drove over $50M in additional revenue. He brings practical, real-world insight to every part of this course—built for those serious about scaling intelligent AI systems.


Start Building Real RAG Systems—Not Just Demos

If your RAG system still relies on generic embeddings, vague evaluations, and hope-based iteration, you’re leaving massive performance gains on the table.

Jason Liu’s Systematically Improving RAG Applications gives you the tools, structure, and guidance to build mission-critical systems that learn, adapt, and outperform.
