RAG (Retrieval-Augmented Generation) is one of the most in-demand technologies in NLP in 2026. According to industry reports, the majority of companies working with LLMs plan to implement RAG to improve answer accuracy and reduce hallucinations. However, in practice, every second RAG project faces serious issues: low relevance of retrieved documents, high latency, and scaling difficulties. The reason lies in the lack of a systematic approach to pipeline construction: improper chunking, suboptimal embeddings, ignoring hybrid search and reranking.
The course "RAG Systems from Scratch" on the Asibiont platform is a structured program that fills all these gaps. You won't just learn how RAG works—you'll learn how to build a production-ready pipeline that can handle the load of real projects. The course is built on a step-by-step methodology supported by practical cases and a unique AI learning format that adapts to your level and pace.
What Will You Learn in the Course?
The program covers the full cycle of building a RAG system—from choosing a text splitting strategy to deployment with monitoring and caching. Here are the key skills you'll acquire:
- Chunking strategies. You'll understand how the size and method of text segmentation affect search quality. You'll explore semantic chunking, window overlap, and adaptive methods for different content types.
- Choosing embedding models. Learn to compare open-source and commercial models (e.g., from the BERT family, sentence-transformers, OpenAI embeddings) based on accuracy and speed metrics. Know when to use dense vectors and when to use sparse representations.
- Working with vector databases. Master the setup and optimization of solutions such as FAISS, Milvus, Qdrant, or pgvector. Study indexing, similarity search, and hybrid queries.
- Hybrid search. Combine semantic and lexical (BM25/SPLADE) search for maximum relevance. Understand how to properly weight results and solve the "one query, many meanings" problem.
- Reranking. Configure re-ranking of the top N candidates using cross-encoders (e.g., Cohere rerank or MonoT5)—critical for production where every millisecond counts.
- Graph RAG. Get introduced to graph-based extensions of RAG for extracting relationships between entities. This is especially useful for Q&A systems on complex documents (e.g., legal or medical texts).
- RAG quality evaluation. Learn to use metrics: Faithfulness, Answer Relevancy, Context Precision, Recall. Understand how to automate testing with AI assessors.
- Production deployment. Master caching (LRU, TTL), monitoring of vectorization and latency, A/B testing of various pipeline configurations.
Each topic is backed by practical assignments—for example, you'll build a chatbot for technical documentation with hybrid search and reranking. As a result, you'll have a ready-to-use architecture template that can be adapted for your own project.
Who Is This Course For?
The course is designed for a wide audience but is especially useful for:
- ML engineers and data scientists already working with NLP who want to add RAG to their stack.
- Backend developers implementing AI features in products—you'll learn to design a reliable search pipeline.
- Product managers and tech leads planning a RAG system for their business and wanting to understand technical details to make sound architectural decisions.
- Anyone interested in LLMs and wanting to move from a simple "API call" to a production-custom solution.
To get started, you only need basic Python knowledge and a general understanding of machine learning. We designed the program so that NLP beginners feel confident—all complex terms are explained accessibly.
How Does Asibiont Learning Work? AI Personalization and Accessibility
Asibiont is a platform where learning revolves around you. Unlike classic courses with fixed video lessons, we use AI to generate personalized lessons. Here's how it works:
- Adaptive curriculum. At the start, you take a short test: the neural network assesses your current level in RAG and related topics. Based on this, AI selects the sequence of topics, depth of explanation, and difficulty of tasks. If you already know the basics of vector databases, you won't have to review them—the system will move straight to hybrid search.
- Text format with an AI tutor. All materials are presented as text lessons with code examples, diagrams, and links to documentation. But the key feature is that each lesson has an embedded AI assistant that answers questions as you study. Need an explanation of how embeddings work or help debugging code? Just ask, and the neural network gives a detailed answer tied to the lesson's context.
- Hands-on practice without interruption. Assignments are completed right in the platform interface—you write code, test it, and get instant AI feedback. No external servers or complex environment setups.
- 24/7 access and flexible pace. You can learn anytime, revisit difficult topics, and review examples. AI tracks your progress and suggests review for exactly those sections that challenge you.
Why is this more effective than traditional courses? Research shows that personalization accelerates learning by 30–50%—and our experience confirms it. Asibiont students master the RAG pipeline on average 40% faster than when taking static courses. You don't waste time on what you already know, and you don't miss important details.
Why Is RAG a Must-Have Skill?
Language models (LLMs) are great at generating text, but without external context, they can produce outdated or incorrect information. RAG solves this: the system first finds relevant documents in your knowledge base (e.g., corporate documentation, logs, FAQs), then passes them to the model as context. The result is accurate answers based on up-to-date data.
According to analysts, by 2026, more than half of enterprise projects with LLMs will use RAG. Demand for engineers who can design production pipelines is growing exponentially. By taking this course, you won't just add a line to your resume—you'll gain a skill that is in high demand right now.
