The quality of your RAG (Retrieval-Augmented Generation) system depends more on your embedding strategy than on your choice of LLM. Poor embeddings mean irrelevant context retrieval, which no amount of prompt engineering can fix. This comprehensive guide explores production-ready embedding strategies—covering model selection, chunking approaches, hybrid search techniques, and optimization patterns that directly impact retrieval […]

Preparing data for RAG requires specialized ETL pipelines. After building pipelines for 50+ RAG systems, I’ve learned what works. Here’s the complete guide to ETL for vector embeddings.
Read more →Embedding Model Selection: Choosing the Right Model for Your RAG System
Introduction: Choosing the right embedding model is critical for RAG systems, semantic search, and similarity applications. The wrong choice leads to poor retrieval quality, high costs, or unacceptable latency. OpenAI’s text-embedding-3-small is cheap and fast but may miss nuanced similarities. Cohere’s embed-v3 excels at multilingual content. Open-source models like BGE and E5 offer privacy and […]
Read more →Embedding Fine-Tuning: Training Custom Embeddings for Domain-Specific Retrieval
Introduction: Off-the-shelf embedding models work well for general text, but domain-specific applications often need better performance. Fine-tuning embeddings on your data can dramatically improve retrieval quality—turning a 70% recall into 90%+ for your specific use case. The key is creating high-quality training data that teaches the model what “similar” means in your domain. This guide […]
