A production-tested comparison of fixed-size, recursive, semantic, late chunking, and contextual retrieval for RAG — with 2026 benchmarks and the strategy I actually deploy.
GraphRAG promises smarter retrieval, but it can cost 40x more to index. Here is a production breakdown of GraphRAG vs vector RAG vs hybrid, with real 2026 cost, latency, and a decision matrix.
Five rerankers tested for production RAG in 2026 - Cohere 3.5, Voyage 2.5, Jina v3, Mixedbread mxbai-large-v2, and FlashRank. BEIR scores, latency, cost, and the call I made for our aggregator stack.
Choosing the wrong embedding model is the most expensive mistake in RAG. Here is a side-by-side comparison of OpenAI text-embedding-3-large, Voyage voyage-3-large, Cohere embed-v4, and Jina embeddings-v3 with real pricing math, latency, multilingual, and a clear decision matrix from production RAG experience.
After 3 months of building memory into BizChat and ServiceBot, here's the honest breakdown of Mem0, Letta, and Zep — pricing, benchmarks, and which one I'd pick for each use case.
A hands-on comparison of LangChain and LlamaIndex for production RAG pipelines in 2026, covering performance benchmarks, retrieval accuracy, and real engineering tradeoffs.
