LLM Engineering & Retrieval

Practitioners developing modern large language models must master concepts ranging from tokenisation strategies to production evaluation methodologies, according to recent analysis. A separate engineering challenge involves mitigating data staleness in production systems, where a temporal layer was implemented after an AI tutor provided outdated information, demonstrating a common failure mode in standard Retrieval-Augmented Generation (RAG) architectures.
