January 2026 was focused on standardization, onboarding, and performance improvements across the vector-search-cookbook. Key work included a comprehensive migration from legacy fts/gsi terminology to the unified search_based/query_based terminology across claudeai, cohere, llamaindex, openrouter-deepseek, and pydantic_ai; the addition of a query_based Capella Model Services tutorial with LangChain; and targeted RAG enhancements for Capella Model Services that load config from .env and refine index creation. Substantial quality work standardized terminology across tutorials, cleaned frontmatter and metadata for discoverability, updated .gitignore for new artefacts, and improved tutorial readability and user experience. These changes collectively improve developer onboarding, documentation consistency, and end-to-end Capella/LangChain workflows.
