Insights / AI
AI field notesThis is Resourcifi's library of AI guides: field notes on building agents, RAG systems and copilots, getting them through production, and understanding what they actually cost to run. Every article comes from client work, written by the engineers who ship it, not a content team paraphrasing press releases. Start with the agent and RAG build guides if you are deciding what to build. Read the deployment checklist and evaluation guides before anything touches real users. The cost and use case articles cover what budget holders ask first: what this costs over time and where it pays off in your industry. Everything here follows our Production-First AI methodology, which treats shipping as the starting line, not the finish. No trend pieces, no recycled hot takes, just what worked and what broke.
