Insights on AI workflow engineering

The most resilient AI systems treat the LLM as a component called via API, not as a framework that owns the architecture. These are the patterns that distinguish AI features that ship reliably from ones that keep breaking.

Three concerns drive most teams toward self-hosting: data privacy (your inputs and outputs never leave your infrastructure), cost predictability (no per-seat SaaS fees), and operational control (debug and optimize on your own terms).

Most teams start by calling an LLM API directly. It works — until it doesn't. Typed schemas, step composition, and explicit data contracts are what separate prototype code from production AI systems.

Dify, Flowise, n8n and LangChain solved real problems — fast time to prototype, visual drag-and-drop, pre-built integrations. But each one extracts a hidden tax that compounds over time: your workflow logic becomes their proprietary format.

Prompts are code. They encode business logic, edge-case handling, and output contracts. Treating them as disposable configuration is the root cause of most AI feature regressions.
