A practical guide to LLM cost observability: structured logging, Langfuse dashboards, OpenTelemetry metrics, per-tenant budgets, and the unit economics finance actually needs.
A practical guide to embedded copilots: context from product state, server-side assembly, RBAC, and UI patterns that fit existing workflows instead of a floating chat widget.
A practical security guide for multi-tenant products — why system prompts are not enough, where attacks actually land, and the integration patterns that hold up in production.
A practical guide to the server-side layer between your app and the model — auth, rate limits, routing, logging, and the patterns that keep AI features production-ready.
