The fifth installment of the Stack Overflow Blog series presents a practical framework for running large language model systems, focusing on observability, cost control, request routing between models, safe fallback, and an immediate kill switch. The central idea is to route every model operation through a single gateway that connects measurement, control, identity, and infrastructure.
OpenTelemetry achieved graduated project status at CNCF in May 2026 after meeting criteria related to production adoption, governance, security, and API stability. The project says its next phase will focus on observing AI-based workloads, browsers and mobile devices, and expanding deployment and management tools at scale.
Adriana Villela and Diana Todea explain why developers should handle observability directly, and present a practical path that begins with low-effort automatic instrumentation and is then supplemented with thoughtful manual additions. They also review local tools for viewing OpenTelemetry data and warn about maturity and setup challenges and differences in language support.
