Smart LLM Telemetry Saves Costs, Avoids Over‑logging
LLM logging gets expensive fast. Prompt/response storage. Token metadata. Latency traces. Third-party observability bills. Most teams over-log… then panic at the invoice. If you’re building with LLMs in production, you need telemetry without exploding cloud costs. Here’s how to log smarter ⤵️🩷

Observability, Control Flow, Interruption: Key to Safe Agent Orchestration
Terrific thread on agent orchestration architectures. "If an agent started making confident but wrong decisions, how many actions would execute before I could stop it?" The three magic words are "observability", "control flow ownership", and "interruption".
