Tiered-LLM Tooling: Local by Default, Escalate to Frontier#

When you build a chat or ops interface backed by an LLM, paying a frontier model for every interaction is wasteful — most interactions are cheap lookups, summaries, and routing. A tiered design serves the high-frequency majority with a small local model (e.g. an Ollama-served model on a GPU you already have) and escalates to a frontier model (e.g. Claude) only for the hard minority.
