Local-First LLM Routing - Use Small Models for Easy Questions and Cloud Models for Hard Ones

Wed, 01 Jul 2026 00:00:00 +0000

Every LLM call costs something.

Sometimes the cost is money. Sometimes it is latency. Sometimes it is privacy.

If you send every request to a frontier model, you burn budget on tasks a small local model could have handled. If you run everything locally, the easy cases feel great until a harder reasoning task shows up and the answer falls apart.

The better pattern is a local-first routing gateway.

Put a thin layer between your chat UI and your models. The gateway looks at each request, sends simple work to a local model, and escalates harder work to a remote model. The user still sees one assistant. The system decides which model should answer.
