From 5e2f7078d9a509798a69e28745c3cc12df16db8d Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Wed, 25 Mar 2026 08:34:56 +0000 Subject: [PATCH] feat: implement multi-tier intelligent model routing This expands the intelligent routing feature (which previously only supported a binary light/heavy split) to support an arbitrary number of tiers, each with its own model and threshold score. - Update `RoutingConfig` to use a `Tiers` array. - Handle backward compatibility for `light_model` and `threshold`. - Update `Router.SelectModel` to iterate over sorted tiers and select the tier with the highest threshold that is <= the complexity score. - Update `AgentInstance` initialization to resolve candidates for all routing tiers instead of just the light model. - Update the frontend UI to display, add, edit, and remove routing tiers.
