ARC 1.0: A 0.6B Apache 2.0 Model That Routes AI Agents Across Cloud and Local Models

Balance- · reddit · 2026-11-14

The open-source ARC (Adaptive Routing Controller) hits 1.0 under Apache 2.0 with just 0.6B parameters. It reads an agent's conversation and produces signals for choosing which model to use and how much reasoning effort to apply; the application then combines those signals with its own model lineup, prices and policies to route the next request. Could be quite useful for hybrid cloud/local agent setups if it works well.
