Arena launches agentic Max model router at 37% lower cost

A router that matches a frontier model's agentic performance while cutting cost per task by 37% shifts the economics of running multi-step agents, where model spend scales with every tool call. Teams deploying coding or browsing agents can route requests through Max instead of committing to one expensive model. Availability is currently free for a limited time, so it is easy to benchmark against direct Claude Fable 5.1 usage.
