arena mode

Arena mode in Grok Build is a feature that automatically ranks and adjudicates outputs from multiple AI coding agents, reducing the need for manual comparison. This mode works alongside parallel agents, which allow users to spawn up to eight agents simultaneously. The feature is part of xAI's Grok Build, a browser-like collaborative coding environment focused on multi-agent workflows and automated evaluation. Arena mode is designed to streamline agent output comparison, making it a tool for developers using AI-assisted coding within the Grok Build environment.
