Mellow Machines Lab open-sourced Mellow Harness, an agent harness for configurable AI hardware/companions. Centered on their System One model Jev, it uses minimal context management, authored personality, event history and state machines with a confined action space — achieving 227ms median decision latency (p95: 689ms). Demo: Buddygotchi, a pixel-pet coding companion synced to your agents.
