's EnvHarness is an open-source framework for training self-evolving AI agents to learn in dynamic environments. As of October 16, 2026, Google researchers have open-sourced EnvHarness, which dynamically adapts training environments to an agent's weaknesses without modifying the agent, environment, or evaluation system. Researchers say this improves learning effectiveness and efficiency and helps agents overcome weaknesses, which matters industrially because it could make agent development faster and less resource-intensive.
