Elvis Saravia Tests Jev as a New Primitive for Agent Harnesses
AI researcher Elvis Saravia shared early experiments integrating Jev into his custom agent harness, arguing its real value lies beyond speed and cost as a new primitive. Others highlight System One models' promise for continuous evaluation, long-horizon agents, and recursive self-improvement.
