Why watch
A deep dive into AI harnesses with YC researchers and founders exploring how the same model weights can achieve dramatically different scores (30% to 95% on ARC-AGI) through better harness design. Covers self-improving RLMs, context caching strategies, and YC's internal QM/OpenClaw agent system for enterprise. For AI engineers, researchers, and founders building production AI systems.
