UnverifiedIf a coding agent product's advantages come primarily from the harness, those advantages may be quickly erased once competitors connect to the same underlying model and optimize their own harness.80% similarUnverifiedThe effectiveness of a coding agent is the product of the model and the harness; ignoring the harness and purely pursuing model upgrades is like putting a stronger engine in a race car while ignoring the gearbox and tires.77% similarUnverifiedAs model capabilities become increasingly homogenized, inference efficiency and deployment convenience are becoming key factors for differentiated competition.76% similarUnverifiedMore capable models are not necessarily more dangerous; they may actually perform better at compliance, and capability and alignment can improve in tandem.72% similarUnverifiedAs the capabilities of foundation models converge toward homogeneity, harness quality is increasingly becoming a decisive factor in the actual performance of agents, and a considerable portion of the performance gap between OpenAI's Codex and Anthropic's Claude Code stems from differences in harness design.72% similar
