As 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.

UnverifiedThe Harness (constraint framework) design at the Agent layer is more important than the model backend, and a rigorous architecture can compensate for insufficient model capability to a certain extent.68% similarUnverifiedThere is a fundamental tension in the field of explainable AI: the more powerful a model is, the harder it tends to be to explain, and forcibly pursuing explainability may come at the cost of accuracy.66% similarUnverified模型的综合能力强弱和它对指令的忠实程度是两件不同的事64% similarUnverifiedRule是软约束，Scripts是硬约束，两者需要互补配合才能真正管住AI行为62% similarUnverifiedAs companies such as OpenAI and Anthropic deepen their research into model alignment, the new generation of models is beginning to be trained with a 'helpful resistance' capability, pushing back when users reason incorrectly or make harmful requests.61% similar
