Anthropic's Claude Opus 5 introduces an "effort" parameter that allows users to trade off computational cost for model capability. This parameter, with five distinct levels, controls the amount of internal reasoning the model performs before generating a response. Higher effort settings result in more reasoning, leading to increased costs and latency, while lower settings reduce these factors at the potential expense of response quality. Users are advised to recalibrate their effort settings for Opus 5, as the levels do not directly correspond to those in Opus 4.8, and lower settings may now be viable for production tasks. AI
