UnverifiedClaude Opus 4属于推理增强型模型，处理复杂任务时会启动扩展思维链（Extended Thinking），单次复杂推理的算力成本可达普通模型的20-50倍79% similarUnverifiedThe adaptive thinking mechanism allows the model to dynamically determine the depth of reasoning based on problem difficulty, answering simple questions directly and only engaging in full reasoning for complex ones.75% similarVerifiedClaude's Extended Thinking mode causes the model to perform an explicit internal reasoning chain before output, improving complex task quality but significantly increasing token consumption.73% similarUnverifiedOpus-level models, with their larger context windows and stronger reasoning capabilities, are considered to deliver more reliable autonomous execution performance.73% similarUnverifiedTest-time compute scaling improves performance on complex reasoning tasks by investing more computation during the inference stage through methods such as extending the chain of thought, multi-path sampling with best-of-n selection, and self-verification reflection.72% similar
