Anthropic推出了Claude Opus 5大模型[1]。新模型相比前代Opus 4.8实现了显著的性能提升，同时维持原有价格——输入令牌$5/百万，输出令牌$25/百万[1]。
Claude Opus 5在多个权威评估基准上实现了业界领先成绩[1]。在Frontier-Bench v0.1评估中，其性能相比Opus 4.8提升一倍以上[1]。在ARC-AGI 3评估上，该模型的得分达到次优模型的三倍[1]。在计算机使用能力方面，Claude Opus 5在OSWorld 2.0基准上以仅Fable 5成本三分之一的价格超越了后者的最佳成绩[1]。在Zapier AutomationBench上的通过率约为次优模型的1.5倍[1]。
在代码编程和科学研究领域表现尤为突出[1]。软件工程任务中的性能翻倍提升[1]，有机化学任务上较Opus 4.8提高10.2个百分点，蛋白质相关任务上提高7.7个百分点[1]。在CursorBench 3.2最大努力设置下，该模型性能接近Fable 5峰值成绩，但成本仅为一半[1]。
新模型已上线所有平台，成为Claude Max的默认模型和Claude Pro的最强选择[1]。用户可选择Fast模式，其运行速度约为默认速度的2.5倍，但价格为基础价格的两倍[1]。此外，Claude Opus 5在自动行为审计中被评为目前最对齐的模型，欺骗行为率最低[1]。
在某些专业领域，该模型仍存在差距[1]。生物学研究和网络安全方面的性能仍落后于Mythos 5[1]。
Anthropic has released Claude Opus 5, a new large language model that delivers substantial performance improvements over its predecessor Opus 4.8 while maintaining identical pricing [1]. The model is now available across all platforms as the default option for Claude Max and the most advanced model for Claude Pro [1].
The new model is priced at $5 per million input tokens and $25 per million output tokens [1]. Despite the performance enhancements, Anthropic has kept costs unchanged from the previous generation [1].
Claude Opus 5 demonstrates leading performance across multiple benchmarks [1]. On Frontier-Bench v0.1, it surpasses all competing models with more than double the performance of Opus 4.8 [1]. The model achieves results within 0.5 percent of Fable 5's peak score on CursorBench 3.2's maximum effort setting, while costing half as much [1]. On the ARC-AGI 3 evaluation, Claude Opus 5 scores three times higher than the second-best model [1], and on Zapier AutomationBench, its pass rate is approximately 1.5 times that of the next-best performer [1]. For the OSWorld 2.0 computer use benchmark, it exceeds Fable 5's best results at one-third of the cost [1].
In specialized domains, Claude Opus 5 shows notable improvements over Opus 4.8: it scores 10.2 percentage points higher on organic chemistry tasks and 7.7 percentage points higher on protein-related tasks [1]. A faster operating mode runs approximately 2.5 times faster than the default speed at double the base price [1].
The model also demonstrates strong alignment properties, achieving the lowest deception rate in automated behavioral audits among all models tested [1]. However, it remains behind Mythos 5 in biology research and cybersecurity applications [1].
