社交平台X上，谷歌工程师Patrick C Toulme据此提出一个推测：Opus 5.5可能经由Anthropic内部更强大的"教师模型"Model 2蒸馏而来，并可能是首个体现"递归自我改进"（RSI）路径的产品模型。
目前没有公开证据直接证实这一推断，但Anthropic已公开确认Model 2的存在，且该公司发布的RSI相关文章显示，AI参与AI研发的程度正在快速深化，这使得上述猜测具备一定背景。
对于投资者和行业观察者而言，这一事件真正值得关注的，是它将三条此前相对分散的趋势串联在了一起：更强的内部模型持续迭代、AI深度介入AI研发流程、以及更小更便宜的产品模型同步涌现。
如果这条路径成立，模型能力提升与推理成本下降将有可能同时发生。
Opus 5.5为什么值得关注？
华尔街见闻提及，Anthropic将Claude Opus 5.5定位为其5.5系列的首款发布，性能在多数任务上与Claude Fable 5.1持平，但运行成本较Opus 5下降40%，输出速度提升逾30%。
定价层面的降幅尤为显著。输入和输出token价格分别为每百万4美元和20美元，较Opus 5下降20%；而在代理任务和编程场景中占主要成本的缓存读取，则从每百万0.50美元降至0.20美元，降幅达60%。
