Boris Cherny 称 Claude Opus 5.5 已成为他近几周的日常主力模型。他让 Opus 5.5 与 Fable 5.1 各自把 HAProxy 从 C 移植到 Rust，两者都通过了几乎全部测试，但 Opus 5.5 用时 9.5 小时，快于 Fable 5.1 的 12 小时，成本低 51%。据其引用的官方介绍，Opus 5.5 是 Claude 5.5 家族首个模型，大多数任务表现达到 Claude Fable 5.1 水平，运行成本比 Opus 5 低 40%。
推荐理由

Opus 5.5 is a really good model. It's been my daily driver the last few weeks.
We had Opus 5.5 and Fable 5.1 each port HAProxy from C to Rust. Both passed nearly all of HAProxy's tests, but Opus 5.5 finished in 9.5 hours compared to Fable 5.1's 12 hours, and for 51% less cost.
Introducing Claude Opus 5.5, the first model in our new Claude 5.5 family. It performs at the level of Claude Fable 5.1 for most tasks, and costs 40% less to run than Opus 5.在 X 查看被引用的帖子
