AI 导读
Anthropic 发布 Claude Sonnet 5.5，称其与 Sonnet 5 定价相同，但完成同样工作通常只需更少 token，官方测试中每任务成本比上一代最多低 30%。输出生成速度提升超过 30%，官方称其为目前最快的 Sonnet 模型。
推荐理由
在定价不变的前提下给出每任务成本与生成速度的量化变化，读者可据此估算同等工作负载的开销。
正文
Sonnet 5.5 is priced the same as Sonnet 5, but it typically needs far fewer tokens to do the same work. In our testing, it costs up to 30% less per task than its predecessor.
It also generates output more than 30% faster, making it our fastest Sonnet model to date. https://t.co/UYFInIzzTY
