AI 导读
Anthropic 发布 Sonnet 5.5，定价与 Sonnet 5 相同，但完成同样工作通常需要更少 token，官方测试中每任务成本最多降低 30%，输出生成速度提升超 30%，是其迄今最快的 Sonnet 模型。转发该消息的作者 @kimmonismus 认为它相比 GPT-6-Sol 价格相当却更高效、更快、整体表现更好，接近 Opus 5.5 但速度更快、成本更低。
推荐理由
作者把 Sonnet 5.5 与前代和竞品放在一起比较，读者可据此判断速度与成本变化对模型选型的参考价值。

Let that sink in: "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."
Same pricing compared to GPT-6-Sol, but much more efficient, much faster and - on top - much much better in general.
OpenAI has to release a crazy good model tomorrow. Anthropic is so freaking back. I think people dont fully grasp how crazy this us. Its just short to Opus 5.5 but much faster, cheaper.
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在 X 查看被引用的帖子
