# Anthropic发布Sonnet 5.5：速度快30%，价格更低

Anthropic发布Sonnet 5.5，官方称在大多数任务上运行速度提升30%以上，成本降低最高30%。定价与Sonnet 5相同，但在各项基准测试中全面超越前代，实际运行成本更低。该模型目前已成为Anthropic API上的默认Sonnet模型，支持100万token上下文，输入$2/百万token，输出$10/百万token，缓存读取$0.20/百万token。对开发者来说，这意味着在同等预算下可获得更快响应和更高质量输出，适合需要高频调用的大规模应用场景。

## English Version

**Anthropic Releases Claude Sonnet 5.5: 30% Faster and Cheaper**

Anthropic released Claude Sonnet 5.5, claiming it runs 30%+ faster and costs up to 30% less for most workloads. Despite sharing the same price as Sonnet 5, it outperforms its predecessor on every benchmark. The model is now the default Sonnet on the Anthropic API with a 1M token context window, priced at $2/$10 per million tokens with $0.20/Mtok cache reads. For developers, this means faster responses and better quality at the same budget, making it well-suited for high-frequency, large-scale applications.
