随着 AI 模型竞争持续升温，Anthropic 发布了旗下中端模型 Sonnet 的最新版本。公司表示，该模型的运行速度远快于前代版本，成本也显著更低。
As the AI model wars continue, Anthropic has released the newest version of Sonnet, the company’s mid-tier model, which it says will work much faster (and for significantly less) than its predecessor.
Anthropic 将 Sonnet 5.5 描述为日常任务的理想助手，可用于编程、创建办公文档等工作。
The lab describes Sonnet 5.5 as an ideal assistant for everyday tasks — including coding and creating office documents.
Sonnet 5.5 的前代版本 Sonnet 5 于约三个月前发布。当时，该模型的卖点是高效的智能体部署，即能够以低于竞争对手的成本运行智能体。
5.5’s predecessor, Sonnet 5, was announced about three months ago. At the time, the model’s selling point was efficient agentic deployment — the ability to run agents at a lower cost than competitors.
相比之下，5.5 的主要卖点是速度。Anthropic 宣称，Sonnet 5.5 比前代模型快 30%，其词元消耗速率也显著降低。
The big selling point with 5.5, meanwhile, is speed. Anthropic claims that Sonnet 5.5 is 30 percent faster than its predecessor, and that its rate of token burn is significantly slower.
在 Anthropic 的模型层级中，Sonnet 的能力不及 Opus，但由于更加灵活敏捷，在某些情况下可能更实用。特别是，Anthropic 的基准测试显示，Sonnet 5.5 在智能体编程方面表现优于 Opus 5.5，可能是因为它能够在不超出成本限制的情况下启动多个智能体。
In the Anthropic hierarchy of models, Sonnet is less powerful than the Opus model, but can be more useful in certain circumstances because its agility. In particular, Anthropic’s benchmarks show Sonnet 5.5 performing better than Opus 5.5 on agentic coding, likely because of its ability to spawn multiple agents without exceeding cost limits.
据称，Sonnet 5.5 还具备强大的网络安全能力。公司表示，其网络安全能力与 Opus 5“相当”。因此，Anthropic 称 5.5 是首个适用与 Fable 和 Opus 相同网络安全防护措施的 Sonnet 模型。
Sonnet 5.5 is also said to have significant cyber capabilities, with the company claiming that it has “comparable” cyber capabilities to Opus 5. As a result, Anthropic says that 5.5 is the first Sonnet model that will be subject the same cyber safeguards that apply to Fable and Opus.
该公司还计划在未来几周发布新版 Haiku——其体积最小的模型——但尚未给出确切日期。
The company also plans to release a new version of Haiku — its smallest model — in the coming weeks, although it didn’t give a firm date as to when that would happen.
过去一年，各大 AI 实验室密集发布了多款新模型。就在上周，OpenAI 发布了多款新模型，其中包括其中端模型 Sol 和经济型模型 Luna 的增强版本。Meta 也宣布了一款新模型，并称该模型将为其智能眼镜即将推出的一项功能提供支持。
The last year has seen a flurry of new model releases from the major AI labs. Just last week, OpenAI released a number of new models — including enhanced versions of Sol and Luna, its mid-tier and budget-friendly models. Meta also announced a new model, which it said would power an upcoming feature associated with its smart glasses.
