Anthropic releases Sonnet 5.5, which it calls a significantly cheaper, faster work partner

Anthropic 发布 Sonnet 5.5，称其为更经济、更高效的工作伙伴

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. 随着 AI 模型大战的持续，Anthropic 发布了其最新版中端模型 Sonnet。该公司表示，新版本的工作速度将比前代产品快得多，且成本显著降低。

The lab describes Sonnet 5.5 as an ideal assistant for everyday tasks — including coding and creating office documents. Sonnet 5, 5.5’s predecessor, 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. 该实验室将 Sonnet 5.5 描述为处理日常任务（包括编程和创建办公文档）的理想助手。Sonnet 5.5 的前身 Sonnet 5 大约在三个月前发布。当时，该模型的卖点在于高效的智能体部署——即能够以低于竞争对手的成本运行智能体。

The big selling point with 5.5, meanwhile, is speed. Anthropic claims that Sonnet 5.5 is 30% faster than its predecessor and that its rate of token burn is significantly slower. 与此同时，5.5 版本的一大卖点是速度。Anthropic 声称，Sonnet 5.5 的运行速度比前代产品快 30%，且其 Token 消耗率显著降低。

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. 在 Anthropic 的模型层级中，Sonnet 的性能虽不及 Opus 模型，但由于其灵活性，在某些情况下反而更具实用性。特别是在 Anthropic 的基准测试中，Sonnet 5.5 在智能体编程方面的表现优于 Opus 5.5，这很可能是因为它能够在不超出成本限制的情况下生成多个智能体。

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 to the same cyber safeguards that apply to Fable and Opus. 据悉，Sonnet 5.5 还具备强大的网络安全能力，公司声称其网络安全水平与 Opus 5 “相当”。因此，Anthropic 表示，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。

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. 该公司还计划在未来几周内发布其最小模型 Haiku 的新版本，但并未给出确切的发布日期。

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. 过去一年里，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，包括其主打中端和经济实惠市场的 Sol 和 Luna 的增强版。Meta 也宣布了一款新模型，称其将为智能眼镜即将推出的相关功能提供支持。
