Anthropic 发布 Sonnet 5.5，称其为更便宜、更快速的工作伙伴

随着 AI 模型竞争持续升温，Anthropic 已发布最新版 Sonnet。这款公司中端模型的新版据称将比前代运行快得多，且成本显著更低。

该实验室将 Sonnet 5.5 描述为适合日常任务的理想助手，包括编程和创建办公文档。

作为 Sonnet 5.5 前代的 Sonnet 5，约在三个月前发布。当时，这一模型的核心卖点是高效部署 Agent——能够以低于竞争对手的成本运行 Agent。

与此同时，5.5 的最大卖点则是速度。Anthropic 声称，Sonnet 5.5 比前代快 30%，其 Token 消耗速度也显著更慢。

在 Anthropic 的模型体系中，Sonnet 的能力弱于 Opus 模型，但由于其敏捷性，在某些场景下可能更加实用。尤其是 Anthropic 的基准测试显示，Sonnet 5.5 在 Agent 编程方面的表现优于 Opus 5.5，这可能是因为它能够在不超出成本限制的情况下生成多个 Agent。

据称，Sonnet 5.5 还具备显著的网络安全能力。该公司表示，其网络安全能力与 Opus 5“相当”。因此，Anthropic 称，5.5 将成为首个适用与 Fable 和 Opus 相同网络安全防护措施的 Sonnet 模型。

该公司还计划在未来几周发布新版 Haiku——其最小型模型——但尚未给出具体发布日期。

过去一年，主要 AI 实验室密集发布新模型。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，并表示该模型将为其智能眼镜相关的即将推出功能提供支持。

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.

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.

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.

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.

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.

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.

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.
