Anthropic 发布 Sonnet 5.5，称其比前代更快更便宜
Anthropic releases Sonnet 5.5, which it calls a significantly cheaper, faster work partner
Anthropic 发布中端模型 Sonnet 5.5，官方称其比前代 Sonnet 5 快 30%，token 消耗明显更低。公司基准显示该模型在 agentic 编码上优于 Opus 5.5，并称其具备与 Opus 5 相当的网络安全能力，因此成为首个适用与 Fable 和 Opus 相同网络安全防护的 Sonnet 模型；公司还计划在未来几周发布新版本 Haiku。
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.
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.
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.
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 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.
