Sonnet系列重大迭代,基准分暴涨且成本显著下降,对追求性价比的工程落地团队极具参考价值,建议关注实际部署效果。

Claude Sonnet 5.5 is out and it scores 70.6% on Terminal-Bench 4.0, up from Sonnet 5's 10.3%, at unchanged prices.

Claude Sonnet 5.5 已发布,在 Terminal-Bench 4.0 上得分 70.6%,高于 Sonnet 5 的 10.3%,且价格保持不变。

Overall, 30% cost reduction per-task due to faster speeds and fewer tool calls.

总体而言,由于速度更快且工具调用更少,每项任务的成本降低了 30%。

Keeps Sonnet 5's $2/$10 per million input/output tokens, half Opus 5.5's rates.

保持 Sonnet 5 每百万输入/输出 token 2 美元/10 美元的定价,仅为 Opus 5.5 费率的一半。

Its savings instead come from doing less work per job, since Anthropic says fewer tokens and tool calls cut the total cost of a task by up to 30%.

其节省主要来自于每项任务完成的工作量减少,因为 Anthropic 表示,更少的 token 和工具调用可将任务的总成本降低多达 30%。

Output also arrives more than 30% faster than Sonnet 5's, making Sonnet 5.5 Anthropic's quickest Sonnet yet.

输出速度也比 Sonnet 5 快 30% 以上,使 Sonnet 5.5 成为 Anthropic 迄今为止最快的 Sonnet 模型。

Users can dial an effort setting, trading longer reasoning and more self-checking for a higher cost per task.

用户可以调节努力程度设置,以换取更长的推理时间和更多的自我检查,从而承担更高的单项任务成本。

The economics might count for more than the leaderboard. Sonnet 5.5 operating at Low or Medium effort is able to exceed Sonnet 5's top score at about one-tenth the cost per task. On FrontierCode, it says Sonnet 5.5 at High effort scores roughly 10 points above Sonnet 5 at the same setting while costing approximately one-fifteenth as much per task.

经济效益可能比排行榜更重要。Sonnet 5.5 在低或中等努力程度下运行,能以约十分之一的单项任务成本超越 Sonnet 5 的最高分。在 FrontierCode 上,它表示在高努力程度下,Sonnet 5.5 的得分比相同设置下的 Sonnet 5 高出约 10 分,而每项任务的成本仅约为后者的十五分之一。

Anthropic characterizes Sonnet 5.5 as ideal for comparatively well-defined routine work, such as software debugging, coding, document production, building presentations and spreadsheets, and designing or refining interfaces.

Anthropic 将 Sonnet 5.5 定位为非常适合相对明确定义的日常工作的理想选择,例如软件调试、编码、文档制作、构建演示文稿和电子表格,以及设计或优化界面。
