联网查到的官方资料里,Claude 4.6 的 Opus 和 Sonnet 不是“谁全面碾压谁”,而是两个清晰定位的档位:

  • 论上限/最强能力:Opus 4.6 更好(旗舰,最适合“必须做对”的复杂任务)。 (Claude)
  • 论速度/性价比/日常好用:Sonnet 4.6 更好(更快、更便宜,而且很多场景已经非常接近 Opus)。 (Claude)

关键差异(用得上的那几个点)

1) 价格(API 标准价)

  • Opus 4.6:5/百万输入tokens5 / 百万输入 tokens,25 / 百万输出 tokens
  • Sonnet 4.6:3/百万输入tokens3 / 百万输入 tokens,15 / 百万输出 tokens (Claude)

如果你会跑大量请求或大规模 agent,Sonnet 的成本优势会非常明显。

2) 速度 & 最大输出长度

  • 延迟:Opus = Moderate(中等)Sonnet = Fast(更快) (Claude)
  • 最大输出:Opus 128K tokensSonnet 64K tokens(长报告/长代码生成时差别会体感很大)。 (Claude)

3) 上下文窗口(长文档/大代码库相关)

  • 两者默认都是 200K context,也都支持 1M context(Beta)(需要启用对应 beta header)。 (Claude)
  • 1M context 在 API 侧目前有门槛(如 usage tier 4 或自定义限额等),而且在“标准速度”下超过 200K 输入会触发更贵的长上下文费率。 (Claude)

4) 基准表现:Opus 更强,但 Sonnet 很接近(有些项目甚至反超)

从 Anthropic 发布的 Sonnet 4.6 系统卡对比表看: (anthropic.com)

  • SWE-bench Verified(真实修 bug 能力):Opus 80.8% vs Sonnet 79.6%(差距很小) (anthropic.com)
  • OSWorld-Verified(“会用电脑做事”的能力):Opus 72.7% vs Sonnet 72.5%(几乎持平) (anthropic.com)
  • Terminal-Bench 2.0(终端/系统任务):Opus 65.4% vs Sonnet 59.1%(Opus 优势更明显) (anthropic.com)
  • ARC-AGI-2(偏抽象/新颖推理):Opus 68.8% vs Sonnet 58.3%(更“难”的推理 Opus 更强) (anthropic.com)
  • GDPval-AA(偏“真实工作产出”ELO):Sonnet 1633 vs Opus 1606(Sonnet 在这项反而更高) (anthropic.com)

怎么选(最实用的结论)

你应该选 Opus 4.6 的情况

  • 任务本身很复杂、需要最深的推理、容错率低
  • 代码库重构、跨模块大改、或多代理工作流协调
  • 你经常需要超长输出(>64K tokens) (anthropic.com)

你应该选 Sonnet 4.6 的情况(大多数人属于这类)

  • 日常编程/办公/Agent 工具调用:希望快 + 省 + 够强
  • 要跑很多请求、对成本敏感
  • 你用 claude.ai:Sonnet 4.6 也是官方在 Free/Pro 默认推的主力档。 (anthropic.com)

一个很稳的策略

默认用 Sonnet 4.6(成本和速度最舒服),遇到“卡住/高风险/必须一次做对”的任务,再切到 Opus 4.6

如果你告诉我你主要用来做什么(写作/编程/数据分析/长文档/客服/多代理),以及你更在乎“成本还是成功率”,我可以按你的场景给一个更具体的选择建议(甚至给路由策略:哪些任务走 Sonnet,哪些任务升级 Opus)。
