首次量化 Sonnet 5 单任务成本高于 Opus 4.8，揭示 token 用量增加抵消单价优势核心解读
Artificial Analysis 分析显示，Claude Sonnet 5 在 Intelligence Index 上单任务成本为 $2.29，较 Sonnet 4.6 高约 2 倍，较 Opus 4.8 高约 15%，主要因 token 用量增加；Anthropic 推出优惠定价至 2026 年 8 月 31 日，输入 $2/1M tokens、输出 $10/1M tokens，随后恢复 $3/$15。
全文
Claude Sonnet 5 is more expensive (around +15%) per task than Opus 4.8 and much more expensive (2X) than Sonnet 4.6, even though its per-token price is lower than Opus.
Because it uses more tokens to complete the same kind of benchmark task. i.e. Sonnet 5 works harder and talks/thinks more, so the final bill becomes bigger even though each token is cheaper.
The promo pricing changes the story for now. Until August 31, 2026, Sonnet 5 is discounted to $2 per 1M input tokens and $10 per 1M output tokens, then it moves back to $3/$15 from September 1, 2026.

> Claude Sonnet 5 costs $2.29 per task on the Intelligence Index, a ~2x increase compared to Sonnet 4.6 and ~15% more than Claude Opus 4.8. This is driven entirely by increased token usage, making Claude Sonnet 5 one of the most costly models to run, behind only Claude Fable 5. Our results use standard $3/$15 pricing, however Anthropic is offering a one-third reduction to $2/$10 until September 1
