Rows tagged “first-party” are the model vendor's own pricing; untagged rows are resale channels and may differ.

When to choose it

  • $2/$10 每百万 token 拿到 100 万上下文 + 看图 + 工具调用 + 分步推理,是 Claude 这一代里规格与价格最均衡的一档

Caveats

  • 同代 Opus 5 是 $5/$25、Fable 5 是 $10/$50,三者的上下文与模态规格在快照里完全一致 —— 价差反映的是能力,而能力差异我们没有实测数据,不替你下结论
