Claude Code 更新：Opus 4.6 默认中等努力，移除旧版模型

AI 摘要

Claude Code 2.1.68 版本更新中，Opus 4.6 现默认对 Max 和 Team 订阅用户使用中等努力程度，以平衡速度与全面性，用户可通过 /model 随时调整。同时重新引入“ultrathink”关键词以启用下一轮的高努力模式，并从第一方 API 中移除 Opus 4 和 4.1，已固定这些模型的用户将自动迁移至 Opus 4.6。

- Opus 4.6 now defaults to medium effort for Max and Team subscribers. Medium effort works well for most tasks — it's the sweet spot between speed and thoroughness. You can change this anytime with `/model` - Re-introduced the "ultrathink" keyword to enable high effort for the next turn - Removed Opus 4 and 4.1 from Claude Code on the first-party API — users with these models pinned are automatically moved to Opus 4.6
