## 更新内容
- Opus 4.6 现为 Max 和 Team 订阅用户的默认设置，采用中等算力模式。该模式在速度与深度之间取得最佳平衡，适用于大多数任务。您可随时通过 `/model` 进行更改
- 重新引入 "ultrathink" 关键词，可在下一轮对话中启用高算力模式
- 从 Claude Code 的官方 API 中移除 Opus 4 和 4.1 版本 — 固定使用这些模型的用户将自动迁移至 Opus 4.6
## What's changed
- 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
