Key Points

  • Manus AIの3つの利用モード(Chat/Standard/Max)を、用途別に使い分けることでクレジット消費を大きく抑えられると解説しています。
  • 「Maxをすべてに使うのが最大のミス」で、60%超のタスクはStandardまたはChatで十分だとして判断手順(決定ツリー)を提示しています。
  • 具体的な節約テクニックとして、単純なQ&AはChatで行うこと、5〜6プロンプトごとに新セッション開始すること、プロンプトを具体化して反復を減らすこと、類似タスクをバッチ化することなどを推奨しています。
  • 高度な節約として、関連部分のみ抽出、繰り返し用のプロンプトテンプレ化、DeepLやGoogleのような外部ツール活用、使用パターンのモニタリング、Power Stackによる自動化を挙げています。
  • タスク別に「最適化なし」と「最適化あり」のクレジット差を示し、例として簡単なQ&Aは100%削減、ブログ投稿や研究、Webアプリなどで40〜65%程度の節約を見込めるとしています。

The 3 Modes of Manus AI

Mode Cost Best For
Chat Mode FREE (0 credits) Q&A, translations, brainstorming
Standard ~40-60% less Blog posts, summaries, basic code
Max Full price Complex apps, multi-step research

The #1 mistake: Using Max mode for everything. 60%+ of tasks work perfectly on Standard or Chat Mode.

Decision Tree: Which Mode to Use?

Is it a simple question/translation/brainstorm?
  → YES → Chat Mode (FREE)
  → NO → Does it need web browsing or file creation?
    → NO → Standard Mode (save 40-60%)
    → YES → Does it need multiple complex steps?
      → NO → Standard Mode
      → YES → Max Mode (full price, full power)
