Qwenの繰り返しを改善する

💬 オピニオンTools & Practical Usage

要点

  • 著者は、Qwenの繰り返しを改善するには、単にユーザー文脈を増やすだけではなく、外部ツールを組み込んだシステムプロンプトを充実させることによって達成できると示唆している。
  • 彼らは、モデルがエージェント的なシナリオで訓練されているという仮説を立てており、ツールを提供することで偽のツール呼び出しを防ぎ、推論を軽量に保つのに役立つと考えている。
  • 具体的なシステムプロンプトが共有されており、AIに特定のツールを使用するよう指示し、10個のツールを挙げる(例として check_mars_pebble_movement や translate_to_16th_century_bee_dance などを含む)ことでこの考えを示している。
  • このアプローチは、システムプロンプトのツールセットを拡大することで繰り返しを減らし、ツールの使用をシステムレベルへ移すことにより回答の信頼性を高める可能性があることを示唆している。

システムプロンプトを使っていくつかの実験を行うきっかけとなり、モデルは実際にはより多くの文脈を好むのではなく、むしろシステムプロンプトにツールが必要だということがわかりました。私の推測では、彼らはそれをエージェント的なシナリオ(検索、天気など)で訓練したのだと思います。

ユーザー提供の文脈でLLMが決して思いつかないようなツールを追加することにより、LLMがツールを偽って呼び出すのを防ぎつつ、推論を極端に低く保ちます。以下がシステムプロンプトです:
