Multiagent Workflow using CrewAI and Ollama

# はじめに

AIエージェントは、自律的にまたは最小限の支援でタスクを実行できるソフトウェアツールです。これらは人工知能を使用して意思決定を行い、行動し、自分の周囲や他のシステムと対話します。以下に、これらのエージェントの主な特徴を挙げます：

1. **自律性**: 常に人間からの指示を必要とせずに、自律的に作業を行います。一度何をすべきか理解すれば、そのタスクを処理できます。
2. **意思決定**: 特定のルールやAIモデルを使用して選択を行います。これは、選択肢を評価し、最適なものを選ぶことを意味します。
3. **学習**: AIエージェントは時間の経過とともに学習します。機械学習を使用して過去の経験から学び、新しい状況に適応して作業の質を向上させます。
4. **対話**: 人間、他のエージェント、またはシステムと対話することができます。これには、人間の言語を理解して使用すること、データを共有すること、または共同でタスクを実行することが含まれます。
5. **専門化**: 特定の仕事や専門分野を持つことができます。例えば、ウェブブラウジング用に設計されたものもあれば、データベースタスクを処理したり、複雑な計算を行ったり、画像を作成したりするものもあります。
6. **目標志向**: 特定の目標や目的を持っています。これらの目標を達成するために一連の行動を取り、選択を行います。

要するに、AIエージェントは非常に役立ちます。単純で反復的なタスクから複雑な問題の解決まで、さまざまな業界やアプリケーションで利用できます。

これらの特徴が設定された目標に向かって連携して動作する様子を想像してください。タスクは特定の順序で、または階層的に実行され、エージェントがチームのように協力して働きます。これにより、複雑な問題の解決方法が変わり、効率的かつ効果的になります。これが、CrewAIフレームワークのコンセプトです。

# CrewAIとは？

CrewAIは、ロールプレイングゲームのAIキャラクターが協力して動作するのを助ける新しいシステムです。これにより、AIキャラクターがより賢くなり、複雑なタスクを共同で遂行できるようになります。

# コアコンセプト — CrewAI

1. **Agents**: これは、タスクを実行し、意思決定を行い、他のエージェントと対話する個別のユニットです。エージェントは、単純な検索機能から、他のチェーンやAPIを利用する複雑なタスクまで、様々な***Tools***を使用できます。
2. **Tasks**: タスクは、AIキャラクターが実行する必要のある作業です。タスクには、どのキャラクターが実行するか、必要なツールは何かなどの詳細を含めることができます。
3. **Crew**: クルーとは、特定の役割を持つエージェントが集まり、共通の目標を達成するために協力して働くグループです。クルーの設定には、エージェントを組み合わせ、彼らのタスクを決定し、タスクの順序を決めることが含まれます。

この記事では、CrewAIプラットフォームを使用する例を紹介します。

# Ollamaとは？

[Ollama](https://ollama.ai/)は、コンピュータから直接、大規模言語モデル（LLM）を使用、作成、共有できる無料のアプリです。MacOS、Linux、Windowsで動作します。

Ollamaのライブラリから多くのLLMを選ぶことができ、1つのコマンドでダウンロードが可能です。その後、さらに1つのコマンドで使用できます。これはターミナルウィンドウを頻繁に使用する人にとって非常に便利です。ブラウザを開かずにヘルプを見つけることができます。

# Ollamaを使用する理由

Ollamaが有用なツールである理由は次のとおりです：

- **使いやすさ**: Ollamaのセットアップは簡単で、機械学習の専門知識がなくても使用できます。
- **コスト削減**: モデルをコンピュータ上で実行するため、クラウドサービスの料金を支払う必要がありません。
- **プライバシー保護**: Ollamaはすべてのデータをコンピュータ上で処理します。これによりプライバシーが保護されます。
- **汎用性**: OllamaはPythonだけでなく、ウェブサイトの作成など多くのタスクに柔軟に対応できます。

# OllamaでLLMを選ぶ

デフォルトでは、CrewAIはLLMとしてOpenAIモデルを使用します。最高のパフォーマンスを得るためには、GPT-4またはコストが少し低いGPT-3.5を使用することを検討してください。これらのモデルはAIエージェントにとって重要です。

この例では、Meta Llama 3を使用します。これは現在利用可能な最高の無料LLMです。Meta Inc.によって作成され、8Bおよび70Bバージョン（プリトレーニング済みまたはインストラクションチューニング済み）が提供されています。

Meta Llama 3モデルはチャットアプリケーション向けにファインチューニングおよび最適化されており、他の多くの無料チャットモデルよりも優れた性能を発揮します。

# **コード実装**

**必要な依存関係のインストール**

•	Ollama（Windows）

OllamaのWebサイトにアクセスし、.exeファイルをダウンロードしてください：[https://ollama.com](https://ollama.com/)

![https://miro.medium.com/v2/resize:fit:560/0*hFA085olStz986kc.png](https://miro.medium.com/v2/resize:fit:560/0*hFA085olStz986kc.png)

Ollamaをダウンロードし、Windowsにインストールします。デフォルトのモデル保存パスは以下の通りです：

```
C:\\\\Users\\\\your_user\\\\.ollama

```

しかし、C:パーティションの空き容量が限られている場合、別のディレクトリに変更することをお勧めします。例えば、D:パーティションがある場合、以下の手順に従ってください：

1. デスクトップのコンピュータアイコンを右クリックします。
2. **プロパティ**を選択し、**システムの詳細設定**に移動します。
3. **環境変数**をクリックします。
4. **ユーザー環境変数**で、モデルを保存する予定のディレクトリの絶対パスを入力します。例：

```
D:\\\\your_model_directory

```

インストールが完了すると、WindowsのタスクバーにOllamaアイコンが表示されます。プログラムが自動的に起動しない場合は、Windowsプログラムで検索し、そこから起動してください。

```

Content Writer Agent（コンテンツを記述するエージェント）

- **Human Input**: (オプション) タスクの終了時に人間のフィードバックが必要であることを示し、人間の監督が必要なタスクに役立ちます。

### プランナータスクの作成

```
plan = Task(
    description=(
        "1\. Prioritize the latest trends, key players, "
            "and noteworthy news on {topic}.\\n"
        "2\. Identify the target audience, considering "
            "their interests and pain points.\\n"
        "3\. Develop a detailed content outline including "
            "an introduction, key points, and a call to action.\\n"
        "4\. Include SEO keywords and relevant data or sources."
    ),
    expected_output="A comprehensive content plan document "
        "with an outline, audience analysis, "
        "SEO keywords, and resources.",
    agent=planner,
)
```

Create Writer Task（ライタータスクの作成）

```
write = Task(
    description=(
        "1\. Use the content plan to craft a compelling "
            "blog post on {topic}.\\n"
        "2\. Incorporate SEO keywords naturally.\\n"
  "3\. Sections/Subtitles are properly named "
            "in an engaging manner.\\n"
        "4\. Ensure the post is structured with an "
            "engaging introduction, insightful body, "
            "and a summarizing conclusion.\\n"
        "5\. Proofread for grammatical errors and "
            "alignment with the brand's voice.\\n"
    ),
    expected_output="A well-written blog post "
        "in markdown format, ready for publication, "
        "each section should have 2 or 3 paragraphs.",
    agent=writer,
)
```

Create Editor Task（編集タスクの作成）

```
edit = Task(
    description=("Proofread the given blog post for "
                 "grammatical errors and "
                 "alignment with the brand's voice."),
    expected_output="A well-written blog post in markdown format, "
                    "ready for publication, "
                    "each section should have 2 or 3 paragraphs.",
    agent=editor
)
```

以下のように複数行の文字列を使用するメリットは：

```
varname = "line 1 of text"
          "line 2 of text"
```

トリプルクオートのドキュメント文字列と比較して：

```
varname = """line 1 of text
             line 2 of text
          """
```

改行文字や余分な空白が追加されないため、LLMに渡す際により良い形式になります。

## **Crewの作成手順**

1.	**エージェントの作成**: エージェントを作成します。

2.	**タスクの割り当て**: エージェントに実行するタスクを渡します。

**注意**: この簡単な例では、タスクは順次実行されます（つまり、タスクは互いに依存しています）。したがって、リスト内のタスクの順序が重要です。

verbose=2は実行のすべてのログを表示することを可能にします。

```
crew = Crew(
    agents=\[planner, writer, editor\],
    tasks=\[plan, write, edit\],
    verbose=2
)
```

## クルーを実行する

```
inputs = {"topic":"Comparative study of LangGraph, Autogen and Crewai for building multi-agent system."}

Comparative Study of LangGraph, Autogen and Crewai for Building Multi-Agent Systems
======================================================

In recent years, multi-agent systems have gained significant attention across various fields such as artificial intelligence (AI), robotics, and logistics. These complex systems involve multiple intelligent agents interacting with each other to achieve a common goal. The choice of technology plays a crucial role in building successful multi-agent systems. In this article, we will conduct a comparative study of LangGraph, Autogen, and Crewai, three prominent technologies used for building multi-agent systems.

\*\*Introduction\*\*
\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-

A multi-agent system (MAS) is defined as a complex system consisting of multiple intelligent agents interacting with each other to achieve a common goal. The importance of MAS lies in its ability to model real-world systems where multiple autonomous entities interact and adapt to changing environments. LangGraph, Autogen, and Crewai are three technologies that have gained significant attention in the field of multi-agent system building.
