Introduction

The OpenAI Agents SDK is a powerful framework for building agent-based AI systems that can solve complex tasks through planning and tool use. By integrating it with Ollama, we can run these agents locally, improving privacy, reducing latency, and eliminating API costs.

Understanding the Components

What is the OpenAI Agents SDK?

The OpenAI Agents SDK (agents) is a framework that simplifies the development of AI agents. It provides:

• A structured approach for defining agent behaviors
• Built-in support for tool usage and planning
• Session management for multi-turn conversations
• Memory and state persistence

At its core, this SDK formalizes the agent pattern that emerged from the broader LLM community, giving developers a standard way to implement agents that can plan, reason, and execute complex tasks.

What is Ollama?

Ollama is an open-source framework for running large language models (LLMs) locally. Key features include:

• Easy installation and model management
• Compatible API endpoints that mimic OpenAI's API structure
• Support for many open-source models (Llama, Mistral, etc.)
• Custom model creation and fine-tuning

Why Integrate Them?

Integration provides several benefits:

1. Data Privacy: All data stays on your local machine
2. Cost Efficiency: No pay-per-token API costs
3. Customization: Fine-tune models for specific use cases
4. Network Independence: Agents function without internet access
5. Reduced Latency: Eliminate network roundtrips

Setting Up Your Environment

Step 1: Install Ollama

First, install Ollama following the instructions for your operating system:

For macOS and Linux:

bashCopy
1curl -fsSL https://ollama.ai/install.sh | sh

For Windows:

Download the installer from Ollama's website.

Step 2: Download a Model

Pull a capable model that will power your agent. For this guide, we'll use Mistral:

bashCopy
1ollama pull mistral

Verify that Ollama is working by running:

bashCopy
1ollama run mistral "Hello, are you running correctly?"

You should see a response generated by the model.

Step 3: Install the OpenAI Agents SDK

Clone the repository and install the package:

bashCopy
1git clone https://github.com/openai/openai-agents-python.git
2cd openai-agents-python
3pip install -e .

This installs the package in development mode, allowing you to modify the code if needed.

Step 4: Set Up Required Dependencies

Install additional dependencies:

bashCopy
1pip install requests python-dotenv pydantic

Integrating Ollama with OpenAI Agents SDK

The OpenAI Agents SDK uses the OpenAI Python client underneath. We need to create a custom client that directs requests to Ollama instead of OpenAI's servers.

Step 1: Create a Custom Client

Create a file named ollama_client.py:

pythonCopy
1import os
2from openai import OpenAI
3
4class OllamaClient(OpenAI):
5    """Custom OpenAI client that routes requests to Ollama."""
6
7    def __init__(self, model_name="mistral", **kwargs):
8        # Configure to use Ollama's endpoint
9        kwargs["base_url"] = "http://localhost:11434/v1"
10
11        # Ollama doesn't require an API key but the client expects one
12        kwargs["api_key"] = "ollama-placeholder-key"
13
14        super().__init__(**kwargs)
15        self.model_name = model_name
16        
17        # Check if the model exists
18        print(f"Using Ollama model: {model_name}")
19
20    def create_completion(self, *args, **kwargs):
21        # Override model name if not explicitly provided
22        if "model" not in kwargs:
23            kwargs["model"] = self.model_name
24
25        return super().create_completion(*args, **kwargs)
26
27    def create_chat_completion(self, *args, **kwargs):
28        # Override model name if not explicitly provided
29        if "model" not in kwargs:
30            kwargs["model"] = self.model_name
31
32        return super().create_chat_completion(*args, **kwargs)
33        
34    # These methods are needed for compatibility with agents library
35    def completion(self, prompt, **kwargs):
36        if "model" not in kwargs:
37            kwargs["model"] = self.model_name
38        return self.completions.create(prompt=prompt, **kwargs)
39        
40    def chat_completion(self, messages, **kwargs):
41        if "model" not in kwargs:
42            kwargs["model"] = self.model_name
43        return self.chat.completions.create(messages=messages, **kwargs)

Step 2: Create an Adapter for OpenAI Agents SDK

Now we'll create an adapter that makes the OpenAI Agents SDK compatible with our Ollama client. Create a file named agent_adapter.py:

pythonCopy
1from ollama_client import OllamaClient
2from openai.types.chat import ChatCompletion, ChatCompletionMessage
3import agents.agent as agent_module
4from agents.agent import Agent
5from agents.run import Runner, RunConfig
6from agents.models import _openai_shared
7import json
8import logging
9
10# Configure logging
11logging.basicConfig(level=logging.INFO, format='%(asctime)s - %(name)s - %(levelname)s - %(message)s')
12logger = logging.getLogger(__name__)
13
14# Set placeholder OpenAI API key to avoid initialization errors
15_openai_shared.set_default_openai_key("placeholder-key")
16
17# Store original init for Agent class
18original_init = Agent.__init__
19
20def patched_init(self, *args, **kwargs):
21    """Replace the model with OllamaClient if not provided."""
22    if "model" not in kwargs:
23        kwargs["model"] = OllamaClient(model_name="mistral")
24    original_init(self, *args, **kwargs)
25
26# Apply the patched init
27Agent.__init__ = patched_init
28
29
30# Class for a structured tool call
31class ToolCall:
32    def __init__(self, name, inputs=None):
33        self.name = name
34        self.inputs = inputs or {}
35
36# Define a response class that matches what main.py expects
37class AgentResponse:
38    def __init__(self, result):
39        # Extract the message from the final output
40        if hasattr(result, 'final_output'):
41            if isinstance(result.final_output, str):
42                self.message = result.final_output
43            else:
44                self.message = str(result.final_output)
45        else:
46            self.message = "I'm sorry, I couldn't process that request."
47

63                                inputs = tool_call.get('inputs', {})
64                                self.tool_calls.append(ToolCall(name, inputs))

Building a Document Analysis Agent

Let's build a practical agent that analyzes documents, extracts key information, and answers questions about the content.

Step 1: Create Document Memory

First, let's create a simple document memory system to store and retrieve analyzed documents. Create a file named document_memory.py:

pythonCopy
1import os
2import json
3import hashlib
4from typing import Dict, List, Optional
5
6class DocumentMemory:
7    """Simple document storage system for the agent."""
8    
9    def __init__(self, storage_dir: str = "./document_memory"):
10        self.storage_dir = storage_dir
11        os.makedirs(storage_dir, exist_ok=True)
12        
13        self.index_file = os.path.join(storage_dir, "index.json")
14        self.document_index = self._load_index()
15    
16    def _load_index(self) -> Dict:
17        """Load document index from disk."""
18        if os.path.exists(self.index_file):
19            with open(self.index_file, 'r') as f:
20                return json.load(f)
21        return {"documents": {}}
22    
23    def _save_index(self):
24        """Save document index to disk."""
25        with open(self.index_file, 'w') as f:
26            json.dump(self.document_index, f, indent=2)
27    
28    def _generate_doc_id(self, url: str) -> str:
29        """Generate a unique ID for a document based on its URL."""
30        return hashlib.md5(url.encode()).hexdigest()
31    
32    def store_document(self, url: str, content: str, metadata: Optional[Dict] = None) -> str:
33        """Store a document and return its ID."""
34        doc_id = self._generate_doc_id(url)
35        doc_path = os.path.join(self.storage_dir, f"{doc_id}.txt")
36        
37        # Store document content
38        with open(doc_path, 'w') as f:
39            f.write(content)
40        
41        # Update index
42        self.document_index["documents"][doc_id] = {
43            "url": url,
44            "path": doc_path,
45            "metadata": metadata or {}
46        }
47        
48        self._save_index()
49        return doc_id
50    
51    def get_document(self, doc_id: str) -> Optional[Dict]:
52        """Retrieve a document by ID."""
53        if doc_id not in self.document_index["documents"]:
54            return None
55        
56        doc_info = self.document_index["documents"][doc_id]
57        
58        try:
59            with open(doc_info["path"], 'r') as f:
60                content = f.read()
61            return {
62                "id": doc_id,
63                "url": doc_info["url"],
64                "content": content,
65                "metadata": doc_info["metadata"]
66            }
67        except Exception as e:
68            print(f"Error retrieving document {doc_id}: {e}")
69            return None
70    
71    def get_document_by_url(self, url: str) -> Optional[Dict]:
72        """Find and retrieve a document by URL."""
73        doc_id = self._generate_doc_id(url)
74        return self.get_document(doc_id)
75    
76    def list_documents(self) -> List[Dict]:
77        """List all stored documents."""
78        return [
79            {"id": doc_id, "url": info["url"], "metadata": info["metadata"]}
80            for doc_id, info in self.document_index["documents"].items()
81        ]

Step 2: Define the Agent's Tools

Create a file named document_agent.py to implement the document analysis agent with its tools:

14You: Please analyze the article at https://en.wikipedia.org/wiki/Artificial_intelligence and tell me when AI was first developed as a concept.
15
16Processing...
17
18Agent: Based on my analysis of the Wikipedia article on Artificial Intelligence, the concept of AI has historical roots that go back centuries, but the formal academic field of AI was founded in 1956.
19
20According to the article, the workshop at Dartmouth College in the summer of 1956 is widely considered the founding event of artificial intelligence as a field. This was when John McCarthy coined the term "artificial intelligence" as the topic of the Dartmouth Conference.
21
22However, the concept of artificial beings with intelligence appeared much earlier in history:
23
24- Ancient Greek myths mentioned mechanical men designed to mimic human functions
25- Philosophers like Aristotle described mechanical reasoning in syllogisms
26- In the 13th century, Ramon Llull developed logical machines
27- In the 17th century, René Descartes, Thomas Hobbes, and Gottfried Leibniz explored mechanical reasoning
28- In the 19th century, Charles Babbage and Ada Lovelace contemplated programmable mechanical calculating devices
29
30The article indicates that the modern field of AI research officially began at that 1956 workshop organized by John McCarthy, Marvin Minsky, Claude Shannon, and Nathaniel Rochester.

32🛠️  Tools Used:
33  • fetch_document(url='https://en.wikipedia.org/wiki/Artificial_intelligence')
34  • search_document(query='when was AI first developed concept history')

Troubleshooting

Here are some common issues you might encounter and how to fix them:

1. Model Issues

Problem: The model generates poor responses, hallucinates, or fails to use tools properly.

Solution:

• Try a more capable model like llama3 or mixtral
• Check if your prompts are clear and well-formatted
• Reduce the complexity of your tools
• Add more explicit instructions in the agent's system prompt

You can pull a more capable model with:

bashCopy
1ollama pull llama3

Then update your client:

pythonCopy
1client = OllamaClient(model_name="llama3")

2. Context Length Issues

Problem: The model returns incomplete responses or fails when processing long documents.

Solution:

• Implement chunking for document text (we've already limited to 2000 characters in our tools)
• Use models with larger context windows if available (like Llama 3 or Mixtral)
• Break down complex tasks into smaller subtasks

3. API Compatibility Issues

Problem: Some OpenAI client functions aren't supported by Ollama.

Solution:

• Our adapted client handles the most common method differences
• If you encounter unsupported features, add similar wrapper methods to OllamaClient class
• Check Ollama's API documentation for compatible endpoints

Conclusion

In this guide, we've explored how to integrate the OpenAI Agents SDK with Ollama to create a powerful document analysis agent that runs entirely on local infrastructure. This approach combines the best of both worlds: the structured agent framework from OpenAI with the privacy and cost benefits of local inference through Ollama.

Key takeaways:

1. Architecture: We've created a layered architecture with:

   • Ollama providing the LLM inference capability
   • A custom client adapter connecting Ollama to the OpenAI interface
   • The OpenAI Agents SDK providing the agent framework
   • Custom tools for document analysis and memory

2. Implementation: We've built a complete document analysis agent with:

   • Document fetching and parsing
   • Information extraction
   • Document search
   • Persistent document storage

3. Benefits:

   • Complete data privacy
   • No ongoing API costs
   • Customizable to specific use cases
   • Works offline

4. Limitations and Mitigations:

   • Model quality limitations (mitigated by using more capable models)
   • Context length constraints (mitigated with our chunking approach)
   • API compatibility gaps (mitigated with our custom client)

This integration demonstrates how organizations can leverage the power of advanced AI agent frameworks while maintaining control over their data and infrastructure. The result is a flexible, extensible system that can be adapted to many different use cases beyond document analysis.

By building on this foundation, you can create specialized agents for various domains while keeping all processing local and secure.
