Installation & Setup

1. Install the required packages

   pip install -U crewai portkey-ai
   

2. Generate API Key

   Create a Portkey API key with optional budget/rate limits from the Portkey dashboard. You can also attach configurations for reliability, caching, and more to this key. More on this later.

3. Configure CrewAI with Portkey

   The integration is simple - you just need to update the LLM configuration in your CrewAI setup:

   from crewai import LLM
   from portkey_ai import createHeaders, PORTKEY_GATEWAY_URL
   
   # Create an LLM instance with Portkey integration
   gpt_llm = LLM(
       model="gpt-4o",
       base_url=PORTKEY_GATEWAY_URL,
       api_key="dummy",
       extra_headers=createHeaders(
           api_key="YOUR_PORTKEY_API_KEY",
           provider="@YOUR_LLM_PROVIDER",
           trace_id="unique-trace-id",               # Optional, for request tracing
       )
   )
   
   #Use them in your Crew Agents like this:
   
   	@agent
   	def lead_market_analyst(self) -> Agent:
   		return Agent(
   			config=self.agents_config['lead_market_analyst'],
   			verbose=True,
   			memory=False,
   			llm=gpt_llm
   		)
   
   

Production Features

1. Enhanced Observability

Portkey provides comprehensive observability for your CrewAI agents, helping you understand exactly what’s happening during each execution.

Traces

Traces provide a hierarchical view of your crew’s execution, showing the sequence of LLM calls, tool invocations, and state transitions.

# Add trace_id to enable hierarchical tracing in Portkey
portkey_llm = LLM(
    model="gpt-4o",
    base_url=PORTKEY_GATEWAY_URL,
    api_key="dummy",
    extra_headers=createHeaders(
        api_key="YOUR_PORTKEY_API_KEY",
        provider="@YOUR_OPENAI_PROVIDER",
        trace_id="unique-session-id"  # Add unique trace ID
    )
)

2. Reliability - Keep Your Crews Running Smoothly

When running crews in production, things can go wrong - API rate limits, network issues, or provider outages. Portkey’s reliability features ensure your agents keep running smoothly even when problems occur.

It’s simple to enable fallback in your CrewAI setup by using a Portkey Config:

from crewai import LLM
from portkey_ai import createHeaders, PORTKEY_GATEWAY_URL

# Create LLM with fallback configuration
portkey_llm = LLM(
    model="gpt-4o",
    max_tokens=1000,
    base_url=PORTKEY_GATEWAY_URL,
    api_key="dummy",
    extra_headers=createHeaders(
        api_key="YOUR_PORTKEY_API_KEY",
        config={
            "strategy": {
                "mode": "fallback"
            },
            "targets": [
                {
                    "provider": "openai",
                    "api_key": "YOUR_OPENAI_API_KEY",
                    "override_params": {"model": "gpt-4o"}
                },
                {
                    "provider": "anthropic",
                    "api_key": "YOUR_ANTHROPIC_API_KEY",
                    "override_params": {"model": "claude-3-opus-20240229"}
                }
            ]
        }
    )
)

# Use this LLM configuration with your agents

This configuration will automatically try Claude if the GPT-4o request fails, ensuring your crew can continue operating.

Automatic Retries

Handles temporary failures automatically. If an LLM call fails, Portkey will retry the same request for the specified number of times - perfect for rate limits or network blips.

Request Timeouts

Prevent your agents from hanging. Set timeouts to ensure you get responses (or can fail gracefully) within your required timeframes.

Conditional Routing

Send different requests to different providers. Route complex reasoning to GPT-4, creative tasks to Claude, and quick responses to Gemini based on your needs.

Fallbacks

Keep running even if your primary provider fails. Automatically switch to backup providers to maintain availability.

Load Balancing

Spread requests across multiple API keys or providers. Great for high-volume crew operations and staying within rate limits.

3. Prompting in CrewAI

Portkey’s Prompt Engineering Studio helps you create, manage, and optimize the prompts used in your CrewAI agents. Instead of hardcoding prompts or instructions, use Portkey’s prompt rendering API to dynamically fetch and apply your versioned prompts.

Manage prompts in Portkey's Prompt Library

Prompt Playground

Prompt Playground is a place to compare, test and deploy perfect prompts for your AI application. It’s where you experiment with different models, test variables, compare outputs, and refine your prompt engineering strategy before deploying to production. It allows you to:

1. Iteratively develop prompts before using them in your agents
2. Test prompts with different variables and models
3. Compare outputs between different prompt versions
4. Collaborate with team members on prompt development

This visual environment makes it easier to craft effective prompts for each step in your CrewAI agents’ workflow.

4. Guardrails for Safe Crews

Guardrails ensure your CrewAI agents operate safely and respond appropriately in all situations.

Why Use Guardrails?

CrewAI agents can experience various failure modes:

• Generating harmful or inappropriate content
• Leaking sensitive information like PII
• Hallucinating incorrect information
• Generating outputs in incorrect formats

Portkey’s guardrails add protections for both inputs and outputs.

Implementing Guardrails

from crewai import Agent, LLM
from portkey_ai import createHeaders, PORTKEY_GATEWAY_URL

# Create LLM with guardrails
portkey_llm = LLM(
    model="gpt-4o",
    base_url=PORTKEY_GATEWAY_URL,
    api_key="dummy",
    extra_headers=createHeaders(
        api_key="YOUR_PORTKEY_API_KEY",
        provider="@YOUR_OPENAI_PROVIDER",
        config={
            "input_guardrails": ["guardrails-id-xxx", "guardrails-id-yyy"],
            "output_guardrails": ["guardrails-id-zzz"]
        }
    )
)

# Create agent with guardrailed LLM
researcher = Agent(
    role="Senior Research Scientist",
    goal="Discover groundbreaking insights about the assigned topic",
    backstory="You are an expert researcher with deep domain knowledge.",
    verbose=True,
    llm=portkey_llm
)

Portkey’s guardrails can:

• Detect and redact PII in both inputs and outputs
• Filter harmful or inappropriate content
• Validate response formats against schemas
• Check for hallucinations against ground truth
• Apply custom business logic and rules

5. User Tracking with Metadata

Track individual users through your CrewAI agents using Portkey’s metadata system.

What is Metadata in Portkey?

Metadata allows you to associate custom data with each request, enabling filtering, segmentation, and analytics. The special _user field is specifically designed for user tracking.

from crewai import Agent, LLM
from portkey_ai import createHeaders, PORTKEY_GATEWAY_URL

# Configure LLM with user tracking
portkey_llm = LLM(
    model="gpt-4o",
    base_url=PORTKEY_GATEWAY_URL,
    api_key="dummy",
    extra_headers=createHeaders(
        api_key="YOUR_PORTKEY_API_KEY",
        provider="@YOUR_OPENAI_PROVIDER",
        metadata={
            "_user": "user_123",  # Special _user field for user analytics
            "user_tier": "premium",
            "user_company": "Acme Corp",
            "session_id": "abc-123"
        }
    )
)

# Create agent with tracked LLM
researcher = Agent(
    role="Senior Research Scientist",
    goal="Discover groundbreaking insights about the assigned topic",
    backstory="You are an expert researcher with deep domain knowledge.",
    verbose=True,
    llm=portkey_llm
)

Filter Analytics by User

With metadata in place, you can filter analytics by user and analyze performance metrics on a per-user basis:

Filter analytics by user

This enables:

• Per-user cost tracking and budgeting
• Personalized user analytics
• Team or organization-level metrics
• Environment-specific monitoring (staging vs. production)

6. Caching for Efficient Crews

Implement caching to make your CrewAI agents more efficient and cost-effective:

Simple Caching

from crewai import Agent, LLM
from portkey_ai import createHeaders, PORTKEY_GATEWAY_URL

# Configure LLM with simple caching
portkey_llm = LLM(
    model="gpt-4o",
    base_url=PORTKEY_GATEWAY_URL,
    api_key="dummy",
    extra_headers=createHeaders(
        api_key="YOUR_PORTKEY_API_KEY",
        provider="@YOUR_OPENAI_PROVIDER",
        config={
            "cache": {
                "mode": "simple"
            }
        }
    )
)

# Create agent with cached LLM
researcher = Agent(
    role="Senior Research Scientist",
    goal="Discover groundbreaking insights about the assigned topic",
    backstory="You are an expert researcher with deep domain knowledge.",
    verbose=True,
    llm=portkey_llm
)

Simple caching performs exact matches on input prompts, caching identical requests to avoid redundant model executions.

7. Model Interoperability

CrewAI supports multiple LLM providers, and Portkey extends this capability by providing access to over 200 LLMs through a unified interface. You can easily switch between different models without changing your core agent logic:

from crewai import Agent, LLM
from portkey_ai import createHeaders, PORTKEY_GATEWAY_URL

# Set up LLMs with different providers
openai_llm = LLM(
    model="gpt-4o",
    base_url=PORTKEY_GATEWAY_URL,
    api_key="dummy",
    extra_headers=createHeaders(
        api_key="YOUR_PORTKEY_API_KEY",
        provider="@YOUR_OPENAI_PROVIDER"
    )
)

anthropic_llm = LLM(
    model="claude-3-5-sonnet-latest",
    max_tokens=1000,
    base_url=PORTKEY_GATEWAY_URL,
    api_key="dummy",
    extra_headers=createHeaders(
        api_key="YOUR_PORTKEY_API_KEY",
        provider="@YOUR_ANTHROPIC_PROVIDER"
    )
)

# Choose which LLM to use for each agent based on your needs
researcher = Agent(
    role="Senior Research Scientist",
    goal="Discover groundbreaking insights about the assigned topic",
    backstory="You are an expert researcher with deep domain knowledge.",
    verbose=True,
    llm=openai_llm  # Use anthropic_llm for Anthropic
)

Portkey provides access to LLMs from providers including:

• OpenAI (GPT-4o, GPT-4 Turbo, etc.)
• Anthropic (Claude 3.5 Sonnet, Claude 3 Opus, etc.)
• Mistral AI (Mistral Large, Mistral Medium, etc.)
• Google Vertex AI (Gemini 1.5 Pro, etc.)
• Cohere (Command, Command-R, etc.)
• AWS Bedrock (Claude, Titan, etc.)
• Local/Private Models

Supported Providers

Set Up Enterprise Governance for CrewAI

Why Enterprise Governance? If you are using CrewAI inside your organization, you need to consider several governance aspects:

• Cost Management: Controlling and tracking AI spending across teams
• Access Control: Managing which teams can use specific models
• Usage Analytics: Understanding how AI is being used across the organization
• Security & Compliance: Maintaining enterprise security standards
• Reliability: Ensuring consistent service across all users

Portkey adds a comprehensive governance layer to address these enterprise needs. Let’s implement these controls step by step.

1. Create LLM Integrations

   Go to Integrations in the Portkey App, choose your LLM and connect to it. Save and copy the generated provider ID.

2. Create Default Config

   Configs in Portkey define how your requests are routed, with features like advanced routing, fallbacks, and retries.

   To create your config:

   1. Go to Configs in Portkey dashboard
   2. Create new config with:
      {
          "provider":"@YOUR_PROVIDER_FROM_STEP1",
         	"override_params": {
            "model": "gpt-4o" // Your preferred model name
          }
      }
      

   3. Save and note the Config name for the next step

   
3. Configure Portkey API Key

   Now create a Portkey API key and attach the config you created in Step 2:

   1. Go to API Keys in Portkey and Create new API key
   2. Select your config from Step 2
   3. Generate and save your API key

   
4. Connect to CrewAI

   After setting up your Portkey API key with the attached config, connect it to your CrewAI agents:

   from crewai import Agent, LLM
   from portkey_ai import PORTKEY_GATEWAY_URL
   
   # Configure LLM with your API key
   portkey_llm = LLM(
       model="gpt-4o",
       base_url=PORTKEY_GATEWAY_URL,
       api_key="YOUR_PORTKEY_API_KEY"
   )
   
   # Create agent with Portkey-enabled LLM
   researcher = Agent(
       role="Senior Research Scientist",
       goal="Discover groundbreaking insights about the assigned topic",
       backstory="You are an expert researcher with deep domain knowledge.",
       verbose=True,
       llm=portkey_llm
   )
   

Step 1: Implement Budget Controls & Rate Limits

Step 1: Implement Budget Controls & Rate Limits

Enable granular control over LLM access at the team/department level. This helps you:

• Set up budget limits
• Prevent unexpected usage spikes using Rate limits
• Track departmental spending

Setting Up Department-Specific Controls:

1. Navigate to Integrations in Portkey dashboard and create a new LLM integration
2. Provision this integration for each department with budget limits and rate limits
3. Configure department-specific limits

Step 2: Define Model Access Rules

Step 2: Define Model Access Rules

As your AI usage scales, controlling which teams can access specific models becomes crucial. Portkey Configs provide this control layer with features like:

Access Control Features:

• Model Restrictions: Limit access to specific models
• Data Protection: Implement guardrails for sensitive data
• Reliability Controls: Add fallbacks and retry logic

Example Configuration:

Here’s a basic configuration to route requests to OpenAI, specifically using GPT-4o:

{
	"strategy": {
		"mode": "single"
	},
	"targets": [
		{
			"provider":"@YOUR_OPENAI_PROVIDER",
			"override_params": {
				"model": "gpt-4o"
			}
		}
	]
}

Create your config on the Configs page in your Portkey dashboard.

Configs can be updated anytime to adjust controls without affecting running applications.

Step 3: Implement Access Controls

Step 3: Implement Access Controls

Create User-specific API keys that automatically:

• Track usage per user/team with metadata
• Apply appropriate configs to route requests
• Collect relevant metadata to filter logs
• Enforce access permissions

Create API keys through:

• Portkey App
• API Key Management API

Example using Python SDK:

from portkey_ai import Portkey

portkey = Portkey(api_key="YOUR_ADMIN_API_KEY")

api_key = portkey.api_keys.create(
    name="engineering-team",
    type="organisation",
    workspace_id="YOUR_WORKSPACE_ID",
    defaults={
        "config_id": "your-config-id",
        "metadata": {
            "environment": "production",
            "department": "engineering"
        }
    },
    scopes=["logs.view", "configs.read"]
)

For detailed key management instructions, see our API Keys documentation.
