Why Portkey + Arize Phoenix?

Arize Phoenix brings observability to LLM workflows with tracing, prompt debugging, and performance monitoring.

Thanks to Phoenix’s OpenInference instrumentation, Portkey can emit structured traces automatically — no extra setup needed. This gives you clear visibility into every LLM call, making it easier to debug and improve your app.

AI Gateway Features

  • 1600+ LLM Providers: Single API for OpenAI, Anthropic, AWS Bedrock, and more
  • Advanced Routing: Fallbacks, load balancing, conditional routing
  • Cost Optimization: Semantic caching, request
  • Security: PII detection, content filtering, compliance controls

Built-in Observability

  • 40+ Key Metrics: Cost, latency, tokens, error rates
  • Detailed Logs & Traces: Request/response bodies and custom tracing
  • Custom Metadata: Attach custom metadata to your requests
  • Custom Alerts: Real-time monitoring and notifications

With this integration, you can route LLM traffic through Portkey and gain deep observability in Arize Phoenix—bringing together the best of gateway orchestration and ML observability.

​
Getting Started

​
Installation

Install the required packages to enable Arize Phoenix integration with your Portkey deployment:

pip install portkey-ai openinference-instrumentation-portkey arize-otel

​
Setting up the Integration

1

Configure Arize Phoenix

First, set up the Arize OpenTelemetry configuration:

from arize.otel import register

# Configure Arize as your telemetry backend
tracer_provider = register(
    space_id="your-space-id",      # Found in Arize app settings
    api_key="your-api-key",        # Your Arize API key
    project_name="portkey-gateway" # Name your project
)
2

Enable Portkey Instrumentation

Initialize the Portkey instrumentor to format traces for Arize:

from openinference.instrumentation.portkey import PortkeyInstrumentor

# Enable instrumentation
PortkeyInstrumentor().instrument(tracer_provider=tracer_provider)
3

Configure Portkey AI Gateway

Set up Portkey with all its powerful features:

from portkey_ai import Portkey

# Initialize Portkey client
portkey = Portkey(
    api_key="your-portkey-api-key",  # Optional for self-hosted
    virtual_key="your-openai-virtual-key"  # Or use provider-specific virtual keys
)

response = portkey.chat.completions.create(
    model="gpt-4o-mini",
    messages=[{"role": "user", "content": "Explain machine learning"}]
)

print(response.choices[0].message.content)

​
Complete Integration Example

Here’s a complete working example that connects Portkey’s AI Gateway with Arize Phoenix for centralized monitoring:

import os
from openai import OpenAI
from portkey_ai import PORTKEY_GATEWAY_URL, createHeaders
from arize.otel import register  # OR from phoenix.otel import register

# configure the Phoenix tracer
from openinference.instrumentation.portkey import PortkeyInstrumentor

# Step 1: Configure Arize Phoenix
tracer_provider = register(
    space_id="your-space-id",
    api_key="your-arize-api-key",
    project_name="portkey-production"
)

# Step 2: Enable Portkey instrumentation
PortkeyInstrumentor().instrument(tracer_provider=tracer_provider)

# Step 3: Configure Portkey's Advanced AI Gateway
advanced_config = {
    "strategy": {
        "mode": "loadbalance"  # Distribute load across providers
    },

    },
    "request_timeout": 30000
}

# Initialize Portkey-powered client
client = OpenAI(
    api_key="not-needed",  # Virtual keys handle auth
    base_url=PORTKEY_GATEWAY_URL,
    default_headers=createHeaders(
        api_key=os.environ.get("PORTKEY_API_KEY"),
        config=advanced_config,
        metadata={

            "session_id": "session-456",
            "feature": "chat-assistant"
        }
    )
)

# Make requests through Portkey's AI Gateway
response = client.chat.completions.create(
    model="gpt-4o",  # Portkey handles provider routing
    messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Explain quantum computing in simple terms."}
    ],
