Orq.ai Documentation - AI Gateway & LLM Collaboration Platform

AI Router

Route your LLM calls through the AI Router with a single base URL change. Zero vendor lock-in: always run on the best model at the lowest cost for your use case.

Observability

Instrument your code with OpenTelemetry to capture traces, logs, and metrics for every LLM call, agent step, and tool use.

AI Router

Overview

Microsoft AutoGen is a framework for building multi-agent conversational AI systems with collaborative problem-solving through automated agent interactions. By connecting AutoGen to Orq.ai’s AI Router, you get access to 300+ models for your multi-agent workflows with a single configuration change.

Key Benefits

Orq.ai’s AI Router enhances your AutoGen applications with:

Complete Observability

Track every agent conversation, tool use, and multi-agent interaction

Built-in Reliability

Automatic fallbacks, retries, and load balancing for production resilience

Cost Optimization

Real-time cost tracking and spend management across all your AI operations

Multi-Provider Access

Access 300+ LLMs and 20+ providers through a single, unified integration

Prerequisites

Before integrating AutoGen with Orq.ai, ensure you have:

An Orq.ai account and API Key
Python 3.10 or higher

To setup your API key, see API keys & Endpoints.

Installation

pip install "autogen-agentchat" "autogen-ext[openai]"

Configuration

Configure AutoGen to use Orq.ai’s AI Router via OpenAIChatCompletionClient with a custom base_url:

Python

import os
from autogen_ext.models.openai import OpenAIChatCompletionClient

model_client = OpenAIChatCompletionClient(
    model="gpt-4o",
    base_url="https://api.orq.ai/v2/router",
    api_key=os.getenv("ORQ_API_KEY"),
    model_info={
        "vision": False,
        "function_calling": True,
        "json_output": True,
        "family": "unknown",
        "structured_output": True,
    },
)

base_url: https://api.orq.ai/v2/router

The model_info dict is required when using a custom base_url so AutoGen knows the model’s capabilities.

Basic Agent Example

Python

import asyncio
import os
from autogen_agentchat.agents import AssistantAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient

async def main():
    model_client = OpenAIChatCompletionClient(
        model="gpt-4o",
        base_url="https://api.orq.ai/v2/router",
        api_key=os.getenv("ORQ_API_KEY"),
        model_info={
            "vision": False,
            "function_calling": True,
            "json_output": True,
            "family": "unknown",
            "structured_output": True,
        },
    )

    agent = AssistantAgent(
        name="assistant",
        model_client=model_client,
        system_message="You are a helpful assistant.",
    )

    result = await agent.run(task="What is quantum computing?")
    print(result.messages[-1].content)
    await model_client.close()

asyncio.run(main())

Multi-Agent Team

Orchestrate multiple specialized agents with RoundRobinGroupChat:

Python

import asyncio
import os
from autogen_agentchat.agents import AssistantAgent
from autogen_agentchat.teams import RoundRobinGroupChat
from autogen_agentchat.conditions import MaxMessageTermination
from autogen_ext.models.openai import OpenAIChatCompletionClient

async def main():
    model_client = OpenAIChatCompletionClient(
        model="gpt-4o",
        base_url="https://api.orq.ai/v2/router",
        api_key=os.getenv("ORQ_API_KEY"),
        model_info={
            "vision": False,
            "function_calling": True,
            "json_output": True,
            "family": "unknown",
            "structured_output": True,
        },
    )

    researcher = AssistantAgent(
        name="researcher",
        model_client=model_client,
        system_message="You research topics and provide key facts.",
    )

    writer = AssistantAgent(
        name="writer",
        model_client=model_client,
        system_message="You write clear summaries based on research.",
    )

    team = RoundRobinGroupChat(
        participants=[researcher, writer],
        termination_condition=MaxMessageTermination(max_messages=2),
    )

    result = await team.run(task="Research and summarize what LLMs are.")
    print(result.messages[-1].content)
    await model_client.close()

asyncio.run(main())

Model Selection

With Orq.ai, you can use any supported model from 20+ providers:

Python

import os
from autogen_ext.models.openai import OpenAIChatCompletionClient

model_info = {
    "vision": False,
    "function_calling": True,
    "json_output": True,
    "family": "unknown",
    "structured_output": True,
}

# Use Claude
claude_client = OpenAIChatCompletionClient(
    model="claude-sonnet-4-5-20250929",
    base_url="https://api.orq.ai/v2/router",
    api_key=os.getenv("ORQ_API_KEY"),
    model_info=model_info,
)

# Use Gemini
gemini_client = OpenAIChatCompletionClient(
    model="gemini-2.5-flash",
    base_url="https://api.orq.ai/v2/router",
    api_key=os.getenv("ORQ_API_KEY"),
    model_info=model_info,
)

# Use Groq
groq_client = OpenAIChatCompletionClient(
    model="groq/llama-3.3-70b-versatile",
    base_url="https://api.orq.ai/v2/router",
    api_key=os.getenv("ORQ_API_KEY"),
    model_info=model_info,
)

Observability

Getting Started

Microsoft AutoGen enables sophisticated multi-agent conversations and collaborative AI systems. Tracing AutoGen with Orq.ai provides deep insights into agent interactions, conversation flows, tool usage, and multi-agent coordination patterns to optimize your conversational AI applications.

Prerequisites

Before you begin, ensure you have:

An Orq.ai account and API Key
Python 3.8+
Microsoft AutoGen installed in your project
OpenAI API key (or other LLM provider credentials)

Install Dependencies

# Core AutoGen and OpenTelemetry packages
pip install pyautogen opentelemetry-sdk opentelemetry-exporter-otlp-proto-http

# LLM providers
pip install openai

Configure Orq.ai

Set up your environment variables to connect to Orq.ai’s OpenTelemetry collector: Unix/Linux/macOS:

export OTEL_EXPORTER_OTLP_ENDPOINT="https://api.orq.ai/v2/otel"
export OTEL_EXPORTER_OTLP_HEADERS="Authorization=Bearer <ORQ_API_KEY>"
export OTEL_RESOURCE_ATTRIBUTES="service.name=autogen-app,service.version=1.0.0"
export OPENAI_API_KEY="<YOUR_OPENAI_API_KEY>"

Windows (PowerShell):

$env:OTEL_EXPORTER_OTLP_ENDPOINT = "https://api.orq.ai/v2/otel"
$env:OTEL_EXPORTER_OTLP_HEADERS = "Authorization=Bearer <ORQ_API_KEY>"
$env:OTEL_RESOURCE_ATTRIBUTES = "service.name=autogen-app,service.version=1.0.0"
$env:OPENAI_API_KEY = "<YOUR_OPENAI_API_KEY>"

Using .env file:

OTEL_EXPORTER_OTLP_ENDPOINT=https://api.orq.ai/v2/otel
OTEL_EXPORTER_OTLP_HEADERS=Authorization=Bearer <ORQ_API_KEY>
OTEL_RESOURCE_ATTRIBUTES=service.name=autogen-app,service.version=1.0.0
OPENAI_API_KEY=<YOUR_OPENAI_API_KEY>

Integration

AutoGen has built-in OpenTelemetry support. Configure the tracer provider and pass it to the AutoGen runtime.

Set up OpenTelemetry tracing in your application:

import os
import autogen
from opentelemetry import trace
from opentelemetry.exporter.otlp.proto.http.trace_exporter import OTLPSpanExporter
from opentelemetry.sdk.resources import Resource
from opentelemetry.sdk.trace import TracerProvider
from opentelemetry.sdk.trace.export import BatchSpanProcessor

# Configure tracer provider
tracer_provider = TracerProvider(
    resource=Resource({"service.name": "autogen-app"})
)

# Set up OTLP exporter
otlp_exporter = OTLPSpanExporter()

tracer_provider.add_span_processor(BatchSpanProcessor(otlp_exporter))
trace.set_tracer_provider(tracer_provider)

# Instrument OpenAI calls for automatic tracing
OpenAIInstrumentor().instrument(tracer_provider=tracer_provider)

config_list = [{"model": "gpt-4o", "api_key": os.getenv("OPENAI_API_KEY")}]

# Create agents
assistant = autogen.AssistantAgent(
    name="assistant",
    llm_config={"config_list": config_list, "temperature": 0}
)

user_proxy = autogen.UserProxyAgent(
    name="user_proxy",
    human_input_mode="NEVER",
    max_consecutive_auto_reply=3,
    code_execution_config={"work_dir": "coding", "use_docker": False}
)

print("Starting AutoGen conversation (this will be traced)...")

# Start conversation (automatically traced)
user_proxy.initiate_chat(
    assistant,
    message="Write a Python function to calculate fibonacci numbers up to n=10"
)

All AutoGen agent conversations and interactions will be instrumented and exported to Orq.ai through the OTLP exporter. For more details, see Traces.
