OpenAI Agents SDK

OpenAI Agents SDK

The OpenAI Agents SDK (formerly Swarm) is a production-ready, MIT-licensed Python framework for building agentic applications. It ships with primitives for tool calling, agent handoffs, input/output guardrails, and a powerful tracing UI — plus first-class support for any model via the OpenAI-compatible API.

Key Features

• Agents: define agents as a model + system prompt + list of tools + optional handoff targets
• Handoffs: cleanly transfer control (and context) between specialised agents in a pipeline
• Tool calling: any Python function decorated with @function_tool becomes a callable tool
• Guardrails: input and output validators run in parallel to the agent for fast rejection
• Tracing: built-in OpenAI dashboard traces every step — LLM call, tool call, handoff
• MCP support: mount any MCP server as a tool source without extra glue code

Quick Start

pip install openai-agents

from agents import Agent, Runner, function_tool

@function_tool
def get_weather(city: str) -> str:
    return f"Sunny and 22°C in {city}"

agent = Agent(
    name="Weather Bot",
    instructions="Answer questions about weather using the provided tool.",
    tools=[get_weather],
)

result = Runner.run_sync(agent, "What's the weather in Berlin?")
print(result.final_output)
