OpenAI Agents SDK is an open-source Python framework for building agentic apps with handoffs, guardrails, sessions, tracing, MCP tools, sandbox agents, and realtime voice agents.
OpenAI Agents SDK is a Python framework for building production-style AI agents on top of OpenAI models and, through adapters, other LLM providers. The most important thing to understand is that it is not another hosted no-code agent builder. It is a developer SDK: you install it with `pip install openai-agents`, write Python, define agents with instructions and tools, and let the runtime manage the agent loop, tool calls, handoffs, guardrails, sessions, and tracing.
The official docs describe a small set of primitives: agents, agents-as-tools or handoffs, and guardrails. That restraint is useful. Instead of forcing teams into a visual workflow model, the SDK lets Python developers compose normal code with agent behavior. A support workflow, for example, can use one triage agent, hand off billing issues to a specialist agent, call internal functions, and run input/output guardrails before anything reaches a customer. A research or coding workflow can use sandbox agents to work inside a real filesystem, inspect files, run commands, apply patches, and resume work across longer tasks.
