OpenAI SDKs: AgentKit Agent Builder (vs n8n)

OpenAI provides various SDKs for AI SW devs:

- standard AI API for request/response and chat, including support for "function calling/tools"
- Agents SDK with more advanced "AI Agents"
- AgentKit SDK integrated visual toolset for building Agents.

  • Enough features to be worth using, but few enough primitives to make it quick to learn.
  • Works great out of the box, but you can customize exactly what happens.
main features of the SDK:
  • Agent loop: Built-in agent loop that handles calling tools, sending results to the LLM, and looping until the LLM is done.
  • Handoffs: A powerful feature to coordinate and delegate between multiple agents.
  • Guardrails: Run input validations and checks in parallel to your agents, breaking early if the checks fail.

  • Sessions: Automatic conversation history management across agent runs, eliminating manual state handling.
  • Function tools: Turn any Python function into a tool, with automatic schema generation and Pydantic-powered validation.
  • Tracing: Built-in tracing that lets you visualize, debug and monitor your workflows, as well as use the OpenAI suite of evaluation, fine-tuning and distillation tools.
