Our Take

Minimal and opinionated — OpenAI's Agents SDK does less than LangGraph or CrewAI but does it with far less boilerplate. The handoff primitive for routing between specialized agents is elegant. Now supports 100+ LLMs via any OpenAI-compatible API and LiteLLM. Sessions provide persistent state, and MCP integration is first-class. A strong default choice for teams that want simplicity.

Pros

  • + Extremely simple API
  • + Built-in tracing and debugging
  • + Elegant agent handoff pattern
  • + Lightweight, minimal dependencies

Cons

  • - Limited orchestration patterns compared to LangGraph
  • - Still pre-1.0, API may evolve
  • - Non-OpenAI model support is maturing
