Pros

    • +Lightweight and highly controllable design that avoids steep learning curves while enabling complex multi-agent interactions
    • +Highly customizable architecture allowing developers to build scalable, real-world solutions with flexible agent coordination patterns
    • +Easily testable framework with simple primitives that make debugging and validation straightforward

    Cons

      • -Experimental and educational status means it's not intended for production use cases
      • -Now officially replaced by OpenAI Agents SDK, making it a deprecated solution
      • -Stateless design between calls requires external state management for persistent conversations

      Use Cases

        • •Learning and experimenting with multi-agent orchestration patterns in a controlled educational environment
        • •Prototyping systems with large numbers of independent capabilities that are difficult to encode in single prompts
        • •Building lightweight agent coordination systems where full state management isn't required
