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
