Swarmopen-source

Educational framework exploring ergonomic, lightweight multi-agent orchestration. Managed by OpenAI Solution team.

+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

-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

•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
