- When you want to ensure interoperability between different AI agents irrespective of the frameworks used by them.
When NOT to use agent-protocol
- If you are developing an isolated system with no intention to communicate or integrate with other AI agents outside this scope.
- When working in environments where specific, proprietary interfaces provide significantly better performance or features than adhering to a generic protocol could offer.
Choose leon if…
- leon is primarily TypeScript; agent-protocol is Python.
- Tags unique to leon: speech recognition, text-to-speech.
- Use Leon if you need a personal assistant that operates offline, ensuring your data isn't sent to external servers without review.
When NOT to use leon
