How would you design an AI system for interoperability across different platforms?

To design an AI system for interoperability across different platforms, I would use standardized APIs and data formats like JSON or XML to ensure seamless communication. Implementing microservices architecture would allow each component to operate independently while communicating over defined interfaces. I would also consider adopting existing protocols like REST or gRPC for flexibility. Additionally, incorporating containerization technologies, such as Docker, would enable consistent environments across various platforms, facilitating deployment and scaling. Lastly, I would conduct thorough integration testing to ensure compatibility with target systems.
