Yes. Portkey's routing engine can automatically select the most cost-effective model for each request type based on quality requirements, response time needs, and budget constraints, with continuous optimization based on usage patterns.
Portkey provides high availability with multiple region deployments. For maximum reliability, the on-premises version eliminates dependency on Portkey's infrastructure while maintaining all routing and optimization features.
