Failover
Automatic switching to a backup system when the main system fails.
Failover is like having a backup generator for your house. If the main power goes out, the generator automatically kicks in so your lights and appliances keep working.
In AI, this means if one AI model or service stops working or becomes too slow, the system automatically switches to another one to keep your application running without interruption.
Failover is the automatic switching to a redundant or standby system upon the failure of a primary system. This ensures continuous operation and availability of services. In the context of AI models, failover mechanisms can route requests to alternative models or providers if the primary choice is unavailable, experiences high latency, or returns an error.
Recent discussions highlight the need for robust AI applications. Designing failover strategies across different model providers is becoming crucial for maintaining service reliability as AI systems grow more complex.

The concept of failover originated in the field of computer systems engineering to ensure continuous operation of critical infrastructure.
You can observe failover indirectly by using an AI assistant that might occasionally switch its underlying model. If you notice a sudden change in response style or speed, it could be a sign of a failover event.

Questions people ask
- Why is failover important for AI?
- Failover is important for AI to ensure that applications remain available and responsive even if the primary AI model or service experiences issues.
- What happens if an AI model fails?
- If a primary AI model fails, a failover system will automatically switch to a backup model or service to prevent service disruption.
