Intelligent Failover Realization Solution
Bifrost's disaster recovery system ensures service continuity through a three-tier protection mechanism:
- Request-level real-time health checking, error response reaches the threshold immediately triggers switchover
- Supports configuration of master/standby model chains (e.g. GPT-4 → Claude3 → Gemini)
- Automatic retry mechanism with programmable maximum number of attempts and back-off time
Configuration method:
- Go to the Fallback tab on the Model Configuration page in the Admin interface
- Setting up the primary model (e.g. openai/gpt-4o-mini) and alternative priority lists
- Define trigger conditions (e.g. 3 consecutive timeouts or 5xx errors)
Effectiveness verification: when OpenAI API fluctuates, the system can complete the switch within 200ms, and the request success rate can be maintained above 99.9%. Historical data can be analyzed retrospectively by Prometheus metrics.
