Is there a way to have ChatOpenAI with_fallback function to use circuitbreaker?

[polavishnu4444]

Currently the with_fallback needs to wait for the actual config LLM agent to fail and then only it would go to fallback. In case of any outages, the actual LLM would anyways be failing after a while, is there a way to have some form of circuit breaker that can by pass the first one and directly go to the fallback one instead?

Yes, you can implement a circuit breaker mechanism in the ChatOpenAI.with_fallback function to bypass the primary LLM agent and directly use the fallback in case of outages. By setting max_retries=0, the primary LLM will not retry on errors, allowing the fallback mechanism to take over immediately when an error occurs. This setup ensures that if the primary LLM encounters a RateLimitError, the fallback LLM is used instead ^[1][2].

If the primary is in a state where it is taking very long time then the current way would first hit the primary wait for timeout and then only go to the fallback one. Is there a way we can have the primary tripped and get to use the fallback wholistic?

To address situations where the primary LLM takes too long to respond, you can adjust the request_timeout parameter in the ChatOpenAI class. This parameter allows you to set a timeout for requests, ensuring that if the primary LLM takes too long, the fallback mechanism is triggered more promptly. Additionally, setting max_retries=0 can help prevent retries on errors, allowing the fallback to be used immediately ^[1][2].
