Is there a way to change the chat model via API on my chatflow?

[likamee]

The problem is: sometimes Claude goes down for some reason, and even retrying for a short period of time, I cant get an answer from the LLM. My goal is to change the chat model inside my chatflow to preserve the memory, rags and tools via API. Is that possible?

I saw that I could do it via PUT method on the chatflow API, but I don't want to change the entire flowData, just replace a chat model with another
