Description

When there is an ongoing AI streaming, switching the chat ID and causing a re-render of useChat can lead to some abnormal situations.

The data from the ongoing AI stream will overwrite the data of the newly switched chat ID.

Code example

<ParentComponent /> (useChat)
      <FirstChild  messages={messages} />
     <Button>Swtich Chat ID</Button>
<SecondChild /> 

Additional context

All client components, and all the data have been fully loaded on client.

I am also running into this, it seems like a big limitation. I want to support multiple parallel chats, potentially using different providers.

Also running into this issue, any news how to resolve, or if known issue, any ETA?

with ai sdk 5, you now manage chats in separate chat objects
