Do you recommend streamUI or the streamobject, streamtext, etc

[Godrules500]

Is it recommended to use streamUI or the streamobject, streamtext, etc? I see there are a lot more changes being applied to streamObject and streamText so I was curious if there was a recommendation of which to use.

It depends on what you're trying to do.

1. Are you generating a structured JSON output with your prompt? -> streamObject
2. Are you generating a text output with your prompt? -> streamText

StreamUI is a bit different, as it allows you to stream back full UI components, but depending on your use case you can handle this yourself too after streaming back the "object". There's a lot of good examples in the documentation. 👍

I am also facing an issue related to stream object and streamUI. Can u pls have a look at my open discussion here https://github.com/vercel/ai/discussions/2153

When you use RSC (React Server Actions), then you'd go for streamUI. If you use client-side hooks, you'd use streamText + useChat or streamObject + useObject.

Being that I am able to use RSC or client-side hooks. Do you know if one has more features than the other? I see a lot of frequent updates for useChat, but I don't see nearly as many updates for RSC changes.

For example, in the latest changes, or experimental changes, I see where useChat has things for file attachments, but I do not see the same for RSC.

We have added a guide for deciding between AI SDK RSC and AI SDK UI: https://sdk.vercel.ai/docs/getting-started/navigating-the-library

Thanks! That actually addressed one of my main struggles that's been plaguing me for weeks.

Re-mounting Issue During Streaming: when using createStreamableUI, components re-mount on .done(), causing undesirable behavior.

We're looking to expand our beta group and soon after into prod. Do you have a timeline of when RSC will be considered "out of dev phase".

As it stands, it unfortunately seems like it may be worth moving to useChat until RSC is stable.

We updated the guide. It is "out of the dev phase" but there are a few issues (like cancelation) that require fixes outside of the AI SDK, and we don't have a timeline for that.
