Support streamText's maxSteps for generateObject and streamObject

[ducan-ne]

Feature Description

Is it possible to support maxSteps for generateObject?

Use Cases

Same as streamText, but I want json return as the result

Additional context

No response

We have added a experimental_output feature to generateText that allows you to create structured information while calling (openai) tools.

Hi @lgrammel , I'm curious if this is working with streamText as well?

[lgrammel]

Not at this point. I'll re-open for streamText

[ducan-ne]

Good to know, in my use case generateText is enough, but streamText looks good too

By the way, I think it would be better if we had an 'onObject' or something similar that calls that method when there's an object extracted in the conversation (though I think it's likely a new feature since generating objects in steps doesn't seem technically possible with just the core), eg extracted objects from tool's output

Does it mean that the plan is not to support tools in streamObject, but instead we'll have to use streamText + experiment_output + tools?

On our side, we have the need to combine streaming + tools + JSON structured output. Right now, it looks like there is no solution for it with the ai SDK, and the only way to do this is to use the OpenAI library.
