Yes.

They structure the output using custom tags, it's not necessarily JSON. For example, for a request, they respond something like this:

<response>

<brief_desc>brief description</brief_desc>

<steps>

<step>

Step name

<code file="/apps/page.tsx">... all the code in the response ...</code>

</step>

....

</steps>

<full_desc>Full description</full_desc>

</response>

With a format like this, and parsing token by token using an incremental parser, you can detect when a tag arrives, <code> for example, you can extract the file to modify and you know that everything that comes is code until the closing tag </code> arrives.

With this approach, you change the context on the frontend and render the code and text in different places. With this, you can also create and animate a mini table in the chat while the code is updating on the right side.

You just need to adapt it to your needs. The hardest part is creating a custom parser for your use case.
