Recursive function calling with ai/rsc

[olegkorol]

Hi!

I used to achieve recursive function calls like this:

const stream = OpenAIStream(initialResponse, {
  async experimental_onFunctionCall({name, arguments: args}, createFunctionCallMessages) {
    console.log('function call needed:', name, args)

    const functionResult = await runFunction(name, args);
    console.log('function result:', functionResult)

    const newMessages = createFunctionCallMessages(functionResult);

    return openai.chat.completions.create({
      model: GPT_MODEL,
      stream: true,
      messages: [...messages, ...newMessages],
      functions,
      function_call: 'auto'
    })
  },
  
  // ...

})

Now I am testing the new ai/rsc with generative UI and wonder if/how I can achieve the same behaviour.

Thanks!
