The generative answer is a text that is generated chunk by chunk by the language model. It is retrieved through a readable HTTP stream, so the chat() method returns an Observable emitting a value each time a new chunk is available. The incomplete attribute of the emitted value indicates if the asnwer is complete or not.

Example:

 nuclia.knowledgeBox
   .ask('where does the Little Prince live')
   .pipe(filter((answer) => !answer.incomplete))
   .subscribe((answer) => {
     console.log(answer.text);
   });
