How to balance speed and quality in body generation

A growing number of tools can generate a substantial amount of body text at once from a specified outline or set of headings. Tools that let you finely specify reference article URLs or tone tend to produce a draft that's easier for the writer to finish editing themselves. On the other hand, factual errors or unnatural phrasing in generated text occur at a certain rate, so the step of a human reading through for fact-checking and adjustment before publishing can't be skipped.

Perspectives for comparing body-generation tools

  • Consistency and naturalness of the body text when given a heading or outline
  • Range of customization available, such as reference articles or tone specification
  • How well it limits factual errors in generated text (hallucination countermeasures)
  • Processing speed and concurrency when generating a large batch of articles in parallel
