Detection performance
GPTinf: Marketed as being trained directly against detector models rather than general paraphrasing, which independent testers cite as the reason its scores hold up on technical text.
BypassGPT: Testers consistently place it in the middle of the pack rather than the top or bottom tier.
AI detector included: Neither tool bundles a built-in detector — pair either with GPTZero or Originality.ai.
