GPTinf vs WriteHuman
On the October 2026 leaderboard, GPTinf leads WriteHuman 80.74 to 75.06, a gap of 5.68 points. GPTinf ranks #3 and WriteHuman ranks #7 out of 11 tools. GPTinf scores higher on none of the 7 detectors and in 6 of 7 writing categories. WriteHuman is ahead on bypass rate (97.6% vs 88.7%), consistency (96.0 vs 92.1) and GPTZero (100.0 vs 55.1). The two tools' 95% confidence intervals for bypass rate overlap, so that difference is not statistically clear.

Score components
The overall score weights bypass rate at 42%, meaning preservation at 32%, readability at 16% and consistency across writing categories at 10%. Penalties for output-quality failures are then subtracted. Full scoring formula
Overlapping CIs means the two tools' 95% confidence intervals for bypass rate overlap, so the bypass difference is not statistically clear.
Detector by detector
Each figure is one detector's average human-likelihood score across all of a tool's outputs, on a 0–100 scale. Higher means more human. WriteHuman scores higher on all 7 detectors.
Writing categories
Each category score applies the overall-score weights to that category's prompts only. Bypass, meaning preservation and readability are averaged within the category, and the tool's overall consistency score is added. Penalties are not subtracted. Categories with few prompts give less reliable scores, so each row shows its prompt count.
Where each one wins
Measures where one tool is ahead of the other. Ties are left out. Score components come first, then detectors, then categories, with the largest gap first in each group.
