GPTZero’s new Model 3.7b improves drastically on the latest language models from the top providers, just in time for the new 2025/2026 school year.
We’re bringing more transparency to AI detection, with plain-language explanations that show how your text overlaps with AI writing.
Today, we take a major step forward in helping reviewers better identify and understand signs of AI or human writing. Our latest update to the Advanced Scan feature shows what AI-generated text looks like as well as the reasoning behind each detection.
With our latest model update, GPTZero introduces higher granularity in our AI detector by adding a new classification called “AI Polished”. This tag identifies text originally written by a human and later improved by AI.
Back in April, we released a major update (Model 3.1m) that outperformed competitors across the board. Since then, we’ve trained on more challenging human and AI data, and have achieved a less than 1% false positive rate on all supported languages (Model 3.2m).
We’re beyond proud to share that out of hundreds of AI tools, GPTZero has been named as the #1 Best AI Software Product of 2025.
Learn how GPTZero’s new “fact check” for X works and why the leading AI detector is using AI to combat misinformation.
An overview of how AI detectors like GPTZero, TurnitIn, and Copyleaks compare in terms of accuracy rate, error rate, false positives and negatives for identifying AI-generated content.
GPTZero expands its AI detection coverage of LLMs to OpenAI’s latest reasoning models; see our internal benchmarking on how we compare to other AI detectors.
Our latest feature for writers helps you check your claims and back up your arguments with better sourced citations.
