On this page, review any information or notes related to our most-recent releases for Turnitin's AI writing detection model.
We have updated our AI writing detection model to improve recall while maintaining a low false positive rate.
This release does not require any changes to your settings. There are no visual changes to the AI writing report or the highlighting within the report.
This release will not retroactively update previously-generated AI writing reports. To view the AI writing score generated by this update, existing submissions must be resubmitted.

Turnitin is excited to release an update to the AI writing detection capabilities that includes detection of the likely use of AI bypasser tools. These tools attempt to modify AI-generated text to appear more human-like, with the goal of avoiding detection by AI writing indicators.
With this release, the ‘AI-generated only’ category in the AI writing report will now include the percentage of AI-generated text that may have been modified by an AI bypasser tool.
Turnitin is excited to release its AI writing detection capabilities in Japanese to help educators uphold academic integrity for Japanese language submissions.
With this release, our AI writing detector can process submissions written in Japanese for text that was likely AI-generated. Once submitted, a Japanese AI writing report is generated for instructors to review. Previously submitted Japanese assignments can be checked with our AI writing detection when they are re-submitted to Turnitin and if you have AI writing enabled for your account.
Please note our Japanese AI writing model is a different model than our and models. Turnitin’s Japanese AI model has detection capabilities that have been trained with Japanese language writing and to detect text likely generated with the GPT-4 (version 0613), GPT4-o (released 13/05/2024 & 06/08/2024), and GPT-4o-mini (released on 18/07/2024) large language models. As our Japanese and English AI detection capabilities differ, please read more in our Japanese AI Writing FAQ.
Turnitin is excited to release its AI writing detection capabilities in Spanish to help educators uphold academic integrity for Spanish language submissions.
With this release, our AI writing detecto r can process submissions in Spanish for text that was likely AI-generated. Once submitted, a Spanish AI writing report is generated for instructors to review. Previously submitted Spanish assignments can be checked with our AI writing detection when they are re-submitted to Turnitin and if you have AI writing enabled for your account.
Please note our Spanish AI writing model is a different model than our model. Turnitin’s Spanish AI model has detection capabilities that have been trained with Spanish language writing and to detect text likely generated with the GPT-3.5 and GPT-4 large language models. As our Spanish and English AI detection capabilities differ, please read more about how our .
With this release, the AI writing report now displays a submission’s overall percentage of text detected as AI and a breakdown of that score in two interactive categories:
These categories provide more granularity into what AI capabilities were used and where, as well as their frequency within the submission. Selecting a category will bring the first highlight detected in the submission into focus.
The AI writing report now supports submissions with up to 30,000 words of qualifying text.
False positives (incorrectly flagging human-written text as AI-generated) are a possibility in AI models. To avoid potential incidence of false positives, no score or highlights are attributed for AI detection scores in the 1% to 19% range. When AI is detected below the 20% threshold in the report, it is now indicated with an asterisk (*%) and no percentage is attributed. This update goes into effect for all reports generated after this release; reports generated previous to this release will still display scores between 0-19 with an asterisk.
Users will also see an updated AI detection chart in the administrators statistics page. Updates to the chart include new contextual help and a separate data column for AI reports with no percentage attributed (percentages within the 1-19% range), indicated with an asterisk (*%).
We have fixed a prose text, long-form writing format bug that was inadvertently introduced in the December 6th update. This bug allowed submissions that did not meet the file requirements (less than 300 words) to be processed and given an AI writing detection score.
\nThis issue has now been resolved.
\nSome AI reports generated in this period (6th December to 15th December 2023) did not meet the file requirements but generated an AI writing detection score. Results show that our accuracy increases with a little more text so submissions that cont ai n less than 300 words may result in an AI writing score that is likely less accurate. Please be reminded that an AI Writing score should not be used as the sole basis for adverse actions ag ai nst a student.
\nAI word spinners are sometimes used to avoid identification of AI -generated text. We now detect likely AI -generated text even if it may have been paraphrased using an AI word spinner.
\nOur AI paraphrasing detection is incorporated into our AI writing detection capability and does not require any change to your settings. There are no visual changes to the report, or the highlighting in the report, with this update. Previous reports will need to be resubmitted to detect likely AI paraphrasing.
\nWe are now able to process long-form prose text in tables. Resubmit to reprocess existing submissions that cont ai n tables.
\nWe have increased the maximum word count for a sentence to include lengthy sentences when processing the report.
\nWe have fixed a bug that was occasionally highlighting AI writing within references listed in a bibliography. Bibliographies are now excluded when processing the AI writing report. Resubmit to reprocess existing submissions that cont ai n highlighted reference sections.
\nSince launch, we have observed a higher incidence of false positive detection in the first few or last few sentences of a document. Many times these sentences consist of introduction or conclusion content written in a generic way. As a result, we have changed our detection logic to help reduce these false positives.
\nWe also worked on making our segment boundaries detection more precise which could lead in some rare cases to change of boundaries compared with a previous version.
\nWe have fixed a bug that was causing inconsistent text formatting that was impacting the AI writing percentage. This fix ensures that the model provides more consistent and accurate determinations.
