Caine Prize clears Simbarashe Kundizeza of AI writing allegations

Zimbabwean author Simbarashe Kundizeza has been cleared of using generative artificial intelligence to write The Blue Fighter, the short story that won the £10,000 Caine Prize for African Writing. Organisers concluded a month-long investigation by confirming that his award stands.

The story was announced as the winner on 6 October. It follows the declining fortunes of a family after the father invests in fish tanks, placing family relationships and financial hardship at the centre of its narrative.

The investigation followed an article in The Atlantic questioning whether the story had been written using AI. The allegation drew on an assessment by the detection tool Pangram, rather than an admission by the author, who consistently denied using generative AI to produce the work.

In its 11 November statement, the prize said reviewers interviewed Kundizeza, the judging panel and The Shallow Tales Review, which first published the story. An independent digital forensic investigator also examined draft metadata, while documentation supplied by the author and publisher traced the work’s development.

Organisers said the evidence included four draft documents representing up to 27 hours of writing and editing. They found no evidence of generative AI production and said detection tools alone could not reliably establish authorship. The board considers the case closed.

Kundizeza told The Associated Press he was relieved by the outcome and wanted to return his attention to writing. He has described the story as personal, saying its characters and setting draw partly on his own family’s experiences during Zimbabwe’s economic difficulties. His account places lived experience behind the fictional family’s struggles.

The accusation also prompted debate about how African writers are judged when their work is flagged by automated tools. Some writers and readers questioned whether Black authors were being unfairly singled out. Those concerns formed part of the public response to the allegation, rather than a finding that any particular detection system had discriminated against Kundizeza.

For literary prizes, the case highlights the distinction between a software assessment and a review of how a manuscript developed. Here, the organisers examined drafts and sought accounts from people involved in writing, publishing and judging the story. Their decision upheld the award rather than treating an automated classification as conclusive.

The prize will introduce AI declarations for submitting publishers and shortlisted writers when its next submissions open on 23 November. It also plans guidance for judges and a published procedure for future concerns. Chair Ellah Wakatama said organisers looked forward to celebrating Kundizeza in Zimbabwe before the end of the year.
