Caine Prize: AI detector accuses Zimbabwean author Kundizeza, African writers hit back

On October 6, 2026, Zimbabwean writer Simbarashe Steyn Kundizeza received the Caine Prize for African Writing, which comes with a £10,000 award, for his short story "The Blue Fighter." Less than a week later, the American magazine The Atlantic suggested that the text may have been written using artificial intelligence. CNN reported on the matter on October 21, 2026.

An accusation based on software

The article by journalist Vauhini Vara relies on Pangram, a detector that classifies almost the entire short story as AI-generated, citing stylistic traits such as repetitive phrasing, an abundance of metaphors, and aphorisms. She adds her own interpretation of stereotypes regarding African life, while noting that she could be mistaken, reports the literary site Brittle Paper.

Kundizeza responded on X. "I did not use generative AI to write it," he stated, adding that the text is entirely his own work. He detailed a dated timeline: the first draft was sent on May 15, 2025, to poet Vangile Gantsho, whose poem read during his residency in Ghana had inspired the story; submission to The Shallow Tales Review on May 27; acceptance on June 10; and publication on June 30, 2025. It was the publisher, not him, who submitted the story to the Caine Prize months later.

The reliability of these detectors

The figures gathered by CNN invite caution. Pangram claims a false positive rate of approximately 1 in 10,000. However, a 2025 study from the University of Maryland found that the tool incorrectly labeled 2% of documents as AI-produced. Furthermore, a Stanford study published in 2023 established that detectors were more likely to err on texts written by non-native English speakers—Pangram, created later, was not included in that study, though it claims to measure its own false positive rate at about 8 in 10,000 for that demographic.

The response from the African literary world

Several authors have denounced the approach, reports Brittle Paper. Wale Lawal, founder of The Republic magazine, deemed the article "senseless, racist, and completely unethical." Writer and editor Oghenechovwe Donald Ekpeki recalled that "these attacks against African and Black writers are not new." Novelist Sue Nyathi asked whether an author does not have the right to evolve their style. Tope Folarin, winner of the prize in 2013, called it a "tragedy."

The Caine Prize has not revoked any awards. Its board chair, Ellah Wakatama, indicated that the prize would re-read the story, interview the jurors, and speak with the author, who is expected to provide his draft history. She refuses to consider a detector as evidence: according to her, proof must come from somewhere other than a machine.

There is a precedent: the Commonwealth Foundation cleared regional winners of its short story prize who had been flagged by these same tools, concluding that a detector is not enough to establish certainty. The Caine Prize says it will publish its findings.
