Caine Prize reviews its winning story after AI-detection claims
The Pangram detector flagged the story as AI-written while rating all 25 earlier Caine Prize winners human; the author denied using generative AI and provided draft history.

Five days after Zimbabwean writer Simbarashe Steyn Kundizeza won the £10,000 Caine Prize for African Writing for his short story “The Blue Fighter,” journalist Vauhini Vara reported in The Atlantic that the Pangram AI-detection tool had flagged nearly the entire text as machine-generated. The Caine Prize said it was opening a review, and Kundizeza denied using generative AI.
According to accounts of Vara’s piece, Pangram’s stylometric classifier rated almost the whole of “The Blue Fighter” as falling within the statistical profile of AI-generated writing, while rating all 25 previous Caine Prize-winning stories, and Kundizeza’s own 2021 story “The Whistleblower,” as fully human-written. Kundizeza rejected the allegation directly: “I wrote ‘The Blue Fighter.’ I did not use generative AI to write it. It is entirely my own work.” He set out a documented chronology of the story’s development, including an early draft sent to a fellow writer in May 2025 and its acceptance by The Shallow Tales Review the following month.
The response from African writers and critics was largely hostile to the Atlantic’s framing: The Republic’s founder Wale Lawal called the piece “crazy, racist and wildly unethical,” and journalist Karen Attiah said Black, Caribbean and African writers had repeatedly become “the global face of AI use and plagiarism” allegations. Critics also questioned the detector’s reliability — Pangram’s own cited figures suggest roughly one false positive per 24,000 cases, but independent validation of its accuracy across nationalities and English dialects was described as limited.
Caine Prize chair Ellah Wakatama said the £10,000 prize had not been withdrawn while the prize interviewed judges and the story’s original publisher, adding: “I do wish The Atlantic had spent more time investigating this so that alongside Pangram, they did have evidence of real human investigation before tainting the prize and tainting this winner.” A similar AI-authorship allegation against a Commonwealth Short Story Prize entrant earlier in 2026 was not upheld.
