Caine Prize winner Simbarashe Kundizeza denies using AI to write story

Zimbabwean author Simbarashe Kundizeza has rejected claims that he relied on artificial intelligence to write The Blue Fighter, the short story named winner of the Caine prize for African writers on 6 October 2026. The accusation surfaced in an article by author and journalist Vauhini Vara, published in The Atlantic on 11 October 2026.

Vara wrote that she had fed the story into Pangram, an AI-detection tool that is itself built on AI, and that it classified almost the entire text as machine-generated. The only exception, she said, was an epigraph attributed to an unpublished poem by South African writer Vangile Gantsho. She also argued the prose showed hallmarks she associates with AI writing, including 'not x, but y' constructions, heavy use of metaphor and clichéd aphorisms.

In a statement posted on X, Kundizeza insisted the work was his alone. "I did not use generative AI to write it," he said. He also pushed back on Vara's comparison with a 2021 story of his that she described as different in tone and style, arguing that writers can work across genres and improve markedly over five or more years.

Prize chair questions detection tools

The Caine prize said it was reviewing the allegations and would follow a human-centred process that supports the writer. Its chair, Ellah Wakatama, told the BBC's Front Row programme that she was not opposed to AI but objected to detection software acting as the final judge. She accused The Atlantic of branding the winner a cheat without proper investigation and said she did not want writers, particularly black writers, used as a testing ground for technology she called still rough.

Vara cited Pangram's own research indicating that false positives are rare, including for non-native English speakers, as well as a peer-reviewed paper that found the tool highly accurate on mock academic texts. She conceded to the BBC, however, that independent research on the accuracy of such detectors remains relatively scarce.

A pattern of suspicion

The dispute follows several similar controversies. In July, Trinidadian writer Jamir Nazir won the Commonwealth Foundation's short story prize for The Serpent in the Grove, even as social media critics claimed it bore signs of AI authorship. In September, Canadian-Haitian author Thélyson Orélien's novel C'était Ça Ou Mourir was dropped from the longlist of France's Goncourt prize after an anonymous online account alleged it was largely AI-written.

The case sharpens a growing debate over how far literary institutions should trust automated detectors, and the reputational cost to authors when such tools are used to make public accusations. The Caine prize has not yet announced the outcome of its review.
