Zimbabwean author denies using AI to write award-winning story

Zimbabwean writer Simbarashe Kundizeza has denied using artificial intelligence to write his Caine Prize-winning short story, after a report in The Atlantic claimed that AI-detection software had shown the text to be entirely machine-generated.

Kundizeza’s denial came just over a week after he received the £10,000 ($13,000) Caine Prize for African Writing for “The Blue Fighter,” a story about a boy whose family falls on hard times. In a post on X, formerly Twitter, he wrote: “For the avoidance of doubt, I wrote The Blue Fighter.” He did not elaborate.

The dispute began after The Atlantic published an article saying that Pangram, an AI-detection tool, found the story to be “entirely AI generated.” The magazine’s report quickly triggered an uproar among writers and readers on social media, with many questioning whether automated tools can reliably identify AI-created work.

Ellah Wakatama, chair of the Caine Prize, told the BBC’s Front Row programme that she was shocked by the US magazine’s decision to go public with the accusation before a full investigation had been completed. “I do wish The Atlantic had spent more time investigating this so that alongside Pangram, they did have evidence of real human investigation of it before tainting the prize and tainting this winner,” she said.

The Caine Prize is among the most respected literary awards for African short fiction, often serving as a launchpad for writers across the continent. Since its founding in 2000, it has helped bring international attention to African voices. Kundizeza’s win had been seen as a milestone for Zimbabwe’s literary community, which has produced internationally recognised authors in recent years.

The controversy also highlights a growing anxiety within the publishing world about the role of AI in creative writing. Publishers and prize organisers have been forced to adopt new policies on AI-assisted work, and tools designed to detect machine-written text have proliferated. However, experts have warned that automated detection remains unreliable. AI detectors can produce false positives, particularly for writing that is unusually clear, patterned, or distinctive in style.

Wakatama’s comments reflect wider concern that unverified AI allegations could unfairly damage emerging writers. She suggested that The Atlantic should have combined its software results with deeper human analysis before publishing. The story at the centre of the debate, “The Blue Fighter,” follows a boy whose family falls on hard times — a theme that many readers and critics have described as deeply human.

Neither Kundizeza nor The Atlantic has made any further public statements since the exchange. But the dispute has already reopened a broader conversation about how literary institutions should handle AI claims, and how much weight should be given to automated tools in decisions that can shape a writer’s career.

For Zimbabwean writers, the episode is particularly significant. The country has a vibrant literary culture, but its authors often struggle for visibility on the global stage. The Caine Prize has helped change that in recent decades, and the controversy now threatens to overshadow what should have been a celebratory moment.

As the debate continues, the literary world is watching closely. The outcome could influence not only Kundizeza’s career, but also the way future AI-related disputes are handled across the industry.
