OpenAI's transcription tool called Whisper has come under fire for a significant flaw: its tendency to generate fabricated text, known as hallucinations. Despite the company's claims of "human level robustness and accuracy," experts interviewed by the Associated Press have identified numerous instances where Whisper invents entire sentences or adds non-existent content to transcriptions.

The issue is particularly concerning given Whisper's widespread use across various industries. The tool is employed for translating and transcribing interviews, generating text for consumer technologies, and creating video subtitles.
