Who died:

• Suchir Balaji, a former OpenAI researcher and whistleblower, passed away on November 26, 2024. While local authorities and the medical examiner ruled his death a suicide, his parents have publicly disputed the finding. Because he was a key figure who had recently left the company to speak out about copyright concerns, his passing has drawn continued public attention and media scrutiny. ^{1) 2) 3)}
