GPT-5.6 drew about 15 million new desktop-app users within two months, and OpenAI filed confidential IPO paperwork. Since the year began, more than a dozen senior executives—including the COO, CRO, CMO, and head of data centers—have departed, citing health concerns and a restructuring that demoted several leaders. CEO Sam Altman is cutting “side projects” to prioritize revenue, while infrastructure now reports to VP Sachin Katti under co-founder Greg Brockman, who is consolidating control ahead of a planned 2027 public offering.
