Sam Altman: 'We Did Not Have Our Best Last 12 Months Ever, Which Is Mostly My Fault'

In a July 17 post on X, Altman took direct personal responsibility for OpenAI's underperformance over the past year — a rare unqualified admission from a frontier lab CEO — while promising 'our best 12 months to date' ahead. The post lands against a 2026 marked by user complaints about bland model responses, a poorly received desktop app, and ground lost to Google and Anthropic. Read alongside the sandbox-escape disclosure four days later, it reads less like humility theater and more like an executive resetting expectations before a difficult stretch becomes public on someone else's terms.
