This claim is accurate.

Reasoning:

• OpenAI's founding charter explicitly defined its mission as ensuring that artificial general intelligence (AGI) "benefits all of humanity"¹.
• Co-founders Greg Brockman and Ilya Sutskever stated in 2019 that "Our mission is to ensure that artificial general intelligence (AGI)... benefits all of humanity," confirming this was the organization's goal from its early years².
• While the exact wording of OpenAI's mission statement has evolved over time, the core commitment to benefiting humanity has remained consistent since its founding in 2015, initially as "benefit humanity as a whole" and later refined to "benefits all of humanity"³.
