On the record

What was OpenAI created to be — and did it abandon that purpose?

A nonprofit built as a public-interest counterweight became a closed, profit-seeking Microsoft partner — the opposite of what was promised.

Building safe AGI required capital and compute at a scale the nonprofit couldn't raise; the capped-profit structure, still governed by the nonprofit board, serves the same mission.

OpenAI is announced as a nonprofit

Contested · 2 accounts

OpenAI was founded in 2015 as a nonprofit committed to safe AGI 'for the benefit of all humanity,' with an emphasis on openness. In 2019 it created a for-profit 'capped-profit' subsidiary and took major investment from Microsoft. It became far less 'open' about its models over time. Musk left in 2018 and later sued, alleging betrayal of the mission.

Unresolved: Whether the capped-profit structure honors or subverts the founding charter.

Elon Musk's claim

Claim — not established history

That OpenAI betrayed its founding purpose — a nonprofit committed to open, safe AGI for humanity — by becoming a closed, for-profit company effectively controlled by Microsoft.

Claimed by Elon Musk, 2024
Response — OpenAI (Altman, Brockman, Sutskever)

OpenAI countered that Musk himself had wanted a for-profit structure and majority control (or a Tesla merger), that the capped-profit turn was necessary to fund AGI research, and published emails to support that account.
