The Early Founding and Funding of OpenAITesla’s Self-Driving SystemxAI and the Grok Model

Who they are

Elon Musk (1971– ) is an American entrepreneur who in 2015 co-founded OpenAI with Sam Altman and others and provided its early main funding, one of the original founding intents being to counterbalance Google, then seen as dominant in AI. In 2018 Musk left the board over a disagreement with OpenAI management on development path and control, and the two sides’ relationship thereafter turned from cooperation to open business and legal dispute, Musk publicly criticizing OpenAI many times for departing from its original non-profit mission and turning to over-commercialization. Musk’s company Tesla long invested in self-driving research, its "Full Self-Driving" (FSD) using a pure-vision scheme abandoning the LiDAR sensors peers commonly use, a technical-path choice long controversial in the industry. In 2023 Musk struck out on his own to found xAI, releasing the Grok series of large language models with a product positioning of "less content moderation, more rebellious spirit," and in 2025 xAI merged with Musk’s social-media platform X.

Key stories

From Co-Founding to Open Rupture

Musk was one of OpenAI’s earliest and most important funders, one of the original cooperative intents being to prevent the power over AI development being over-concentrated in Google alone. But in 2018 he left the board over a disagreement with the other founders on the company’s path and his own demand for control, and the two sides’ relationship gradually worsened, Musk accusing OpenAI publicly many times of betraying its original "non-profit, benefit all humanity" founding mission and turning to maximize commercial profit, the two even entering formal litigation over it, this story of "the founders falling out" thereafter an important case for examining the internal divergence of ideas in the AI industry.

Version differences

Musk and OpenAI thereafter had a legal dispute over whether the company’s development path had strayed from its original non-profit purpose, the two sides’ accounts and demands markedly at odds, and this site states the publicly known course of the facts without judging the rights and wrongs of the litigation.
