In 2015, he was the owner of the “X” platform and one of the richest men in the world thanks to his companies “Tesla” and “SpaceX” among the founders of “Open AI”, along with Sam Altman, the current general manager.

But Musk resigned from the company in 2018, and has now become one of its most prominent critics.

Last year, he founded his company specializing in artificial intelligence, XAI.

In documents submitted to a San Francisco court and seen by Agence France-Presse on Friday, the billionaire OpenAI and its director, Sam Altman, were accused of violating the company's founding contract.

OpenAI was founded as a non-profit organization that aims to work for the good of humanity and uses “open source” artificial intelligence programs (available and capable of being modified, used, and redistributed).

But contrary to these goals, the company did not publish the code for the latest version of its program, “GPT4,” in violation of the “founding contract,” according to what Musk’s lawyers asserted in the lawsuit.

They considered that the founding contract had become questionable, accusing “OpenAI” of turning into a profitable company “with potentially catastrophic repercussions for humans.”

Musk's lawyers continued: "OpenAI has become a de facto closed-source subsidiary of the largest technology company in the world, Microsoft."

OpenAI has become one of the most important companies since it launched its generative artificial intelligence program, ChatGPT, in late 2022. In recent years, Microsoft has invested about $13 billion in the startup, which has since redirected itself towards a profitable path.

Musk's lawsuit noted that "the defendants chose, contrary to the articles of association, to use GPT4 not for the benefit of humans, but rather as an exclusive technology intended to maximize profits for the largest company in the world."

Musk specifically asked for GPT4 to be removed from the permit granted by OpenAI to Microsoft, in addition to receiving unspecified compensation.

The transformation of OpenAI played a role in the dismissal of its board of directors, Sam Altman, in November, but Altman, with the support of Microsoft, returned to his position in the company days later.

OpenAI is also subject to regulatory oversight.

The European Commission announced last January that it was checking “whether Microsoft’s investment in OpenAI” should be “subject to review.”

Also, at the end of last January, the US Federal Trade Commission (FTC) announced the launch of an investigation into the investments of Microsoft, Google, and Amazon in the two major startups, OpenAI and Anthropic. The field of artificial intelligence.

The Wall Street Journal reported that the US Securities and Exchange Commission is looking into Sam Altman's internal communications, as part of an investigation into the circumstances that led to his dismissal and then his return to the company in November.
