Elon Musk has expanded his lawsuit against the ChatGPT maker OpenAI, adding federal antitrust and other claims and adding OpenAI's largest financial backer, Microsoft, as a defendant. Musk's amended lawsuit, filed on Thursday night in federal court in Oakland, California, said Microsoft and OpenAI illegally sought to monopolize the market for generative artificial intelligence and sideline competitors. Like Musk's original August complaint, it accused OpenAI and its chief executive, Samuel Altman, of violating contract provisions by putting profits ahead of the public good in the push to advance AI. "Never before has a corporation gone from tax-exempt charity to a 157bn for-profit, market-paralyzing gorgon – and in just eight years," the complaint said. It seeks to void OpenAI's license with Microsoft and force them to divest "ill-gotten" gains. OpenAI in a statement said the latest lawsuit "is even more baseless and overreaching than the previous ones".

Elon Musk has withdrawn his lawsuit against OpenAI, a day before a judge was set to hear a request for dismissal. Musk sued OpenAI, saying its founders had violated its nonprofit status, to become a de-facto part of Microsoft. OpenAI said there was no such violation, and the lawsuit was likely a way for Musk to gain access to its secrets. Despite ending the suit, Musk might be nursing this grudge, tweeting if Apple integrates OpenAI's tools into its software, he'll ban iPhones from his companies.

If you'll recall, The Times sued both companies for using its published articles to train their GPT large language models (LLMs) without permission and compensation. In its filing, the company has accused The Times of pushing "doomsday futurology" by claiming that AI technologies pose a threat to independent journalism. It follows OpenAI's court filing from late February that's also seeking to dismiss some important elements on the case. Like OpenAI before it, Microsoft accused The Times of crafting "unrealistic prompts" in an effort to "coax the GPT-based tools" to spit out responses matching its content. It also compared the media organization's lawsuit to Hollywood studios' efforts to " stop a groundbreaking new technology:" The VCR. Instead of destroying Hollywood, Microsoft explained, the VCR helped the entertainment industry flourish by opening up revenue streams.

Elon Musk started the week by posting testily on X about his struggles to set up a new laptop running Windows. He ended it by filing a lawsuit accusing OpenAI of recklessly developing human-level AI and handing it over to Microsoft. Musk's lawsuit is filed against OpenAI and two of its executives, CEO Sam Altman and president Greg Brockman, both of whom worked with the rocket and car entrepreneur to found the company in 2015. A large part of the case pivots around a bold and questionable technical claim: That OpenAI has developed so-called artificial general intelligence, or AGI, a term generally used to refer to machines that can comprehensively match or outsmart humans. The case claims that Altman and Brockman have breached the original "Founding Agreement" for OpenAI worked out with Musk, which it says pledged the company to develop AGI openly and "for the benefit of humanity. Musk's suit alleges that the for-profit arm of the company, established in 2019 after he parted ways with OpenAI, has instead created AGI without proper transparency and licensed it to Microsoft, which has invested billions into the company. It demands that OpenAI be forced to release its technology openly and that it be barred from using it to financially benefit Microsoft, Altman, or Brockman. "On information and belief, GPT-4 is an AGI algorithm," the lawsuit states, referring to the large language model that sits behind OpenAI's ChatGPT. It cites studies that found the system can get a passing grade on the Uniform Bar Exam and other standard tests as proof that it has surpassed some fundamental human abilities. "GPT-4 is not just capable of reasoning.
