In short
Elon Musk’s xAI has sued OpenAI, alleging it induced former workers to steal supply code and information heart deployment methods.
The AI firm alleges OpenAI focused workers with information of its “secret sauce” information heart operations, with one government refusing to signal confidentiality paperwork after leaving for OpenAI.
One engineer allegedly admitted in a “handwritten confession” to misappropriating code after encrypted communications with an OpenAI recruiter.
Elon Musk’s synthetic intelligence firm xAI filed a federal lawsuit on Wednesday in opposition to OpenAI, accusing its rival of orchestrating a “coordinated, unfair, and illegal marketing campaign” to steal proprietary expertise via focused worker poaching.
The criticism, filed in California, alleges OpenAI “by some means” induced former xAI workers to misappropriate the corporate’s whole supply code, coaching strategies, and information heart deployment methods.
Musk, a co-founder of OpenAI alongside Sam Altman, Greg Brockman, Illya Sutskever, and others in 2015, stepped down from the board in 2018, citing conflicts of curiosity along with his firm, Tesla, and its self-driving vehicles. Since then, the tech billionaire has assumed a combative stance in opposition to OpenAI, together with submitting a separate lawsuit final month.
OpenAI recruiter Tifa Chen concurrently focused a number of xAI workers, providing multi-million greenback packages to engineers who then stole supply code and uploaded it to non-public units inside hours of their communications, the lawsuit alleges.
Xuechen Li, an early xAI engineer, allegedly “uploaded the whole xAI supply code base to a private cloud account” in July 2025, and later “admitted in a handwritten confession” that he misappropriated xAI’s code and presentation supplies on coaching methods.
The lawsuit particulars timestamps displaying Li’s code theft occurred inside hours of encrypted Sign messages with Chen, who allegedly responded “no manner!” after Li copied the recordsdata, earlier than OpenAI prolonged its multi-million greenback supply.
Jimmy Fraiture, one other early xAI engineer, allegedly “used the AirDrop characteristic to switch” confidential supply code “a minimum of 5 instances” after signing with OpenAI, stealing “nearly all of xAI’s code” he oversaw, plus experimental folders from 4 co-founders.
An unnamed senior finance government who left for OpenAI allegedly referred to as these operations xAI’s “secret sauce,” saying, “The information heart crew. Their velocity and precision blew me away. I might NEVER wish to compete in opposition to them.”
The manager then took a lesser function at OpenAI, targeted on information heart spending technique although he had no prior AI expertise, and when confronted about confidentiality obligations, allegedly “responded with crude sexual expletives” and refused to signal termination paperwork.
Navodaya Singh Rajpurohit, authorized associate at Coinque Consulting, advised Decrypt the case “leans closely on worker poaching,” noting that whether or not it crosses from aggressive recruiting to illegal misappropriation “will depend upon proof not included within the submitting,” and that “hiring alone isn’t sufficient to show trade-secret misuse.”
Ishita Sharma, managing associate at Fathom Authorized, advised Decrypt that xAI should outline its “secret sauce” broadly, grouping GPU racking, vendor contracts, pricing curves, and orchestration playbooks, which, she famous, may be described “by the outcomes they ship — like sooner deployment or cheaper scaling, with out placing the precise technical diagrams or formulation on the document.”
Sharma mentioned “the recruiter angle is trickier,” since legal responsibility relies on whether or not recruiters acted as brokers of OpenAI with the corporate’s information.
For OpenAI’s protection, she defined, the strongest method could be to point out unbiased creation via “time-stamped information: inner Git commits, R&D notes, provider invoices, and emails,” with earlier documentation offering essentially the most credibility.
xAI seeks damages, restitution, and injunctions requiring OpenAI to purge xAI materials from its methods and even destroy fashions constructed with it.
The lawsuit provides to Musk’s ongoing authorized battle with OpenAI, as final month, his corporations filed an antitrust go well with in opposition to Apple and OpenAI, claiming their unique iPhone integration creates unfair market dominance.
