Musk Admits xAI Used OpenAI Models for Training Distillation
Why It Matters
This admission could undermine Musk's legal standing against OpenAI and highlights the industry-wide practice of using competitor outputs to train rival models.
Key Points
- Elon Musk confirmed under oath that xAI used OpenAI's models to facilitate the training of Grok.
- The process used is known as 'distillation,' which involves using the outputs of a larger model to train a smaller or newer one.
- Musk defended the practice by claiming that it is a standard behavior among all major artificial intelligence firms.
- The admission may expose xAI to legal liability for violating OpenAI's terms of service, which typically prohibit using outputs to build competing models.
Elon Musk admitted during a legal proceeding on April 30, 2026, that his AI startup, xAI, has utilized OpenAI’s technology to train its own models. Under questioning, Musk confirmed that xAI engaged in "distillation," a technical process where one AI model is used to generate training data for another. When asked specifically about xAI's use of OpenAI’s proprietary technology, Musk stated that "generally all the AI companies" utilize this method and conceded that xAI had done so "partly." This revelation occurs within the broader context of Musk’s ongoing lawsuit against OpenAI. The testimony is significant as it provides factual support for allegations that AI companies frequently bypass terms of service to accelerate development by leveraging the work of their competitors. OpenAI has not yet issued a formal response to the testimony, which may lead to potential counterclaims regarding intellectual property violations.
Elon Musk just admitted that his company xAI used OpenAI’s technology to help build its own AI, Grok. During a legal session, Musk was asked about 'distillation,' which is like using a smarter student's homework to teach yourself the material. Musk didn't try to hide it, saying that pretty much every AI company does this and that xAI is no exception. This is a massive twist because Musk is currently suing OpenAI, and this admission makes it look like he is using their secret recipe while trying to shut them down. It is a classic case of 'do as I say, not as I do' in the tech world.

Forecast
OpenAI is likely to pursue counterclaims against Musk and xAI for breach of service terms following this admission. This could lead to a precedent-setting ruling on whether model distillation constitutes fair use or intellectual property theft.
