Musk v. Altman: when asked whether xAI has distilled OpenAI models, Elon Musk says the claim is “partly” true
Wired
Context & Ripple Effects
The related coverage places the remark inside an escalating Musk–OpenAI dispute: Musk has publicly attacked Altman and Brockman ahead of a trial, while the latest exchange turns from those broader accusations to xAI’s own development practices.
That shift matters because a partial acknowledgment creates a more concrete point of scrutiny than the surrounding personal and governance claims, directly linking the dispute to how competing models are built.
First-order effects
Musk’s statement weakens any categorical public denial that xAI used OpenAI-derived model outputs, putting xAI’s development practices under sharper scrutiny.
The admission becomes a salient factual issue in the wider Musk–OpenAI conflict, alongside Musk’s existing allegations against OpenAI’s leadership.
Second-order effects
Rival model developers have added reason to tighten controls, monitoring, and contractual boundaries around model access where outputs could be used to train competing systems.
The dispute raises the commercial importance of being able to document how a model was trained, rather than relying solely on performance claims or public positioning.
Third-order effects
If similar disputes persist, model provenance and permissible use of model outputs could become a more central competitive and legal boundary among frontier-AI labs.
The longer-term effect is likely to be more formalized separation between model providers and downstream developers, though this case alone does not establish how that boundary will be enforced.
The trend: Frontier-AI competition is increasingly turning model access and training provenance into strategic points of conflict, not just technical implementation details.
i am getting a lot of questions about this so i just want to make clear that it was a brief exchange and OAI's lawyer did not seem to want to pursue it further after musk affirmed the practice. (musk also noted that it was a common practice among the labs)

Musk doubled down that everyone is doing this. He also said it's standard practice for AI labs to use other AI models to validate their own, which seemed more known. https://www.wired.com/...
Elon's lawsuit against OpenAI is really not about Grok. But a line of questioning this morning veered into how xAI trains its AI models, potentially using their competitor's technology: Lawyer: Do you know what distillation is? Musk: It means to use one AI model to train another …
What people call “distillation” is a super common practice (you use other models to benchmark your model, to evaluate your inputs or to add a little bit to your datasets) that in my opinion should be covered by fair use (just like using public data is), especially when the result…
I think OpenAI did basically betray its commitments to its early investors but it's so absurd to have Musk being the one suing when he 1) didn't seem to care until it affected him personally and 2) is now running a fully for-profit competitor.
it is quite significant that Musk admitted on the stand that xAI is distilling OpenAI models to train xAI, and that it is using OpenAI's technology to build xAI!
LIVE TRIAL UPDATE: OpenAI's counsel asked Musk whether xAI has ever “distilled” technology from OpenAI. Musk: “Generally AI companies distill other AI companies.” “Is that a yes?” Savitt asked. Musk: “Partly.”
