Elon Musk said that Tesla owners will “soon” have access to Grok, a large language developed by Musk’s xAI startup, days after the AI started calling itself ‘MechaHitler’.
Yesterday, xAI launched Grok 4, the latest version of its large language model.
The new model is benchmarking very well, but that’s generally the case with the latest model to come out. It edges the latest models from Google and OpenAI on intelligence by a few points, but it falls behind on speed:

At the launch event, Musk announced that Grok will “soon” be integrated into Tesla vehicles.
This is something that the CEO has been discussing since founding xAI, which has been controversial because Musk has also positioned Tesla to compete in the AI space. He even stepped down from his role at OpenAI due to a “conflict of interest with Tesla.”
The announcement of the imminent integration of Grok into Tesla vehicles comes just days after the language model went haywire on X and started praising Hitler, referring to itself as ‘MechaHitler’, and made several antisemitic comments.



xAI acknowledge the issue and put Grok on timeout while they fixed it:
We are aware of recent posts made by Grok and are actively working to remove the inappropriate posts. Since being made aware of the content, xAI has taken action to ban hate speech before Grok posts on X. xAI is training only truth-seeking and thanks to the millions of users on X, we are able to quickly identify and update the model where training could be improved.
The “bug” came just a few weeks after Musk stated that he was displeased with Grok supporting left-wing narratives, even though it didn’t say anything inncurate, and that he would update Grok to “fix” it.
Now, the large language model (LLM) is expected to power the new voice assistant inside Tesla vehicles.
LLMs are becoming quite common in cars, especially premium vehicles. Ford, Mercedes-Benz, Stellantis, and a few others have all integrated Chat-GPT in some models.
Many Chinese automakers have also developed their own and deployed them in cars, even entry-level ones.
Tesla is playing catch up on that front.
Electrek’s Take
As I have previously stated, I think Musk is setting up Tesla to invest or even merge with xAI at a ridiculous valuation – making Tesla shareholders virtually pay twice for Twitter, which is now part of xAI.
This is how he will be able to gain wider control over the company’s share.
Of course, it will be widely challenged in court. In fact, shareholders have already filed a lawsuit alleging that Musk was in breach of fiduciary duties to Tesla shareholders when he started xAI.
