Elon Musk has once again set the autonomous driving debate ablaze by assuring that Tesla vehicles with the Artificial Intelligence chip (also called Hardware 4 or HW4) would be able to reach unsupervised self-driving without any further hardware upgrades. The quote supports the long-term policy of Tesla to futurize autonomy not by regularly replacing hardware with new versions of it, but by improving software and neural networks.
It was confirmed in response to a post on the social media platform X, in which a Tesla fan wrote that the current AI4 hardware was already strong enough to support unsupervised Full Self-Driving (FSD). Musk responded with “Yup,” which was similar to agreeing with the statement. Although short, the answer has profound consequences for owners of Tesla and the autonomous car industry as a whole.
AI4 and the Way to Unsupervised Autonomy
The AI4 chip of Tesla is a significant improvement over its predecessor, AI3 (HW3). It provides significantly more compute capability, enhanced camera inputs, and enhanced redundancy, important ingredients of autonomy with no human oversight. Musk says that AI4 will, in itself, reach self-driving safety levels many times better than humans; this is a confident stance, but it is consistent with Tesla’s view that vision-based systems, trained on a large scale, will eventually surpass human drivers.
Anyone using AI4 right now knows that better hardware is not needed for unsupervised driving. It’s incredibly good right now https://t.co/yUfniOoMf0

Notably, the remark by Musk indicates that the owners of the AI4-powered cars might not be required to install additional hardware in order to access unsupervised FSD once the release and approval take place. This is unlike the previous transitions, where the owners of Tesla vehicles were forced to upgrade their outdated hardware in order to remain compatible with newer versions of FSD.
Looking Ahead: AI5, AI6, and AI7
Musk also presented the long-term plan of Tesla for in-house AI smart chips. He claimed that the next AI5 chip will transform Tesla cars into near-perfection in terms of self-driving and also greatly expand the features of Optimus, a project of humanoid robots under Tesla. More than that, AI6 will have the capacity to support both Optimus and data center loads, pointing to Tesla having a broader goal of developing its AI beyond just vehicles.
The most ambitious statement, perhaps, is that of AI7, or Dojo 3. This generation will make space-based AI computers, the first time Musk has mentioned that placing data centers in orbit is a possible thing to do. This might ease cooling and energy limitations of data centers on Earth, which may be backed by SpaceX, although the idea is far-fetched and still years off when it comes to actual implementation.
Return and Strategic Importance of Dojo
The remarks of Musk also prove that Tesla is reinstating its Dojo program, which is the company’s initiative of AI training supercomputers. Dojo had been allegedly demoted last year, but its reemergence indicates the significance of large-scale training of AI to the autonomy targets of Tesla. The goal of Tesla developing its own chips and training infrastructure is to minimize the use of third-party hardware and make systems efficient and vision-based driving models specific.
Although regulatory approval is the most significant challenge to unsupervised FSD, the fact that Musk confirmed Tesla makes the main bet: that autonomy is a primarily software issue. Assuming that the cars powered by AI4 can really drive safer than humans by means of updating only, it would be a milestone, not just in the history of Tesla, but also in the history of transportation as a whole.
