The official account of Tesla's artificial intelligence team on X has been renamed to Tesla Super Intelligence, with the username changed from Tesla_AI to TeslaSI, and the original username no longer exists. The renaming occurred on the evening of October 8, without a separate announcement from the account itself.

Senior engineer Yun-Ta Tsai's public profile has been updated to Senior Staff Engineer at TeslaSI, and at 7:02 PM Pacific Time, he stated that Tesla Super Intelligence is the only team focused on solving real-world intelligence, with a path from large-scale bits to atoms. Elon Musk retweeted this post about an hour later. Reports indicate that the account has over 510,000 followers.

The renaming took place after U.S. President Donald Trump signed Executive Order 14434 on September 29. The order, titled Inaugurating the Era of Super Intelligence, requires executive departments to use Super Intelligence and SI instead of Artificial Intelligence and AI in official correspondence, public communications, websites, reports, and policy documents, without acknowledging the latter terms. The order does not mandate changes to existing regulations, presidential actions, contracts, appropriations, and historical documents, nor does it constrain private enterprises.

The executive order defines SI as the artificial intelligence technologies and systems covered under Section 9401(3) of Title 15 of the U.S. Code. The related definition work must be completed within 60 days of the order's issuance, with a deadline of November 28.

On October 4, Elon Musk stated that he would no longer use AI and that referring to it as SI is better, confirming that SpaceXAI will also be renamed to SpaceXSI, while stating that SpaceX is a superintelligence company. SpaceX has acquired xAI this year, and if the company name is finalized, it will be the second name change for that business within the year. Tesla previously converted its $2 billion investment in xAI into minority equity in SpaceX, thus indirectly holding related assets.

The account renaming does not change deliveries, orders, or capital expenditures; it is a branding and terminology event. Buyers are trading on whether the narratives around autonomous driving, robotics, and self-developed chips are more aligned with federal terminology; sellers are trading on the fact that the name change does not rewrite the regulatory path or statutory definitions for FSD. Currently, there is no verifiable influx of funds into Tesla stock driven solely by this name change. Beneficiaries are the engineering teams linking superintelligence to vehicles and robots; those under pressure are the federal contracting systems that still sign contracts, draft regulations, and procure documents under AI, as the new nomenclature runs parallel to existing texts.

On the industry side, Safe Superintelligence, Meta Superintelligence Labs, and Microsoft's MAI Superintelligence Team had already used the term superintelligence before the executive order. X.AI LLC registered SpaceXSI.com on July 25, 2025. Tesla's account is the first within Musk's ecosystem to complete the public replacement, while the company name and branding for SpaceXAI have yet to be finalized.
