Tesla, Inc. is a US electric-vehicle and energy company, led by CEO Elon Musk, whose AI activities span the Full Self-Driving (FSD) driver-assistance system, a commercial Robotaxi service, the Optimus humanoid-robot program, and custom AI-chip manufacturing plans. Its AI work is increasingly intertwined with Musk's other companies, principally SpaceX and xAI.
AI products and deployments
Tesla FSD is an advanced driver-assist system (Level 2+) using a vision-only sensor architecture, in contrast to the lidar-heavy stacks of Alphabet's Waymo and Baidu's Apollo Go (see Transportation — AI Deployment). Tesla rolled out its Robotaxi service in Miami on July 3, 2026 — its fifth city — following Waymo's April 2026 launch there (Source: theinformation.com).
FSD's supervision model drew scrutiny after a fatal June 2026 crash in Katy, Texas. On July 15, 2026 the National Transportation Safety Board released preliminary findings that the driver pressed the accelerator to 100%, manually overriding Full Self-Driving (Supervised) and reaching more than 70 mph on a 30-mph residential road before striking a house and killing a 76-year-old woman. The driver — whose search history included "Tesla FSD not aggressive enough 2026" — was charged with manslaughter, and the victim's family is suing him and Tesla for negligence (Source: techcrunch.com).
The head of the Optimus humanoid-robot program departed in June 2025 (see Transportation — AI Deployment).
Financials
Tesla missed profit expectations in its second-quarter 2026 results, reported July 22, 2026, with the shortfall tied to higher AI infrastructure spending; the stock fell 12.6% to $326.75 the following day as part of a broader selloff on AI-spending concerns (Source: staradvertiser.com; thestreet.com).
Terafab and custom silicon
On April 22, 2026, Tesla announced a $3 billion research fab partnership with Intel on Intel's 14A node for custom AI silicon (Source: intel.com). Tesla's organizational chart, detailed in July 6, 2026 reporting, shows the larger $55 billion Terafab semiconductor manufacturing project operating as a joint Tesla–SpaceX effort, amid growing expectations that Musk will propose merging the two companies (Source: theinformation.com). See Semiconductor Supply Chain.
SpaceX said on August 6, 2026 that it and Tesla will initially invest $16.8 billion to build Terafab in Grimes County, Texas. The stated rationale is closing the gap between global chip supply and the computing capacity the two companies expect to need, with their combined demand forecast to exceed 1 terawatt of computing power. Musk has said Terafab will handle every step of chip production, including design; Tesla broke ground in April 2026 on a precursor research fab at the North Campus of its Giga Texas plant (Source: reuters.com). A forecast exceeding 1 TW is roughly an order of magnitude above the 40–80 GW range projected for total US AI data-center power in 2030 on the central RAND scenario recorded at Compute Governance, and is a company projection rather than an independent estimate.
Figures for the total programme differ by source and are not binding. Reuters reported that a May 2026 filing proposed a $55 billion initial investment rising to $119 billion across additional phases, while Quartz reported the $16.8 billion first phase against a $119 billion ceiling and noted that the May IPO filing described Terafab as a "general framework" carrying no binding commitments; the $16.8 billion first phase is itself down from a $25 billion figure floated in March 2026 (Source: qz.com). The first phase covers more than 100 million square feet of logic, memory, packaging and testing and at least 3,000 jobs, with output intended to exceed a terawatt of compute a year for SpaceX and xAI data centres plus chips for Tesla's Optimus and Cybercab programmes.
SpaceX confirmed on August 10, 2026 that Terafab will be powered by newly built natural gas plants and "very large battery arrays," with no Tesla solar in the plan despite Tesla co-owning the project and selling solar, Powerwall and Megapack products. The plant sits on the site of a former coal-fired power plant (Source: electrek.co). The arrangement is an instance of the pattern described at Behind-the-Meter Power for Data Centers.
Internal AI use
Tesla told staff in a June 2026 internal memo that it would cap employee AI spending at $200 per week starting July 6, 2026 — excluding beta versions of xAI products — after engineers consumed "thousands of dollars' worth of tokens each week" following a months-long adoption push; many Tesla engineers reportedly prefer Anthropic's Claude to Grok despite the internal steer toward Musk-affiliated tools (Source: theinformation.com; electrek.co). On July 10, 2026, days after SpaceXAI and Cursor released Grok 4.5, Musk directed Tesla staff by memo to move to Grok, citing the model's lower token costs (Source: theinformation.com).
