Tesla completes new supercomputer Cortex to enhance self-driving technology

Tesla's Dojo supercomputer, designed to enhance its Full Self-Driving (FSD) technology, has seen significant developments since its initial announcement in 2019. While Dojo was expected to be crucial for training AI, Tesla has shifted focus to a new supercomputer called Cortex. In 2025, Tesla reported the completion of Cortex, which utilizes around 50,000 Nvidia GPUs. This new system is intended to improve FSD capabilities, as noted during Tesla's recent earnings call, where Dojo was not mentioned. Tesla's investment in AI infrastructure has reached approximately $5 billion, with plans for future expenditures remaining stable. The transition from Dojo to Cortex marks a notable change in Tesla's approach to AI training and development.
