Core Viewpoint - The discontinuation of Tesla's Dojo project highlights the challenges and limitations of self-developed training chips in the AI industry, emphasizing that most companies cannot replicate the success of a few exceptions like NVIDIA [1][21][22]. Summary by Sections Dojo Project Overview - Dojo was Tesla's self-developed training system aimed at real-world scenario modeling, first introduced by Elon Musk in April 2019, with expectations for significant capabilities by 2023 [3][4]. - The project aimed for a systematic expansion to achieve over 1 ExaFLOP of ML computing power but ultimately faced project termination [3][4]. Market Expectations and Reality - Initial market expectations for Dojo were high, with estimates suggesting it could add approximately $500 billion in value to Tesla [4]. - By 2025, Musk indicated that the goal for Dojo 2 was to match around 100,000 H-equivalent units, but the project was eventually halted [4]. Talent Departure and Strategic Shift - Key personnel departures, including Jim Keller and Peter Bannon, indicated challenges within the Dojo project, leading to its closure [4][7]. - Tesla shifted its focus to purchasing mature GPU platforms, primarily from NVIDIA, to enhance training efficiency and speed [7][5]. Challenges of Self-Developed Training Chips - The difficulty of developing self-training chips stems from ecosystem and software barriers, system engineering and supply chain issues, demand and cash flow rhythms, and opportunity costs [9][10][12][13]. - Companies like Google and AWS have succeeded in this area due to stable, large-scale self-use training demands, which are not easily replicable by automotive or application companies [15]. NVIDIA's Competitive Advantage - NVIDIA's success is attributed to its comprehensive system capabilities, including hardware, networking, software, and delivery, which create a robust ecosystem that is difficult for competitors to match [17][19]. - The integration of various components into a cohesive AI infrastructure allows NVIDIA to offer immediate usability, making it a preferred choice over self-developed solutions [19][21]. Conclusion - The closure of the Dojo project signifies that Tesla did not lose to a superior chip but rather to a more robust industrial system, reinforcing the notion that self-developed training chips are not a viable path for most companies [21][22].
