Tesla Dojo Supercomputer Scrapped: Elon Musk Shifts to Nvidia & Samsung Chips Ending In-House AI $500B Dream | Autonomous Driving Strategy Shift

Key Takeaways

  • Tesla disbanded its entire Dojo supercomputer team on August 7, 2025, ending the in-house chip development project 
  • Peter Bannon, Dojo's team leader, left the company along with 20 other key engineers 
  • Musk pivots to AI5 and AI6 chips manufactured by TSMC and Samsung instead of custom Dojo processors
  • Tesla signed a $16.5 billion deal with Samsung for AI6 chip production 
  • The company will rely more heavily on Nvidia, AMD, and Samsung for AI processing power 
  • Remaining Dojo team members get reassigned to other Tesla data center projects 
  • DensityAI, a startup formed by former Dojo employees, emerges as competition


The Death of a Dream Machine

Tesla killed its Dojo supercomputer project this week. CEO Elon Musk ordered the shutdown after a mass exodus of talent from the Dojo team to a competing startup. Peter Bannon packed his bags and walked out the door. The man who led Tesla's most ambitious AI hardware project just became another casualty in Silicon Valley's talent wars.

The timing stings. Dojo went into production in July 2023 with one goal: process millions of terabytes of video data from Tesla's 4+ million cars. Two years of work vanished faster than a Tesla on autopilot hitting a concrete barrier.

Musk's X post late Wednesday night confirmed what industry insiders already knew. The dream of building custom AI chips died hard. "The Tesla AI5, AI6, and subsequent chips will be excellent for inference and at least pretty good for training. All effort is focused on that," Musk posted on X.

The remaining Dojo engineers get shuffled around like deck chairs on the Titanic. The remaining team members will be reassigned to other data center and compute projects within Tesla. Nobody talks about what happens to projects that lose their champions, they die quiet deaths in corporate purgatory.

Twenty Engineers Walk Into a Startup

The disbanding of Tesla's Dojo efforts follows the departure of around 20 workers, who left the automaker to start their own AI company dubbed DensityAI focused on data center services for industries. These weren't junior developers looking for stock options. These were the architects who understood wafer-level processing better than most people understand their morning coffee.

DensityAI emerges from stealth mode soon. The new startup is reportedly coming out of stealth soon. Former Tesla engineers building data center infrastructure for other companies. The irony tastes bitter , Tesla trains its own competition then watches them walk out the front door.

Brain drain hits different when you're trying to build the future. The automaker invested heavily in talent, hiring top chip architects across the industry. Tesla recruited these engineers from Nvidia, AMD, and other chip giants. Now they're gone, taking institutional knowledge with them.

The startup probably offers better work-life balance. Maybe equity that actually matters. Maybe just the chance to build something without Musk changing direction every quarter. Sometimes the grass really is greener, especially when it's your own grass.

The Nvidia Surrender

Tesla will increase reliance on external tech partners like AMD and NVIDIA. Musk waved the white flag. The company that wanted to build everything in-house now depends on the same suppliers everyone else uses. It was meant to cut dependency on companies like Nvidia and AMD by building better AI accelerator chips in-house.

Independence costs more than most companies can afford. Custom silicon requires years of development and hundreds of millions in upfront costs. These chips were intended to power self-driving systems, robots, and data centers. Tesla bet big on vertical integration and lost.

Nvidia stock probably bumped up a few points when the news broke. Jensen Huang's company maintains its stranglehold on AI processing. Every company that tries to break free eventually comes crawling back. Apple tried with their own chips. Google built TPUs. Amazon developed Graviton processors. Most still buy Nvidia for the heavy lifting.

The economics make sense even when the optics don't. Buying proven chips costs less than developing unproven ones. Tesla learned this lesson the expensive way.

AI5 and AI6 Emerge from the Ashes

TSMC will produce the AI5 processor for next-generation Tesla vehicles starting in 2025, whereas Samsung Foundry will produce its successor, the AI6 processors, sometime towards the end of the decade. Musk didn't abandon custom chips entirely. He just changed the manufacturing strategy.

Musk has stated that AI5 chips will begin production at the end of 2026, suggesting AI6 will follow. The timeline stretches longer than a California traffic jam. Two chips spanning five years sounds like normal semiconductor development cycles , not the rapid iteration Tesla promised with Dojo.

Tesla last month signed a $16.5 billion deal with Samsung to make its AI6 inference chips, a chip design that promises to scale from powering FSD and Tesla's Optimus humanoid robots all the way to high-performance AI training in data centers. Sixteen billion dollars buys a lot of silicon. Samsung gets a massive contract. Tesla gets chips designed by committee instead of revolutionary wafer-level processors.

Tesla AI6 will be built in the US on Samsung's 2nm foundry node, with mass production slated for 2028. Three years from now feels like a lifetime in tech cycles. GPT-10 will probably be running the world by then.

The Wafer-Level Architecture Experiment Dies

This goal led to a considerably different architecture than conventional supercomputer designs. Dojo wasn't just another AI chip. The architecture broke conventional wisdom about how processors should work. Wafer-level processing meant treating entire silicon wafers as single computational units instead of cutting them into individual chips.

The concept made theoretical sense. Video processing from millions of Tesla vehicles requires massive parallel computation. Traditional chips hit bandwidth bottlenecks when shuffling data between processors. Wafer-level design eliminates those bottlenecks by putting everything on the same piece of silicon.

Implementation proved harder than theory. Yield rates on wafer-level processors make traditional chip manufacturing look easy. One defect can kill an entire wafer worth millions of dollars. Testing becomes a nightmare when you can't probe individual chips before packaging.

Tesla's engineers probably knew these challenges going in. They bet on solving manufacturing problems that stumped other companies for decades. The bet didn't pay off. Sometimes revolutionary ideas stay theoretical for good reasons.

The Economics of Custom Silicon

Building custom processors costs serious money. Initial development runs tens of millions before you cut the first wafer. Manufacturing setup costs millions more. Testing equipment costs millions beyond that. Most companies buy off-the-shelf chips because the economics don't work otherwise.

Tesla thought volume would solve the economics problem. Tesla operates several massively parallel computing clusters for training. Millions of vehicles need inference chips. Optimus robots need processing power. The combined demand seemed large enough to justify custom silicon.

The math probably worked on paper. Real-world development proved more expensive than spreadsheets predicted. Engineering talent costs more than budgets account for. Manufacturing partners demand minimum volumes that strain even Tesla's scale. Timeline delays multiply costs faster than compound interest.

Musk cut losses before they got worse. Smart business decision even if it stings the ego. Sometimes the brave choice is admitting when revolutionary ideas hit immovable economic reality.

What This Means for Full Self-Driving

It is used for training Tesla's machine learning models to improve its Full Self-Driving (FSD) advanced driver-assistance system. Dojo's primary mission was making FSD work better. The supercomputer processed video from millions of Tesla vehicles to train neural networks that could handle edge cases human drivers never encounter.

FSD development continues without Dojo. Tesla still collects massive amounts of driving data. The company still runs training clusters. "The Tesla AI5, AI6, and subsequent chips will be excellent for inference and at least pretty good for training." Musk sounds confident that conventional approaches will work fine.

The transition might actually help FSD development. Dojo's custom architecture required specialized software that took years to optimize. Standard Nvidia and AMD chips work with mature software stacks that thousands of engineers already understand. Development velocity could increase even if raw performance decreases.

FSD timelines won't change much. The technology faces bigger challenges than processing power. Computer vision still struggles with snow, construction zones, and aggressive human drivers. More compute helps but doesn't solve fundamental perception problems.
