Tesla Dojo: The rise and fall of Elon Musk’s AI supercomputer

For years, Elon Musk has spoken of the promise of Dojo, the AI supercomputer that was supposed to be the cornerstone of Tesla’s AI ambitions. It was important enough to Musk that in July 2024, he said the company’s AI team would “double down” on Dojo in the lead-up to Tesla’s robotaxi reveal, which happened in October. After six years of hype, Tesla decided last month to shut down Dojo and disband the team behind the supercomputer in August 2025. Within weeks of projecting that Dojo 2, Tesla’s

Tesla’s Dojo, a timeline

techcrunch.com Rebecca Bellan 2025-10-21 10:39:01

Elon Musk doesn’t want Tesla to be just an automaker. He wants Tesla to be an AI company, one that’s figured out how to make cars drive themselves. Crucial to that mission was Dojo, a custom-built supercomputer designed by Tesla to train its Full Self-Driving (FSD) neural networks. FSD isn’t actually fully self-driving; it can perform some automated driving tasks, but still requires an attentive human behind the wheel. But Tesla thinks with more data, more compute power and more training, it ca

The Default Trap: Why Anthropic's Data Policy Change Matters

Read the terms of service. Don’t make assumptions. Don’t pick defaults. Yesterday, Anthropic quietly flipped a switch. If you're a Claude user, your conversations are now training data unless you actively say no. Not when you give feedback. Not when you explicitly consent. By default, from day one. Here's what changed: Previously, Claude didn't train on consumer chat data without your explicit thumbs up or down. Clean, simple, respectful. Now? Everything you type becomes model training fodder

With new in-house models, Microsoft lays the groundwork for independence from OpenAI

Microsoft has introduced AI models that it trained internally and says it will begin using them in some products. This announcement may represent an effort to move away from dependence on OpenAI, despite Microsoft's substantial investment in that company. It comes more than a year after insider reports revealed that Microsoft was beginning work on its own foundational models. A post on the Microsoft AI blog describes two models.

While these safeguards work best in common, short exchanges, we’ve learned over time that they can sometimes become less reliable in long interactions where parts of the model’s safety training may degrade,” an OpenAI spokesperson told Gizmodo.

Beyond GDPR security training: Turning regulation into opportunity

By Eirik Salmi, System Analyst at Passwork Even though 88% of businesses spend over €1 million on GDPR compliance and 40% invest up to €10 million, 80% of their employees still ignore basic password security practices. The formal risk is obvious: GDPR fines can reach up to €20 million or 4% of global annual turnover. The informal one is quieter but often far more damaging: lost trust, declining customer loyalty, and disrupted operations. In 2024, European regulators issued fines exceeding €1.2

An inner-speech decoder reveals some mental privacy issues

Most experimental brain-computer interfaces (BCIs) that have been used for synthesizing human speech have been implanted in the areas of the brain that translate the intention to speak into the muscle actions that produce it. A patient has to physically attempt to speak to make these implants work, which is tiresome for severely paralyzed people. To go around it, researchers at the Stanford University built a BCI that could decode inner speech—the kind we engage in silent reading and use for al

Starlink is absolutely critical to Ukraine’s ability to continue in the fight against Russia. It’s how troops in battle zones stay connected with faraway HQs; it’s how many of the drones essential to Ukraine’s survival hit their targets; it’s even how soldiers stay in touch with spouses and children back home. However, Donald Trump’s fickle foreign policy and reports suggesting Elon Musk might remove Ukraine’s access to the services have cast the technology’s future in the country into doubt.
