Elon Musk details Neuralink’s August 28 event, hints toward future developments
Neuralink’s Elon Musk hinted toward some of the possible developments of the company’s August 28th event, which will give updates on the progress engineers have made toward developing State-of-the-Art neurological technologies.
Of these updates, Musk stated that the August 28th event would show a real-time demonstration of neurons in the human brain firing. One of the core developments in Neuralink’s plans is to begin working toward the idea that human movement can be recovered by using some of the company’s technology.

To restore some human functionalities, neurons in a damaged brain must be recovered and given the ability to move and function normally again. Neurons are nerve cells that are responsible for communicating with other cells through synapses.
To work correctly, neurons must fire at different times, depending on the activity that is being performed. However, those with handicaps or neurological diseases lose functionality of these neurons. Neuralink’s technology aims to restore the use and integrity of neurons through an implantable chip in the human skull.
During an episode of the Joe Rogan Experience podcast, Musk talked about Neuralink in detail. The Silicon Valley entrepreneur stated that with Neuralink technology, the human brain could overcome issues such as Alzheimer’s disease, strokes, and other illnesses. Additionally, lost limb function, problems with eyesight and hearing, and lost human movement could all be solved by installing a Neuralink chip in the skull.
Neuralink has tested this technology in the past. In July 2019, the company held a live-streamed event in California where a series of “flexible threads” were inserted into the brain and transferred high volumes of data with over 3,000 available electrodes. The tests have been performed on animals with an 87% success rate thus far.
Additionally, Musk indicated that Neuralink could eventually dive into spinal cord injuries by developing technology that would be responsible for fixing some of the harshest injuries that a human can endure.
Musk said that it should be possible to create a neural shunt from the motor cortex of the brain that controls the planning and control of voluntary movements to microcontrollers that are located within human muscle groups. The development of this technology could ultimately resolve paraplegic and quadriplegic patients who have lost motor skills within their limbs.
Yes, should be possible to create a neural shunt from motor cortex to microcontrollers in muscle groups & restore movement even if someone has a fully severed spinal cord. First part has already been demonstrated with Utah array, but not as an outpatient device.

Ultimately, Neuralink’s possible uses are possibly endless. Musk believes that the implementation of a chip could help with hearing disabilities and deaf patients who are hard of hearing. Neuralink technology could help “extend the range of hearing beyond normal frequencies and amplitudes” as well.
It may be some time until we see Neuralink used on human beings because the company still has to go through ordinary Food and Drug Administration hoops. Until then, Neuralink engineers will continue to develop the technology. The August 28th event could prove to be a significant step forward in the case of neurological disorder treatment.

Tesla confirms that work on Dojo 3 has officially resumed
“Now that the AI5 chip design is in good shape, Tesla will restart work on Dojo 3,” Elon Musk wrote in a post on X.
Tesla has restarted work on its Dojo 3 initiative, its in-house AI training supercomputer, now that its AI5 chip design has reached a stable stage.
Tesla CEO Elon Musk confirmed the update in a recent post on X.
Tesla’s Dojo 3 initiative restarted
In a post on X, Musk said that with the AI5 chip design now “in good shape,” Tesla will resume work on Dojo 3. He added that Tesla is hiring engineers interested in working on what he expects will become the highest-volume AI chips in the world.
“Now that the AI5 chip design is in good shape, Tesla will restart work on Dojo3. If you’re interested in working on what will be the highest volume chips in the world, send a note to AI_Chips@Tesla.com with 3 bullet points on the toughest technical problems you’ve solved,” Musk wrote in his post on X.
Musk’s comment followed a series of recent posts outlining Tesla’s broader AI chip roadmap. In another update, he stated that Tesla’s AI4 chip alone would achieve self-driving safety levels well above human drivers, AI5 would make vehicles “almost perfect” while significantly enhancing Optimus, and AI6 would be focused on Optimus and data center applications.
Musk then highlighted that AI7/Dojo 3 will be designed to support space-based AI compute.
Tesla’s AI roadmap
Musk’s latest comments helped resolve some confusion that emerged last year about Project Dojo’s future. At the time, Musk stated on X that Tesla was stepping back from Dojo because it did not make sense to split resources across multiple AI chip architectures.
He suggested that clustering large numbers of Tesla AI5 and AI6 chips for training could effectively serve the same purpose as a dedicated Dojo successor. “In a supercomputer cluster, it would make sense to put many AI5/AI6 chips on a board, whether for inference or training, simply to reduce network cabling complexity & cost by a few orders of magnitude,” Musk wrote at the time.
Musk later reinforced that idea by responding positively to an X post stating that Tesla’s AI6 chip would effectively be the new Dojo. Considering his recent updates on X, however, it appears that Tesla will be using AI7, not AI6, as its dedicated Dojo successor. The CEO did state that Tesla’s AI7, AI8, and AI9 chips will be developed in short, nine-month cycles, so Dojo’s deployment might actually be sooner than expected.

Elon Musk’s xAI brings 1GW Colossus 2 AI training cluster online
Elon Musk shared his update in a recent post on social media platform X.
xAI has brought its Colossus 2 supercomputer online, making it the first gigawatt-scale AI training cluster in the world, and it’s about to get even bigger in a few months.
Elon Musk shared his update in a recent post on social media platform X.
Colossus 2 goes live
The Colossus 2 supercomputer, together with its predecessor, Colossus 1, are used by xAI to primarily train and refine the company’s Grok large language model. In a post on X, Musk stated that Colossus 2 is already operational, making it the first gigawatt training cluster in the world.
But what’s even more remarkable is that it would be upgraded to 1.5 GW of power in April. Even in its current iteration, however, the Colossus 2 supercomputer already exceeds the peak demand of San Francisco.
Commentary from users of the social media platform highlighted the speed of execution behind the project. Colossus 1 went from site preparation to full operation in 122 days, while Colossus 2 went live by crossing the 1-GW barrier and is targeting a total capacity of roughly 2 GW. This far exceeds the speed of xAI’s primary rivals.
Funding fuels rapid expansion
xAI’s Colossus 2 launch follows xAI’s recently closed, upsized $20 billion Series E funding round, which exceeded its initial $15 billion target. The company said the capital will be used to accelerate infrastructure scaling and AI product development.
The round attracted a broad group of investors, including Valor Equity Partners, Stepstone Group, Fidelity Management & Research Company, Qatar Investment Authority, MGX, and Baron Capital Group. Strategic partners NVIDIA and Cisco also continued their support, helping xAI build what it describes as the world’s largest GPU clusters.
xAI said the funding will accelerate its infrastructure buildout, enable rapid deployment of AI products to billions of users, and support research tied to its mission of understanding the universe. The company noted that its Colossus 1 and 2 systems now represent more than one million H100 GPU equivalents, alongside recent releases including the Grok 4 series, Grok Voice, and Grok Imagine. Training is also already underway for its next flagship model, Grok 5.

Musk details AI chip roadmap
In his post, Elon Musk stated that Tesla’s AI5 chip design is “almost done,” while AI6 has already entered early development. Musk added that Tesla plans to continue iterating rapidly, with AI7, AI8, AI9, and future generations targeting a nine-month design cycle.
He also noted that Tesla’s in-house chips could become the highest-volume AI processors in the world. Musk framed his update as a recruiting message, encouraging engineers to join Tesla’s AI and chip development teams.
Tesla community member Herbert Ong highlighted the strategic importance of the timeline, noting that faster chip cycles enable quicker learning, faster iteration, and a compounding advantage in AI and autonomy that becomes increasingly difficult for competitors to close.
AI5 manufacturing takes shape
Musk’s comments align with earlier reporting on AI5’s production plans. In December, it was reported that Samsung is preparing to manufacture Tesla’s AI5 chip, accelerating hiring for experienced engineers to support U.S. production and address complex foundry challenges.
Samsung is one of two suppliers selected for AI5, alongside TSMC. The companies are expected to produce different versions of the AI5 chip, with TSMC reportedly using a 3nm process and Samsung using a 2nm process.
Musk has previously stated that while different foundries translate chip designs into physical silicon in different ways, the goal is for both versions of the Tesla AI5 chip to operate identically. AI5 will succeed Tesla’s current AI4 hardware, formerly known as Hardware 4, and is expected to support the company’s Full Self-Driving system as well as other AI-driven efforts, including Optimus.
