Elon Musk’s OpenAI to battle in Dota 2 World Championship video game tournament
OpenAI, a research lab co-founded by Elon Musk, has developed a new breed of AI agents that are capable of playing Dota 2, a complex strategy game, in 5-on-5 multiplayer matches. OpenAI’s new bots have so far been able to beat amateur and semi-professional teams. With this accomplished, the research lab is now looking to bring its bots to The International, a prolific Dota 2 tournament, this coming August.
The new bots go by the name of OpenAI Five, a reference to the number of neural networks working together in the team. To train the neural networks, the AI has been playing roughly 180 years worth of gameplay every day using reinforcement learning. This enables the AI to learn the intricacies of the game, considering that it is far more complicated than board games like Chess and Go. Dota 2, for example, involves hiding data from players, preventing the system from perceiving the entire playing field at a given time.
The hardware employed by the research lab to train OpenAI Five is impressive. The five neural networks train through a scaled-up version of Proximal Policy Optimization running on 256 GPUs and 128,000 CPU cores. The same setup was adopted in a much smaller scale last year when OpenAI rolled out an artificial intelligence system that proved capable of beating the best Dota 2 players in the world in 1-on-1 matches.
Currently, however, OpenAI Five can only play the game with several restrictions. For one, the AI system can only use five of the 115 heroes available in the game. Skills such as Invisibility, Summons, and the placement of wards are also disabled. The research lab, however, hopes that through time, the neural networks would be able to play the game without any restrictions at all.
As could be seen in a recent video shared by the research lab, OpenAI Five is actually being received well by the Dota 2 community. Professional Dota 2 player Blitz, for one, noted that the bots are adopting strategies that are incredibly effective. In a match against OpenAI Five, Blitz, together with four employees of the research lab, put up a fight before getting dominated by the articificial intelligence. In a statement after the game, Blitz sheepishly stated that the bots capitalized on every small error he made during the match.
“I think the team fight aspect of the bot(s) was excellent. It didn’t mess up. When it came to coordination, it was some of the best pure team fighting because it felt like I was getting hammered every single time I made a mistake. I feel like normal humans don’t do that,” the professional Dota 2 player said.
So what’s the secret behind OpenAI Five? In a statement to The Verge, OpenAI CTO Greg Brockman noted that unlike human players, the bots have “no ego” when they play the game. The teamwork aspect of the bots was also trained by allowing them to work individually at first, then encouraging them to work together.
“The bots are totally willing to sacrifice a lane or abandon a hero for the greater good. For fun, we had a human drop in to replace one of the bots. We hadn’t trained them to do anything special, but he said he just felt so well-supported. Anything he wanted, the bots got him,” Brockman said.
Ultimately, Brockman is encouraged by OpenAI Five’s development so far. The research, after all, is motivated by the idea that if AI systems can be trained to perform complex tasks such as learning a game as intricate as Dota 2, it could eventually be used to solve equally complex real-world challenges. Some examples of real-world applications could be designing and managing a city’s transport structure, or the logistics of a massive business.
“This an exciting milestone, and it’s really because it’s about transitioning to real-life applications. If you’ve got a simulation of a problem and you can run it large enough scale, there’s no barrier to what you can do with this,” he said.

Tesla rolls out Steer-by-Wire improvements to Cybertruck

Tesla is rolling out some improvements to the Steer-by-Wire system on Cybertruck, which is one of the features exclusive to the vehicle as it is not active on any other vehicle in the company’s all-electric lineup.
Steer-by-wire is a steering system that turns the direction of wheels mechanically. It differs from vehicles with typical electric power steering systems in the way that those rely on the steering wheel column to transfer steering torque to the wheels.
There are a handful of EVs that use steer-by-wire, including the Cybertruck, Hummer EV, and Silverado EV. The latter two use a traditional steering column and only have steer-by-wire on their rear wheels, so they differ from the system the Cybertruck uses.

The system has made the massive Cybertruck have better steering, and although its size is large, it is one of the easier Tesla vehicles to steer through tight spaces — granted you have the room.
Tesla is making an improvement to the system, according to a new update that will roll out in the 2025.8.4 Software Update as the steering wheel is now going to give more realistic feedback by adapting to road surfaces, the company said (via Not a Tesla App):
“The steering wheel now gives you more realistic feedback, adapting to different road surfaces for a better driving experience.”
This feature will work alongside another improvement as the Cybertruck’s air suspension ride height is now adjustable through the Tesla App.

The changes from the update, in terms of the more realistic feedback, will improve the overall feel of the road for drivers, making for a better driving experience.

Rivian startup spinoff raises $105M in funding for micro EV production
Meet Also, Rivian’s micro EV spinoff, now a full-fledged startup with $105M in funding. It’s adapting Rivian’s tech for compact EVs.

Rivian’s skunkworks program has turned into a full-blown startup called Also. The new startup, which is separate from Rivian, raised $105 million from Eclipse Ventures. Also will focus on micromobility or the development of micro electric vehicles.
Also started within Rivian, aiming to figure out if the electric vehicle company’s technology could be condensed to fit smaller EVs, including vans, trucks, and SUVs. Eventually, the skunkworks program discovered it could, indeed, fit Rivian’s technology in smaller, more compact electric vehicles, but the project was bigger than Rivian.
“We’ve been taking the Rivian technology stack and adapting it to much smaller form factors and then coming up with some incredibly exciting embodiments of that technology in these very small form factors,” Rivian CEO RJ Scaringe told Reuters.
Rivian will always be part of Also. It holds a minority stake in Also and Rivian’s VP of future programs, Chris Yu, will be the startup’s president.
According to Scaringe, Also plans to debut its first vehicle designs later this year. One of the designs seems to be a bike, as Scringe described it having a seat, two wheels, and a screen with a few computers and a battery.
Also aims to start producing its flagship product by 2026 for customers in the United States and Europe. In addition, it plans to launch consumer and commercial vehicles made for Asia and South America.

Financial Times retracts report on Tesla’s alleged shady accounting
“Turns out FT can’t do finance,” Tesla CEO Elon Musk quipped on X.

The Financial Times has issued a retraction for an article it recently published that accused the electric vehicle maker of shady accounting practices.
The FT’s retraction has been appreciated by the electric vehicle community in social media, though many highlighted the fact that the publication’s initial erroneous allegations have already been spread across numerous other media outlets.
The Allegations
In an article published on March 19, the Financial Times pointed out that if one were to compare “Tesla’s capital expenditure in the last six months of 2024 to its valuation of the assets that money was spent on,” “$1.4 billion appears to have gone astray.”
The FT article highlighted that Tesla reported spending $6.3 billion on “purchases of property and equipment excluding finance leases, net of sales” in the second half of 2024. However, in that period, the company’s property, plant, and equipment only rose by $4.9 billion. As noted by members of the r/Accounting subreddit, this appeared to be the basis of the FT‘s article, which seemed careless at best.
Unfortunately, the publication’s allegations were quickly echoed by other news outlets, many of which proceeded to accuse Tesla of implementing shady accounting practices.
The Retraction
In its retraction, the Financial Times explained that Tesla’s payments for assets already purchased and the possible disposal of depreciated property could help explain the alleged discrepancy in the company’s numbers. With these in consideration, the publication noted that the “crack we’re left with at Tesla is now small enough — just under half a billion dollars — to be filled with some combination of foreign exchange movements, non-material asset write-offs, or the sale of machinery or equipment close to its not-fully depreciated value.”
“As we sound the Alphaville bugle while lowering this particular red flag, one unavoidable conclusion is that at a certain point it’s necessary to trust the auditor’s judgment,” the publication noted.
Tesla CEO Elon Musk has responded to the Financial Times‘ retraction, commenting, “Turns out FT can’t do finance” in a post on social media platform X.
