Google DeepMind has unveiled new research highlighting an AI agent that's able to carry out a swath of tasks in 3D games it hasn't seen before. The team has long been experimenting with AI models that can win in the likes of Go and chess, and even learn games without being told their rules. Now, for the first time, according to DeepMind, an AI agent has shown it's able to understand a wide range of gaming worlds and carry out tasks within them based on natural-language instructions.

The researchers teamed up with studios and publishers such as Hello Games (No Man's Sky), Tuxedo Labs (Teardown) and Coffee Stain (Valheim and Goat Simulator 3) to train the Scalable Instructable Multiworld Agent (SIMA) on nine games. The team also used four research environments, including one built in Unity in which agents are instructed to form sculptures using building blocks. This gave SIMA, described as "a generalist AI agent for 3D virtual settings," a range of environments and settings to learn from, with a variety of graphics styles and perspectives (first- and third-person). 

"Each game in SIMA’s portfolio opens up a new interactive world, including a range of skills to learn, from simple navigation and menu use, to mining resources, flying a spaceship or crafting a helmet," the researchers wrote in a blog post. Learning to follow directions for such tasks in video game worlds could lead to more useful AI agents in any environment, they noted.

The researchers recorded humans playing the games and noted the keyboard and mouse inputs used to carry out actions. They used this information to train SIMA, which has "precise image-language mapping and a video model that predicts what will happen next on-screen." The AI is able to comprehend a range of environments and carry out tasks to accomplish a certain goal.

The researchers say SIMA doesn't need a game's source code or API access — it works on commercial versions of a game. It also needs just two inputs: what's shown on screen and directions from the user. Since it uses the same keyboard and mouse input method as a human, DeepMind claims SIMA can operate in nearly any virtual environment.

The agent is evaluated on hundreds of basic skills that can be carried out within 10 seconds or so across several categories, including navigation ("turn right"), object interaction ("pick up mushrooms") and menu-based tasks, such as opening a map or crafting an item. Eventually, DeepMind hopes to be able to order agents to carry out more complex and multi-stage tasks based on natural-language prompts, such as "find resources and build a camp."

In terms of performance, SIMA fared well based on a number of training criteria. The researchers trained the agent in one game (let's say Goat Simulator 3, for the sake of clarity) and got it to play that same title, using that as a baseline for performance. A SIMA agent that was trained on all nine games performed far better than an agent that trained on just Goat Simulator 3.

What's especially interesting is that a version of SIMA that was trained in the eight other games then played the other one performed nearly as well on average as an agent that trained just on the latter. "This ability to function in brand new environments highlights SIMA’s ability to generalize beyond its training," DeepMind said. "This is a promising initial result, however more research is required for SIMA to perform at human levels in both seen and unseen games."

For SIMA to be truly successful, though, language input is required. In tests where an agent wasn't provided with language training or instructions, it (for instance) carried out the common action of gathering resources instead of walking where it was told to. In such cases, SIMA "behaves in an appropriate but aimless manner," the researchers said. So, it's not just us mere mortals. Artificial intelligence models sometimes need a little nudge to get a job done properly too.

DeepMind notes that this is early-stage research and that the results "show the potential to develop a new wave of generalist, language-driven AI agents." The team expects the AI to become more versatile and generalizable as it's exposed to more training environments. The researchers hope future versions of the agent will improve on SIMA's understanding and its ability to carry out more complex tasks. "Ultimately, our research is building towards more general AI systems and agents that can understand and safely carry out a wide range of tasks in a way that is helpful to people online and in the real world," DeepMind said.

The non-fungible token (NFT) bubble burst quite some time ago, but the US Government has only just published a report looking into the surrounding legal framework. The study, carried out jointly by the US Copyright Office (USCO) and the Patent and Trademark Office (USPTO) following a 2022 request by the Senate, determined that current intellectual property laws are robust enough to deal with copyright or trademark infringement in NFTs. The agencies also determined that although there are some benefits to the tokens, "trademark infringement and misuse is prevalent on NFT marketplaces."

As a reminder, an NFT is a digital certificate of authenticity conferring ownership of a collectible, such as an artwork or piece of music. It's effectively a verified link to a piece of media which may or may not live on the blockchain, but whoever owns the destination of an NFT's URL can change the media it points to at any time. In one notable case in 2021, Signal founder Moxie Marlinspike created an NFT that he promised would appear to be a poop emoji when someone bought it.

The offices noted that NFTs and associated smart contracts can aid trademark owners in managing, licensing and transferring IP rights. Those who weighed in on the issue in public comments pointed out that NFTs can help artists make money from future sales of their work too. That's not inherently a bad thing, even if a large swath of NFT art is butt-ugly.

However, the study noted "widespread concern that NFT buyers and sellers do not know what IP rights are implicated in the creation, marketing and transfer of NFTs and that NFTs may be used to facilitate copyright or trademark infringement."

The report notes that the decentralized nature of NFTs and blockchain networks complicates any attempts to enforce trademarks. "While some individual NFT platforms have developed protocols to help trademark owners enforce their rights, there is no centralized authority that requires all platforms to do so," the report reads. "There are also no cross-platform mechanisms to allow trademark owners to identify and take down infringing content, settle trademark-related disputes involving blockchain-based domain names, or confirm that sellers own the trademark rights associated with the assets they offer."

With all of that in mind, the offices said that educating the public about NFTs could help ensure a better understanding and awareness of the tokens and how they work. Still, they recommended in their report to Congress that the current use of NFTs doesn't require changes to current IP laws. They also noted that "incorporating NFTs into their registration and recordation practices is not necessary or advisable at this time." In other words, they don't think they should have to deal with NFTs either.

Days after Apple started allowing iOS users in the EU to use third-party app stores, the company has announced more changes related to how developers can distribute their apps. Most significantly, those who meet certain criteria will be able to let users download apps from their websites.

The Web Distribution option, which will be available this spring, will effectively let developers bypass the app ecosystem entirely for their own apps. To be eligible, devs will need to opt in to new App Store rules that see them pay a fee for each user install after certain thresholds and be an Apple Developer Program member that’s been in good standing for at least two years. They’ll need to “have an app that had more than one million first annual installs on iOS in the EU in the prior calendar year” among other criteria, per a support document.

By setting certain rules for supporting downloads from the web, Apple will be hoping to minimize the risk that users will be installing sketchy apps, such as ones containing malware or those that support piracy. Still, given the criticism levied against the company for seemingly only sticking to the letter of the EU’s Digital Markets Act and not its spirit, the fact that the company is exerting control over app downloads from the web may come under scrutiny too.

In addition, as 9to5Mac notes, Apple is now allowing developers to run app marketplaces that solely contain their own apps. Previously, they were required to offer apps from other devs. As such, this means the likes of Epic Games, Xbox and Meta can have iOS app marketplaces that only include their own apps and games.

Last but not least, developers will have more flexibility over how they can direct users to an external webpage to complete a transaction for digital goods and services. Apple had provided design templates for in-app promotions, discounts and deals, but those are now optional as of today. That means the likes of Spotify and Netflix can now design links out to their websites (and potentially avoid the 30 percent cut Apple takes of subscriptions from app-based signups).

It's been a busy several few months for fighting game fans between the likes of Street Fighter 6, Tekken 8 and Mortal Kombat 1 arriving. Another game is entering (or more accurately re-entering) the fray as Warner Bros' platform fighter MultiVersus will return on May 28. It will be available on PS4, PS5, Xbox One, Xbox Series X/S, Steam and the Epic Games Store.

MutliVersus is Warner Bros' take on the Super Smash Bros. series. The aim is to weaken enemies enough to knock them off of a platform. Instead of controlling the likes of Mario, Link, Pikachu and Sephiroth, the roster is made up of characters from across WB properties, including DC Comics, its movies (hence the inclusion of LeBron James from Space Jam: A New Legacy) and even HBO. It's an enjoyable two vs. two take on the format.

The free-to-play game debuted in open beta in July 2022 and it was an instant hit. It brought in 20 million players in its first month. However, the player count dwindled quickly (at least on PC) amid complaints of a lack of updates and new characters. Developer Player First Games said last March that it would take the servers offline in June so it could work on the game ahead of its full release this year. One aspect of this that angered some fans was the fact many spent money on the game to unlock characters and cosmetics, only for it to go offline for what turned out to be another 10 months.

Along with the full release date, game director Tony Hyunh announced some of the updates to MultiVersus. There will, of course, be new characters. Hyunh didn't reveal any of the fresh faces, but I have my fingers crossed for a couple of names from Succession and The Last of Us showing up, just because. You can also expect more stages and fresh attacks for each character. We'll learn more details in the lead up to the release date.

Player First Games rebuilt the game from the ground up in Unreal Engine 5 to improve character lighting and the visuals. Hyunh says the team incorporated new rollback netcode to minimize lag for online play and to ensure consistent performance. There will also be a player versus environment mode that will allow you to play the game without having to square off against other players.

MultiVersus is returning just after Warner Bros. Discovery announced plans to focus more on live-service, mobile and free-to-play games with a long-tail rather than single-player experiences. That's despite the disappointing performance of Suicide Squad: Kill the Justice League (a live-service title) and colossal commercial success of Hogwarts Legacy, which sold 22 million copies last year.

According to Elon Musk, xAI will open source its Grok chatbot. The founder of the company, whose AI assistant is available to Premium+ subscribers on X, hasn't revealed any other details about the decision, which is slated to take effect this week.

It's hardly the first time a Musk company has opened up access to its knowhow. Tesla open sourced its patents a decade ago, and now practically every major car manufacturer has adopted its electric vehicle charging connector. X, meanwhile, published the code that powers its "For You" algorithmic feed last year, though we didn't learn much from it.

As The Wall Street Journal points out, Musk may be hoping that, by letting third-party developers and researchers dig into Grok's code, there could could be an increased uptake of the model. The developer community may also provide feedback that could be used to improve Grok.

Open sourcing Grok may also be seen as a dig at OpenAI. Earlier this month, Musk sued the ChatGPT maker, a company he co-founded, for allegedly prioritizing profits and ditching its original not-for-profit mission. The suit described OpenAI as a “closed-source de facto subsidiary” of Microsoft, which has invested $13 billion into OpenAI and has a 49 percent stake. OpenAI bit back at Musk by claiming that he wanted to merge the company with Tesla and become its CEO.

Update 3/11/24: The PS5 bundle deal that we originally found at GameStop is now available at Amazon, Target and Walmart as well.

If you've been on the fence about snagging a PS5 and have been intrigued by Marvel's Spider-Man 2, now's a good time to considering picking up the console. You can get a bundle with either the digital or standard edition of the PS5 with the game for $50 off. That brings the bundle with the digital version of the console down to $400, while the standard-edition pairing will run you $450.

Spider-Man 2 is an excellent way to get your PS5 games collection started, particularly for new PS5 owners. It's one of our favorite games of last year and we felt it was both bigger and better than the first game in the series. If you'd prefer to play Marvel's Spider-Man and Marvel's Spider-Man: Miles Morales before diving into the latest entry (both are great games too), you can check them out through the PlayStation Plus subscription service on the Extra and Premium tiers. However, some folks may now be joining the PlayStation club after already playing those two games on PC — I wouldn't want to wait too long for Spider-Man 2 to arrive on PC after first playing the previous entries there either.

When it comes to a modern gaming system, you can't go far wrong with the PS5. It's our pick for the best high-end gaming console, alongside the Xbox Series X/S. It has a terrific library of exclusive games at this point and it can run pretty much any PS4 game too. Along with strong performance and excellent visuals, the PS5 has one killer feature that helps it stand out from the Xbox Series X/S: the DualSense controller. The haptic feedback and adaptive triggers (i.e. varying tension levels in the L2 and R2 buttons as you pull the string on a virtual bow or drag an object) help create a feeling of immersion Xbox consoles can't quite match yet.

Microsoft appears to have blocked several prompts in its Copilot tool that led the generative AI tool to spit out violent, sexual and other illicit images. The changes seem to have been implemented just after an engineer at the company wrote to the Federal Trade Commission to lay out severe concerns he had with Microsoft's GAI tech.

When entering terms such as “pro choice,” “four twenty” (a weed reference) or “pro life,” Copilot now displays a message saying those prompts are blocked. It warns that repeated policy violations could lead to a user being suspended, according to CNBC.

Users were also reportedly able to enter prompts related to children playing with assault rifles until earlier this week. Those who try to input such a prompt now may be told that doing so violates Copilot’s ethical principles as well as Microsoft’s policies. “Please do not ask me to do anything that may harm or offend others,” Copilot reportedly says in response. However, CNBC found that it was still possible to generate violent imagery through prompts such as “car accident,” while users can still convince the AI to create images of Disney characters and other copyrighted works.

Microsoft engineer Shane Jones has been sounding the alarm for months about the kinds of images Microsoft's OpenAI-powered systems were generating. He had been testing Copilot Designer since December and determined that it output images that violated Microsoft's responsible AI principles even while using relatively benign prompts. For instance, he found that the prompt “pro-choice" led to the AI creating images of things like demons eating infants and Darth Vader holding a drill to a baby's head. He wrote to the FTC and Microsoft's board of directors about his concerns this week.

“We are continuously monitoring, making adjustments and putting additional controls in place to further strengthen our safety filters and mitigate misuse of the system," Microsoft told CNBC regarding the Copilot prompt bans.

Apple has reversed course on its decision to ban Epic Games' developer account after it emerged European Union officials were looking into the issue. The about turn means that Epic will be able to bring its own app store to iPhones and iPads in the EU. The publisher will also be able to more easily bring Fortnite back to those devices in the bloc, nearly four years after Apple kicked the game out of the App Store over an in-app purchases battle (a decision that spurred a drawn-out legal tussle between the two sides).

"Following conversations with Epic, they have committed to follow the rules, including our DMA [Digital Markets Act] policies," an Apple spokesperson told Engadget. "As a result, Epic Sweden AB has been permitted to re-sign the developer agreement and accepted into the Apple Developer Program."

"Apple has told us and committed to the European Commission that they will reinstate our developer account," Epic wrote in an updated blog post. "This sends a strong signal to developers that the European Commission will act swiftly to enforce the Digital Markets Act and hold gatekeepers accountable. We are moving forward as planned to launch the Epic Games Store and bring Fortnite back to iOS in Europe. Onward!"

Apple killed Epic's developer account earlier this week, claiming that Epic was unlikely to abide by the related contractual agreements. Its lawyers described Epic as "verifiably untrustworthy."

The sudden about face surely has nothing to do with reports that EU regulators planned to question Apple over the ban. Epic claimed the decision was a "serious violation of the DMA." Under that law, which just came into effect, Apple is required to allow third-party app stores on iOS in the EU. However, Apple is still forcing companies that want to have their own app marketplace on iPhone to abide by its rules.

Also this week, the EU fined Apple almost $2 billion for suppressing third-party music streaming apps on the App Store by preventing them from telling users that they could subscribe to their services elsewhere for a lower cost than if they signed up through iOS. This was the first fine the EU has given Apple, and the bloc's third-largest financial penalty ever. Apple is appealing the fine. 

Given the even heftier penalties that companies face for failing to comply with the DMA — up to 10 percent of their annual revenue — and the EU showing it's ready to wield its power when necessary, it's not too surprising that Apple backed down from its latest scrap with Epic. Indeed, Epic CEO Tim Sweeney said Apple backtracked after "a swift inquiry by the European Commission."

As is always the case between seasons, Epic Games took Fortnite offline early on Friday to perform some maintenance and get the game ready for all the new stuff fans are about to enjoy. While the downtime typically lasts a few hours, Epic has encountered a problem that's forcing it to delay the start of Chapter 5 Season 2.

"Hey everyone, we encountered an unexpected issue during our maintenance and we need to extend downtime at least 8 additional hours," a post on the Fortnite Status X account reads. "We apologize for making everyone wait longer than usual to drop into Chapter 5 Season 2 of Battle Royale. The team is working through this as quickly as possible, and we’ll provide another update when we have more info." The tweet was posted at 9:14AM ET, meaning Fortnite will likely remain down until at least 5PM. 

The delay is a bit of a pity as the new season looks pretty compelling. It's called Myths and Mortals and it's focused on Greek gods. Along with earning skins for the likes of Aphrodite, Medusa and Poseidon through the battle pass, you can wield mythical powers such as Zeus' lightning bolts and the Wings of Icarus. Epic has added some intriguing new areas to the island as well, including Mount Olympus and Hades' Underworld. A spooky-looking version of the River Styx, which is guarded by Cerberus, leads up to the latter. 

Now might be a good time to snap up a PlayStation 5 if you've been on the fence and are particularly interested in playing Marvel's Spider-Man 2. A bundle of the console and the game is currently $50 off. The savings apply to both versions of the console, so you can snag an all-digital version of the PS5 with Spider-Man 2 for $400. If you'd prefer to have a standard edition of the console with a disc drive to perhaps watch Blu-ray movies on, the bundle will run you $450.

If you're a newcomer to the PlayStation ecosystem, Spider-Man 2 is an excellent way to get your collection of PS5 games started. It's one of our favorite games of last year and we felt it was both bigger and better than the first game in the series. If you'd prefer to play Marvel's Spider-Man and Marvel's Spider-Man: Miles Morales before diving into the latest entry (both are great games too), you can check them out through the PlayStation Plus subscription service on the Extra and Premium tiers.
