When X's engineering team published the code that powers the platform's "for you" algorithm last month, Elon Musk said the move was a victory for transparency. "We know the algorithm is dumb and needs massive improvements, but at least you can see us struggle to make it better in real-time and with transparency," Musk wrote. "No other social media companies do this."
While it's true that X is the only major social network to make elements of its recommendation algorithm open source, researchers say that what the company has published doesn't offer the kind of transparency that would actually be useful for anyone trying to understand how X works in 2026.
The code, much like an earlier version published in 2023, is a "redacted" version of X's algorithm, according to John Thickstun, an assistant professor of computer science at Cornell University. "What troubles me about these releases is that they give you a pretense that they're being transparent for releasing code and the sense that someone might be able to use this release to do some kind of auditing work or oversight work," Thickstun told Engadget. "And the fact is that that's not really possible at all."
Predictably, as soon as the code was released, users on X began posting lengthy threads about what it means for creators hoping to boost their visibility on the platform. For example, one post that was viewed more than 350,000 times advises users that X "will reward people who conversate" and "raise the vibrations of X." Another post with more than 20,000 views claims that posting video is the answer. Another post says that users should stick to their "niche" because "topic switching hurts your reach." But Thickstun cautioned against reading too much into supposed strategies for going viral. "They can't possibly draw those conclusions from what was released," he says.
While there are some small details that shed light on how X recommends posts — for example, it filters out content that's more than a day old — Thickstun says that much of it is "not actionable" for content creators.
Structurally, one of the biggest differences between the current algorithm and the version released in 2023 is that the new system relies on a Grok-like large language model to rank posts. "In the previous version, this was hard coded: you took how many times something was liked, how many times something was shared, how many times something was replied … and then based on that you calculate a score, and then you rank the post based on the score," explains Ruggero Lazzaroni, a pHD researcher at the University of Graz. "Now the score is derived not by the real amounts of likes and shares, but by how likely Grok thinks that you would like and share a post."
That also makes the algorithm even more opaque than it was before, says Thickstun. "So much more of the decisionmaking … is happening within black box neural networks that they're training on their data," he says. "More and more of the decisionmaking power of these algorithms is shifting not just out of public view, but actually really out of view or understanding of even the internal engineers that are working on these systems, because they're being shifted into these neural networks."
The release has even less detail about some aspects of the algorithm that were made public in 2023. At the time, the company included information about how it weighted various interactions to determine which posts should rank higher. For example, a reply was "worth" 27 retweets and a reply that generated a response from the original author was worth 75 retweets. But X has now redacted information about how it's weighing these factors, saying that this information was excluded "for security reasons."
The code also doesn't include any information about the data the algorithm was trained on, which could help researchers and others understand it or conduct audits. "One of the things I would really want to see is, what is the training data that they're using for this model," says Mohsen Foroughifar, an assistant professor of business technologies at Carnegie Mellon University. "if the data that is used for training this model is inherently biased, then the model might actually end up still being biased, regardless of what kind of things that you consider within the model."
Being able to conduct research on the X recommendation algorithm would be extremely valuable, says Lazzaroni, who is working on an EU-funded project exploring alternative recommendation algorithms for social media platforms. Much of Lazzaroni's work involves simulating real-world social media platforms to test different approaches. But he says the code released by X doesn't have enough information to actually reproduce its recommendation algorithm.
"We have the code to run the algorithm, but we don't have the model that you need to run the algorithm," he says.
If researchers were able to study the X algorithm, it could yield insights that could impact more than just social media platforms. Many of the same questions and concerns that have been raised about how social media algorithms behave are likely to re-emerge in the context of AI chatbots."A lot of these challenges that we're seeing on social media platforms and the recommendation [systems] appear in a very similar way with these generative systems as well," Thickstun said. "So you can kind of extrapolate forward the kinds of challenges that we've seen with social media platforms to the kind of challenges that we'll see with interaction with GenAI platforms."
Lazzaroni, who spends a lot of time simulating some of the most toxic behavior on social media, is even more blunt. "AI companies, to maximize profit, optimize the large language models for user engagement and not for telling the truth or caring about the mental health of the users. And this is the same exact problem: they make more profit, but the users get a worse society, or they get worse mental health out of it."

The Pixel 10a is official, though details are limited. On Wednesday, Google posted a teaser video showing the mid-range phone dancing around colorful backgrounds. You can pre-order the Pixel 10a on February 18.
Google hasn't yet revealed the phone's specs. In the short video, we can see a blue model that's virtually indistinguishable on the outside from the Pixel 9a. And alleged leaks point to a phone with few changes on the inside. That (unconfirmed) list includes a 6.285-inch display, dual rear cameras (48MP wide and 13MP ultra-wide) and a 5,100mAh battery.
The teaser's tagline appears to be an attempt to assure Pixel fans that there will, in fact, be meaningful upgrades. "A phone with more in store, in store soon," it reads. Hopefully, its pricing and specs will be "in store" for us soon as well.
In the meantime, you can visit the Google Pixel website to register for more info.

If you're looking to up your privacy game on the internet in the new year, you can do so for a little less than usual thanks to ExpressVPN's latest deal. Its two-year plans are up to 81 percent off right now: the Advanced tier is on sale for $88 for two years, plus four additional free months. The Basic plan is where you'll see the biggest discount: it's $68 for two years, plus the same four additional free months.
We’ve consistently liked ExpressVPN because it’s fast, easy to use and widely available across a large global server network. In fact, it's our current pick for best premium VPN. One of the biggest drawbacks has always been its high cost, and this deal temporarily solves that issue.
In our review we were able to get fast download and upload speeds, losing only 7 percent in the former and 2 percent in the latter worldwide. We found that it could unblock Netflix anywhere, and its mobile and desktop apps were simple to operate. We gave ExpressVPN an overall score of 85 out of 100.
The virtual private network service now has three tiers. Basic is cheaper with fewer features, while Pro costs more and adds extra perks like support for 14 simultaneous devices and a password manager. Advanced sits in the middle and includes the password manager but only supports 12 devices.

Anthropic has announced that its chatbot Claude will remain ad-free. This is in direct contrast to rival company OpenAI, which recently brought ads to ChatGPT for many users.
The company says that "including ads in conversations with Claude would be incompatible" with the chatbot becoming a "genuinely helpful assistant for work and for deep thinking." The reasoning here is rather simple. People tend to share personal details with chatbots, for better or for worse, and getting ads based on that stuff would be creepy. Imagine asking for mental health advice and getting an ad for St. John's wort or something.
Anthropic notes that other conversations "involve complex software engineering tasks, deep work or thinking through difficult problems. The appearance of ads in these contexts would feel incongruous—and, in many cases, inappropriate."
The company said that integrating advertising would "work against" the Claude Constitution, which counts "being generally helpful" as a core principle. "Introducing advertising incentives at this stage would add another level of complexity. Our understanding of how models translate the goals we set them into specific behaviors is still developing; an ad-based system could therefore have unpredictable results," it writes in a blog post.
There are some real world concerns here. AI companies gobble up all money in sight and the returns haven't exactly been stellar. Ads are an easy way to recoup some of that investment, which is likely why OpenAI went that route. Engadget reached out to Anthropic to inquire about any kind of forthcoming financial hurdles that could force it to change course. A representative pointed to today's blog post and said it's "all the information we have to share at this time."
We do know that Anthropic remains committed to commerce-based agentic AI. It said it will "continue to build features that enable our users to find, compare or buy products, connect with businesses and more."

Samsung’s 2025 was filled with new foldables, an ultra-thin new form factor and the launch of Google's XR platform. After making some announcements at CES 2026, the company is expected to host its first Galaxy Unpacked of the year in February to introduce the Galaxy S26 lineup. Official invites have yet to be shared, but the date is widely expected to be near the end of the month, probably on February 25 But as usual, we know a lot about what’s expected when Samsung does hold its next event.
Whenever it does happen, Engadget will be covering Galaxy Unpacked live, and we'll most likely have hands-on coverage of Samsung's new smartphones soon after they're announced. While we wait for an official invite, here's everything we expect Samsung will introduce at the first Galaxy Unpacked event of 2026.
But first, when is Unpacked going to happen? A recent image shared by leakster Evan Blass indicated Unpacked should be taking place on “February 25 2026.” Blass has a long history of credible leaks, which means this date is all but confirmed, and the main questions remaining would be — what time and in what timezone? We’re still waiting on Samsung for the official details, which should include answers to those questions.
Samsung's restrained approach to updating its phones will likely continue with the Galaxy S26. Based on leaked images of the new lineup, the company is not expected to radically reinvent the look of the Galaxy S26, Galaxy S26+ or Galaxy S26 Ultra, and instead will stick with a similar design to what it used on the Galaxy S25. The phones will have a flat front screen and frame, with rounded corners and cameras housed in a vertical pill-shaped plateau on the back. Unlike Apple's move from the iPhone 16 Pro to the iPhone 17 Pro, the biggest difference here will likely be internal components like the screens, chips and camera sensors Samsung uses.
Qualcomm's new Snapdragon 8 Elite Gen 5 chip is expected to be in all Samsung Galaxy S26 phones, though Korean news site Yonhap News reports Samsung's relatively new Exynos 2600 chip could be used in some phones in the lineup depending on the region, a strategy Samsung has deployed in the past. Either way the new phones should be more performant than the previous generation, and in the case of the models with the Snapdragon 8 Elite Gen 5, particularly good at on-device AI processing.

One notable difference between the Galaxy S26 and the Galaxy S25 could be the phone's screen. The new phone will reportedly feature a 6.3-inch FHD+ display according to specs shared by leaker Ice Universe, which makes it ever so slightly larger than the 6.2-inch display used on the Galaxy S25. The S26 will also allegedly come with 12GB of RAM, either 256GB or 512GB of storage and a slightly larger 4,300mAh battery. Samsung isn't changing the cameras on the entry-level phone, though: leaks suggest it'll feature the same 50-megapixel main camera, 12-megapixel ultrawide, 10-megapixel 3x telephoto and 12-megapixel selfie camera as the previous generation. Changes appear to be even more minor on the Galaxy S26+. Other than the new Snapdragon chip, the phone will reportedly feature the same 6.7-inch FHD+ screen, 4,900mAh battery, 12GB of RAM and the same camera array used on the base Galaxy S26.
The difference between the Galaxy S26 Ultra and Galaxy S25 Ultra is reportedly a bit clearer. According to Android Headlines, the new phone's cameras will be slightly more raised, and stand out thanks to a new metallic finish. Samsung may also switch back to using an aluminum frame on the Galaxy S26 Ultra, after using titanium frames on both the Galaxy S24 and S25 Ultras. Most importantly, to make the phone actually support Qi2 rather than only technically work with the standard when a case is attached, rumors suggest Samsung will remove the S Pen digitizer layer in the phone and adopt a new method for accepting stylus input. It's not clear what that new method will actually be, but it could let the Galaxy S26 Ultra more easily work with Qi2 accessories without losing its stylus.
Android Headlines also recently shared what appear to be full image renders of the S26 series, and they generally line up with what has already been rumored, leaked and reported so far. If these pictures are accurate, they give us a clearer look at the camera bump and two color variants of the S26 Ultra.
Fans of magnets may continue to be disappointed by Samsung if the latest rumors are accurate. Despite the launch of the Qi 2 wireless charging standard adding support for convenient magnetic alignment years ago, Samsung has yet to bring that feature to its phones. Though the S-series have the higher speed charging rates that the spec enables, Nieuwemobiel.nl is reporting that, due to images it received of cases with magnetic rings, the S26 series likely won’t have built-in magnets. Samsung has made these cases to add the magnetic capability to its S-series in the past, and the existence of the images of these accessories lends weight to the idea that the company will continue this approach.
Samsung released the Galaxy Buds 3 and 3 Pro in 2024, with a major redesign that brought them much more in line with Apple's AirPods. The Galaxy Buds 4 and Buds 4 Pro Samsung is rumored to be announcing soon won't necessarily change that, though they will feature a more compact case and less angular stems, according to leaked images from the Samsung Tips app.
Support for head gestures to accept and decline calls, a feature Apple includes on the AirPods Pro 3 and AirPods 4, is also rumored to work on both versions of the new Galaxy Buds. SamMobile reports the Galaxy Buds 4 and 4 Pro may also ship with a new Ultra Wideband chip that will make them easier to find with Google's Find Hub network.
Samsung announced the Galaxy Z TriFold in late 2025 without firm details of when the new smartphone-that-folds-into-a-tablet would be available in North America. That info came on January 27, when the company announced the TriFold would be available in the US on January 30, for a whopping $2,900. Considering we’ve already seen the device in person at CES 2026 and people are most likely to have had a chance to look at, if not buy the foldable for themselves by the time Unpacked rolls around, we don’t expect Samsung to spend too much time dwelling on it, if at all.
When the Galaxy S25 Edge was announced in 2025, it seemed possible that Samsung could replace its "Plus" smartphone with a unique form factor, just like Apple has opted to do with the iPhone Air. There have been conflicting reports on the matter, but it seems like Samsung will not be doing that with the Galaxy S26 Edge.
Instead, the smartphone will reportedly remain another option, much like foldables are for customers not swayed by Samsung's traditional smartphones. The Galaxy S26 Edge is rumored to feature a slightly different design than last year's model, according to Android Headlines, with a large rectangular camera plateau that's reminiscent of Google's Pixel phones, and the raised oval Apple used on the iPhone Air. Beyond that, the phone is also expected to be ever so slightly thinner at 5.5mm than the 5.8mm Galaxy S25 Edge.
Samsung already acts as a first place Google can show off new AI features for Android, but the company is reportedly exploring other AI partnerships, too. In June 2025, Bloomberg reported that Samsung was nearing a deal with Perplexity to integrate its AI-powered search engine across OneUI and its homegrown mobile browser. Perplexity already has a deal with Motorola on its Razr phones, so the only thing that would make a deal with Samsung unusual is the close relationship the company already has with Google.
The company also accidentally announced a new version of its Bixby AI assistant, which will likely also be integrated with Perplexity and could serve as an alternative to Google Gemini. Both a new Bixby and a deeper integration with Perplexity seem like natural new software features to show off at Galaxy Unpacked.
