Anthropic corners Gemini 3 Pro and GPT-5.2 more than ever

by

Think for a moment about the artificial intelligence models you have used in recent days. It may have been through ChatGPT, Gemini either Claudeor perhaps through tools like Codex, Claude Code or AI Cursor. In practice, the choice is usually simple: we end up using what best fits what we need at any given moment, almost without stopping to think about the technology behind it. However, that balance changes frequently. Each new model that appears promises improvements, new capabilities or different ways of working, and with it a fairly direct question returns: if it is worth trying, if it can really offer us something better or if what we already use is still enough. Claude Sonnet 4.6 just came to the foreand this is how it is positioned against the competition. Claude Sonnet’s starting point 4.6. Here we find what Anthropic describes as a transversal improvement in capabilities, which includes advances in coding, computer use, long-context reasoning, agent planning, and tasks typical of intellectual and creative work. Added to this set is a context window of up to one million tokens in beta, designed to process entire code bases, extensive contracts or large collections of information without fragmentation. Three levels, the same map. To understand where Sonnet 4.6 fits in, it’s worth looking at how Anthropic tends to organize its family of models into different levels with different objectives. Haiku prioritizes speed and efficiency, Opus is reserved for tasks that require the deepest reasoning, and Sonnet occupies the middle ground, designed as a balance between capacity and operating cost. Within this framework, the company maintains that the new Sonnet comes close in some real jobs to the performance previously associated with the Opus, an ambitious claim. When AI starts using the computer. One of the improvements that Anthropic highlights most strongly in Sonnet 4.6 is its progress in what it calls computer usethat is, the ability of the model to interact with software in a way similar to a person, without depending on APIs designed specifically for automation. This progress is supported by references such as OSWorld-Verified, a testing environment with real applications where the Sonnet family has been improving steadily over several months. The company also recognizes limits and risks that we have talked about before, such as attempts at manipulation through prompt injection. Searching for the ‘best’ model. At this point, the relevant question stops being how much Sonnet 4.6 has improved in absolute terms and begins to focus on how it is compared to the other large models that today compete for the same space of use. The comparison is not simple nor does it allow for a single winner, because each system excels in different areas and responds to different technical priorities. That is why it is advisable to read the benchmarks with a practical perspective, identifying in which specific tasks the real differences appear. Where each model stands out. The direct comparison with GPT-5.2 draws a distribution of strengths rather than a clear victory. According to the table published by Anthropic, Sonnet 4.6 stands out especially widely in the autonomous use of the computer measured in OSWorld-Verified, in addition to showing an advantage in office tasks (GDPval-AA Elo) and in some analysis or problem solving scenarios (Finance Agent v1.1, ARC-AGI-2). GPT-5.2, for its part, maintains better results in graduate-level reasoning (GPQA Diamond), visual comprehension (MMMU-Pro) and terminal programming (Terminal-Bench 2.0), with nuances such as results marked as Pro in some tests (BrowseComp, HLE) or self-reported grades in Terminal-Bench 2.0. The comparison with Gemini 3 Pro introduces a different nuance, because here the advantages are concentrated above all in the field of reasoning and general knowledge. The Google model obtains better results in graduate-level reasoning tests (GPQA Diamond) and in wide-ranging multilingual questionnaires (MMMLU), in addition to being ahead in visual reasoning without tools (MMMU-Pro). Sonnet 4.6, on the other hand, retains a certain advantage when external tools or scenarios closer to the applied work come into play. The absence of some comparable data in the table itself forces, in any case, to interpret this duel with caution. Where Sonnet 4.6 can be used. The new model is available in all Claude plans, including the free level, where it also becomes the default option within claude.ai and Claude Cowork. It can also be used through Claude Code, the API and the main cloud platforms, maintaining the same price as the Sonnet 4.5 version. After going through capabilities, limits and comparisons, the real decision returns to the user’s daily life. Sonnet 4.6 aims to be especially useful in productive tasks, direct interaction with software and long workflows, while GPT-5.2 and Gemini 3 Pro maintain advantages in academic reasoning, visual comprehension or general knowledge depending on the test considered. No one dominates all fronts, and that fragmentation defines the current moment of artificial intelligence. Images | Anthropic In Xataka | In 2025, AI seemed to have hit a wall of progress.

After “skincare”, the new cosmetic fever focuses on one of the most hidden corners of the body: the scalp

by

For years the message was simple: maintain good hydration and, please, do not go to sleep without removing your makeup. Then we immersed ourselves and fell in love with a new trend: the skincare and his feared ten steps exported from South Korea. Now, in 2026, when it seems that we already have the keys to a good routine integrated, and our pulse does not tremble when deciding whether the serum goes before or after the moisturizing cream, a new task arises. In the midst of a fever to optimize health, the focus moves a few centimeters higher: the scalp. The ten-step routine falls short It is increasingly common to find yourself in cities or, failing that, on TikTok, with centers of hair spa Japanese inspired. Cranial massage, activation of energy points, water jets and hair diagnosisall seasoned with an environment that offers an experience of absolute relaxation. With a proposal this striking, it is not surprising that these treatments have become the new object of desire. beauty. But, as happens with almost everything that promises well-being and succeeds on social networks, an inevitable question arises: are we facing a new gesture to care for our well-being based on science or a new fashion without much sense? This “instagrammable” fusion of hair care with moments of relaxation was born in Asia but the franchise Japanese Head Spathanks to viral videos, has awakened the desire of thousands of users and has managed to adapt the treatment to the European public; especially when emphasizing the relaxation and well-being part. (Unsplash) Aída García, the promoter of the business, discovered the technique at a fair in Miami, but also through TikTok videos, mostly from accounts in Saudi Arabia, where many users wondered when something like this would arrive in Spain. It was then that it detected this gap in the market and decided to take the step, currently having more than 25 centers spread throughout the national territory. “It seems easy, but behind it there are years of experience, an incredible team and a very strong focus on marketing; for example, TikTok has been key because every time we upload a video, our agenda fills up” Aida Garcia, promoter of Japanese Head Spa It is clear that the virality and striking nature of the treatment is what attracts so many users, helping the proliferation of these establishments. Not in vain, these types of centers top the list of trends in spas and wellness, with a 233% increase in searches in 2025 compared to the previous year according to the report SpaSeekers. But there is undoubtedly another compelling reason for this growth. And it is that in a day to day where they prevail the rush and frenetic paceany help to lower the revs is welcome: “They come here from girls who give it to their mothers because they have seen it on TikTok, women aged 30-40 who come accompanied by their partners or grandmothers with their granddaughters. Nowadays, when we have cortisol through the roof and we are going a mile an hour, everyone needs to stop, that is why a hair spa treatment is super giftable,” explains García. This trend around the globe has meant that the endless skincare routines with ingredients such as hyaluronic acid or niacinamide are also transferred to scalp care. As an example, the term “scalp serum” recorded, for much of 2025, a monthly average of more than 910,000 results on social networks such as Instagram or TikTok; assuming an increase of 77% compared to the previous year. Furthermore, if we focus on the global market, sales of products and treatments dedicated to the scalp grew by 4.2% in 2024 and the trend continued to increase in 2025, the year in which articles intended for this area of ​​the body reached 9.6 billion of dollars. (Unsplash) South Korea is not far behind in this trend, honoring its deep cult of beauty. What’s more, the debate about hair loss has transcended the merely aesthetic and has become a public policy issue thanks to the South Korean president and his proposal to cover baldness treatments by the national health insurance. According to Lee, for many young people the problem has stopped being aesthetic and has become “a survival question“On the other hand, when it comes to the viral, there are many spa centers in the country in which famous and influencers enjoy those 15 or 18 steps which includes the Head Spa treatment promising to cleanse, revitalize and balance the scalp. Indeed, the entire experience of this ritual, if we focus on its relaxation aspect, is something positive and can benefit us. However, it is when it comes to hair diagnosis and the avalanche of products with active ingredients where we have to put the brakes on and be more cautious. There are no shortcuts to healthy hair The truth is that although these spas claim that in general they are treatments suitable for all types of hair and scalp, they always urge people with specific conditions such as psoriasis to consult with a dermatologist first. And that’s what we have done, although to satisfy all our doubts: “People have a profound lack of knowledge about health in general, and about the aesthetics and health of the skin and hair in particular, it is something that I see a lot in consultation, that false sense of information. Sometimes they make cherry-picking and they do not know how to relate the concepts, which in the end is the most important thing,” says Dr. Silvia Berjón, a specialist in trichology. The Glowmour Clinic doctor agrees with the sensory and well-being benefits that these treatments provide. Emphasizing “the value of human contact and the release of oxytocin that can cause this relaxation process.” Furthermore, from its focus on longevity medicine emphasizes that not only healthy habits influence a longer and fuller life but, as supported by science, “also activities that nourish emotionally and help reduce stress”, such as these types of rituals.

If when you think of a farm you visualize a red building with white corners, it’s the Swedes’ fault.

5040-Y80R. That is the approximate designation according to the Natural Color System chart for color ‘red falu‘. It is a registered trademark and It goes beyond being a simple color: implies that a very specific pigment comes into play in its production that gives it that reddish tone and has transcended to the point of being part of the identity of an entire country thanks to its properties. That country is Sweden, and it all started as a waste product from a copper mine. By-product. Dalarna is a region located in the heart of Sweden, and it is home to the Falun Great Copper Mountain. The Vikings They were already exploiting this mine in 850, but the history of color dates back to the 16th century. It was then that they discovered that one of the mining byproducts could be turned into a useful pigment. Leaf From the production of copper they obtained what they called Falu rödfärgor “red mulch,” and was basically a unique mixture of over 20 different minerals. The reddish color was thanks to iron oxide, silica, zinc and copper itself. They started to mix it up with water, but also with other elements such as oils, tar or rye flour, and they discovered that they could obtain a paint with very interesting properties. better than paint. This red mulch mixed with the appropriate ingredients not only gave color to the wood, primary raw material in Sweden for both ships and infrastructure, but also acted especially well as a material protector. It was like an insulating layer, a shield that protected against the elementsprolonging its useful life, making repairs less frequent and, in addition, it was cheaper than importing wood treatments from other countries. The industry soon exploded. HE esteem that, by mid-1760, production was about 25 tons, but by 1930, that annual production exceeded 2,000 tons. Status. Now, it wasn’t cheap. Everyone wanted to paint their house that copper red color, but it turns out that it was a luxury reserved for the highest classes. When the pigment was discovered, and perhaps motivated only by its color, King John III ordered paint the ceilings of his palace with ‘falu red’, imitating the copper of the ceilings of other European palaces. Since then, those with the most power who could get hold of the pigment began to paint their houses. However, as production began to scale and gain traction, the product became cheaper and more people were able to access it, painting, if not all of their houses, the façade that faced the roads (which was what everyone passing by could see). Swedish edges of the 19th century contributed to popularize the image of the red houses of Sweden, immortalizing the idea of ​​rural life in red houses with white corners. One of Carl Larsson’s works The color of a nation. The color 5040-Y80R became the symbol of Sweden to the point that migrants who sought better luck in North America after the dissolution of the norwegian swedish union In 1905 they began to build their farms using this color. The image that many of us have of the red farm was created there. And it became so important to Swedish popular culture that there is a saying that symbolizes that simple life and harmonious in contact with the earth: den röda stugan och potatislandet (the red house and the potato garden). Today, the ‘Falu rödfärg’ is not as vital as it was years ago if we talk about production. The same has descended a lot because there is greater competition and synthetic products for paint the facadesbut it is still an example of “banal nationalism”, a symbol that exists without the need for flags and anthems, since its mere presence evokes belonging.

Ode to rounded corners, the visual element that has proven Steve Jobs right once again

by

Let’s pay a small tribute to a visual element that we almost never pay attention to, but that is already an integral part of our lives. Let’s talk about rounded corners. They are everywhere and have taken over technology. We love them. We are full of devices and interfaces dominated by rectangles and squares with rounded corners. They are more elegant, softer to look at, much less aggressive and strident. But there is a true psychology behind that way of designing objects and interfaces. For example: since we were little we always knew that sharp corners were dangerous – today corner protectors for children are a big deal. These elements facilitate visual perception, and their introduction into the technological world deserves to be remembered. Steve Jobs was right (again) Andy Hertzfeld was one of the team members who developed the Apple Macintosh. In May 1981 he shared a curious story, now recovered by the Computer History Museum. Lisa OS 1.0. Look at the edges of the calculator app. They are rounded! The protagonist of that story is Bill Atkinson, legendary Apple engineer and Hertzfeld’s partner on that project. At that time Atkinson was working on the development of his QuickDraw application – then called LisaGraf – and although he usually worked from home, if he made any significant progress he would quickly go to the office to show off the improvement. That’s what happened that spring. Atkinson approached Apple’s offices in mythical “Texaco Towers” Cupertino campus and showed how he had added code to be able to draw circles and ovals very easily. Programming that was much more complicated than it seems because square roots were usually involved to achieve it and the Motorola 68000 of the Lisa and the Macintosh did not support floating point operations. Atkinson managed to solve it with calculations that only used addition and subtraction—he was probably inspired by the Bresenham algorithm—and began to fill the screen with circles and ovals while his companions probably smiled in astonishment and satisfaction. But there was someone who was neither too amazed nor too pleased. That someone was Steve Jobs. Upon seeing the demonstration, Jobs said —Okay, circles and ovals are fine, but How about drawing rectangles with rounded corners? Can we do that too? —No, there is no way to do it. “It would actually be really difficult to do, and I don’t really think we need it,” Atkinson replied, probably annoyed that Jobs hadn’t been too impressed with his method for creating circles and ovals. —Rectangles with corners are everywhere! Look around this room! Hello, Mac OS X with rounded corners (2001). Sure enough, the room had objects like whiteboards and tables with rounded corners, and Jobs insisted that they were everywhere and that he only had to look out the window to notice. He ended up convincing Atkinson to take him around the block and point out all the rectangles with rounded corners they saw. After seeing a no parking sign that was rectangular with rounded edges, he said: —Okay, I give up. I’ll see if it’s as difficult as I thought. And he went home to work on the problem. The next afternoon he returned to the office with a huge smile: his new demo I didn’t just draw rectangles with rounded cornersbut it did it almost as fast as it did drawing rectangles with corners. He added that code and called that primitive “RoundRects”. In our pockets we usually carry a device that makes good use of these rectangles with rounded corners. The iPhone, of course, does it. That design element soon became an integral and indispensable part of the Macintosh operating system interface. And it also ended up being part of the hardware (hello, mobile phones with rounded corners) and software design at both Apple and many other technology companies. Source: Freepik. The Cupertino firm also fully integrated it into its iPhones starting in 2013, when iOS 7 and its “squircle” arrivedan even more subtle type of rectangle with rounded corners that he ended up using, for example, in his icons. It was one more example of the particular relevance of a design element that has ended up completely taking over our screens and the technological world. Long live the rounded corners.
