OpenAI wanted to simplify its AI products. You’ve ended up with a salad of ChatGPT, Atlas and Codex

If you have become accustomed to opening the application ChatGPT and always work from the same place, when you update you may find yourself with a quite different experience. OpenAI is reorganizing its products and, with them, the routines of those who had already turned their solutions into tools for daily use. The move promises to concentrate functions, but it also forces us to understand again which application should be opened, which environment corresponds to each task, and which parts of the previous flow continue to work the same. Three main pieces. The desktop application that we knew is now called ChatGPT Classic, while a new ChatGPT application brings together Chat, Work and Codex in the same environment. At the same time, Atlas enters its countdown: the browser will remain available for a few weeks, but OpenAI has set its withdrawal for August 9, 2026. The company thus concentrates more capabilities under a single brand, although during the transition names, applications and functions that are not obvious at first glance will coexist. They are not three versions of the same ChatGPT. Chat continues to be the space to talk, write, search for information, analyze files or resolve specific queries. Work is designed for longer, multi-stage tasks, such as researching a topic, cross-referencing documents, and preparing reports or presentations. Codex keeps the focus on software development and can work with code, repositories, terminals and other technical tools. All three share an application, but each one responds to a different way of working. The new desktop experience. The changes land on both macOS and Windows. Chat access appears in the left panel next to Work and Codex. When selected, the conversation opens within the general environment, although it can be separated into another window. OpenAI thus retains the most recognizable feature of ChatGPT, but makes it a part of a broader product, with a different organization for those who used the previous application. Atlas, in retreat. OpenAI is moving some of its capabilities to the new app’s built-in browser and to a extension for chrome. The architecture also includes a remote browser from which agents can complete tasks. Anyone who used Atlas as their regular browser will have to prepare for the move: the bookmarks they want to keep can be exported to Chrome, while cookies and passwords can be moved to the new application. Open tabs and browsing history are not transferred automatically. There are alternatives outside. Google is taking Gemini to Chrome itself to understand the open page, summarize content, compare information between multiple tabs, and, in supported accounts, complete multi-step actions. The deployment continues to be limited by region and Spain is not currently among the supported territories. Comet by Perplexitymaintains the browser-agnostic formula and is available on Mac, Windows, Android, iPhone and iPad. Perplexity Pro users can also choose between models from companies such as OpenAI, Anthropic and Google. The idea behind the changes. OpenAI wants ChatGPT to stop being just a chatbot and become the gateway to practically its entire ecosystem. Instead of maintaining separate apps for chatting, scheduling, or browsing, concentrate those functions under one brand. The commitment is reminiscent of the evolution of other large technological platforms, which over time have absorbed previously separate tools to reduce fragmentation and turn a single application into the center of the experience. Background. OpenAI wanted to reduce the complexity of the selector with the arrival of GPT-5but encountered users who did not see the models as interchangeable parts. Some depended on GPT-4o for specific jobs; others preferred his creative abilities and his way of conversing. The company backtracked and offered it again to paying users, before permanently removing it from ChatGPT on February 13, 2026. Perhaps in a few months this transition will be easier than it seems today. But the change brings to mind a well-known idea in software design: We don’t just learn to use a tool, we also build habits around it. When these habits are changed suddenly, the adaptation period becomes as much a part of the experience as the new functions. OpenAI’s challenge will be to make the integration easier for the user than the collection of products it aims to replace.

the biggest naval battle you’ve ever seen on television

It’s been two years since the second season of ‘The House of the Dragon‘ in HBO Max will end, just before one of the key moments of the series: the Battle of the Gorge. This is how this third year of the series based on the work of George RR Martin begins, and it does so with extraordinary reviews, which equal the good times of ‘Game of Thrones’. Will the rest of the season live up to this vibrant start? The second season not only experienced a drop in audience with respect to the first one that made one think that the goose that laid the dragon’s eggs was beginning to look suffocated. There were also complaints from many viewers, who had the perception that the entire year had been a preparation for a naval battle that was about to begin just as the season ended. There was a reason: the season reduced its number of episodes from 10 to 8, and the showrunner Ryan Condal had no choice but to leave the battle for the season that begins now. The Battle of the Gorge is the largest naval conflict in the entire history of Westeros, and pits the forces of Rhaenyra Targaryen, under the command of The Sea Serpent, against the fleet of the Triarchy, allied with the Greens, to break the blockade on King’s Landing. Condal acknowledged that the Gaznate sequence took four years to materialize, and that Even with HBO Max’s budget, it was not clear if it could be filmed on the scale it required.: with dragons, ships and multiple combat fronts. And of course, in the tradition of the series, we will see an important character die who will mark the rest of the season. The third season incorporates several characters from George RR Martin’s book ‘Fire and Blood’: James Norton as Lord Ormund Hightower, Tommy Flanagan as Lord Roderick “Roddy the Ruin” Dustin, Dan Fogler as Ser Torrhen Manderly and Annie Shapero as Alysanne Blackwood. Although without a doubt the most suggestive character will continue to be Rhaenyra: Condal said of her that when a character is told that the gods have chosen him to rule and he has the power of six dragons behind him, “at some point he begins to believe his own legend.” Interesting territory to explore this third year.

If you’ve ever wondered how much a massive black hole weighs, the answer is that the Sun next to it looks like a marble.

“What am I going to have for breakfast today?” when will this heat pass” and “how much does a black hole“are those three questions that you will surely ask yourself every day when you wake up. For the first two the answer is uncertain, but for the third a group of researchers from Carnegie Science in California has the answer. Because they have just measured, for the first time, the mass of an inactive black hole that dates back to the early universe and they do not give the answer in tons because it is a figure that escapes human understanding. But they do give the mass compared to the Sun and… well, it’s still not something we can assume. The weight of a black hole. The results HE they published this past Thursday in Science magazine and they are clear: a black hole located in the center of the galaxy MRG-M0138 has about 6,000 million times the mass of the Sun. The mass of our star is 2 × 10^30 kg, equivalent to 332,946 times the mass of the Earth. Does this leave you calmer? Surely not because it is like when they tell us that one company buys another for 75 billion dollars: These are such absurd quantities that it is very difficult to get the idea of ​​what it entails, but this thing about weighing bodies around the universe makes sense. Fascinatingly, MRG-M0138 is a massive galaxy whose light has traveled to our sensors from a time when the universe was only about 3 billion years old. This galaxy is no longer forming stars and the central black hole is “quiet.” The scale spacel. To achieve the measurement, the team at the Californian center used the James Webb Space Telescope (JWST) to track the movement of stars around the cosmic giant. It is not the first time that the mass of a black hole has been calculated, but it is the first time that it has been done with one that is so far away (10,000 million light years from Earth, 15 times further than the previous measurement record) and, in addition, it is the first time that an inactive black hole in a galaxy of the early universe. This speaks very well of the benefits of the JWST, which with its sensors allows a very defined image of extremely distant bodies, opening up a huge range when it comes to studying what surrounds us. The problem with sleeping black holes is that they are invisible. It does not emit light, so it cannot be observed directly. So, to “weigh it,” the researchers used a technique that had already been used before: stellar dynamics. Basically, they look at the speed at which stars move near the galactic center and compare that speed to that of more distant stars. In this way, they infer the mass of the black hole. So that. To continue knowing what surrounds us, basically. Because it is not just about measuring the mass of something so distant, but about understanding the formation around it. Thus, this discovery offers new clues to researchers about black holes and galaxies that were born in the early universe. A look at the future by looking at the past. Because, until not long ago, it had been difficult to prove whether there was a close relationship between the central black holes of these very old galaxies. Recent findings suggest that those denser galaxies were sites of rapid black hole growth early in the history of the cosmos. Furthermore, this research will be the basis for future work that will delve into this relationship and, above all, it will also be the basis for analyzing the data collected by the JWST in other similar galaxies. In fact, although the JWST is a good cosmic “magnifying glass”, in Chile the observatory is being expandedThe Bells‘ which is supported by Carnegie Science and will allow studying stellar movements in distant galaxies in much more detail than what JWST offers. In the end, it is about continuing to understand the universe and studies like this allow us to test theoretical methods to understand how massive black holes formed, grew, shaped the evolution of galaxies and, ultimately, became silent giants.

Greece wants to prevent its beaches from being suffocated by mass tourism. So you’ve declared war on sun loungers

Greece faces a dilemma. One well known in other countries that, like Italy, France, Holland, Japan either Spainhave become dream destinations for travelers from all over the world: their tourist attraction threatens to make them die of successsuffocated by overcrowding. To avoid this, the Greek Government has decided to shield around 250 beaches to maintain them as “virgin” sandbanks. In practice, this means that things as basic as renting umbrellas or sun loungers cannot be done there. “Virgin beaches”. If Greece is one of the most visited countries in the world and becomes the summer resort of millions of tourists It is basically because of four things: its Mediterranean climate, its historical heritage, its gastronomy and (above all) its landscapes and beaches. The Government knows this and that is why some time ago it prepared a list of “Virgin Beaches” either “unauthorized”coastal areas in which the authorities apply more restrictive control. Goodbye umbrellas, sun loungers and motorcycles. Among other thingsin these protected spaces it is not permitted to rent umbrellas and sun loungers, set up new bars or install music equipment and speakers. Nor organize events in which they participate more than ten people or use jet skis. In short: they are beaches open to the public and where you can lie down and sunbathe, but unlike the busiest areas you will hardly find commercial services or of course large tourist infrastructures. The idea is to preserve them in their natural state. The key figure: 251. Nothing new so far. What is striking is that the Greek Ministries of Economy and Environment have decided to expand the list of beaches to which this level of protection applies. Specifically, they have added 13 new sandy beaches, according to the local presswith which the ‘armored’ coves and beaches go from 238 to 251. The data is interesting in itself, but above all because the trend that draws: In recent years Athens has been expanding its protected coastal strip. From the 198 beaches in 2024 it went to 238 in 2025 and to 251 that will be monitored this summer. What is the objective? Don’t kill the goose that lays the golden eggs. Greece is full of idyllic beaches, but the mix of overtourism and uncontrolled commercial exploitation, with sandy areas covered by beach bars, umbrellas, sun loungers and rental jet skis, can make it less attractive. The Government also appeals to the need to protect the formations and ecosystems of the Greek coast. “The amendment seeks to effectively protect beaches that have a particular aesthetic, geomorphological or ecological value, as well as preserve the types of habitats and species of flora and fauna found there,” they argue. Earrings from the Natura Network. “Specifically, the coastal zones and beaches located in areas included in the National Catalog of Areas of the European Ecological Network Natura 2000 are expanded, in which use concessions are already prohibited, as well as any other action that could endanger their morphology and integrate with regard to their ecological functions,” duck the Government. To clear up doubts, the Greek authorities have published a list in which you can consult the beaches where businesses dedicated to renting umbrellas, sun loungers or motorcycles have been banished. These include sandy areas of Koufonisia, Chania or Lefkada. Some of the beaches added to the list have been in the center of controversy in recent years precisely because of tourism development plans that included new structures. The other data: 38 million. It is no coincidence that Greece decides to reinforce the care of its beaches right now. With the international tourism boom As a backdrop, in 2025 the country received about 37.98 million of foreign visitors (not including cruises), 5.6% more than the previous year. That rebound came accompanied by something else: an intense flow of billions of euros. Specifically, it is estimated that last year the income generated by the sector skyrocketed by 9.4% to reach 22.6 billion of euros, a figure that increases noticeably if you add the cruise passengers. These are important data due to their weight… and to understand the zeal with which Greece wants to take care of its sandy beaches, preventing part of its coastline from becoming overcrowded. If the tourism sector has learned anything in recent years, it is how easy it is to die of success. Without going any further, there are already travel guides that advise against visiting Mallorca, Barcelona or the Canary Islands because they consider them points hyper-crowded.

You’ve probably never heard of urea. The missiles in Iran are destroying their production, and that will affect your food

At the beginning of the 20th century, the world feared it would run out of food because crops were not growing enough to feed a growing population. The solution came from chemistry: an industrial process capable of manufacturing artificial nutrients for plants and multiplying crops across the planet. Today, this invisible system supports much of what reaches our plates, but it also depends on a global chain. surprisingly fragile. The invisible substance that feeds us. We already said it in the headline, you may not know urea. However, this chemical compound is one of the silent pillars of modern agriculture. It is nitrogen fertilizer most used in the world and indirectly responsible for approximately half of global food production. Its function is simple but crucial: providing nitrogen to crops so they can grow quickly and produce larger harvests. To give us an idea, approximately half of global food production depends on synthetic fertilizers. nitrogen basedand urea is the most widespread of all. Without it, agricultural yields would fall abruptly, which would directly affect products as basic as wheat, corn or rice. The Gulf and fertilizers. It happens that a large part of this global agricultural system depends on a very specific region of the planet: the Persian Gulf. The Middle East is home to some of the largest plants of fertilizer production in the world and is also a key source of raw materials necessary to manufacture them, such as ammonia or sulfur. Furthermore, the Strait of Hormuz has become an essential artery for this trade. between one quarter and a third of the world’s traffic of raw materials for fertilizers passes through this maritime passage, along with approximately 35% of global urea exports and 45% of sulfur trade. A war that hits the food chain. The military escalation in Iran and the attacks around the Strait of Hormuz are starting to interrupt that delicate system. Maritime traffic through the area has been drastically reduced and several ships have been attacked, while industrial facilities in the Gulf have suffered direct damage. In Qatar, one of the largest fertilizer facilities in the world had to stop your production after a drone attack, while Iran has paralyzed its own ammonia production. Every missile in the Iran war is not only destroying its production, it brings us a little closer to a dystopian future scenario. Urea sample in the form of granules The domino effect of urea. When the supply of fertilizers such as urea is interrupted, the impact soon spreads to the food system. If farmers cannot apply enough fertilizer, the ccrops produce less. Some experts estimate that the lack of fertilizers could reduce harvests by up to 50% in the first affected agricultural cycle. This decline would quickly translate in price increases in basic foods. Bread could become more expensive in a matter of weeks, while derived products such as eggs, chicken or pork would do so months later, as the increase in the cost of animal feed is passed on to the entire food chain. Gas, the hidden ingredient. The manufacture of nitrogen fertilizers also depends on another key factor: natural gas. Between 60% and 80% of the cost of producing fertilizers comes from the gas used in the chemical process that transforms atmospheric nitrogen into compounds usable by plants. With the war driving up energy prices and damaging industrial infrastructure, the cost of production skyrockets even before fertilizers reach the market. In a few days, the international price of urea has risen more than 25%reaching levels close to 625 dollars per ton. Risk of global food crisis. I remembered the financial times that the situation also comes at a particularly delicate moment in the agricultural calendar. In much of the northern hemisphere, farmers are starting the season spring planting, when they buy and apply the fertilizers that will determine the year’s crops. If the Strait of Hormuz disruption lasts more than a few weeks, the impact could extend far beyond energy or maritime trade. Thus, what today seems like a localized geopolitical crisis could transform into something much deeper: a global food shock reminiscent of (or even surpassing) the one that occurred after the Russian invasion of Ukraine in 2022. In that scenario, the war in Iran would not only be fought with missiles and drones, but also in the fields of crops half the planet.

If you’ve ever thought about “leaving everything and going to the mountains,” these thinkers have a lot to tell you

In recent days it has gone viralMrinank Sharma’s departurehead of AI Safeguards at Anthropic (that is, the company’s team focused on security, misuse and model safeguards). In the letter that Sharma made publicafter explaining that “the world was in danger”confessed that he was going to the United Kingdom to study and write poetry. The idea of ​​”taking back control of your life” has been in the air for years and has an incredible capacity to mutate and adapt. Yes in 2021 lthose who left work spoke of low pay, lack of progress and feeling disrespected, now we talk about ethical issues and existential anxiety. What persists is that “leave everything and go to the mountains.” AND There are good philosophical arguments for this.. The philosophy of sending everything to hell Cristian Bortes – British Museum Or at least that is what many philosophers throughout history believed. Among the great practical philosophical traditions of Hellenic culture, Epicurism and its proposal to retire to live in peace is perhaps the best-known example. Although it has often been the product of stereotypes and misunderstandings, the school of Epicurus and company understood philosophy as a kind of philosophy of the soul: a kind of, following the ideas of Christopher Gill, a preventive psychological medicine. In this sense, withdrawing, stopping depending on the external, was not a way of being right, but rather of living without anxiety: of dedicating oneself to pleasure. At the end of the day, the epicurean garden that has been painted as an ode to hedonism is, in reality, a search for a friendly place that reduces stimuli, comparisons and needs. In the end, and translating it to our days without all the ontological scaffolding behind it, it is realizing that we are leaving our lives in a race whose goal we have not chosen. Is build a good place to live. However, it is not the only way to see it. independent people Rafael Sanzio Other Hellenic schools, such as the Stoics or the Cynics, were much more radical. Or, rather, hard. With their doctrinal differences, they sought internal independence, autarky. Imported to our days consists of going beyond building a shelter and going on the offensive. Modern life chains us in a thousand different ways (mortgage, career, reputation, schedules, etc…) and, for this reason, retiring goes far beyond a healing practice: it is a practical theory of freedom (liberation). This connects directly with another tradition: that of the hermits and ascetics that goes from Valerio del Bierzo to the eastern saints. There are many ways to justify it, but the idea is always the same: if to sustain your life you need to be liked, be productive and be available, you are not free; You are functional. And being functional to the material world, being functional to the system prevents you from aspiring to higher goals. think better With the birth of the modern world, we began to think about retirement in a different way: as a way of thinking well, of thinking better. The Montaigne tower or Rousseau’s walks have often been seen as a form of misanthropy. But, in reality, they were a way to get away to gain perspective, calm the soul and practice some mental hygiene. It has a lot to do with the idea of ​​disconnection retreats, although since the time of the French solitaries, society has spread its tentacles so much that it has become much more difficult: our minds are always foxes. Withdraw in protest The arrival of modernity also brought us political retreat. That is, leaving as a protest. When you can’t reform the world, sometimes the only lever is the way out. Or, what is the same: if in classical antiquity ostracism was the punishment par excellence, now it emerged as a tool. Refusing to cooperate with an unjust, corrupting or downright absurd order. It is true that much literature considers this type of flight as a sign of cowardice, but it is also true that (lucid or not), it is never neutral. Many reasons, the same gesture Be that as it may, we must not ignore that, in the background, there are always structural reasons: historically, the impulse to withdraw usually intensifies when certain collective sensations invade society: the feeling of the end of the era, acceleration, saturation, existential anxiety, problems of legitimacy. Just what we suffer today. And in the face of this, tranquility emerges as a rare commodity to seek and pursuea way to recover in the current mare magnun. For this reason, many people have begun to understand that ‘going to the mountains’ does not have to be a gesture of evasion, nor a way of disengaging from reality: it can perfectly be a “moral relocation”: a way to become better, to start again, to gain momentum.

Ryanair thought it could build loyalty with a subscription service. Until you’ve remembered what your real business is

“It has cost more money than it generates” With a brief note and the statements of Dara Brady, CMO of the company, Ryanair has confirmed the closure of Prime, the membership program that sought to retain its customers with advantages that have generated greater costs for the company than benefits. The subscription service of the company has not lasted even a year before its cancellation. Surgical. A test, some results eight months later and a decision: close Prime. Ryanair has confirmed that it is closing its subscription program just eight months after it was launched on the market in a decision that is as firm as it is clean. Subscribers will maintain their benefits but those who had not signed up until last Friday, the 28th, will now no longer be able to do so. They report on the company’s website that customers will maintain their benefits “of exclusive savings on flights and seats for the remaining 12 months of membership.” However, the company’s Prime program already has its days numbered. two million. It doesn’t seem like much for a company like Ryanair, but it speaks volumes about the rigorous cost control that the company manages. The statement includes the words of Dara Brady, CMO of Ryanair, who points out that the program has collected 4.4 million euros in subscriptions but that the benefits delivered are greater than six million euros. That is, in the eight months in which the service has been active, the company has lost less than 250,000 euros per month in the new program. Doesn’t seem like much for a company that has obtained 2,540 million euros in the first quarter of 2025. What did they offer? In its announcement last March, Ryanair offered the following benefits For your subscribers: Priority sale on selected flights Exclusive discounts for some flights Free seat selection for the member and one companion To access these benefits, the client had to pay 79 euros per year. According to the company’s accounts, seat selection alone already amortized the investment from three flights a year. With four flights made per year, we would be amortizing 26 euros on average. The subscription extended for a maximum of one year or 12 flights per year. In addition, I had travel insurance to cancel flights due to injuries or illnesses, the delay of other flights or theft of luggage. Of course, those over 70 years of age were excluded from sickness coverage. Unattractive. “With more than 207 million passengers this year, Ryanair will remain focused on offering the lowest fares in Europe to all our customers, and not just this group of 55,000 Prime members.” The closing of the press release published by the company is a clear confirmation of what happened. The most attractive thing that Prime offered was that the customer could choose (and save money) in the choice of seats but it did not even guarantee that two passengers (one being “non-Prime”) could travel together. It is an incentive that has not been attractive enough for a company where the customer looks for the cheapest way to travel and chooses to add services little by little, depending on how much money you are willing to pay. Nothing premium. Ryanair’s test has convinced the company that it has no room to delve into policies that bring it closer to premium or higher-cost companies. Many of the airlines with higher prices offer cards or loyalty services to keep their customers retained, but this way of acting has not caught on among the Irish company’s customers. The reasons are obvious. When someone chooses Ryanair it is because they expect the lowest possible price for a short flight. And you are willing to sacrifice by traveling with less luggage or accepting 100% digital boarding. You either take it or leave it. And Ryanair knows that the customer will leave it when the competition offers that same flight at a cheaper price. On the other hand, customers who are loyal to higher-cost companies obtain other advantages that do receive greater attention on flights of higher cost and time. For example, loyalty cards companies like Iberia They allow access to VIP lounges or priority boarding, secondary values ​​for those who aspire to travel through Europe at the lowest possible price. To this we must add that the high price paid for the ticket ends up subsidizing these companies for the economic effort they have to make to deliver the benefits to their customers.
