GPT-4.5 It is the demonstration that using more GPUS and more data is no longer useful

by

In the last two years we have seen how companies that develop AI models have not stopped showing voracity almost without limits. They bet on climbing and using more data and more GPUS to improve those models. However, there has been a surprise: it turns out that this strategy no longer works. GPT-4.5 will be the last of your lineage. We have always associated with chatgpt with the traditional models “that do not reason”, although in recent times it also gives Access to reasoning modes. Even so, its current base is GPT-4Oand that model will have a last successor. It will be GPT-4.5, which will not be renewed. That is precisely the interesting thing. Climbing no longer serves much. As they point out experts like Gary MarcusGPT-4.5 It seems to be the finding that spending more and more money on climbing, using more and more GPUS and data to train models no longer makes no sense. OpenAi’s hope was Orionwhich aimed to be GPT-5, but it is not: it is (probably) GPT-4.5. Shock against a wall. The jump in performance and capacity It was never the expectedwhich resulted in the deceleration of AI. At least, of the generative AI that does not reason. That of course seems to have collided with a wall, and can no longer improve. We are, in the face of a change of total focus towards reasoning models. It is happening to all. GPT-4.5 is the acceptance of this new reality by OpenAI, but there are many other AI companies that are in the same situation. The new versions of the models “that do not reason” do not just arrive. Grok 3 does not arrive and Xai is staying behindbut we have also not seen Claude 3.5 successor and we don’t know what Anthropic is working. Google just Present Gemini 2.0but the leap in capabilities with respect to Gemini 1.5 is not spectacular, at least if we do not take into account its reasoning version, Flash Thinking. I told you. Experts like Yann Lecun, head of goal, since warning that this strategy of “more data and more GPUS” had an expiration date. Ilya Sutskever, Openai co -leaflet and now with her own startup of AI, It also made it clear months ago. For him the massive training of an AI model using a large set of data without labeling so that the model detects patterns and structures no more than itself, and even trying to do it more and larger, also did not offer too many advantages. So, why spend so much money? If traditional models can no longer advance with that climbing, the question is obvious: why are companies investing billions of dollars in data centers? The answer is diverse. First, the climb is still useful to improve the models and make them behave better and comment less errors. Data centers make sense. But it is also the section of inference: that gigantic infrastructure in which companies are investing is not so much to train models with the traditional approach, but so that hundreds or even billions of people end up using AI in their day continuously. That is the current bet. That live the models that reason. The deceleration of the AI ​​that takes time speaking is not “of the whole AI”, but as we say of the traditional generative models that did not reason. The new models such as O1, Deepseek R1 or Gemini 2.0 Flash Thinking are clearly the trend: increasingly precise and with answers that have more and more quality and really help us to trust them. To do work for us almost “blind.” We have advances in AI for a while. The AI ​​still has a long way forward. That the climbing approach (more Gpus, more data, this is war) does not make much sense, because there are other paths. Many. And that of reasoning models is just one of them.

Apple Watch technology in headphones. Measuring heart rate is no longer just a clock

by

Apple bought Beats Music and Beats Electronics in 2014 and, although the AirPods are still the most recognizable headphones of the company, the development of Beats has not stopped since then. The Powerbeats pro 2 They are the new beatic headphones and, in addition to respecting the hook format that works so much in the sports market, these are the first headphones under the Apple umbrella that land with A curious function: heart rhythm monitoring. These headphones, at a technical level, arrive with cancellation of active noise, adaptive equalization, space audio, Apple H2 chip and total compatibility with Apple devices (hands -free with Siri, network search, link with a single touch, etc.) They promise an autonomy of up to 10 hours Of continuous reproduction, they work with Qi wireless loaders and are resistant to both sweat and water. What is expected of beats that are launched at a price of 299.95 euros. What does a cardiac monitoring sensor paint in headphones Made the presentations, the clear doubt comes in its key specification. These powerbeats are capable of Measure our frequency in real time. They become the first Beats product to incorporate this monitoring. But how do they work in headphones? According to Beats, a lot of development has been invested to design and locate these control sensors. In this case, They are located right next to the padand make green light more than 100 times per second. The company details that the years of research in heart rate control of Apple Watch have been used to continue this development in the headphones, reducing technical architecture to 1/16 of its original size to integrate it into a headset, without compromising comfort or precision. Beyond marketing, Apple has trimmed Apple Watch sensors to implement them in these headphones. And, yes, they will only work if you have both positions. The goal is to offer an alternative to the smart watch, so that athletes can measure their heart rate while wearing headphones. They are a solution for those fashionable sports, such as Crossfit or Hyrox, in which it is not possible to train with a clock placed. Headphones as a health complement Apple has not been the first to introduce heart rhythm sensors into headphones. Amazfit got it in 2020 with its Powerbudssome headphones of less than 100 euros, and Anker sells his Soundcore with a “similar” technology. The quoted is mandatory because, to date, Apple Watch heart rate measurement is one of the most reliable proposals. If Beats has managed to take this technology to its headphones, at least on paper, They should lead this land. Beyond this particular case, these headphones They will be an excellent thermometer. They can be the door that, in the near future, Apple Airpods incorporate heart rhythm sensor. A movement that would make enough sense, seen the clear health approach that the company’s products have.

The lyrics of his students were no longer understood

by

If someone sensed that the digitalization of in teaching was going to be an easy way surely at this point has changed their minds. The introduction of digital in schools seems to be oriented by the old test and error method and the last example has been found in a Catalan school. A new step back. A Catalan school, the Escola Pia de Caldes de Montbui, in Barcelona, ​​has been the last educational center to announce that it turned back in its way to digitalization in the classrooms, according to The newspaper advanced The country. Perhaps the most striking in this case is the reason adduced by the center: the students “reached ESO and the lyrics were not understood.” The strategic twist of the center was also due to other factors in addition to the aforementioned worsening in students’ calligraphy. According to the saying to the environment, they had detected problems such as difficulties when devising titles, saving margins or the mere fact of facing a blank sheet. In addition, students also showed signs of early tired when they should write for some time. As reported, the transition plan implied the delay in the incorporation of computers, first until fifth of primary and later to Secondary. Matteries and activities with computers in favor of paper and pen would also be reduced. Trial and error. The case is another example of something that has become usual, that of the back in the introduction of digital in the classrooms. A reverse sometimes starring educational centers and others, For the same public administrations. Bringing new technologies to students is not a simple task as many have discovered. Getting digital tools to complement and not replace other capacities is difficult. Also necessary. There is no standardized way to introduce these resources, which implies that many times the teaching teams end up giving blind sticks and experiencing until they find with the ideal formula with the old test and error method. Learning lessons. However, there are those who already take notes of this. UNICEF, the United Nations Agency dedicated to childhood protection created A decalogue with considerations to take into account when implementing new technologies in schools. Duties accumulate. While the debate on how to introduce digital resources into the classrooms occurs, technology advances and creates new challenges that add to those we have not yet faced. Artificial intelligence is a clear and recent example of this. In Xataka | Years ago Mexico opted to offer longer school days for children. Caused an increase in divorces Image | Adam Sondel

Years ago Mexico opted to offer longer school days for children. Caused an increase in divorces

by

A time ago a group of economists from the University of Tennessee It was done A peculiar questionfor the concepts and ideas that combines and also its implications: does the school’s school day influence The divorce rate parental? If the time children spend at school clearly affects To the dynamics of the families, conditioning as basic aspects as the hours of adults for other tasks, does that factor interfere with the couple’s breakdown? And if so, how? And why? After crossing school data and separations recorded for several years in Mexico, the experts reached A curious conclusion: The expansion of school days or have greater access to schools with extended schedules does seem to affect divorce rates. It increases them. School Conference (and something else). Over the years articles (many) have been published on how the different school day models They affect To students, their performancehe school abandonment or the “Child Wellness”. The debate It is old and root in a dilemma on which they have run ink rivers: Continuous school day or departure? There are those who ensure that this response has implications that go far beyond the classrooms, such as The gender gapthe Differences of opportunities or family poverty. Click on the image to go to Tweet. A new factor: divorces. María Padilla-Romo, Cecilia Peluffo and Marian Its derivatives: The separations. And they have done it based on a very specific question: how does the expansion of the schooling work affect divorce rates? To find out they basically handle two sources, the statistical records of marriage ruptures and school data on the expansion of the school day in the public primary schools. In Mexico they found databases for both fronts, so the country ended up becoming its particular (and huge) laboratory. The data they obtained and interpretation have just reflected them in An essay Posted in Journal of Public Economics. But what did they analyze? The researchers took advantage of a phenomenon that played in their favor: the “Large -scale expansion” of the model of Full -time school (Full-Time Schools, or etc, with a “Extended Day” of Between six and eight hours) In Mexican municipalities from 2007 to 2016. To be more precise, economists resorted to census data from the monitoring of the monitoring Program etc. of the Secretary of Public Education that corresponded to the 2007/2008 academic year, in which It began to applyand 2015/2016. Then they compared the degree of implementation of that program of school day expanded by municipalities and were fixed in women in divorce procedures in each of those locations. In short, they crossed data. The information on marriage ruptures was obtained from the National Institute of Mexican Statistics and Geography (INEGI), where the cases processed between 2000 and 2016 consulted. And the surprise came. After working with the different records, the researchers discovered that there seems to be A marked relationship between the extension of the school day in the primary centers and the ruptures. At least in Mexico. “We found that the expansion of the school day in 3.5 hours causes a significant increase in divorce rates,” explain economists in Your article. “In addition, the effect is increased with each year of exposure from municipalities to full -time schooling.” A well calibrated trend. The experts They go further and share their calculations on the relationship between both factors, broad teaching days and ruptures. “We found that, as a result of an average increase in the availability of etc. of 24 percentage points, the divorce rate increased by 0.041 divorces per 1,000 individuals (an increase of 12.6 in relation to divorces in the municipalities treated in the year prior to the opening of the first etc) “. Moreover, researchers even appreciate that “the effect increases over time” and the increase in the divorce rate is higher when families enjoy the longest teaching days for seven years. “Our main estimates suggest that the availability of ETC It gave rise to 23,119 additional divorces between 2009 and 2016, or approximately 4.7% of the total number of divorces presented during that period of time, ” The study abounds. Its authors also detected another key trend: the longest school days gave rise to greater divorce rates in areas where less traditional social norms overwhelmed on marriage, divorces and female work. Click on the image to go to Tweet. The question: Why? Extend a few hours the time that primary school The article From Padilla-Romo and his companions suggests that it is not. Maybe it’s a few hours, but influence classrooms. And the reason is that this extension of school days is in its own way “an implicit subsidy for children’s care.” Having their children during a broad period in schools – on its website the Mexican government points out that in etc From 8.00 to 16.00 h– Parents have more time. Especially women, in which It regularly falls The care of the offspring. And those hours can use them in working outside their homes, in exchange for a salary that reinforces their economic independence. Although the researchers recognize that the greatest job among women can have other consequences, such as generating “conflicts”, that mothers with an “abusive couple” remain less exposed to it or simply increase the flow of money that enters home, what That facilitates to face the expenses involved in divorce and separation, the researchers suggest that the economic factor is essential to understand the phenomenon. “A disproportionate fraction”. “Mothers and other female members of the family dedicate a disproportionate fraction of their time to the care of children. The longest school days provide them with an increase in their effective time provision, which translates in better opportunities to acquire individual income “, Zanjan The three authors of the study. “As a result, the negotiation positions at home are probable.” “Our results show that the extension of the school day gave rise to higher divorce rates in areas with less traditional social norms on marriage, divorce and the priority of women in jobs, … Read more

It is no longer necessary to be registered to use chatgpt. And it is another step in OpenAi to be “the new Google”

by

OpenAI has eliminated the need to register to use the chatgpt web search, allowing any user to access their service directly. It is a movement that eliminates friction and democratizes access to its conversational search technology, which was already free. EITHER Freemium. If a few months ago OpenAi allowed the basic version of Chatgpt without registration, now this extends to Your own search engine. The context. This step is part of a broader strategy that we already anticipate: OpenAI wants to become the new Google. The company is transforming from a non -profit research laboratory to a technological giant who aspires to redefine our way of accessing the information. For more than two decades, Google has been almost exclusively our access door to knowledge and information, but Chatgpt’s emergence endangers its position. And in OpenAi they are aware of it. Between bambalins. The company is making a massive investment in infrastructure, building its own data centers in the United States and developing an AI -based search engine. All this while assume losses that exceed 5,000 million dollars annually. The growth potential is enormous: if you no longer need to register to search, it is much faster and more inertial to use it as a Google replacement. Turning point. The elimination of the mandatory registration arrives at a very specific time for OpenAI: it has reached 150,000 million dollars of valuation, and wants to reach 1,000 million users in 2025. That goal would place him at the level of technology giants, and hence a part, surely, the motivation of this movement: reach more people and eliminate friction.

an olive oil so cheap that it is no longer profitable for farmers

by

Between to Huelma’s Sales, in the heart of the province of Granada, there is a cooperative that groups 1,600 olive producers from the nearby regions. It is only necessary look at its facilities To check the real state of the Andalusian olive: they work 24 hours a day and will triple the triple olive that last year. And, paradoxically, this can become a problem. Problem? How will that be a problem? It is true that consumers fall in oil price is somewhat full of advantages. However, everything has a limit. Specifically, the one that sets the fixed costs. From a certain price, farmers lose money: move to the crews, manage the olive, transport it … It entails putting more money than they can enter. How much money are we talking about? And that limit (historically, for the traditional dry land olive tree, is around four euros) is about to be reached. Faced with the nine euros to which the liter quoted at this point in last campaign, the price is already around To that red line. Is this situation normal? In the oil, we have been very bad for years; But this same season we have seen how something very similar happened with The lemons, The almonds either bananas. We have also seen that the wine faces a similar dilemma. If the production does not conform to demand, the problems appear. And it doesn’t matter whether it is on the one hand or another. And what will happen to the price? This is a great unknown, the truth. The big marketers have been accumulating losses for years and this good campaign is an opportunity to clean up their accounts. That means as they defended since Deoleo last campaignthat we are not going to see minimum prices in supermarkets. On the contrary, the actors in the sector maneuver to stop the fall of retail prices. However, market asymmetry in origin causes serious problems To the thousands of producers in Spain emptied. And it is not a futuristic. “There have been times when the liter of extra virgin has fallen to 3.5 euros, which means that in other lower categories it is in three and this is very worrying because the volume of the current harvest does not justify this decrease so pronounced “, The Director of Agrifood Cooperatives Granada explained in Ideal. What can we expect? If the fall in prices at origin does not stop, this can be the lace of the change of productive model that It has been planning for years About the Spanish olive grove. The truth is that the dry dry costs has much larger costs than The irrigation or the Superintensive. After several years with financial problems we can see how many drying farms have to close this due to blockbusters and low prices. That would be many things: a drama for many areas of the country, a substantial improvement in field productivity and huge environmental tensions. Every day that passes, the oil culture has a more uncertain future. Image | EMRE | Emiliano García Page In Xataka | The worst scenario for olive oil has come true: Spain walks towards a black year

when you can no longer buy them and until when they can be used

We are going to explain the times of the end of free public transport passesafter the Congress of Deputies has rejected the Royal Decree in which its extension was included. This also affects discounts of between 30% and 50% on some season tickets, the aid has simply run out. The free public transport passes They were designed for young, minor and unemployed users, and their medium-distance and suburban trips. Meanwhile, the 50% discounts were for long and medium distance passes, and 30% for multi-trip passes and tickets. All this disappears. When do the free and discounted passes end? Subscriptions have run out as of today. Yesterday afternoon the Royal Decree that included these passes was rejected, and Renfe immediately announced that they can no longer be acquired today. It has been immediate and lightning-fast. Today, Thursday, January 23, 2025, you can no longer purchase free passes or discounted passes for long and medium distance or recurring trips. Everything has returned to its original price, after the discounts have been in force since September 2022. What if you already have a subscription? If you recently obtained one of these subscriptions, don’t worry, because you will be able to use them until the end date of their validity. Free passes already issued may be used until April 30and Avant until the end of their validity period. Therefore, this means that you can no longer acquire more free passes or with discounts of 30% or 50%, however, if you already have one you will be able to continue using it until it expires. It remains in doubt whether an extension of these subscriptions will be attempted again, but for now they have ended.

It is no longer independent, it is already connected with Facebook and Instagram

by

If the user can be happy about new updates that allow you to create better statuses with your favorite songswhat WhatsApp has just announced breaks one of the biggest rules of the chat app since it It was purchased in 2014: your independence. Meta has announced that they will be able share WhatsApp statuses directly on Instagram and Facebook. And a line has been crossed that in some way has drawn its own, unique and independent territory, since until now Meta had left WhatsApp outside the ecosystem of its social networks. Everything was in the messaging app private. On Instagram and Facebook the game has been different, since when you create a story you can publish it directly on both (although there is always the option of not doing so). Which saves time between two apps or platforms that are still social networks, but WhatsApp has been characterized by being a private and simple messaging app so that now that feeling is completely diluted security. Instagram and Facebook are two more public social networks and WhatsApp has always remained in the area of ​​privacy and that space that is more personal to the person. Building a bridge with social networks puts uncertainty in what has always been its most important experience: being a private messaging app. Today’s announcement changes everything, as the account center is going to start supporting WhatsApp so that status updates can be forwarded or posted on all platforms where the user has an account. That border has been completely crossed, and in fact Meta has warned that those users who may fear for their privacy should not worry about anything, since none of these changes will affect the privacy and security of their messages. WhatsApp announcement with status updates WhatsApp The Free Android It has also single sign-on support announced in the WhatsApp account, which makes it easier to switch between different platforms. The American company has said that the changes in the account center to support WhatsApp will take time to apply. Goal, according to Engadgethas also confirmed that it will add more features that can be shared across multiple platforms like stickers, avatars and AI selfies; functionalities that it has been deploying last year in several regions. Manuel Ramirez The Free Android Of course, this type of content is currently being stopped by the Digital Services Law in Europe and no type of function related to generative artificial intelligence has arrived in Spain; one of the largest investments that Meta has been making in its app as well as in its social networks over the past year.

Two students shot at Nashville school: shooter ‘no longer a threat’

by

At least two students were injured Wednesday at Antioch High School in nashvillewhen another student allegedly shot at them in the school cafeteria, Metropolitan Nashville Police said. “Antioch High School is on lockdown due to shots fired inside the school building. The metropolitan police are on the scene. Person responsible for shooting no longer poses a threat“said the school district in a release. “We will gather students in the auditorium and provide information about reunification as soon as possible,” they added. The shooter shot himself after the incidentsaid the police in Xalthough they did not offer details about his condition. There were also no details immediately available about the conditions of the other injured students. According to police, buses were taking Antioch High School students to a reunification site at 3754 Murfreesboro Pike. The exit leading to Old Hickory Boulevard from Interstate 24 was congested around noon when several police and emergency vehicles swarmed the area after the shooting. Rep. John Ray Clemmons, D-Nashville, said, “Once again, our community has suffered an unspeakable tragedy at a school that has negatively affected innocent children and families. “We continue to monitor this situation with the Mayor’s Office, MNPD, and MNPS, and will provide more information as we receive it.” “We will be praying for the children who were allegedly injured and for all the Antioch High School students whose lives have been changed forever today. Our efforts will not stop at thoughts and prayers. “We will continue to fight for common sense gun safety solutions that protect our children and communities from gun violence,” he said. Antioch High School is home to approximately 2,000 students in grades 9 through 12, according to its website. The Bureau of Alcohol, Tobacco, Firearms and Explosives said it was also responding.
