O4-mini is much more than another model of AI. It is the Tesla Model 3 of OpenAI

by

The last launch of OpenAI, the models O3 and O4-minihe says much more about his strategy than he seems to the naked eye. The greatness of this proposal-especially that of O4-mini-is not in Benchmarks nor in technical capacities, which also; but in the tactic that raises and that Remember a lot to which he made Tesla In a giant: First came Model sa luxury product that demonstrated what was possible, but accessible to few. 80,000 dollars. Then came Model 3surprisingly powerful but at a price that greatly expanded the market. 35,000 dollars, less than half than Model S but maintaining 80% of its key benefits. With O3 and O4-mini, OpenAi has executed a very similar movement for the world of AI. O4-mini costs just 1.1 dollars per million Tokens input and $ 4.4 per million departure. And offers a performance that rivals his older brother: 68.1% in Swe-Bench compared to 69.1% of O3which costs almost ten times more. This price-reference equation is no accident, but the aforementioned strategy that we have seen before. A “economic” product that democratizes premium capabilities and expands its potential market. O4-mini exceeds Claude 3.7 Sonnet (62.3% in Swe-Bench) costing much less. It is the best model in Aime 2024 and 2025 (elite mathematical contests) surpassing even major systems. Tesla analogy is reinforced when we see that O4-mini allows a user of Chatgpt plus ($ 20 per month) access capacities that previously required Pro subscriptions (200 per month) or Enterprise (thousands). And the master coup comes from integration. O4-mini is the first “mini” model capable of using all chatgpt tools: web navigation, run python code, analyze images and generate them. With a single affordable model, Openai is absorbing use cases for which several specialized suppliers had to be paid. Concrete examples: A startup that makes slate diagrams analysis for $ 50 per month, now competes against a system that does the same for $ 20 per month, and also solves mathematics, program and seeks information. Another that sells assisted programming tools for $ 30 per month faces an O4-mini that writes better code and also visualizes data. This explains Why Openai released O4-mini when Initially he had announced that would integrate this technology directly into GPT-5. The competitive pressure of Claude 3.7 Sonnet and Grok 3 He forced them to accelerate and have shown that they are willing to cannibalize their own premium products to maintain their dominant position. This reminds what Apple did with the iPod: it was not afraid to integrate it into the iPhone knowing that in a five years It would evaporate what generated 40% of its income. Advance or die. The key difference between O4-mini and alternatives such as Claude is very clear: while others offer larger models that consume more resources, OpenAi has achieved a compact model with sufficient performance for almost any practical task. In the same way as the Model 3 It did not need autonomy for 600 kilometers when 350 were enough for the majority, O4-mini does not need the last 5% precision when it already solves 95% of everyday problems. It is not just a technological strategy, but of scale economy: With each new user, the marginal cost decreases while the competitive advantage increases. And as Tesla, when the competition tries to react by copying its approach, Openai is already announcing its next movement. Of course, as is happening to Tesla, The Chinese threat In the medium term it is unpredictable. In Xataka | Openai’s hypothetical social network does not want to connect people.

Grok will also remember all our conversations with him. The new generative AI tendency is already here

by

XAI, Elon Musk’s company, has announced The incorporation of a memory function for its Chatbot Grok, which can now remember details of past conversations to offer more personalized answers. Why is it important. Memory integration is a huge step in the evolution of the AI ​​attendees, transforming them to tools for specific tasks to digital partners who learn and adapt over time. This update reduces Grok’s gap with its rivals. Chatgpt It has been offering a similar but newly improved function for some time to be able to refer to the entire user conversations history. Gemini also has persistent memory to customize your answers. In detail. This new function allows the assistant to retain previous interactions information. You will remember whether we told him that we only want to use Python to program or if we ask for advice to improve running from concrete MMPs. The function is available in beta through Grok’s website and its mobile applications, although it is not yet accessible to users in the European Union or the United Kingdom. The context. Grok 3 already stood out for its speed and intelligence, but as we said at the timeIt lacks elements that make it attractive to recurring and professional use, compared to competition options. I had nothing similar to projects, GPTS either Gems. It still does not have it, but at least now it goes further in product development with a persistent memory. Between the lines. The implementation of memory implies a huge change in human relationship. It allows you to move from the unique and state consultation model that characterized the first systems of AI towards more continuous relationships that are built over time, which they remember. The AI ​​attendees go from being specific tools to becoming digital partners who know our preferences, history and needs. How it works. XAI has emphasized transparency In memory management, allowing users: See exactly what information Grok remembers. Disable the function from the configuration. Eliminate individual “memories.” And now what. The question is whether Grok is going to get thanks to this novelty differentiates himself in an increasingly competitive space or if he will be relegated to punctual anecdote in a saturated market. Xai still has to show that Grok can make something differential and real useful on a day -to -day basis, not only in specific uses closest to hobby. This is a great step in that direction.

The “natural wine” has become fashionable. There is a place where he takes centuries without so much hype: Mass

by

In 83, Juan Pablo II visited the prison of Rebibbia, in Rome, and hugged Mehmet Ali Agcathe man who had tried to kill him a couple of years before the Plaza de San Pedro. In 89, a crowd accompanies the coffins of Jesuit parents killed in El Salvador. In 2016, in the middle of Holy Thursday, Francisco washed the feet of a group of refugees from the center of Castelnuovo di Porto … There are many iconic images around the Catholic Church. But for me the image that has impacted me the most happened a couple of years ago: when I saw the priest of my town, dressed in its clerriman, buying a tetra brick of red wine in the Mercadona. Had he found the origin of Mass wine? I had never wondered where the wine that was used in the Eucharist came from and, I suppose that for that reason, that image left me completely out of charge. And as normal, a question immediately approached me: “Was it possible that this was the wine that was used in Mass?” The answer, in case there is any questions, is: no. And here this article could end: with an anecdote of Berlanga that ends “fish -shaped“But no. Because, little by one that one starts to investigate, the history of sacred wine is really interesting. Sacred wine? Although it is true that the Catholic Church (and Christianity in general) has done a lot to take wine to any corner of the world, the sacred history of this type of broths is very long. In fact, Jesus of Nazareth came to ‘resignify’ a good handful of religious signs of common use. What is true is that it is not causality that most historical vineyards are on ecclesiastical terrain. Nor is it a coincidence that the development of the wine industry is intimately related to the comings and goings of the missionaries. Nor that the Vatican is the country that consumes the most from the world (about 45,000 liters a year for its 800 inhabitants). Wine and church have always been closely linked. And, for that reason, not any wine is worth it. Over the centuries, different criteria have been developed to know if a wine was likely to be used in the Eucharist. It is something that has been discussed extensively even in councils Like Florence of 1438. However, it was not until the nineteenth century when the Church (with the industrialization of the world of wine) began to take the idea of ​​establishing criteria that ensure the liturgical purity of wine. In fact, until 1959, as was the case with other things such as togas or candles, there were ecclesiastical certificates very difficult to achieve. The first certified wine was, in fact, Spanish. Prepared by Augusto de Müller Ruinart de Brimont, an Alsacian Even today is a reference in the sector. Maybe Do not be the best sellingworse is the one who has the most history (and It costs less than seven euros). In search of purity. The current Roman Missal is quite clear Around the wine that can be used: “It must be the result of the mature or passage grapes and without artificial additions such as preservatives, dyes, sugars, clarifying or juices. On the other hand, sulphites such as antioxidants or wine distilled to increase alcohol content, which should not exceed 18 degrees,” are allowed to add. The idea is to produce a wine that looks, in one way or another, which it has been using since time immemorial. The problem is that this means challenges that new wine techniques and enologies try to solve: The natural wine boom is part of the same game. Innovation that a bottle of natural wine can be surprising is still surprising. The color and taste depend on the winery. And from which he buys it. A background lesson. Because beyond the curiosity of who produces a product like this, the history of Mass wine tells us about how technological development is truffled with values, ideologies, religious beliefs and social configurations. Here it is seen in a simple way (the composition of the wine consumed by millions of people is discussed in ecumenical councils), but it is not so different from what operates in the natural wine that so fashionable has been put. Not many of the technological decisions of our day to day. History is always more complicated than it seems. Image | Mateus Campos Felipe In Xataka | Andalusia is very proud of its Holy Week.

What are they and how to manage or delete the key data that you remember about you and use in all chats

by

Let’s explain What is the chatgpt memory and howa system with which artificial intelligence remembers several key data about you. Because now Chatgpt remembers things you talked in the past, and will take them into account to use them in the future. We are going to start the article explaining what exactly is the chatgpt memory, telling you what it is for and putting some examples about your operation. Then we will tell you How to manage stored memories that you have from your chats to be able to erase some or all. What is the chatgpt memory Chatgpt is now capable of Remember useful information about you that is extracting from the conversations you have with him. For example, if in any conversation you tell him what your musical tastes are or where you work, the AI ​​will remember this information to use it in future chats. Each data of interest that Chatgpt keeps on you is a memory, and the chatbot stores memories with which to have these relevant data. The idea is to be able to Offer more personalized and relevant answers taking into account the context of the data about you. For example, something funny that happened to me. At a specific moment I spoke with Chatgpt about a musical group that I liked a lot. I said it passed, I think that to ask for some illustration or drawing with his name. He recalled this, and a few weeks later I asked to reimagine a photo of mine in the Ghibli style, and in the drawing he put me with the shirt of this band. There are two ways in which Chatgpt stores memories. First, it can be from normal conversations when you mention key data. But also You can ask you to remember something telling him to remember something, saying for example “remember that my favorite color is black.” You have control over Chatgpt’s memories, and you will be able to eliminate them individually or reset all erasing them. You can also deactivate this function so that you do not remember things or using what is remembered. And if you have it activated but want to start a chat that does not take into account the memoryyou can do it with the option to start a temporary chat. How to review and eliminate memories To review and manage the memories stored in chatgpt, you have to enter the configuration of this artificial intelligence. You can do it from its official website or from mobile and computer applications. Once within the configuration, Enter the section of Personalization. Here, under custom instructions You have the options for Memory. You can deactivate referring to the stored memoirs in the event that you do not want them to be used in your chats, and below you will have the option of Manage memories. If you click on Manage memorieswill be shown A list with all stored memories In chatgpt. In it, you can read what you are remembering in each one, and you will have to the right the option to erase the ones you want. You also have a button to eliminate everything if you want to forget everything you are remembering.

If the question is which car will not leave you lying on the road, the German experts are clear: the electric

by

More and more drivers They bet on electric cars And, with it, the Reports about your reliability They become more precise and complete because they provide more real data on the wear of their pieces over time. He last analysis of the ADAC, The main automobile club in Germany has thrown surprising data on the frequency of roads on the road, comparing electric and combustion vehicles. We have a clear winner. Thrown on the road. He ADAC studymade from millions of road assists, reveals that electric cars have a lower breakdown rate than their fuel or diesel combustion counterparts. This data is essential for those looking for a reliable car and with less possibilities of stay on the road. The analysis is based on 3.6 million road assistance operations, of which only 43,678 went to electric cars, which represents only 1.2 % of the total. Although the percentage of electric cars in circulation is much lower than that of combustion cars, the fault ratio remains well below compared to the thermal models of the same antiquity. The data leave no doubt. Adac data has only taken into account cars of which, at least, 7,000 units have been enrolled in Germany in the last two years, which leaves a sample of 160 models of 20 brands other than two and nine years old. If vehicle data is compared four years old, the Road Assistance Service It served 8.5 electric cars damaged by every 1,000 existing cars, compared to 12.9 combustion cars per 1,000. For cars between two and four, the difference is even greater: a ratio of 3.8 breakdowns per 1,000 electric versus 9.4 per 1,000 combustion cars. These numbers show that the electric ones fell half that the thermal models. A simpler mechanic, less breakdowns. The main reason for this difference lies in the Mechanical simplicity of electric cars. Having less mobile components and mechanical systems, there is less likely to suffer a breakdown that requires road assistance. For example, electricity do not have traditional gearbox or complex exhaust and cooling systems, which significantly reduces critical fault points. However, the most common breakdown in both types of vehicle remains the 12V auxiliary battery that tends to be downloaded more easily due to use in starting systems and the greatest demand for electronic systems. In the electric, 50% of the faults are related to this component, while in combustion the 45% of the assists. Tesla leaders, Hyundai to the tail. The ADAC report also analyzes reliability by brands and models. The data show that Tesla is the brand with less incidents registered. Thus, the Tesla Model and has a ratio of only 0.9 breakdowns per 1,000 units and Model 3 drops to 0.5 faults per 1,000. Other highlighted models in this section are the Volkswagen ID.4 with a ratio of 1.0 and the Audi Q4 e-tron with 0.7 failures per 1,000 vehicles. On the opposite side, as a vehicle with more registered assists, there is the Hyundai Ioniq 5, which in two -year -old cars has registered 22.4 breakdowns per 1,000 vehicles. Discordant notes. Toyota, considered one of The most reliable brands In different reliability rankings, it obtains a alarmingly high assistance ratio in its Yaris and Yaris Cross models. According to the study authors themselves, Toyota has already taken letters in the matter indicating that it is an incidence in the 12V battery configuration that discharged them, but that was solved in the new units produced in 2024. The data obtained by ADAC contrast with the Obtained in the Itv German (Tüv), where the Tesla Model 3 was the electric with the most failures detected, especially in headlights, brakes and suspensions, being below brands such as Dacia in general reliability according to this organism. The electric approve with note. The electric car market is relatively recent, so Adac clarifies that its conclusions are based on data data with an age of between 2020 and 2023, many of them being the first versions of their models. That leaves a current photograph but still limited in time. As increase the electric car park and These vehicles agethe records will be increasingly precise and complete, allowing to detect problems of long -term reliability. However, these results already allow an idea of ​​the reliability offered by the electric car and the evolution it will have in the coming years.

We thought they were the red color in a galaxy he indicated that he was dead. There are those who believe we are wrong

by

A simple and useful way of knowing if a galaxy is old or if on the contrary it is full of new star formations is in its color. The rule is simple: the most reddish galaxies are usually older; The most bluish, young. Young and red. Now a researcher at the University of Missouri has raised a third waythe possible existence of reddish but still alive colored galaxies, that is, in the process of forming new stars. Among other implications, this could mean that our universe forms even more stars than we thought. Red or blue. Galaxies are usually categorized according to the color of their stars. Blue stars usually shine with more force for less time, so when the blue tones predominate we know that new stars are still forming. The stars with warmer tones resist more so when a galaxy dies, that is, when it stops creating new stars, these more reddish stars are what remains. However, there is something that escapes us in this hypothesis. According to Charles Steinhardt, author of the new study, this model raises certain inconsistencies, for example in the ratios between stellar masses and masses of black holes, and enters the initial mass functions of red and blue galaxies. What if they are not dead? In An article Posted in the magazine The Astrophysical JournalSteinhardt raises the existence of a different category, red and young galaxies. The key would be in the fact that in these galaxies, the stars formed would be of less dough and that therefore, also the youngest would shine with reddish tones. “The red -star formants mainly produce little dough stars, which would make them look red despite the permanent births of stars,” Explain in a press release Steinhardt. Birth and fusion. One of the keys to this hypothesis is in the post-stallid galaxies (Post-Starburst). The galaxies can go from being young stars producing to lifeless galaxies in two ways. The first, through a slow and natural evolution; the second, after a burst of stars (Starburst). When two galaxies collide, the subject of both meets, accelerating the accumulation process that gives rise to new stars. This makes the galaxy go through a stage of rapid stars formation, a stage that leaves the galaxy without fuel. In his hypothesis, Steinhardt raises the possibility, that some of these galaxies have been forming red and small stars from the beginning, and not being the result of a burst. This possibility would imply, Explainhave to reclassify some of the galaxies we know. More stars. The new hypothesis postulates that red galaxies continue to create new stars which in turn implies that our universe produces even more stars than those we believed. “The existence of these galaxies can mean that the universe has formed a significantly greater number of stars than before,” Steinhardt defends. The galaxies are complex formations and we may still notice important details about them. Details such as the details of their life cycles, adds the researcher.

The world’s most expensive coffee cup costs 300 euros and is sold in the only country willing to pay something like this: Japan

by

He price of a cup of coffee It is an excellent socioeconomic indicator. That “1.20 euros” of a coffee with milk in a conventional bar is the measure of measuring with which many Spaniards in recent years have compared the Daily Products Pricebut that rod has long since broke. The boom of chains like Starbucksspecialty coffee shops and trembling reality of the coffee market has caused the price of this delicious and healthy drink increase dramatically. But even if we pay more or less depending on the place where we live, there are so exclusive cafes that does not matter where we take it because its price will continue to be crazy. And one of those expensive coffees occurs on the Japanese island of Okinawa. The price? 315 euros. The cup, not the kilo. And even the most coffee experts do not know if it is worth it. Coffee that costs a third of the minimum wage We are talking about asking for a donut of a couple of euros to accompany a cup of coffee of more than 300 euros. It is complicated that many of us imagine something like that, but it is what happens with some coffees such as Nakayama Estate. And, within that it is a barbarity of money for a cup of coffee, I will turn to that xataka meme: it makes sense. Put the quotes you want here. Okinawa is just at the north limit of the so -called ‘coffee belt’, which makes it one of the most extreme areas where it can be cultivated. We have already told that coffee occurs mostly in what we know as the “coffee belt” and that, although the Climate change It is allowing coffee to develop in areas Like Sicily either Spainit is still a peculiarity that coffee occurs so to the limit of the optimal zone. In addition, Nakayama is not too high above sea level. To grow coffee, especially the Arabic varietywhich is usually used in the specialty coffee, the altitude to which it is grown must be between 1,000 and 2,000 meters above sea level. In Nakayama, farms are between 150 and 500 meters. To round the formula, it must be taken into account that they use sustainable practices without pesticides and with Japanese employees who charge higher wages than those that farmers from other coffee producing areas can collect. In summary: they are not the ideal conditions, it is difficult to harvest and the wages are high, which directly impacts the price, but there is more. Nakayama Café is not only exclusive for the achievement of carrying out such a harvest, but for the low production they get every year. Brazil is the main coffee producer and in 2022 that production was more than 3,100,000 tons. Vietnam is the second, with almost 2,000,000 tons that same year. New Caledonia is one of the most producers weakwith two tons of coffee. Nakayama would not enter the graphics, because its production is 300 kilos a year. And if we add that very scarce annual production with the factors mentioned above since coffee has distinctive notes thanks, precisely, to that low height crop, we result in a cup that is exceptionally expensive. I would be unable to distinguish a cup of this select coffee from my coffee in Costa Rica every morning, but someone can: James Hoffman. We have ever talked about him, since he was named better barista in 2007, he has such interesting recipes –I have tried this– like that of a Donut coffee and, in addition, It is coffee toaster. It has, in short, a palate qualified enough to analyze something like a cup that costs more than 300 euros. To do this, he went to one of the most expensive coffee shops: Shotin one of the most exclusive neighborhoods in London, to try this coffee. There are only special coffees, such as private crops of islands like Kona in Hawaii, Santa Helena Café (one of the most remote islands in the world) coffee Kopi Luwak that is extracted from excrement from an animal and, of course, that of Nakayama. The letter has no prices, and we already know what this usually implies. Ok, very good, but … is it worth it? According to HoffmannNo. Not quite. “It is more acid than I expected and has a good texture, a touch of wood and is very fruity,” says the British YouTuber. “The barista has done really well, there is a good barista after this coffee and it is a mature coffee, well -processed, well roasted and well done, but I do not think that its flavor and its price are connected.” In addition, he adds that he does not think he has distinctive characteristics of other low -altitude coffees that he has tried. And, although this may seem devastating, really, as I said before, it makes sense. Because, as Hoffmann, the price and perception of those 300 euros for a cup of coffee (espresso, in addition, without milk), depends on the value that we give to things, something that is linked to the size of the portfolio. It occurs with virtually any product whose price is not objective and depends on what we are willing to pay. This Okinawa coffee, better or worse, is like an exclusive wine, fashion brands, chocolate, watches, cars and What can occur to us. Because, obviously, Shot has not cost so much money, but has revalued to the extreme the price of that coffee due to the aura of exclusivity that has to be of the few coffee shops in the world that has those grains in particular. The truth is that, after writing this, I still escape from my head to pay 315 euros for an espresso and I don’t know how many Bernabéus equivalent. But I know that for the price of that espresso, you can buy three games of Nintendo Switch 2 and you have left over for a coffee from the street end. … Read more

Webb telescope has been looking for extraterrestrial life for years. He just found the strongest signal so far in K2-18b

by

The finding. An international team of scientists, headed by researchers at the University of Cambridge, has just made public sulfide detection or dimethyl disulfide in the atmosphere of the exoplanet K2 –18B, which has been observing the James Webb space telescope. On earth, these molecules are only produced by living organisms, mainly marine phytoplankton. It is the strongest evidence so far of a biofirma, a sign of possible extraterrestrial life, outside the solar system. To confirm it, they will take between 16 and 24 hours of observation with the Webb Telescope, according to the study published by The Astrophysical Journal Letters. What is K2-18b. It is what is called a “subneptune”, a planet of 8.6 times the dough and 2.6 times the radius of the earth that orbits a red dwarf in the habitable zone (receiving a flow of energy from its star similar to the earth). It is 124 light years from us, in Leo’s constellation. He is also a candidate for planet Hacéano, worlds that could house global oceans under hydrogen -rich atmospheres. Webb’s first observations have already detected methane and carbon dioxide, which fits with this scenario. Reasons for optimism. When the planet passes in front of its star, part of the stellar light crosses its atmosphere. Each molecule leaves a pattern in the spectrum that scientists associate with molecules. Scientists They have seen twice the same pattern since 2023 With the Miri instrument of the Webb. We are facing the first coherent biofirma on a planet outside the solar system. Life could be more common than we think of planets greater than Earth. The planets made us would enter our external life search radar, today focused on rock worlds such as superstierras. Reasons for caution. Although on earth dimethyl sulfur is biological, researchers admit that in a world under high pressure and with an atmosphere of hydrogen, it could be the result of exotic geochemical reactions. They will need laboratory experiments and models to check.

The information, Posted by Bloomberg earlier this weekalso points out that Chinese airlines will not be able to acquire equipment or pieces related to aviation to US suppliers. When a scenario like this is raised, it is easy to think that the closure of doors to Boeing and other American manufacturers can translate into an opportunity for firms such as Airbus or Comac. And, in part, it is. However, it is convenient to clarify: while Airbus’s main challenge is to increase its production capacity, in the case of Cabel the difficulties are deeper. The United States, in fact, could dynamite its most ambitious project overnight. As? Let’s look at the details. A plane with too many pieces borrowed In recent years we have seen how China has managed to make a decisive leap in multiple industries. One of the most obvious examples we have in front of our eyes: the automobile sector. For a long time, Chinese cars dragged a questionable reputation and a little competitive offer. Today the situation is very different. Something similar could be happening in commercial aviation. Although Airbus and Boeing continue to lead with slack, Cabe has been trying for years A hole in that historic duopoly. One of the key pieces in this important objective is the Comac C919a plane designed and assembled in China with an eye on competing directly with the Boeing 737 Max and the Airbus A320. With capacity for between 158 and 192 passengers and autonomy that ranges between 4,075 and 5,555 kilometers, its current deployment is still limited. However, if we attend to the growth rate of the Asian giant, everything indicates that it is a matter of time that the C919 is also consolidated outside its origin borders. But the project drags, at least for now, an Achilles heel that often goes unnoticed: a deep dependence on American technology. That’s how it is. The pride of Chinese aviation, the most ambitious development of its entire history in this sector, works thanks to key components manufactured by a rival country. For years, these pieces have crossed the ocean without major obstacles. But a block could hit the very heart of the Chinese dream of having its own regional reference plane. So what pieces are we talking about exactly? To understand it, it is convenient to go to Leeham News and Analysis worka specialized firm that has been closely following the ins and outs of the aerospace sector. Flight data recorders – General Electric (United States). Meteorological radar – Rockwell Collins (United States). Communications and Navigation Systems – Honeywell (United States). Antihielo Ala – Liebherr (Germany) system. Aluminum components for fuselage – Arconic (United States). Motors – CFM International, a joint venture between GE (United States) and Safran (France). Thrust investors – Safran (France). Fuel System – Parker (United States). Fire detection – Kidde (United Kingdom). Wheels and brakes – Honeywell (United States). Tires – Michelin (France). Landing train – Liebherr (Germany). Cola y Alas – Aviation Industry Corporation of China (Avic) (China). Just check the previous list to measure the blow that would mean the lack of any US component in the C919 assembly chain. Leeham News and Analysis already warns that the trade war threatens the project. In the same line is Ron Epstein, Bank of America analyst, who declared Reuters: “If China stop buying aeronautical components from the United States, the C919 program will stop or die” The current situation and future perspectives In recent days, the commercial war has intensified with rapid and unpredictable movements. And the truth is that half the world – individuals, companies, governments – still tries to understand how far their effects come. If we focus on the order of the Chinese government on aeronautical components, everything indicates that, for now, it affects only airlines. That would leave manufacturers such as Comac with margin to continue buying the pieces that need the United States. At least for the moment. However, The 125% retaliation tariff (that, added to the previous 20 % in the fentanyl case, leaves the invoice at 145 %) governs for imports from the United States. That includes engines, plane or brakes that Comac buys for their C919. The practical result is that each US component would cost me almost twice and a half its original pricea scenario hardly aware of any manufacturer who aspires to maintain the viability of your business. It is time to wait to see what all this flows. If the barriers imposed by both powers will fall and the trade will be reactivated. But there is also another scenario: that the United States imposes export controls on key components for Chinese aviation. He already did it with the Nvidia chips to stop his advance in artificial intelligence. This situation could reinforce China’s bet to develop your own key technology, although it still has a long way ahead.
