How to create a game with multiple choice questions on any PDF to study with the help of artificial intelligence

by

Let’s explain to you how to create an interactive multiple choice game to help you study anything. We are going to do it with Claudeand you will only have to upload any PDF with the theme you want, and the artificial intelligence It will process its content and ask you questions about it. For this we are going to use the Claude’s artifactswhich means that they will be fully interactive games. In our case, it will be a test type, with several answers of which there is only one valid. So, if you click on the correct answer it will tell you that it is true, and if you click on the incorrect one it will correct you by giving you all the information about why it is not like that. The positive part of using Claude is that you only need a prompt and it will generate the game artifact for you. However, you should keep in mind that all PDFs you upload will be processed by AI, and that could be stored on servers of the company. Therefore, be careful about uploading files that contain private information. You should also keep in mind that AI is not infallible, and that there may be errors and hallucinations, so it is advisable to verify the answers by other means. In addition, you must also make sure that the PDFs you upload have accurate information. Create your multiple choice question game The only thing you have to do to create your game is write a prompt with which ask the AI ​​to create an artifact and describe the type of game what you want You can start with something simple like the following: I want to create an artifact. This artifact will take the information from a PDF that I upload, and will generate a series of multiple choice questions to learn the content. You will do this using Claude, who will analyze the content of the PDF, detect the most important themes and then generate the questions. Once you write the prompt, Claude will generate the game in a few minutes. At the top prompt you can specify anything you want about the game, both specific mechanics and adding a scoring system such as the number of questions or even the colors of the buttons. Then, on the left side, a window will open where you will be able to start your game. For that, the normal thing is that you simply click on the indicated option and upload the PDF from which you want the questions to be generated. Then, in my case I had to choose the number of questions, and then click on the start button below. When you upload the content and start the game, Claude will begin to analyze the content of the documentunderstanding what it says and based on its information to generate questions. After analyzing the content, the game will start asking you questions. As we have asked it to be a test typeit will ask you questions with several possible answers, and you will have to click on the one you consider to be the correct one. If you got it right, it will tell you. But if you fail to choose the correct answer, it will also indicate the failure. In my case, below the correct or incorrect answers, a fragment of the text appears in which it tells you the correct answer. It is not necessary to stay with the first result. If when you try it you are not convinced, you can return to the conversation and ask Claude for changesspecifying the things you want to change or those you want to add or remove. It will then regenerate the artifact from scratch with your instructions. Save your device to use whenever you want Once you have the device to your liking, in the upper right part of the screen you must click on the down arrow button next to where it says Copy. When you do it, click on the option Publish artifact. This will upload your creation to the servers and keep it saved. By publishing your artifact, anyone will be able to find it, and you will also be given a link to share it. But most importantly, in the artifacts section there is a tab Your artifactsand when you click on it you will see all those that you have created. This will be a good way to reuse the game you created whenever you want. In Xataka Basics | Claude: 23 functions and some tricks to get the most out of this artificial intelligence

The Galaxy Ultra already had a scandalous screen. The Galaxy S26 Ultra directly changes the rules of the game

by

I don’t want to waste my time talking about seniority, but I’ve been dedicating myself to current technology and video games for more than a decade and I can say that, at this point, few things surprise me. There are evolutions and functions that are cool, but on very few occasions it is something groundbreaking. Then Samsung arrived with the screen of the Galaxy S26 Ultra and its privacy mode. And I tell you what it is one of those things that you have to see to believe. In the first impressions of all Samsung Galaxy S26 We have already told you the essentials. The South Korean company has put a lot of effort into providing its new models with artificial intelligence functions. According to their estimates, more than 80% of users see value in the features of AI and we have a call assistant to avoid the SPAM, agents who perform actions for usa photo editor to which we give commands with prompts and other functions that make more or less intense use of AI. However, what I have noticed the most is something done so that you do not ‘focus’ on the screen of the one next to you: the new privacy screen. It is a mix between software and software that is explained simply. Have you seen one of those tempered panels that are tinted so that they can only be seen from the front so that curious people can’t see anything? Well, that’s what the Galaxy S26 Ultra screen does. Yes with him S24 Ultra they introduced an anti-glare screen that worked very, very wellthey have now added another layer of technology and functionality. The operation is simple and has to do with the pixel matrix of the OLED panel. We have pixels that emit in a narrow spectrum and those that emit light in a wide spectrum. When privacy mode is not activated, the screen lights up all the pixels, allowing it to look great both from the front and at any angle. But, when we activate the new privacy mode, pixels that emit light in the wide spectrum are turned off. And that’s the trick. When that happens, as users, we notice that the brightness drops a little, but also that we can only see the screen if we are completely perpendicular. If we start to tilt the phone, we quickly lose the angle of vision to the point that at 30 degrees it is very difficult to see anything. In practice, whoever is next to you on the couch, on the train or on the bus, will not see anything at all on your screen. And this is great in terms of privacy, but also in terms of security. Because let’s see, you may be thinking that it is ideal so that no one sees your conversations. Telegram or a mischievous eye that tries to take a look at the gallery or the bank app. And yes, it’s useful for that, but also so that your PIN or important notifications don’t get caught. Because There are three ways to activate this mode: Activated at will in full screen. Activated when we run certain apps in full screen. Notifications only. For example, I don’t care if they see my Telegram, but I don’t care if they take a look at my photo gallery. So I can set it to turn on when I open the gallery and turn off when I exit. But, also, I can add another condition: When there is an app that asks for my PIN, it is automatically activated to hide the process. And the truth is that it works like a charm: it’s fast, transparent for the user once we configure it for the first time and… you don’t see anything, really. I know it sounds very “source: believe me”but in the photos and video above you can see it in operation. In addition, it is not tied to Samsung apps, but to anyone. And it also works with notifications, hiding only the notification bar at the top. Now, it has a catch. You may have noticed that I said “the screen of the Samsung Galaxy S26”, and there is a reason: It is a technology reserved for the most expensive model. We already saw this with the anti-reflective finish of the S24 Ultra and it is a decision that I understood. It is logical that manufacturers save exclusives for their most ambitious models. However, here we are no longer talking about a function to keep gossip away: we are talking about something focused on improving privacy and security. I think that little brothers should have it. What’s more, I think all brands should step up and copy this function. It’s going to make cell phones go up in price, yes, but the truth is that I prefer something like this to cell phones that are increasingly more and more powerful and with more and more –very expensive– RAM for AI functions. From now on, this Samsung ‘invention’ has become something to which I am going to pay close attention. And surely there is someone who doesn’t like anything: to manufacturers of tempered glass with privacy function. Because I have one from a very well-known brand and it works well, but it is a pain in many circumstances and, in addition, it interferes too much with the brightness sensor. That does not happen in this Samsung implementation.

how to install any game or application with PlayCover

by

We are going to tell you a method with which you will be able install any iOS app on Mac, using an open source program called PlayCover. What this application does is allow you to install applications from their IPA file, which is like Android APKs or Windows EXEs. This is a method with which you can do what Apple doesn’t want, but It also has some negative aspects that is worth knowing. We’ll start with them, and then we’ll tell you how to proceed. What’s wrong with PlayCover The main negative aspect of PlayCover is that we will use the IPA applications for the iPhone or iPad. These are versions of applications that have not been optimized for macOSwhich means they may not be able to be used correctly. In some cases, such as the Instagram app, we will find that we cannot click on the login fields, because they are touch-sensitive. The apps also do not adapt well to the size of the windows, and in general the operation can be far from optimal. Yes indeed, iPad version is launched of the applications something to take into account regarding their size. PlayCover is an application that is in constant development, and they ensure that its objective is that all applications work natively, and even be able to use controllers with the games you launch. The tool is open source and totally secure, and compatible for Macs with Apple M chips. Furthermore, the other drawback is that you will have to get the IPA files yourselfalthough there are pages like decrypt.day which are repositories where you can get them. There will always be a risk that applications come with malware or bugs, so extreme caution is advisable. How to use PlayCover The first thing you have to do is enter the PlayCover website, whose address is playcover.io. In it, you can go to the downloads section and download the latest available version. Install the file you download like any application. Once you open the application after installing it, you have to go to the section Applications. In it, click on the + plus button or on Import IPAand choose the file that you have obtained from an application or game on your computer. Then PlayCover will proceed to install the app on your Mac natively. When the application or game is installed, it will appear in the Applications with its icon. You can install more by clicking on the + button that will appear at the top. And that’s it. By double clicking on an installed application you will launch it on the Mac. Sometimes it is advisable to maximize it so that it takes up the entire screen and you can see it in its entirety, because in the window with which they open sometimes part of the interface is covered.

The few video game magazines that remain in print have retro content. That’s why ‘Micromanía’ returns in sheet format

by

In times when the traditional video game press, on paper and sold in kiosks, has practically disappeared from the map (only with some glorious exception that barely resists), products aimed at the nostalgic waterline of the most veteran players are, however, in very good health. They know it well in Made with Pixelswho publish not only a magazine dedicated to retro (‘Pixels‘), but also official continuations of kiosk icons such as ‘microhobby‘ and now, ‘Micromania‘… in sheet format! Two-year hiatus. In January 2024, just over 24 months ago, the veteran ‘Micromania‘, the magazine of microcomputers first, PC later, which would accompany several generations of gamers. Its first issues, in traditional format, covered current 8-bit machines such as Spectrum 48K, Amstrad CPC and Commodore 64. They revolutionized newsstands with their second stage, the most iconic, in a tabloid format that multiplied the content and served as a bridge to 16 bits. A third stage, again in a traditional format, would focus on the PC world. A mixed return. In this new incarnation the format will be somewhat smaller: 25cm x 35cm, that is, larger than any other magazine, but without reaching the brutal excess of the original. The magazine will be bimonthly, and can be purchased in digital format in PDF (5.99 euros), in paper (11.99) or both (13.99). The layout and design are inevitably reminiscent of the original style and the contents will be comparable: analysis in the classic style of Amiga, Atari ST, MS-DOS, Game Boy, NES, Master System, Mega Drive, SNESm, etc., arcade games, news on the current retro scene, solutions and maps… What’s in number one. For now, the contents of the first issue that we know are: Cover dedicated to Monkey Island, with report on Ron Gilbert and the complete saga Two gift posters on the central pages of each issue in giant size Damned Castile Requiem– Exclusive review and downloadable demos for Mega Drive and Dreamcast Interviews with original editors of Hobby Press (Microhobby, Micromanía, Hobby Consolas) Reunion with Turbo Girlset of the first cover in sheet format, 38 years ago Who is behind. Without a doubt, this is the most interesting detail of this proposal: behind the writing of the magazine there are a good number of names from the classic age of video game journalism in Spain, which guarantee that the style of the reviews and articles will be in line with what was done then. It is directed by José Luis Sanz, who was already in charge of ‘Hobby Consolas’, and he is accompanied by Marcos García, who directed magazines, paradoxically, in the competition: ‘Superjuegos’ and ‘Revista Oficial Playstation’, among others. They are joined by editors such as Jesús Martínez del Vas, José Luis Rodríguez, J. Luis Molina and Juanjo Muñoz, among others. Bet on the past. As it could not be otherwise, the magazines that survive on paper, with few exceptions, rely on retro content, or at least retro has a strong presence in their pages. In addition to the aforementioned Hecho con Pixels titles, publications such as the Spanish edition of ‘Retro Gamer’, also by Axel Springer, are added. The new incarnation of ‘Micromanía’ is aimed, obviously, at those who bought it at the time: a juicy market of forty-somethings looking to return to even the most spectacularly uncomfortable format in the history of our newsstands.

We just found a planetary system that breaks the rules of the game with a planet where it should not be

by

The universe has a curious habit: every time we think we have a perfect standard model for how things form, something comes along that forces us to rewrite the textbooks. At the moment, our solar system (like many others) seems to have a logical order with rocky planets like the Earth near the Sun and gas giants far away, but what just published the magazine Science It is the exception that confirms that the rules are meant to be broken. A new model. An international team, with strong Spanish participation from IEEC-CSIC and the IAChas discovered LHS 1903, a system 120 light years away which presents an “impossible” architecture according to traditional models: rocky, gaseous, gaseous and… rocky again. The importance of order. This study details the discovery of four exoplanets orbiting a red dwarf starwhich a priori does not seem anything out of the ordinary. But the focus is on how they are placed, as can be summarized in the following list: LHS 1903 b: an inner rocky planet. LHS 1903 c: a gaseous sub-Neptune. LHS 1903 d: another gaseous sub-Neptune. LHS 1903 e: an outer rocky planet. The normal thing in planetary formation is that the outer planets, when formed far from the heat of the star where ice and gas are abundant, accumulate enormous gaseous atmospheres like Jupiter or Neptune. This is why a rocky, bare planet, without a gaseous envelope, in the outermost orbit is an anomaly that has baffled astronomers. It’s like there are two Earths in locations where they shouldn’t be. How it has been seen. To confirm this strange system, a single telescope was not enough. The finding is the result of the combination of data from TESSNASA’s exoplanet hunter, and the satellite’s surgical precision Cheops of the European Space Agency (ESA). In this way, while TESS detects the general transit signals when a planet passes in front of the star, Cheops is able to refine those observations to determine the exact size. Combining all this with velocity measurements from ground-based observatories such as the Canary Islands telescope, the team was able to calculate the densities and confirm that planet ‘e’ is indeed a solitary rock on the outside. How is it possible? A priori, there are two theories to explain why a planet loses its gas and becomes rocky: photoevaporation and the internal heat of the planet. However, neither of these theories work for LHS 1903 e. As the most distant planet, it receives much less radiation than its inner gaseous brethren and is too cold to have lost its atmosphere on its own. In this way, if the planet did not lose its atmosphere a priori, the only logical explanation that the authors find is that it never had it. The study proposes a training model in a gas-depleted environment where the protoplanetary disk ((the cloud of gas and dust where the planets are born) did not form all the bodies at once. What happened, theoretically speaking, is that the inner planets formed first when there was a lot of gas and the outer planet formed later. He is left with the crumbs. By the time the last planet finished forming, the gas in the disk had already dissipated or been absorbed by its older brothers. In this way, it was formed from solid “leftovers”, with no gas available to build an atmosphere. This supports the theory of the “inside-out” formation, where the planets appear sequentially. It is a scenario that has rarely been confirmed with such observational clarity as until now in this system. Its importance. This discovery forces us to rethink the history of solar systems around red dwarfs, which are the most common stars in our galaxy. And we even thought that the position of a planet determined its destiny, but LHS 1903 teaches us that timing is just as important. The LHS 1903 system thus becomes a perfect laboratory: four planets, the same star, but completely different birth stories coexisting in a stable orbital balance.

Netflix spends 17 billion on producing content and YouTube does it for free. And that’s why YouTube is winning the game

by

Alphabet first revealed in its Q4 2025 earnings report that YouTube generated more than 60 billion dollars over the past year, adding advertising revenue and subscriptions. The figure is 33% higher than the 45,000 million that Netflix reached in the same period and places the video platform above all the entertainment giants except Disney, which had a turnover of 95.7 billion. The data confirms what many in the industry already sensed: YouTube is not simply another competitor in the online video market, but the main beneficiary of the transformation in audiovisual consumption habits. Paradigm shift. YouTube’s victory reflects a profound transformation in how we consume video. While subscription platforms opted for the Netflix model (closed catalogs of professional productions), YouTube added in July 2025 13.4% of total television viewing time in the United States. It expanded its lead over Disney (9.4%) to establish the largest difference recorded since these measurements began. Youtube on your TV. Time spent watching YouTube on television has grown 53% since February 2023. The traditional streaming market, meanwhile, is going through what is known as “subscription fatigue“: the average number of subscriptions per consumer in the European market has stagnated at 2.35 in both 2023 and 2024, after growing systematically for years. This saturation has caused structural changes: the number of original series released in the United States fell 11% in 2025third consecutive year of declines from the 2022 peak. The difference in the plan. Breaking down where the money comes from can point to the reasons for this triumph. Of the 60,000 million in YouTube revenue, we have: Advertising revenue in the last quarter of the year was 11.38 billion dollars, with a growth of 8.7% year-on-year 325 million paid subscriptions on all your consumer services, such as YouTube Music or YouTube Premium For its part, Netflix: It reported revenue of $12.05 billion in the fourth quarter of 2025, with a growth of 17.6% For the year as a whole, the platform reached $45.2 billion, with more than 325 million paid memberships The most notable difference lies in the business model. While YouTube maintains a hybrid model where advertising remains dominant, Netflix revealed its advertising figures for the first time: in 2025, its third year selling ads, advertising revenue exceeded $1.5 billion, multiplying by more than 2.5 compared to 2024. The company projects double that ad revenue in 2026. Why YouTube wins. YouTube’s competitive advantage lies in features that traditional platforms cannot replicate. On the one hand, the radical democratization of content creation: Netflix invests 17 billion dollars annually to produce, while on YouTube the creators assume the production costs. The base of 69 million creators generates a volume of content that is impossible to match: every minute 500 hours of video are uploaded to the platform The second differentiating factor is the algorithmic recommendation system. YouTube’s recommendation system uses large-scale language models that can handle massive amounts of data. This allows YouTube to do something that closed catalog platforms cannot: recommend videos based not only on general categories, but by fine-tuning suggestions based on specific interests. In 2025, YouTube’s recommendation system is the most sophisticated and user-focused. The third advantage is the absence of entry barriers for the public. While Netflix requires a mandatory subscription, YouTube offers free ad-supported access, with premium subscription as an option. This hybrid model maximizes potential reach: YouTube’s monthly active user base reached approximately 2.7 billion people in early 2025. This means that more than 25% of the world’s population uses YouTube in any given month. What it points to. YouTube’s triumph over Netflix in annual revenue represents more than a change in leadership: it signals a structural transformation in how audiovisual content is produced, distributed and monetized. The centralized studio model, a direct heir to the Hollywood system, is giving way to a decentralized ecosystem where millions of creators generate content for hyper-segmented audiences. And the implications for the industry are very profound. Header | Photo of NordWood Themes in Unsplash In Xataka | A YouTube video that lasts 140 years has gone viral. Nobody is clear why

Tesla turns on the mega-refinery in Texas with which it wants to break China’s game

by

The map of global power is no longer drawn only with oil wellsbut with the critical mineral pathways. In a move that redefines the auto industry and energy geopolitics, Tesla has announced that its lithium refinery in Texas is already an operational reality. It is not just another factory; It is the West’s first major attempt to wrest the keys to 21st century mobility from China. The advertisement. tesla sent a strong message through its official channels: its lithium refinery is now operational. According to Elon Musk himselfthis milestone “marks the beginning of energy independence for North America.” The facility, located in Robstown, near Corpus Christi Harbornot only seeks to ensure the supply of components, but also to reduce logistics emissions and generate regionalized employment. As detailed by Spectrum Newsthe plant has met the ambitious deadlines set since it was launched the first stone in May 2023. What was then a project of more than 1,000 million dollars, today is, according to Musk’s wordsthe largest and most advanced facility of its kind on the continent. A look towards China. To understand the magnitude of this step, you have to look at the Asian giant. Tesla is replicating the successful strategy of the Chinese giant BYD: absolute vertical integration. It’s no longer just about designing software or assembling chassis; it’s about controlling the entire value chainfrom when the mineral comes out of the ground until it becomes a battery cell. The capacity of this plant is massive. According to the specialized media DiscoverAlertthe refinery has a capacity of 50 GWh per year, which translates into enough lithium to manufacture approximately one million battery packs per year. By eliminating intermediaries, Tesla not only ensures its production rate, but also shields itself from the frailties of global logistics and geopolitical tensions. Texas alchemy. The real revolution of this plant is not only its size, but its chemistry. As Jason Bevan explainsmanager of Tesla, the plant uses a pioneering process in the United States: alkaline leaching to directly convert spodumene mineral into lithium hydroxide suitable for batteries. Unlike traditional refining—which often relies on aggressive acids and generates hazardous waste such as sodium sulfate—Tesla’s method is acid-free (acid free). As the refinery staff explains in the official video released by the brandthis process eliminates toxic byproducts. Instead, it generates a mixture of sand and limestone known as “anhydrite.” This byproduct, far from being waste, is being integrated into the circular economy. tesla confirmed from the beginning of the project that this material would be used in the production of construction materials (concrete), turning a traditional waste stream into a useful resource. Is it possible to break away from China’s shadow? Despite the optimism in Texas, the reality of the global market remains overwhelmingly favorable to Asia. How we have developed in XatakaChina currently controls the refining of 19 of the 20 strategic minerals evaluated by the International Energy Agency (IEA). Their dominance is almost total, since they process 95% of the graphite and 98% of the rare earths on the planet. Furthermore, the Chinese advantage is not coincidental, but the result of decades of investment under the “Made in China 2025” plan. While Tesla has managed to build its refinery in a record time of 19 months, the IEA warns that, on average, a mine takes up to 17 years to be operational. However, the United States has begun to play its cards with unprecedented aggressiveness. According to OilPricethe US administration has moved from traditional lending to direct involvement, acquiring stakes in mining companies such as Lithium Americas. This paradigm shift seeks to close the gap with China through public-private collaboration that includes massive projects such as Thacker Pass in Nevada, which is expected to be the largest lithium supply in the Western Hemisphere by 2027. The mining ecosystem: from Nevada to Texas. Until now, lithium production in the United States was almost negligible. According to a CNBC report, the Silver Peak plant in Nevada, owned by Albemarle, has been the only active source in the country for decades. Their method, based on solar evaporation in giant pools covering 13,000 acres, is a slow process that requires 18 to 24 months to concentrate the mineral. The arrival of Tesla and other players such as American Lithium (which recently expanded its assets in Nevada according to their own corporate statements) is transforming the sector. While Albemarle focuses in the extraction of underground brinesTesla focuses on the refining of hard rock (spodumene), creating a diversified ecosystem that seeks to feed the growing demand for electric vehicles. A change of era. The success of the Texas refinery will not be measured only by the tons of lithium hydroxide it produces, but by its ability to demonstrate that the West can compete on costs and sustainability without depending on Chinese infrastructure. Tesla isn’t just making electric cars; is building the foundations of industrial sovereignty. This project is the first concrete step to reduce a dependency that until recently was considered inevitable. Time will tell if 19 months of Texan engineering can beat two decades of Chinese strategy, but, for now, Tesla already has one of the keys.

Today’s Barcelona game, the African Cup final and more on Movistar Plus for 9.99 euros per month. And without permanence

by

Being able to watch all the football in Spain it’s not cheap at all. Those of us who are soccer fans and like to watch games every week (whether our favorite team is playing or not) have a very interesting alternative that has a much more attractive price. We refer to Movistar Plus+a streaming platform that costs 9.99 euros per month (or 99.90 euros per year). And be careful: because it includes much more than the beautiful sport. Monthly subscription to Movistar Plus+ The price could vary. We earn commission from these links Movistar Plus+ comes with a lot of football this January It is a quite attractive price if we take into account everything it offers. Before that is what we will be able to see in the coming weeks, it is worth noting that it is a platform that we can hire regardless of the operator we are, so we will not have to change companies for it. Besides, has no permanenceso we can try it for a month and if it doesn’t convince us, unsubscribe in a couple of minutes. Let’s assume that we subscribe today, January 15. In that case, the first thing we are going to be able to see is the Copa del Rey round of 16 match against the Racing de Santander and Barcelonarecent champion of the Spanish Super Cup.

Nvidia is the ball in the AI ​​game. The US wants to share it with China, but it is not clear that China wants to play

The CES held in Las Vegas is the great showcase of technology, and if there has been a protagonist (apart from the chinese humanoid robots), that has been Jensen Huang. The CEO of Nvidia has become a key figure in the technology landscape. artificial intelligence because it is their chips that are shaping the data centersand the H200 It is the great proper name. It is the favorite for ‘assembling’ data centers and has become a throwing weapon in the commercial and technological warwith the United States vetoing the sale of the chip to China. But the situation seems to have relaxed and there are already those who point out that Nvidia will soon have access to a critical market. In short. We already mentioned it in December: Nvidia planned to increase production of the H200 chip for 2026. It was not something that responded only to the rise of artificial intelligence this year (which so many problems it is going to give us consumers), but to something much more important for the company: the reopening of the Chinese market. It all came after the announcement that the United States would allow exports, specifically, of the H200 to certain Chinese customers. They had to have a series of characteristics, such as being validated by the Department of Commerce, in addition to having a 25% rate on each sale. It’s outrageous, but while it was being debated whether China would now want to buy the H200s for its data centers (the country is developing its own solutions), from Reuters point to one piece of information: two million orders. Two million H200. After opening the door, it was reported that two Chinese giants such as Alibaba (e-commerce, cloud services and the model qwen) or ByteDance (TikTok, Douyin and AI chatbots) would be asking the Chinese Government to They will let them buy Nvidia chips to boost business. More recently, since Reuters A specific figure is pointed out: two million H200 chips (with ByteDance and Alibaba asking for 200,000 H200 each). It is the order that the Chinese companies would have already made, at the expense of receiving the green light to be able to formalize the purchase. Strict payment plan. The H200 is not the most cutting-edge chip that Nvidia has to offer, but it is one of the most used in data centers and the one that is allowed to export to China. Other more powerful ones remain restricted for national security reasons. And, although there is nothing official yet, Nvidia has set certain purchase conditions. Basically, transfer financial risk to customers: if imports are approved, they will have to make full payment in advance. Deposits were previously allowed to some companies, but this lack of regulatory clarity, market instability and a stock of H200 that may be insufficient if the market reopens require these measures. 50 billion dollars. With this operation, Nvidia must be crazy about music. In the middle of last year, Huang himself pointed out that the Chinese AI market had headed toward $50 billion, stating that “it would be a tremendous loss not to be able to address it as an American company.” That someone else says it may not have as much weight, but Nvidia is now in the focus of all the big technology companies. You don’t have to be naive. Messages like “the world is hungry for AI, let’s put American AI at the forefront” surely contributed to the relaxation of trade conditions approved by the Trump Administration a few weeks ago. In fact, if we say that Huang has been one of the great protagonists of the CES, it is not so much because of the technology presentation, but because of continuing to push that commercial narrative. The CEO pointed out in the ‘No Priors’ podcast that “the idea of ​​decoupling from China for philosophical or national security reasons is not based on common sense”, also stating that he was optimistic about the relaunched relationship with China thanks to the new measures imposed by the United States. Because “China is an adversary, but also a partner. And the idea of ​​decoupling is naive,” he said. What if I don’t want to now? But although Nvidia has increased production of its H200s in Taiwan in anticipation of an avalanche of orders from China, the ball is not in its court: it is in that of its potentially large new customer. Although everything boils down to “business,” in this case there is something else at stake: technological sovereignty. Huang believes that there will be no official announcement from China about the “openness” of its hand when it comes to letting its companies buy American technology and assumes that if orders are being placed it is because they can. Now, with the intensification of trade bans by the United States, China responded. Banned Apple devices in official centers, also purchasing from companies like Micron (which have also focused on AI, abandoning the RAM segment for users) and restricted the purchase of Nvidia chips Manufactured expressly for the Chinese market. At that time, Local companies such as Huawei or Cambricon have advanced with their solutionsachieving very high yields that are allowing China’s robotics and AI industry flourishes. Friction. However, the H200 remains the “standard” for many data centers, and there may be a desire to buy as much as possible in advance of possible future bans while they continue to develop their own chips. We will see if the wish of the American giant and some Chinese companies that see CUDA as the optimal system for AI. China is very clear that its “dragons” are enough to stand up to Western technology, the ‘Delete America’ plan is still going and accepting the H200 could perpetuate a situation of dependence on foreign technologysomething that the Government wants to avoid at all costs. In whatever way, depending on BloombergNvidia will start shipping H200 en masse in the short term. Images | Nvidia, Karola G, Pexels In Xataka | … Read more
