train

Mexico has made an extremely ambitious bet on the Mayan Train. And now a judge has suspended her

by

“It is a magnum opus, we are not exaggerating if we say that there is no one like it in the world today.” The phrase It was pronounced at the end of 2023 by former Mexican president Manuel López Obrador, and although in politics (no matter the nation) the use of superlatives is common, the truth is that it was not misguided. What López Obrador was referring to was the Mayan Trainan ambitious railway circuit of more than 1,500 kilometers that started more than two years ago between Campeche and Cancun and continues to take shape become a priority of the Government. Mexico needs it to be a success, but not at any price. What has happened? That the Mexican justice system has just reminded the country’s administration that, no matter how important and strategic it may be, the Mayan Train cannot advance with its back to the regulations. That is why it has issued a suspension order that will mark the works of one of its most controversial sections. For the project to continue advancing, from now on the authorities will have to put more effort into protecting natural resources in one of the most sensitive areas through which the railway must circulate: the region located between Cancún and Tulum, right where it passes. Section 5 of the Mayan Train. What has justice done? Dictate a final suspension order focused on that specific section. That does not mean that it has condemned the project or that the Mayan Train should give up its Cancún-Tulum stretch, although it does represent a wake-up call for those responsible for the project and a reminder that the work must advance while respecting its environment. Basically what the magistrate has done is demand that the environmental authorities of Mexico confirm that the project complies with the regulations and are responsible for monitoring it. The court order obliges the Federal Environmental Protection Agency (Profepa) to carry out direct and permanent inspections in the Cancún-Tulum section. No revisions on paper or reports signed from the offices in Mexico City, miles from where the works are being carried out. The ruling was issued thanks to the mediation of the organization ‘Save me’ and is addressed to Profepa and the General Directorate of Crimes, Commutations, Complaints and Complaints. Is it so important? Yes. According to precise The Chroniclerthe order places several duties on the competent agencies that, in practice, will force them to reinforce their surveillance. To begin with, they will have to carry out direct, field supervision of the project. They must also verify the effects on protected species, the protection of cenotes and control underground rivers. Finally, the ruling points out the need to prepare detailed reports. If these demands are not met, those responsible could face sanctions. What do environmentalists say? Sélvame has valued the judge’s decision as “a significant achievement” in the defense of the media. “It is an important step towards the protection of natural resources and guarantees that verification, inspection, conservation and protection actions will be carried out in the event of pertinent public complaints,” celebrate. The groups that have been warning for some time about alleged irregularities, such as tree felling or unsupervised work that affects wetlands, they advance that they will be attentive so that the order is carried out. What area does it affect? That is one of the keys. The Mayan Train is a wide railway circuit, more than 1,500 kmbut the focus has been placed on a very specific point: Section 5, which is in turn divided into various segments (north and south) between Tulum and Cancun. In total, according to the Mayan Train Guidemeasures just over 100 km. Beyond its length, shorter than other sections, the local press stands out which is one of the most sensitive. The reason: the presence of vulnerable ecosystems, caves and underground rivers and the threat to their biodiversity. In August 2024 the Verified platform assured that the construction of the Mayan Train had affected approximately 7.3 million trees, a good part (3.5 million) in Section 5. In 2024 A court has already ordered work to stop until geological, geophysical and hydrological studies are delivered. Why is it important? To begin with and as López Obrador himself recognized in December 2023, when he presided over the inaugural tour of the Mayan Train, because the railway circuit is not just any project. And not only because of its impact on the environment, its dimensions, its costs or enormous ambition. With it, the Mexican authorities aspire to promote the development of the southeastern region, articulating a new communications backbone that favors tourism. The problem is that its implementation is not being easy. Its premiere has not had the expected success (at least in passenger traffic) and its management has just change handsmoving to the Secretary of Defense.

Anthropic wanted to secretly scan and then destroy millions of books to train its AI. It hasn’t been so secret

by

A language model for AI needs input if it is to be trained to be more accurate and effective. The issue is how the information is obtained and whether there is an ethical way to do it that is profitable for the technology company in power. There is no doubt that the preferred option for companies has been to use all possible physical and digital content without anyone’s permission. There is also evidence. A judicial leak reveals that Anthropic invested tens of millions of dollars in acquiring and digitizing literary works without permission from the authors. According to account Washington Post, the project, internally called “Panama”, was part of a frenetic race among big technology companies to accumulate massive data to train their artificial intelligence models. How it all started. The Panama Project was launched by Anthropic in early 2024. According to internal documents revealed per the Washington Post, the goal was to “destructively scan every book in the world.” Furthermore, these documents also explicitly state that the company did not want anyone to know that they were working on it. In about a year, the company spent tens of millions of dollars buying millions of books, cutting their spines with hydraulic machines and scanning their pages to feed the AI ​​models that power Claudeits star chatbot. According to the media, the books, once digitized, ended up being recycled. Because has come to light. The details of the project have been revealed in a lawsuit for infringement of rights copyright filed by literary authors against Anthropic. Although the company agreed to pay $1.5 billion to close the case in August 2025, a district judge decided to make more than 4,000 pages of internal documents public last week, exposing the entire operation. They are not the only ones. Court documents reveal that other technology companies such as Meta, Google and OpenAI had also participated in this race to obtain massive information to train their models. According to revealed According to the documents, an Anthropic co-founder theorized in January 2023 that training AI models with books could teach them “how to write well” instead of imitating “low-quality internet slang.” On the other hand, an internal Meta email from 2024 described access to a digital library of books as “essential” to be competitive with rivals in the race to dominate AI. However, the documents revealed by the media also show how Meta employees expressed concern on several occasions about the legality of downloading millions of books without permission. An internal email from December 2023 indicates that the practice had been approved after being “escalated to MZ,” apparently referring to CEO Mark Zuckerberg. According to court records to which the media has had access, the companies did not consider it “practical” to obtain direct permission from publishers and authors. Instead, they found ways to mass-acquire books without the writers’ knowledge, including downloading unauthorized copies from third-party sites. Chat logs from April 2024 show an employee asking why they were using servers rented from Amazon to download torrents instead of Facebook’s own. The answer: “Avoid the risk of tracing” the activity back to the company. Data torrent. The documents to which the Washington Post has had access also they test that Ben Mann, co-founder of Anthropic, personally downloaded over 11 days in June 2021 a collection of books from LibGen, a gigantic library of copyrighted content. The outlet further revealed that, a year later, in July 2022, Mann celebrated the launch of the ‘Pirate Library Mirror’ website, which boasts a massive database of books and openly claims to violate copyright laws. “Just in time!!!” Mann wrote to other Anthropic employees, according to the outlet. Anthropic stated in legal documents that it never trained a revenue-generating business model using LibGen data nor did it use Pirate Library Mirror to train any full model. Anthropic’s legal solution. According to point the medium in its article, faced with the legal risk, Anthropic changed its strategy. The company hired Tom Turvey, a Silicon Valley veteran who had helped create the project Google Books two decades earlier. Under his direction, Anthropic considered purchasing books from libraries or secondhand bookstores, including New York’s iconic Strand bookstore. The company ultimately ended up buying millions of books and stacking them in a giant warehouse, often in batches of tens of thousands, according to court filings. The Washington Post assures In addition, the company worked with used book sellers in the United Kingdom. A project proposal mentions that Anthropic sought to “convert between 500,000 and two million books in a six-month period.” What the law says. Most legal cases against AI companies are still ongoing, but the media mention two court rulings that have considered that the use of books to train AI models without permission from the author or publisher may be legal under the “fair use” doctrine of copyright. In June 2025, District Judge William Alsup determined that Anthropic had the right to use books to train AI models because they process them in a “transformative” way. He compared the process to teachers “teaching schoolchildren to write well.” That same month, Judge Vince Chhabria ruled in the Meta case that the authors had not shown that the company’s AI models could harm the sales of their books. In the Anthropic case, the physical book scanning project was considered legal, but the judge determined that the company may have infringed copyright by downloading millions of books without authorization before launching Project Panama. The final agreement. Instead of facing a trial, Anthropic agreed to pay $1.5 billion to publishers and authors without admitting guilt. According to point According to the media, authors whose books were downloaded can claim their share of the settlement, estimated at about $3,000 per title.

Mexico needs the Mayan Train to work. And they are so desperate that they have put it in military hands

by

There are many ambitious trains, but like the Mayan Train there are not as many. And it’s not because this train stands out for its speedby go through impossible tunnels either for luxurybut because few trains in the world must support a load as heavy as this one: being the backbone of the tourism in Mexico. Born with tremendous ambition, he started his engines with promises of wealth. AND is crashing resoundingly. So much so that Mexico has completed the transfer of control of the train to the Secretariat of National Defense. Army, to manage. FONATUR Tren Maya was the organization attached to the Ministry of Tourism that, since 2018was responsible for leading and managing the project. However, things did not work out, the plans were not fulfilled and, already in September 2023, when Obrador saw the arrival of the deadline to launch the train, he began to take steps for the Secretariat of National Defense to take control. After a series of steps, and as we read in Chroniclerit was at the end of 2025 when the process was finalized for Tourism to stop operating the train and Defense to take charge of it. Goals. The program has the following goals: Consolidate responsible transportation with the environment and society. Offer a safe and innovative transportation system. Ensure profitability through efficient management. That last point sounds like an ax to the previous management, but they are going to have a difficult time. Indifference. It was a few weeks ago when, in an article published by El País, the figure was revealed: the Mayan Train moved 5% of the expected demand. Neither tourists nor locals seem to have the slightest interest in a vehicle that was born to unite the different regions of the Yucatan Peninsula. Just because, It is the tourist jewel of Mexicobut also a tremendously unequal region in which Chichén Itzá brings together the majority of archaeological tourism, to the detriment of the others. And it seems that the train is not solving this. The report states that, during the first year, it transported about 3,200 passengers daily. Do we contextualize? The forecasts were for 74,000 passengers per day. Billionaire failure. It is a hard blow for a project that was already born on the wrong foot. It was the most ambitious project of the previous president, Andrés Manuel López Obrador, one without private or foreign capital, 100% Mexican, which caused headaches practically from the beginning. Obrador took advantage of that public investment, but from an initial budget My dear between 120,000 and 150,000 million Mexican pesos -about 7,400 million euros-, it ended up costing more than 500,000 million pesos -about 24,500 million euros- for 1,500 kilometers of roads. Current itinerary Expansion. The change in management is not symbolic: a series of actions have been proposed to expand services. On the one hand, passing under military control implies that seeks to operate with greater security for passengers, especially in areas where conflicts with drug traffickers are a problem. Greater professionalization of management is also sought through an administration under military command, but in the background there is an expansion plan. The aim is to transport cargo such as food for isolated indigenous communities or medical goods. Also that the train serves as a humanitarian corridor in the face of misfortunes, and for this they will create more than 3,000 additional kilometerswith an extension to Puerto Progreso. Will anything change? It’s the million dollar question. On the one hand, the Sheinbaum Government has made it clear on more than one occasion that they want the railway to be the backbone of the country not only for the transportation of people, but also as a freight corridor. The goal By 2030, four million passengers per year and 4.7 million goods per year will be moved thanks to the integration with the Interoceanic Corridor of the Isthmus of Thuantepec. Come on, turn the train into something that can compete against the Panama Canal. But of course, it can become a way to move goods, but we have to see if passengers use it to move. In statements to El País, it is more profitable for locals, and it is also more practical, to get around by bus. And tourists usually arrive in Yucatán with already established itineraries that do not require train services. And, on the other hand, there are the controversies associated with the military and the construction sections that they were in charge of in the past. Sections 5, 6 and 7 were commissioned directly to SEDENA, and there are not few cases of environmental violations, social conflictsviolation of human rights against indigenous Mayan communities and extra costs associated with those sections under military control.

If your Madrid-Barcelona train now takes five hours, Renfe and Iryo have a message: there is no compensation

by

What used to be two and a half hours has become recurring trips of more than four hours. The Madrid-Barcelona line lives between speed limitations that are multiplying travel times. Adif is working hard to correct the alleged defects on the road. And, in the middle, some passengers who bought a ticket that promised a 150-minute trip that is now impossible to fulfill and who are not going to receive a single euro in compensation. The Madrid-Barcelona line. Since the occurrence of fateful train accident in Adamuz (Córdoba)the Madrid-Barcelona line is in focus. After months of complaints from train drivers, and self-imposed speed limitations, as they have confirmed to XatakaAdif strives to review all avenues to verify that there are no defects or, if there are, fix them. The company in charge of managing and maintaining the roads began applying temporary speed restrictions in the most controversial sections. These limitations they rose and applied punctually in the days following the Andalusian accident, with the vibrations being the focus of controversy. More, many more. As the days go by, the controversy has grown. To the reviews of Adif facilities a storm has joined which has complicated the service even more. The result: trains that were supposed to take 150 minutes between Madrid and Barcelona have been arriving regularly after four and a half hours. The latest news is that Adif has asked Renfe, Ouigo and Iryo to eliminate the last services of each day in order to be able to work for a greater number of hours and reduce the planned days of track inspection. These works will study the complaints reported by the train drivers and, if necessary, fix the damage on the tracks if the technicians consider that intervention is necessary, they point out in The World. No compensation. These warnings from the train drivers and the subsequent reviews by Adif are what are causing the continuous delays in the journeys. Delays that, however, will not be compensated by Renfe and Iryo, companies that already report on their websites that this situation does not fall within the reasons for returning a ticket partially or in its entirety. So much Renfe as Iryo They emphasize that these delays are unrelated to the service provided by the operators and, therefore, will not be reimbursed. In the case of the Italian company, this decision affects tickets purchased after January 28, while in the case of Renfe it will not be a reason for refunds for tickets purchased after January 31. An exception. What travelers from these companies do have the right to be relocated to another shift by the operator if their trains have been canceled as a result of Adif’s latest request. In the case of Renfe, which has issued its decision in statements that it has collected The Countrythe trains to relocate those affected will be of double composition to double the number of seats and the possibility of canceling the trip has been opened at no cost to the traveler. A new controversy. These delays and the decision not to compensate travelers, understanding that they are due to reasons unrelated to their services, deepen the controversies that have been surrounding railway compensation for months. And Renfe, by order of Congresshas the obligation to compensate again for delays of more than 15 minutes and return the money if the train arrives 30 minutes above the scheduled time. These deadlines were extended to 60 and 90 minutes respectively. in 2024 and They should have returned to their original deadlines in 2026 but this has not happened yet.

China urgently needed a train station, so it was built in nine hours with 1,500 workers and 23 excavators.

by

Anyone who has done a work at home will have already experienced firsthand that they know when it starts but not when it ends, something that happens in domestic works and that we also see from time to time with public works. And large infrastructures take time, although we have seen real records such as this 10-story building in just 29 hours. Of course, in China. Precisely there, in the city of Longyan in the southeast of the country, is where they have made a train station overnight. Literal. And although the work is a milestone in 2026, the reality is that this reform in record time took place in January 2018 and that left Elon Musk with his mouth openwhich had no qualms in stating that “China’s progress in advanced infrastructure is more than 100 times faster than that of the United States.” As China Central Television narratedat 6:05 p.m. the station closed and only 17 minutes later the remodeling kicked off in an action that more than a construction seems like a synchronized swimming number until 3:30 in the morning, the time of the end. A kind of “open heart operation” in public works Only nine hours for a project that, although it is true that it was not a new station from scratch, was not exactly small: it consisted of a remodeling and connection of roads between a new high-speed line between Longyan and Nanping and three existing railway lines. Furthermore, they decided to do it at night so as not to interrupt daily rail traffic. Because at 6:22 p.m., 1,500 workers grouped in seven units were executing seven different simultaneous tasks, such as Zhan Daosong tolddeputy manager of China Tiesiju Civil Engineering Group, China’s leading railway construction company. To carry it out, they relied on seven trains and 23 excavators. Thus, while one group installed monitoring and signage equipment, another paved the land. The millimeter precision and rapport is such that Reminiscent of open heart surgery but transferred to public works: with workers distributed over a range of 1.5 kilometers in their assigned places and 23 coordination teams to ensure compliance with deadlines and processes. Something like this is not done overnight, but before the day of truth They did six large-scale drills to prepare. The decision to do it at night has an explanation: not to interrupt the day’s rail traffic because in fact, at 1:56 in the morning they already had the first test train accessing the new station. Because they had also estimated a verification period of three and a half hours in which three other trains accessed the facilities. At 5:53 in the morning the rehearsals were over: K297, a normal passenger train, arrived at the station. As impressive as the speed of the project, which involves enormous planning work and prior studies, was the achievement achieved: reducing the travel time between both cities from seven hours to just an hour and a half thanks to the high-speed train that travels along the track at 200 km/h.

has just opened a school to train its future “explorers”

by

There was a time when talking about putting the Moon back on the calendar sounded like nostalgia, like distant echoes of another era. Today, that language has returned. The United States continues to push its return to the satelliteand China, meanwhile, is building its own path with an increasingly explicit ambitionalso in the human. In that context, the news is not just a new school in Beijing, but what it suggests: that space exploration is also becoming a talent problem. What exactly has been announced. The University of the Chinese Academy of Sciences (UCAS) just announced the creation of its Space Exploration School, defined as the first of its kind in China. It is not a space agency or a manned flight program, but rather an academic center oriented toward training and research. According to CGTN and CAS itself, the objective is to cultivate interdisciplinary professionals in fields such as interstellar propulsion, deep space communication and navigation, and space science, with a direct fit into large national projects. In detail. The school will offer an interdisciplinary curriculum that covers 14 fields, from aeronautics to planetary science, and will expand the current catalog with 22 new core subjects on a previous base of 97 courses. The idea is not only to add subjects, but to mix science, technology and real applications to form profiles capable of moving between theory and problem solving. Global Times points out an explicit objective: that students leave with a solid foundation in mathematics and physics, but with the ability to innovate and transform that innovation into engineering. Where and how. Students will have access to three major platforms and six training systems in Huairou Science Citywith examples ranging from simulation of unmanned space patrols to a circuit for developing end-to-end satellites and experimenting with collaborative space-ground innovation. New teaching platforms oriented towards internships and project work will also be launched, in an attempt to bring students closer to the mission logic. The admission. A double admission system is contemplated: choosing students already enrolled in the first year of the master’s degree and recruiting final year students for direct doctorate. In addition, a “dual mentor” scheme will be promoted with scientists and engineering managers, designed so that the student not only understands concepts, but also learns to convert them into solutions. This mix between research and engineering development is, in fact, one of the great promises of the project. “Explorers”, but not astronauts. The term attracts attention, and it is no coincidence that it appears repeated in the coverage. Now, we are not looking at a school to train crews, but rather to form scientific and technical profiles that make this leap possible, even for interstellar missions. They are asked to not only understand engineering to design vehicles or stations, but to have scientific literacy to investigate space science problems. The “explorer”, here, is the one who constructs and understands the exploration.

one dead and 37 injured after a train derailed in Gelida (Barcelona)

by

Just over 48 hours had passed since the Adamuz (Córdoba) railway accident occurred, the second most serious in our country, when Rodalies Catalunya reported a accident on line R4 between Sant Sadurní and Gelida (Barcelona). The train driver died in the accident and 37 people were injured. Five of them are seriously injured. What has happened? A retaining wall has fallen on the tracks of line R4 on the Rodalies line in Catalonia. The train has collided and has left the track. As a consequence of the impact and the subsequent derailment, Rodalies Catalunya has reported that a person has died. Click on the image to go to the original tweet The victims. As the company reported shortly before midnight, one person has died. This would be an active machinist or one of the two trainee machinists, they report in The Countryalthough it still has to be clarified. The emergency services have confirmed to the newspaper that 37 affected passengers have been treated. Five are in serious condition, six in less serious condition and 26 in mild condition. Most of them were traveling in the first car, which is the one that received the impact and most of the damage. Rodalies has set up a helpline for victims: 900 101 660. In addition to the emergency medical services, 70 members of the Fire Brigade had to go to the scene of the accident to rescue the people trapped inside the car and shore up the retaining wall to prevent it from continuing to fall. What is known about the accident. Rodalies line R4 connects Sant Vicenç de Calders – Manresa (through Vilafranca del Penedès). At that moment, a train traveling towards Manresa and between the stations of Sant Sadurní and Gelida (Barcelona) collides with a retaining wall that falls in its path, causing it to derail. At the moment, the causes that motivated the detachment are not known, but the first hypotheses point to the heavy rains that Catalonia has experienced in the last few days. Just yesterday, shortly before one in the afternoon, Rodalies reported a civil protection alert to coastal municipalities due to strong waves to prevent possible flooding. Derailment in Blanes. In addition to the Gelida accident (Barcelona) another Rodalies train has also derailed between the stations of Blanes and Maçanet (Girona), this time as a result of some rocks that have fallen onto the track. In this case there are no injuries to be regretted on a train in which only 10 people were traveling. The train axle broke in the crash. Click on the image to go to the original tweet Suspended service. There will be no Rodalies trains on today, January 21, 2026, and there is no estimated reopening date. The company has assured that the service remains suspended until all lines are reviewed and the safety of travelers can be guaranteed. It is estimated that the suspension of the service will affect an estimated number of between 350,000 and 400,000 passengers that move daily along the lines.

What can you do if your train has been cancelled?

by

Let’s tell you What are your alternatives if your train has been cancelled?now what are you going to have the right to. If after check if your train has been canceled or delayed If you are in for a bad surprise, you should know that there are European laws that cover your rights as a railway traveler. Therefore, what we are going to do in this article is explain to you in a simple way what all the alternatives you have are. This way, you can know your rights and decide how you prefer to act. What to do if your train is canceled He Regulation (EU) 2021/782 of the European Parliament and of the Council, of April 29, 2021which talks about the rights and obligations of railway passengers, covers what citizens can do when they have not been able to get on a train. This applies to when you arrive at your final destination more than 60 minutes late, which includes cancellations. The first thing is that you have right to money back what the ticket cost you. Of course, you have to request it within 30 days of cancellation. For claim the money from your ticketsyou should know that they will refund 50% of the price after 60 minutes of delay, and 100% after 90 minutes. The railway operators will also offer alternative transportation to reach your destination. In addition to continuing your trip, you also have the right to redirect your trip under similar conditions. The railway operator will have to pay you this if you do not want a refund, but rather reach the destination. They should allow you to take another train to make this journey in subsequent days, and even change the route of your trip in order to reach your destination. You can even choose an alternative means of transportation. You will also have right to meals and refreshments in a matter of how long you have to wait in the event of a delay. In the same way, if you have to spend the night The railway company would have to pay you for a hotel or other accommodation whenever physically possible, including transportation from station to accommodation and back. Here, in the event that there are massive cancellations due to some accident or major event, it is advisable that review the operators’ communications railway companies in the event that there is something additional that they add, or that at least speed up the claim processes or changes to your trips.

OpenAI’s obsession was to train its models like crazy. Now it’s run them faster than anyone else

by

OpenAI has signed an agreement estimated to be worth more than $10 billion with Cerebras Systems, a startup that designs advanced AI chips dedicated to one thing: running AI models as fast as possible. It is a unique alliance not only because of that change of focus, but because there is a conflict of interests. what has happened. The firm led by Sam Altman has committed to purchasing 750 MW of computing capacity over the next three years from Cerebras. Sources cited in The Wall Street Journal indicate that this alliance has an estimated value of more than $10 billion. We are therefore facing an operation extraordinary in size, but peculiar in form and substance. What Cerebras does. The firm based in Sunnyvale, California, was founded in 2015 by former engineers from SeaMicro, purchased in 2012 by AMD. The startup designs artificial intelligence chips specifically aimed at the inference stage of AI models, that is, executing them. More tokens per second please. When we use ChatGPT or any AI model, what we are looking at is an AI model using inference. Some “write” faster than others, and that speed of displaying text in responses is measured in tokens per second. Typically NVIDIA chips are great for the training phase, but not so much for the inference phase. Chips from companies like Cerebras —or those of the well-known Groqwhich has just been “bought” by NVIDIA—are precisely designed to run those models at full speed and obtain very high token per second speeds. The AI ​​is already good. Now she wants to be fast. NVIDIA’s recent “purchase” of Groq makes it clear that Jensen Huang’s company wanted the ability to offer those ultra-fast inference chips, and now OpenAI seems to want something very similar with its deal with Cerebras. AI models have already achieved remarkable performance in many scenarios, and although they are not perfect, now companies want them to not only work well, but also work very very fast and their responses, even if they are long, appear almost instantly. OpenAI wants more computing power. This operation also helps Sam Altman’s company with another objective: to obtain (and reserve) as much computing capacity as possible in anticipation of the fact that demand for these AI models will grow non-stop in the coming months and years. According to WSJ OpenAI already has more than 900 million weekly users, and its managers have frequently commented that they continue to have computing capacity problems. Brains grow. This agreement reinforces Cerebras’ position in a market that clearly demands this type of solutions. The firm is negotiating a $1 billion investment round that would bring its market valuation to $22 billion, tripling the current valuation, which is around $8.1 billion. In the past it has raised $1.8 billion according to PitchBook. Conflict of interest. This agreement also draws attention for an important aspect: Sam Altman, CEO of OpenAI, is also an investor in Cerebras (he is at the bottom of this Cerebras website) and indeed your company At one point he considered acquiring Cerebras although in the end that operation did not bear fruit. We are therefore faced with an operation that theoretically benefits Altman on both sides, which is worrying. How will OpenAI pay for this party? This new agreement once again triggers the debate about OpenAI’s ability to meet its credit and debt obligations. In 2025 it generated about 13,000 million dollars in income, but that enormous amount remains minuscule if we take into account that the contracts it signed with OracleMicrosoft or Amazon They amount to about 600,000 million dollars that will have to end up getting from somewhere. Where from? It’s a good question. We’ll see if they can end up answering it.

The real surprise of this “Chinese AI tiger” is the launch of GLM-Image…and not so much for what he does, but for how he has managed to do it. what has happened.

That’s interesting, but even more striking is the fact that the model has not been trained with conventional chips. Trained with Chinese chips. According to those responsible for Z.ai, this model is the first developed in China that has been fully trained with “local” chips. Specifically, it has been trained with Huawei’s Ascend chips thanks to the use of servers Huawei Ascend Atlas 800T A2 and a framework called MindSpore. Thus, traditional NVIDIA AI chips, which are usually the usual choice for AI model developers in Chinese startups, have not been used. Turning point? This milestone demonstrates the real feasibility of training high-performance generative AI models on a platform developed entirely in China. We are not dealing with something minor: it is validation that it is possible to continue innovating in this area despite the restrictions imposed by the US. In fact, Zhipu AI — included last year on the US blacklist — has intensified its collaboration with other local manufacturers, such as the promising firm Cambricon that has risen from the ashes thanks to tariffs. Threat to NVIDIA. The news comes at a unique time, because NVIDIA has not stopped pressuring the US government to once again allow it to sell its advanced AI chips to Chinese companies. He has obtained that permission—which It won’t be free—, but now the one that might not be interested is China, which he hasn’t said anything at all. That chips from companies like Huawei are a valid alternative for training quality AI models can change many things in this area. Zhipu goes like a shot. The Chinese startup has also just gone public, and since it has done so its shares they have shot up more than 80%. Investors see the company no longer as a rival to Google or OpenAI, but as a banner. One that shows that it is possible to compete without depending on the US and its companies. Huawei, great beneficiary. If the trend continues, Huawei can become the Chinese NVIDIA, and the company prepares an increase in production of its AI chips. It is not the only one: Cambricon plans triple your production by 2026, which seems to make it clear that the Chinese industrial machinery is moving quickly to neutralize the impact of US vetoes. Challenges…Despite everything, Zhipu already has warned that the price war in the AI ​​sector will become international. If Chinese companies end up controlling the entire chain (or rather, their chain), they could offer AI services at much lower costs than their Western competitors, who must pay NVIDIA’s margins and Big Tech’s cloud infrastructure. …and unknowns. This technological achievement raises other questions. One of the most important is how powerful and capable Huawei chips are compared to NVIDIA’s in these processes: is training much slower? Is it more expensive in time and resources? The efficiency of the MindSpore framework compared to Pytorch or TensorFlow is another of the key components of these developments.
