There will be a before and after Deepseek. We already know why this is so efficient

by

The publication of the V3 model of the artificial intelligence (AI) Deepseek as an open source is a blessing. And it is because little by little we are knowing in detail the strategy of the engineers of this Chinese company to Take a model of so efficient. Before moving forward with this article, it is important that we keep in mind that Depseek says that has trained his model using only 2,048 chips H800 of Nvidia. Some analysts defend that, in reality, its infrastructure brings together 50,000 GPU H100 Buy through intermediaries, but for the moment it is just a conjecture. This chip is more powerful than the H800, but it is perfectly credible that Depseek has been forced to settle for the latter because The sanctions of the US government They have prevented Chinese companies from access to the H100 GPU. In fact, since November 2023 Nvidia cannot deliver To your Chinese clients your H800 chip. One of Depseek’s keys is called PTX In the recipe for the thrilling growth that Nvidia has experienced during the last five years, its GPU does not intervene; CUDA technology (Compute Unified Device Architecture) also has An essential role in your business. Most of the AI ​​projects that are currently being developed are implemented on CUDA. This technology brings together the compiler and development tools used by programmers to develop their software for NVIDIA GPUs, and replace it with another option in the projects that are already underway it is a problem. Huawei, who aspires to an important portion From this market in China, it has Cann (Compute Architecture for Neural Networks), which is its alternative to CUDA, but for the moment CUDA dominates the market. In addition, this Nvidia tool puts in the hands of programmers High level language that allows them to access the GPU hardware in an affordable way. Even so, and we reach the heart of this article, Deepseek engineers have not used Cuda to develop their AI: They have used PTX (PARALLEL THREAD EXECUTION). Deepseek engineers have decided to use PTX to get the most out of the H800 GPUs as possible This language is similar to the assembly. In fact, it is somehow the assembly that proposes the developers who use their GPUs and need to implement low level optimizations in their code. Programming with PTX is more difficult and laborious than doing it with CUDA, but it entails the advantage that it allows developers to write a more efficient code, and, therefore, capable of taking better advantage of the resources offered by the Hardware of the GPU. Presumably the Deepseek engineers have decided to use PTX to get the most out of the H800 GPUs they had in their possession. One of the stratagems they have devised has consisted of assigning only 20 SM (Multiprocessors streaming) From each GPU to the communication between the servers, which has allowed them Dedicate the remaining 112 From each chip to calculation processes. In essence, Deepseek has been built since zero by resorting to this type of optimizations, which largely explains why this AI model is so efficient. The programmers of this Chinese company have objectively materialized an achievement in the field of engineering that will in all likelihood will have a deep impact on the way in which AI models developers will face their projects in the future. This is the palpable evidence that China is successfully adapting to the shortage of GPUs that have triggered US sanctions in their companies.

Half of all the frozen semen produced by Spanish men comes out in a single city: Granada

by

Neither Madrid, nor Barcelona; Neither Valencia, nor Seville: the place in Spain where more semen is donated the most It is Granada. And it is by far margin: of the 56,700 donations of male gametes between 2018 and 2023, 23,096 were made in this province. Practically half. Is something that was already knownbut Ana Requena It has just updated the data And it’s really surprising. Because if the question is “What is happening in that city?” The answer is not only curious … it is very interesting. Granada, national semen champion. It is true that obtaining reliable data is complicated. Above all, because (although clinics and hospitals are obliged to turn their data in assisted human reproduction information system) we have not managed to have a centralized record. However, in this case the reliability is the least: we talk about such a brutal difference that we can give it for good. Granada is the queen of the semen of Spain and is something completely recognized in the sector. But … why? The person responsible for this has names and surnames: Ceifer Biobanco, a private semen bank that was founded in the city almost 30 years ago and is a national reference. In fact, he works with about 500 reproductive centers in the country. That is key. Because, as explained at Eldiario.es Juan José Espinósthe president of the Spanish Fertility Society (SEF), having an authorized center to collect semen is not easy: “In the same way that most assisted reproduction centers collect ovules, there are few authorized for semen of donors.” “There are more donors where more promotion is made and concentrated in places where there are specialized banks,” Espinós explained. So it is not because the Grenadians are extremely fond of this? Yes and no. As Juan Pablo Ramírez explained a few years agomanaging director of the company, although Donor’s profile has been changing over the years (and older men, workers and parents have been incorporated), “students continue to assume 80% of the total donations.” That is one of Ceifer’s keys: that Granada is the student city per hintomasia. A city of about 250,000 inhabitants that has a university of 80,000 students (and that is only a part of its training offer). But, without a doubt, it is a management success. After all, Ceifer also has venues in Seville and Córdoba, others of the two leading cities in donations. And it is not easy either. As they explainedonly 10% of those who are interested end up being accepted. To the age requirements (less than 50 years), we must add a personalized interview with a psychologist and a whole battery of medical tests that discard hereditary diseases and ensure the quality of the semen. So yes, Granada is at the top. And it seems that it will continue to be a long time. After all, the two cities that follow it from afar are also feuded by Ceifer. Who was going to tell us that the geopolitics of the semen was going to talk about the importance of having long -standing institutions attached to the field?

They are almost 6,500 million light years

by

We are accustomed, or almost, to listen that the James Webb space telescope (JWST) has discovered a new galaxy in the confines of the observable universe. However, it is not always necessary to go so far to appreciate the immense power of the orbital telescope. Just stay halfway. 40 new stars. An astronomer team with representation of the University of the Basque Country and the DIPC (Donostia International Physics Center) has managed to capture in images and identify 44 new stars. This is the greatest number of stars identified in the distant universe to date. In addition to the stars, the team also discovered what could be a distant supernova. To almost 6,500 million light years. What makes this singular finding (in addition to the bulky number of stars found) is in the distance of these stars: these are found 6,500 million light yearsspecifically in the dragon arch galaxy. The stars find at such a distance that we see them as they were when the known universe had approximately half of their age. This galaxy is behind an immense cluster of galaxies, called Abell 370. A new lens for the JWST. The presence of Abell 370 It was instrumental in the discovery of these stars. All due to the gravitational lens effect. The enormous mass of these galaxies distorts the space around it, which diverts the light similar to how the lenses of a telescope do. This allows James Webb to see objects furthest than in principle would allow their already wide capacities. This phenomenon is also responsible for the “arched” aspect of the galaxy in which the newly discovered stars are located. The dragon arch is a spiral galaxy whose image comes to us as if it were a gum, all due to the influence of Abell’s cluster 370. The color of the stars. In his analysis of these stars, the team responsible for his discovery paid special attention to these. They discovered that it is red supergigants (such as the giant Betelgeuse, visible in the constellation of Orion). According to Explain the teamthis contrasts with previous similar findings that had predominantly detected blue supergigants. The details of the study were published In an article In the magazine Nature Astronomy. A new way to unravel dark matter. Beyond the relevance of finding such distant stars, the team highlights that the finding can teach us new details about the cosmos. Specifically, help us to reveal the mystery involved in dark matter.

Germany was the great European automobile power. Now, more and more manufacturers are clear that it is the place to avoid

by

“Germany is the place where the car was invented.” This clear and forceful are shown in the Verbandes Der Automobilindustrie (VDA)the German automobile industry association. An organization that estimated that in 2023 they worked in this sector 779,700 employees throughout the country. To get an idea of ​​the size of the automobile industry in Germany, in 2023 they manufactured 4.1 million passenger vehicles and almost 200,000 commercial vehicles. In Spain, the second largest vehicle producer in Europe, we manufactured half a million commercial vehicles but we stayed at 1.9 million passenger cars, according to data collected by Expansion. In fact, Germany is also the first country in Europe and the second largest producer in the world of electric cars. In 2023 they manufactured 1.27 cars moved by this technology. It would be expected, therefore, that with this experience it would attract more and more interest of new companies that intend to settle in Europe. Nothing is further from reality. A gigantic problem However, Germany faces a huge restructuring problem in the automobile industry. Their companies are in a process of conversion to the electric vehicle that points to thousands of layoffs but, in addition, the new companies seem clear that Germany is already the place where not to mount their factories. The last to position has been controversial. Asked about a possible polestar factory in the country, Michael Lohsccheller, general director of Polestar, responded to the newspaper Welt that “Germany It is not precisely the cheapest place For car production. Everyone knows what the general conditions are at the moment. “ With that last sentence, Lohscheller referred to the loss of German competitiveness in the automobile industry. Stefan Bratzel del Center of Automotive Management (CAM) I pointed to DW This same month of January that the country suffered with “high labor costs, including medical care expenses and extensive holidays” of its workers. To that same medium, Dirk Dohse, of the Kiel Institute for the World Economy (IFW) made it clear that German engineers were still among the best in the world but that the lack of flexibility prevented them from attract new talentsespecially from Asia. The country has been in a Institutional and economic internal crisis which is being deeper in the automobile industry. This loss of competitiveness has led manufacturers to warn that There are 190,000 jobs at stake If the industry does not find a solution. An output that looks more and more complicated if you consider that its manufacturers are drawing much more exports performance to China of electric cars than of combustion vehicles. This is a problem because the latter can get much higher per yield per vehicle sold than to electricity but also have a much lower competition than in the electric car market where the customer is turning to the local product. With the pressures of European policies to hug the electric car, the industry has undertaken a conversion in its factories. However, until 2024 technology Keep growing at a paid in EuropOh In China they see the European car as a outdated product. The latter is especially important in a country that houses a huge labor force of Volkswagen, Mercedes or BMW, whose world sales volumes They are especially sensitive to Chinese purchases. With bad results, Volkswagen has tried to fire tens of thousands of employees In Germany but, above all, the country sees How are production of vehicles or batteries to places like Spain, with lower labor and energy costs. A good example is the plant of Volkswagen in Sagunto to nurture Ford and Martorell. But, in addition, Germany is not attracting new investments. Northvolt’s project in Germany did not go from the theory while Spain has received Catl’s support, Byd has settled in Hungary and Leapmotor already produces cars in Poland and, It is rumored, that in Spain. Besides, Morocco and Türkiye They press to show themselves as especially attractive countries to produce cars as cheap as possible.

OpenAi has taken everything he wanted from the Internet to train his AI. Now accuses Depseek of stealing his data

by

The models of AI of Deepseek They are really good. They show it comparative evidence we publish yesterday and that put it at the level of chatgpt, Claude or Gemini. That has unleashed praises, but also suspicion. There are people who do not believe that training deepseek It has cost just 5.6 million dollarsbut also now in Openai they accuse Depseek of something else. Deepseek, you are using our data without permission. Openai spokesmen have indicated Financial Times They have discovered evidence that “distillate” techniques have been used from OpenAi models used by Depseek. What is that of “distilled” in AI? Yesterday we talk about how Depseek developers have used a large number of techniques to achieve such an efficient model. Among them stands out for reinforcement learningbut it is also known that they use models distillate. In this technique a smaller “student model” is taught to behave as a larger and more advanced “teacher model”. Data of the “teacher model” are used so that the small model is faster and more efficient, but equally intelligent in specific tasks. Use not allowed. The distillate or distillation of models is a common practice in the industry, but the terms of OpenAi service prohibit that their models be used for this purpose. Thus, it is specified that users cannot “copy” none of their services or “use the output (of Openai models) to develop models that compete with Openai.” OpenAI and Microsoft have already investigated this. According to Bloombergboth companies analyzed last accounts that were being used to take advantage of their chatbots and that apparently belonged to Deepseek developers. They used Openai’s API, but there were suspicions that they had violated the terms of service by taking advantage of that access to make distillate of their models. Many do. David Sacks, responsible for AI in Donald Trump’s team, alerted him to what was happening and said there was evidence that Depseek had used OpenAi data. Spokesmen of the company led by Sam Altman indicated that “we know that companies of the People’s Republic of China – and others – are constantly trying to distill the models of leading companies in AI in the US.” The thief is believed that everyone is of his condition. The ironic thing here is that Openai has not had scruples when collecting internet data to train their models, also violating the terms of service of those platforms. Last year it was discovered for example how transcribed a million youtube hours To train GPT-4. Timnit Gebru, famous for his controversial dismissal From Google, I commented on LinkedIn that Openai “must be the most insufferable company in the world.” And he continued: “They can steal the entire world and swallow all possible resources. But no one can give them their own medicine not even a bit.” If you are on the Internet, it can be used, right? Other companies They do exactly the sameand are shielded in the argumetno of “fair use.” They collect Any public content On the Internet without asking users or permission or platforms. Not only that: it is suspected that in many cases these models are trained with works Protected by copyrightsomething that has resulted in numerous demands.

Mets launcher Dardo against Yankees fans: “They don’t understand baseball”

by

The 2025 major league season and the encounters between Mets and Yankees are more than evident have not yet begun. Proof of this were the explosive statements of the launcher Aj Minterwho signed for two seasons with those of Queens in exchange for $ 22 million. After taking the Dominican Juan Soto from the Yankees, the Mets took the lead in the market and the pique continued later that in statements extracted from Sny, MINTER talked about his experience with the fans of the mules. According to the reliever, Mets fans are the true ball followers. Otherwise Yankees public that according to him do not understand baseball. “It can be said that these Mets fans are true baseball fans. They understand baseball, not like those on the other side of the city”Miner said at his discretion. MINTER’s comment is founded that he has been able to face many teams but according to him there are no better fans than those of the Mets. “These are the true staunch fans and will be with you until the end. I had to face them all throughout my career and they always did the best of themselves, so we cannot wait to launch for you now, ”he added. The arrival of Minder to the Bullpen of the Mets serves as an experience reinforcement available to the manager Carlos Mendoza. The left -hander comes from a season with many injuries; Despite this, he launched in 34.1 innings, leaving 35 strikeouts and 2.62 percentage of clean races.
