The most powerful telescope in Europe has seen something rare while observing two brown dwarfs: a perpendicular planet

by

Today, in things that we did not know that there were in other star systems: a planet that orbits perpendicular to its two stars. It is as strange as it sounds. A different planet. We have seen everything in the exotic exoplanet gallery that the observable universe offers us, but a new surprise has forced astronomers to readjust their expectations. Using the Vary Large Telescope del Southern European Observatory (ESO) In Chile, astronomers have found the first exoplanet known in a polar orbit around a binary system of stars: two young brown dwarfs. Orbiting at 90 degrees. Baptized as 2m1510 (AB) B, this world has two Tatooine style soles, something extremely common when it comes to more massive stars, but not so much in the case of brown dwarfs. However, what is common is that orbits its two host stars in a way that until now had only theorized: turning perpendicular to them, in a polar orbit of 90 degrees. We sensed that they could exist. Astronomers had already detected planetary training discs in polar orbite and theory suggested that They could form stable planetsBut finding them was another story. 2M1510 (AB) B is the first credible test that this configuration exists. And the most curious thing is that the team was not actively looking for this type of planet, they found it while refining the orbital and physical parameters of the two brown dwarfs, seeing that the path of the two stars was being pushed and pull in unusual ways. It is not a usual system. The planet is not the only rare in this neighborhood, taking into account the host stars. Brown dwarfs are larger than giant giant planets, but too small to maintain nuclear fusion which characterizes the stars “really”. But the rarity does not end there. These brown dwarfs form an eclipsest binary, which means that from Earth we can see how they hide each other. 2M1510 (AB) is an incredibly infrequent system: the second pair of eclipsessing brown dwarfs known to date. With more than 5,800 exoplanets confirmed to date, only about 16 orbit around two stars. That one of them does precisely around a system as atypical as a binary of eclipsessing brown dwarfs, and with a polar orbit, it is a real cosmic jewel.

The most frequent gross salary in 2023 did not exceed 16,000 euros a year

by

Salaries have been in the center of the political news before a consumer market With upward prices and a Mermous purchasing power for inflation in recent years. The National Statistics Institute (INE) has published the consolidated data of the ‘Salary Structure Survey’of 2023 and leaves a worrying fact: the most frequent gross salary in Spain does not exceed 16,000 euros a year. Downward wages. According to the data obtained by the INE on a base of 220,000 workers surveyed, the most frequent salary in Spain In 2023 it was 15,574.9 euros gross per year, a figure that received 4.6% of the total employees. This data is especially striking because it is a considerable decrease compared to 2021, but an increase with respect to 2022 that was 14,586.44 euros. Between 2018 and 2020, the INE data placed the most frequent salary at 18,468.9 euros per year, which shows a clear setback in the most common retribution. The second most frequent remuneration is already at 19,500.29 euros gross per year, salary that recognizes 4% of workers. In addition, the statistic indicates that one in four employees (25.6%) charged between 14,000 and 20,000 euros per year in 2023. In contrast, only 10% of employees earned more than 49,836 euros gross that year, while three out of four had a gross salary of less than 34,992 euros per year. The INE emphasizes that “many more workers appear in low values ​​than in the highest salaries.” The SMI effect. The main reason that explains the downward difference in the most frequent salary from 2021 is the Progressive Increase of SMI. This increase has caused salaries to be drastically reduced by the SMI, which In 2023 he set in 15,120 euros per year, which meant an 8% increase compared to 2022. This climb has made many workers who previously charged that amount They have seen their salary increased Until that level, making salaries in the strip of less than 16,000 euros more frequent. The average salary improves a bit. The concentration in low salaries in the strip between 14,000 and 16,000 euros has also promoted the average annual salary per worker. In 2023 it increased by 4.1% compared to the previous year, standing at 28,049.9 euros. This increase is the tenth consecutive year of growth, although the average salary is still well above the most frequent salary and medium salary (which divides the number of workers into two equal parts) that reached 23,349 euros per year. Gender differences. The salary difference by gender remains evident in the labor market of Spain. The average annual gross salary of men was 30,372.49 euros, while that of women stood at 25,591.31 euros per year. Although the salary of women grew 5.1% compared to 3.4% of men, women continue to charge only 84.3% of the average male salary. However, this difference is not attributable to discrimination because of gender since “it is reduced if similar jobs are considered.” Actually, the difference is derived from the greatest incidence of Part -time work among women (21.1%) against men (6.6%), resulting in a lower annual salary. The salary goes by sectors. The data of 2023 have revealed that the sector with the greatest annual remuneration was that of supply of electricity, gas, steam and air conditioning, with an average salary of 54,447.9 euros. This leaves this labor sector between The best paid with almost double the national average. They are followed by financial and insurance activities, with 48,922.8 euros per year. At the opposite end, hospitality workers, who received 16,985.78 euros and those of other services with 19,751.59 euros, figures well below the averagealthough both sectors experienced increases compared to 2022. Rich community, poor community. In the breakdown for autonomous communities, the Basque Country leads the ranking with an average salary of 33,504.9 euros, followed by Madrid (32,219.6 euros) and Navarra (31,199.6 euros). This average denotes a labor market with a predominance of employment in banking, industrial, technological and added value services, which offers higher salaries and, therefore, raises the salary average of these communities. On the opposite side, Extremadura (23,684.2 euros), the Canary Islands (24,033.5 euros) and Castilla-La Mancha (24,885.6 euros) registered the lowest wages, regions in which the low wages of the hospitality and agricultural sector have reduced the average salary. However, all regions increased their average salaries in 2023, highlighting Extremadura (8%), Navarra (6.9%) and Murcia (6.2%). In Xataka | The average salary in Spain has grown up to 1,987 euros.

Here are all the degrees related to technology and science with their cutting notes

by

In just a few days the University Access TestAka the Pau. It is a very marked date for the more than 300,000 students who have been preparing for at least two years to face these exams. It is not for less. Pau marks the end of one stage and the beginning of another, one that means making the leap to the university world and prepare for the professional world. If, after considering the different options, you have decided that your future is to study a university degree, the same doubt arises that arose to many at the time: which one to choose. If you usually visit Xataka or you like what we are dealing with on this website, it is possible that You are interested in technology, science, engineering, space or health. Thus, we have filtered each and every grades of each and every one of the faculties and cities so that, at a glance, you can see the offer of degrees, where they are taught and its cut -off note. The degrees of degrees related to technology and its cuts of cuts That the following table with its 1,021 cells does not intimidate you. Using it is really easy. In the upper part you will see a search engine. In it you can introduce the name of the degree, such as “computer engineering”, “artificial intelligence”, “mathematics” or “biotechnology.” You can also search for a city. In any case, and choose the filter you choose, You can order the offer of degrees by cutting note. By default, order is from highest to minor. If you are looking for another degree or want to know other cutting notes, RTVE has a very useful search engine on its website. How you can check, the degree with the greatest cutting note is the double degree of physics and mathematics at the University of Seville: A 13,764. The lowest is the minimum to approve: a five. The offer of degrees that can be accessed with the minimum note is wide and includes endless engineering. In fact, the vast majority of engineering between five and eight on average, and the number of places is usually wide. And that is good news. According to the study “The employability of young people in Spain 2024” of the CYD Foundation on work outputs according to the university career, engineering (electrical, industrial electronics, software development, telecommunications, etc.) are those that offer better working conditions in terms of Stability in contractssalaries and affiliation rates. On the other hand, the Emerging jobs and sectors report 2024 highlights the Professional boom in AI. The demand for data engineers and Machine Learning has grown 625% since 2019, and that of artificial intelligence engineers an annual 83%, both with very low competence of candidates for offer. Last year they enrolled to do 341,831 students and 90.2% approved. That is, 295,250 students took a five or more. Another thing is the average note. In 2024, the average grade of those presented to the general and specific part (necessary to aspire to remove a note greater than ten points) was 7.05 nationwide. If we talk about the degrees contemplated in the upper table, The average note is 8.87 points.

I had no idea how to execute a local AI and I just did it in five minutes with my Android. It has been a disaster

by

The career of whom he manufactures The most capable smartphone It will not be alone in its components: AI has become an essential absolute To win this battle. Gemini He is the absolute protagonist, both in Android and in an iOS in which The presence of AI is insignificant. A complete and capable assistant, with the requirement of being permanently connected to the Internet. Google, Gemini’s mother, has decided Give 100% local models a chance in Android. Including those of its competitors. I, who had never executed a local AI on a PC, I have been able to achieve it on my phone in five minutes. 10 Google applications that could have triumphed Installing Google ai Edge Gallery Google has released an open source app so that any user can interact with multimodal AI models. It is completely free, has no publicity, and its only limitation is that it is not published in Google Play Store. You have to Download it from github. It is as easy as clicking on the link and downloading the file, which weighs 115 MB. Once you have downloaded it, click on it and install like any other app. Depending on the customization layer you use and the browser from which you download it, it is possible that the system asks for the occasional permission. Give it without fear, since it is a clean Google app. Once installed, the app will be in the application drawer or desktop of your phone, depending on your layer. Just open it and download the available models to start using it. Using the local AI in my Android This application allows you to use four predetermined models of the local AI: GEMMA-3N-E2B-IT-Int4 GEMMA-3N-E4B-IT-IN4 GEMMA3-1B-IT-Q4 Qwen2.5-1.5b-Instruct Q8 Each of these names is very likely to sound to Chinese, but there is a very simple summary. Gemma are the Google models, and the number behind “E2B, E4B, 1b”, refers to the parameter number of each model (2 billion, 4,000 million, 1,000 million). This means that, in order, Gemma 3 1b is the fastest, but more basic model, followed by E2B and with E4B to the head as the most complete. On the Qwen side, it is a Chinese model developed by Alibaba, with 1.5 billion parameters, and quite logical precision. These are the models that the app brings, but we can install models on our own. What I win and what I lose using the local The Google app is designed to execute three scenarios of use: Images questions: problem solving, identifying objects, etc. Prompt Lab for summaries, rewriting texts and code generation. Ai Chat: Multi -urnal conversations with AI The local AI is somewhat more limited in these scenarios of use, but in return it is more private. It runs 100% on your phone, without connection to servers. This minimizes response latency, something that I wanted to verify with a fairly simple test: the translation of a text not too extensive. “If the computing power on each chip continue to grow exponentially, Moore real Demanded Were Useful in Business Applications, Too. Defense Contractors Thought About Chips Mostly As a Product that Could Replace Older Electronics in All The Military Systems. “WHEN US DEFENSE SECRETARY ROBERT MCNAMARA REFORMED MILITARY PROCUREMENT TO CUT COSTS IN THE EARLY 1960S, CAUSING WHAT SUB IN THE ELECTRONICS INDUSTRY CALLED THE” MCNAMARA DEPRESSION, “FAIRCHILD’S VISION OF CHIPS FOR CIVILS SEEMED PRISON Off-The-Shelf Integrated Circuits for Civilian Customers Even Sold Products Below Manufacturing Cost, Hoping to convince more customers to trym. “ Chatgpt (4th): 5 seconds Deepseek: 19 seconds The local Google (Gemma 3 1b): has not understood the instruction. Google local (Gemma 3 E2b): 26 seconds. Google local (Gemma 3 E4b): 34 seconds. Google local (Qwen 2.5): 16 seconds. The results are quite irregularand that is that the app is in its initial stage. The main problem I have found is that sometimes it is difficult for him to execute the model, even in cases of light models such as Qwen. In a Samsung Galaxy S25 Ultra I had to restart the app on some occasion, since I did not execute the prompt. I have also wanted to prove how simple problems solve with the visual understanding of images, using the heavy model E4B of Gemma. It has also been quite disaster. In the first attempt I have asked him to solve all the problems. He has succeeded. In the second, I have asked him to solve only the first. He was wrong and, after telling him that it was wrong, he has err. Yes, he does a good job recognizing elements in the images, but it still has a hard time going further (Google just lets his Gemma models choose for these tasks). The conversational assistant works well, with its limitations, but well. It serves to talk and help us with any task that we can think of that you do not need a real -time search on the Internet. If you are especially jealous with your privacy, and want to execute the without any server connection, it is a relatively valid alternative. Google has this app as a test laboratory. At least for now it is not a real alternative, much less, to Gemini.

There is an influencer shining in all public baths in Spain so that others do not have to do it

by

Ali Blackbet is a unique case within content creators. His accounts in social networks, especially those of Tiktok, have ended up finding a unique niche, a space reserved for the largest: the testing of public toilets, which executes with a very personal and hilarious style. Her sense of humor and the sophisticated of her edition and locutions make her a real rarity … and an essential event if you are interested in humor in bad taste. Seven months in toilets. Ali Blackbet started with his Tiktok account in 2021 (or at least, the historic takes us there), but had been on Instagram since 2012. Until last year, its contents focused on what was clearly interested: Disclosure on occultism and dark historytypical entrances of Diario everyday influencer and a multitude of Concert images Three bands where the bass sings and plays, Brothers Till We Die, Grim Death and Pirate Queen. Although on Instagram It still slips its most personal and aesthetic contentit is in Tiktok where it has taken the total turn towards the analysis of public services. 11 tricks to dominate Tik tok Germinate a calçot. Always titling their videos such as ‘Kingo in public places’ and starting with a crazy serial number (“day 2302 …”), Ali Blackbet frequents especially inaccessible or twisted public services: the Madrid City Council, the market of the market of The Nationalthe CITY OF ARTS AND SCIENCEShe Royal Palace, A plane… and does it with a very special grace, starting with the same denomination of the act (“bend the scaffold”, “orchestrate a zarzuela”, “release the chulapa”, “eating soft and pissing hard”) and following by the frantic edition, full of surprises, winks and even planes of a thousandth of second that seem taken from a dark metal video clip. Humor speaks. The most unique thing is that Ali Blackbet really analyzes the bathrooms, and ends up making the viewer at your disposal a humorous, but quite firm criterion, what to expect in each public service. All this thanks to the variety and conciseness of the valuation parameters: cleaning, lighting, water temperature, thickness of the toilet paper, toilet shape, operation of the tank, location, access … Result: 187,000 followers in Tiktok and videos that walk between 200 and 600,000 visualizations. New moods. Ali Blackbet belongs to a new generation of creators, which collecting the witness of a previous generation of humorists whose work has diversified in other media, such as Victoria Martín, Gakian, Esty Quesada either Lalachushave radicalized the previous proposals. With even less complex and throwing themselves into a much more crazy humor and are not afraid of being shocking or offensive, there is a whole generation of creators who often have nothing to do with each other but that are germinating very interesting profiles. Cases such as Magdalenita and his resounding retransmission of the Mérida festivities, the trchants Unboxings of toys of Beh Joestar or the lip-syncs skidded Teresa Aranguiz. Or this Ali Blackbet that, without being exclusively a humor account, has already put on the table the expression “train your dragon.” There are days to those who cannot ask for more.

We thought that gasoline cars were much cleaner than diesel. We did not have the effect of the sun

by

For every 100 cars that are sold in Spain, just five are diesel. They are the latest data we have in Spain of registration, which reflects to what extent the diesel (despite having market niches in which It is still profitable) It has become an almost banished fuel in our country. And although it may be weird, it does not make 70% of the cars we bought were diesel moved. In fact, just over a decade ago. In 2014 the diesel lived his golden age. From its 70.06% market share It has plummeted. There are numerous factors that explain the rise and fall of diesel. For years, its price was so cheap (in fact it is still subsidized) than each buyer He poured liter calculations consumed For every 100 kilometers to know how long it would take to make investment profitable since they used to be more expensive motorizations. But over the years, emission regulations were drowning the diesel. Especially after the famous Dieselgate in which it was discovered that the Volkswagen Group (first defendant) and other companies trucan their emissions to offer data within the legality in the homologation exams to, outside them, contaminate more than allowed. With Euro 6, diesel were put much more complicated since 2015. For sample, the comparison between the demands made to diesel engines compared to gasoline and that You can read in this extensive article of Xataka in which all the normative change was explained: Limits for a gasoline engine CO (carbon monoxide): 1.0 g/km HC (total hydrocarbons): 0.10 g/km NOX (nitrogen oxides): 0.060 g/km HC + NOX (hydrocarbons and nitrogen oxides): 0.160 g/km (approx.) PM (suspended particles): 0.005 g/km P (number of particles): 6×10^11/km (6×10^12/km for three years for direct injection) Limits for a diesel engine CO (carbon monoxide): 0.50 g/km HC (total hydrocarbons): 0.09 g/km (approx.) NOX (nitrogen oxides): 0.080 g/km HC + Nox (hydrocarbons and nitrogen oxides): 0.170 g/km PM (suspended particles): 0.005 g/km P (number of particles): 6×10^11/km The problem is that, due to its own operation, A diesel is less pollutant in CO2 that a gasoline but expels many more particle emissions than They are very dangerous to the health of the human beinglike the Nitrogen oxides (NOX). Although the value was slightly higher for diesel, emission regulations were forcing manufacturers to squeeze the brain. With Euro 5 the particle filter. From Euro 6, the Adblue. These measures ended up banishing diesel engines of smaller cars. Well because they contaminated too much or because innovations to be installed in them It was more expensive both the product that did not make it viable. If we take into account the increase in the product, the bad reputation after the dieselgate and the innumerable statements On a rise in the price of fuel, now it is better understood The sudden drop in sales. All this explanation makes sense. Do you remember that Euro 5 forced to mount particle filters in diesel cars? And that with the Dieselgate the cars reflected some emission figures that were not real? A study now indicates something similar for gasoline cars. It is not that they are cheating, they point out that the emission regulations itself may not be enough to tell us how pollutants are our cars. A little effective particle filter In short, a particle filter is a kind of mesh that catches larger pollutant emissions before expelling them to the atmosphere through the exhaust pipe. Taking advantage of the heat of gases, the mesh takes temperature and burns the particles, reducing emissions. That is a problem in the cars that start and stop every time or those that do many kilometers by city because the engine does not give time to take the temperature enough to burn these particles and the filter ends up collapsing, causing a somewhat expensive breakdown. For some years, emission regulations have forced gasoline cars to also mont particle filters to get emissions not to exceed the allowed limits. However, as a gasoline engine works at a higher temperature, It is more complicated to fall into these types of situations. However, a study published in Science Advances He has pointed out a problem: they are not enough. The particle filter aims to reduce the Volume of fine particles that are expelled to the atmosphere, PM2.5. And they get it, according to researchers but that is not enough to ensure that their toxicity is lower. They point out in their study that it is not enough to measure emissions just after combustion, they should be studied how they behave once in the atmosphere. And how do they behave?: Bad. They point out that, once in the air, the experts expelled are exposed to sunlight and that they cause a series of transformations that make them remarkably more toxic to the human being. They explain in Phys.org that the modification of the particles caused damage to the human DNA and in cells that we find in our bronchi. It is what they call “photochemical aging” that causes particles to increase their toxicity generating “oxygenated volatile compounds, such as carbonilos.” In the article they point out that Dr. Mathilde Delaval, the first author of the study and researcher at Helmholtz Munich, says that “our study shows that we are missing a large part of the panorama by not considering How exhaust gases changeand become more harmful, after leaving the car. “ The study is partially financed by the European Union and in it they have intervened in one way or another universities and laboratories of Germany, Finland and Switzerland.

presumably already has its first 6 -nm GPU for full games China

by

In China there are dozens of GPU designers for games and artificial intelligence (AI). The Chinese government has supported the proliferation of these companies with Very juicy subsidies in answer to US sanctions. Huawei, Metax, Biren Technology, Moore ThreadsInnosilicon, Zhaoxin, Iluvatar Corex, Deglinai or Vast Ai Tech are some of the most important, but there are more. Many more. And among all of them, it has just attracted the attention of the semiconductor industry: Lisuan Technology. This emerging company was born in 2021, in the same breeding ground triggered by The conflict held by the US and China which has also resulted in the constitution of other best -known graphic hardware companies, such as Moore Threads or Biren Technology. Although, as we have just seen, it is a very young firm, it is supported by veteran engineers who have developed a good part of their professional career in the US. It is exactly the same that happens with Moore Threads or Bire Technology, who tell in their ranks with former Nvidia employees. Lisuan has announced that it has a GPU as powerful as the GeForce RTX 4060 This week this company has revealed In your Wechat account Something important: it already has a GPU for games as powerful as the GeForce RTX 4060 of Nvidia. This is what Lisuan says, so the most prudent is that we collect it with reservations. When this graphic hardware is finally available we will check if this statement is reliable or not. However, this is not all. The most relevant thing is that this company ensures that this GPU, which it has baptized as G100, is the first manufactured entirely in China using 6 Nm integration technology. SMIC is already manufacturing in its nodes of 6 Nm the GPU for the Ascend 920 of Huawei Lisuan has not confirmed which Chinese manufacturer of semiconductors is producing this chip, but in all likelihood it is about SMIC (Semiconductor manufacturing international corp), The largest Chinese manufacturer of integrated circuits. This company You are already manufacturing in its 6 Nm nodes THE GPU FOR IA Ascend 920 From Huawei, so it is perfectly credible that this chip for Lisuan Technology produces in those same nodes. To manufacture integrated 6 and 7 nm circuits using equipment deep ultraviolet photolithography (UVP) of the Dutch company ASML SMIC uses a technique known as Multiple patterning. This strategy consists in transferring the pattern to the wafer in several passes with the purpose of increasing the resolution of the lithographic process. It works, but is responsible for the performance by wafer Be clearly improvable. In any case, Lisuan has revealed some more data about its G100 GPU. Apparently this graphic processor will work side by side with a generous vram memory map (it is only a conjecture, but it will possibly be 16 GB), will have moderate energy consumption And it will be compatible with the API Directx 12, Vulkan 1.3, OpenGL 4.6 and OpenGL 3.0, so it should be able to deal with current video games without problem as long as their controllers are up to it. Whatever the first graphics cards equipped with this GPU will be available during the third quarter of this year, although it is likely that large -scale manufacturing arrives at the beginning of 2026.

Keeping our data on the Internet is not as easy as it seems. Introduce personal data in portals can make them end up in the hands of criminals or scammers, to the point that suffering attacks from Phishing It is something relatively common. Having tools that protect us to the maximum is ideal, although it is not always easy to find them gathered. Surfshark does have them in its surfshark one plan. The best thing is that it only costs 2.69 euros a month. Surfshark One Subscription – Monthly * Some price may have changed from the last review Surfshark One Plan has VPN and much more This surfshark plan goes a step beyond its Starter subscription. Surfshark One includes the two tools that come in the aforementioned plan, or what is the same, its VPN that will serve to connect to the Internet safely (even in public networks such as those of the hotels) and ALTERNATIVE IDthat will create fictitious data so that we can use them on any website. In addition to these two tools, the Starter Plan comes with three more additional. The first one is called Alternative Numberwhich does the same as the previous one but with a phone number. In addition, we have Surfshark Alertwhat will do will let us know if a data filtration occurs on the Internet and our information appears in them. It is very useful, especially since the notification will come automatically without us having to do anything. Surfshark itself, in fact, has a scanner that allows us to check in real time If our email has been filtered on the Internet. It is very simple to use: it is enough to enter The page you have for this and enter our data. As we have advanced above, Surfshark One Cuesta 2.69 euros a month now that it is promoting. That means that two years of the complete service will cost us 72.63 euros, a discouragement if we take into account that its usual price is 484.65 euros. Also, there does not end the thing: We will receive three months extra giftso we will enjoy 27 months instead of 24.

There is a career to achieve the cheapest and most powerful model. And against all prognosis, China is winning it

by

On May 20 Google launched Gemini 2.5 Pro and Gemini 2.5 Flash in preliminary version. These new AI models were better than ever, and to demonstrate the company included in its announcement several graphs and comparative tables. They looked at how both surpassed their rivals both in the field of reasoning and in the traditional performance (Benchmarks of Mathematics or Programming), but there was also another fact that Google presumed: Google: The cost of Gemini 2.5 Flash. Source: Google. That table published by Google made it clear that Gemini 2.5 Flash It was clearly the winner of that comparison in the important price/benefits ratio. What Google did not say is that this success of this model was the exception to the rule, because in that race for having cheap and powerful models, China seems to take the lead. He does it at least if we attend to the cost of using these models. In Xataka we have analyzed that cost based not on the price of subscriptions for end users, but on the cost of access to the API, which is the one that allows developers to integrate these models into their own chatbots and their services. The API prices of each model clearly differentiate two uses from artificial intelligence. On the one hand, how much does it cost to write something for the model to then process it (the so -called input tokens). On the other, how much does the text generated by the model once processed the answer (the so -called output tokens). The entrance tokens They are usually five times cheaper than exitbecause processing the request and generating text is much more expensive than receiving it, analyzing and “understanding it.” We wanted to compare the cost of the main models of the AI ​​developed in China and those of the US, and although as always are not all that are, if they are all. The resulting table is as follows: These prices are public and very easy to find in the case of US AI models (OpenAI, Anthropic, Google) but not so much in the case of Chinese models (Deepseek, Qwen (Alibaba), Doubao (Bytedance), GLM-4 (Zhipu), Ernie (Baidu)). Be that as it may, the table, ordered from the cheapest to the most expensive, demonstrates that today Chinese models are especially cheap. Only Gemini 2.5 Flash Preview manages to compete – and does it exceptionally. In the rest of the cases, the AI ​​models in China win the battle for cost. It must be noted that, Like all comparisons, this is unfair. And it is because that table does not take into account the benefits of each model. Openai O3 and Anthropic Claude Opus 4, the last and most powerful models of those companies, are especially precise in their answers, but each consultation consumes much more resources (computation, energy) and that makes it logical that they are much more expensive than their competitors. But these models are also designed for very special cases and for specialized, detailed and deep consultations. In the vast majority of cases it is not necessary to use these models, and that is where they are competing for example Deepseek R1 or Gemini 2.5 Flash Preview: in the price/benefits ratio. Models with variable prices That price battle has made us see in recent times two techniques that some companies are applying to the prices of use of their APIs. The first one is to differentiate normal entries and outputs of inputs (and even exits) cache. Deepseek API prices. Attentive to the lower left: according to the time you use them, they can leave cheaper. Source: Deepseek. The explanation is simple: a “normal” entry is a request or question that the model has never processed and therefore has to process completely. If the entrance has been caught (Cache hit) is because that request has been processed in the past, so the system can obtain the response of its cache, which significantly reduces the computational costs. Deepseek, Google, Anthropic and Openai offer this type of option, as can be seen in the table. The second technique is to use variable prices according to (at the moment) the time slot in which we use these models. This is what Deepseek has done, which has “day” and “night” prices according to UTC schedule. If you use the Depseek API from 18:30 to 2:30 (Peninsular schedule in Spain), it will be half price. Good news: AI is every time (much) cheaper While China and the US fight who has the most powerful model or who has the cheapest model, what is constantly happening is that the AI ​​price is falling remarkably. It is an observation that several experts such as Ethan Mollick, a professor at the University of Pennsylvania who recently analyzed how That price/benefits ratio does nothing but improve. The models are getting better and cheaper. Other experts such as Raveesh Bhalla – explained by Netflix and LinkedIn – also reflected this evolution at the beginning of the year. Then he showed how the cost of an O1 level model had dropped 27 times in the last three months. Moreover, at this rhythm the GPT4 level models – which a year ago were absolute referents – will be reduced 1,000 times in just 18 months. We are living it in price reduction. Dane Bahey, from Openai, said at a conference in September last year how the cost per million tokens had fallen from 36 dollars At just 0.25 dollars In the last 18 months. And that price drop is still clear and fantastic for users. Thus, we are facing a career that at the moment has a lot of stretch: China’s models carry the lead if we attend only to their cost, but careful, because we must also take into account the benefits. It is true that these Chinese models have already shown in the benchmarks that have been showing that they compete from you to you with the best US models, and now it remains to … Read more
