Model

The O1-PRO model of Chatgpt Pro is 140 times more expensive than the Chatgpt O3-mini. What is not clear is that it is much better

by

Paying $ 20 per month for accessing Chatgpt Plus did not seem too serious. The thing began to get interesting when Openai launched its chatgpt pro subscription at 200 dollars a month. But now there is an even more expensive version of these models, and this again shows that we are at the beginning of a worrying slope: that of AI prices. What happened. OpenAI He has just announced That O1-Pro, the most powerful version of its reasoning model, is now available through its API. Until now it was only possible to enjoy it in a limited way through the subscription to Chatgpt Pro, but now the developers can also create services with it. The striking is not really that the company offers this version, but the price at which it is available. 140 times more expensive than O3-mini. As we said, O1-Pro is only limited to Chatgpt Pro users. If someone wants to use it intensively through the API, prices They are really high: O3-mini O1 O1-PRO Price for 1m tokens input (dollars) 1.10 15 150 Price for 1m tokens output (dollars) 4.40 60 600 As can be seen, O1-Pro is 10 times more expensive than O1, and about 135 times more expensive than O3-mini, which is the version of the reasoning model that for example we can use (limitedly) in the free version of Chatgpt. Gold Price Tokens. That cost imposes an important barrier for those who want to use this AI model for projects in which we introduce a lot of text and want to obtain a lot of text. For example, if we want to analyze a lot of documents and We saturate The input context window (200,000 tokens) and the output (100,000 tokens), we will have a cost of $ 90 … for a single question and an answer (an API request). But is it really so good? Preliminary O1-Pro impressions in Chatgpt Pro They were not especially striking according to whom They have tried italso They have protested for one falling quality. According to Openai O1-PRO, it offers “responses that are better consistently”, and highlight that it is an O1 version that uses more calculation power to “think more and offer even better responses to the most complex problems.” For asking not to be. IA companies are losing a money training their models, but they hope to recover it with a simple technique: increasingly faces. Data leaked in The Information also pointed out how Openai were already raising how an AI agent could replace a “human doctorate” to investigate, the cost would be $ 20,000 per month. They seem faces, but maybe they don’t. Of course, the price of these subscriptions and these accesses to the API may seem expensive, but they can also be a true bargain. What matters here is the profitability that we can get out of these models of AI: if they help us generate many more income, we will end up having “robotic employees” who work 24 hours a day, seven days a week and also do so with a productivity and quality of theoretically extraordinary work. But of course, we will first have to use them like this … and ensure that these results are effectively valid, something that for now does not seem so clear. In Xataka | AI agents are promising. But as in Tesla’s FSD, you better not take your hands from the steering wheel

The European model will never be the same

by

The European Commission has required Apple to open nine basic functions of iOS to developers and external manufacturers, transforming the iPhone experience in Europe. As we explain in Xatakathis decision represents the first great coup of authority of Commissioner Teresa Riberawho has also rebuked Google to favor their own services in the search results. Beyond the news, We are facing a turning point: The iPhone in Europe will never be the same. Why is it important. This intervention will directly affect the experience of millions of European users. Functions that have defined the exclusivity of the Apple ecosystem – as Airdrop, AirPlay or absolute synchronization with Apple Watch – will soon be available for competition products, altering the very essence of the iPhone as we know it. We are not facing a simple legal requirement, but before a forced redefinition of what an iPhone in Europe means. Between the lines. The European Commission has accurately identified where the opening hurts more. The selected functions are not casual: they are precisely those that create the “Blocking effect“That keeps users within the Apple ecosystem. When opening these characteristics, the EU not only seeks to encourage competition, but systematically dismantle the barriers that Apple has built for years to retain users. It is a direct attack on the company’s strategy. What is happening. For the first time, regulators are specifically dictating how IOS should function, with a detailed implementation calendar: Notifications should be shown in third -party watches by the end of 2025. The automatic device change will work with third -party headphones for June 2026. And the alternatives to AirPlay must be available by the end of 2026. This means that iOS 19 and 20 will include functions and APIS that Apple would never have voluntarily implemented, creating a very different operating system from that in the rest of the world. The big question. Is this “open” iPhone better or worse for European users? The answer depends on what we value the most. On the one hand, interoperability will allow greater freedom of choice and potentially more competitive prices. A user can buy third -party headphones that work as well with their iPhone as the AirPods, or a clock that access the same functions as the Apple Watch. On the other hand, Apple warns that forced opening compromises privacy and security. The non -encrypted transmission of notifications to external devices, for example, could expose sensitive information. In addition, the resulting fragmentation could degrade the integrated experience that many users value. However, in the past we have seen movements that seemed unthinkable ( options for sharing in iOS 8the recent arrival of emulators wave forced appearance of third -party stores) that they have not had the dire consequences that were raised. The threat. The greatest risk for European users is to become second -category digital citizens. Apple has already demonstrated its willingness to delay functions in Europe, as happened with Apple Intelligence in general or with iPhone Mirroring in particular, and could intensify this strategy. If the company considers that the EU requirements compromise its platform too much, it would not be surprising that future innovations arrive first – or exclusively – to less restrictive markets. Or to the rest of the world. European users could face a dilemma: more options but less innovation. In summary. The European iPhone will never be the same again. The question is whether that will be for better or for worse. What is clear is that we are witnessing a historical transformation in which regulators have decided to actively redesign the most influential product of what we have of the century. The result of this experiment will define not only the future of the iPhone, but possibly that of all technological regulation.

Germany gets serious with nuclear fusion. His energy model shouts that this ‘Stellarator’ reactor works

by

The experimental reactors of nuclear fusion of type Stellarator They represent a very solid alternative to Tokamakas ITER either JET. And they are not precisely the result of a recent investigation. In fact, both designs were designed During the 50s of the last century. He Stellarator It was designed by the American physicist Lyman Spitzer and exercised as the foundations on which the Plasma Physics Laboratory of Princeton University (USA) was built. The design TokamakHowever, it was devised by Soviet physicists igor Yevguénievich Tamm and Andréi DMítrievich Sájarov from the ideas proposed a few years before by his colleague Oleg Lavrentiev. Both reactors were conceived with the purpose of confine Stellarator He received great support from the scientific community in the West due to its enormous potential. However, when Soviet and American scientists published their results and compared them, they realized that Tokamak design performance It was one or two orders of magnitude better than that of Stellarator. From that moment on, this last design was largely marginalized. The most obvious difference between one and the other lies in its geometry, but it is enough to investigate both to realize that the reactors Stellarator They still have a lot to say. Proxima Fusion has put a date to its demonstration fusion plant Type reactors Tokamak They have a toroid form (or donut), and Stellarator They have a more complex geometry that resembles them to a twisted donut on itself. However, the fundamental difference between these two designs is that the reactors Tokamak They require that the magnetic fields that confine plasma be generated by coils and induced by plasma itself, while in the reactors Stellarator Everything is done with coils. There is no current within the plasma. This means, in short, that the latter are more complex and difficult to build. In February 2023, the Wendelstein 7-X reactor managed In Europe we have a type fusion reactor Stellarator extraordinarily promising: el Wendelstein 7-X. It is installed in one of the buildings that the Max Planck Institute has for Plasma Physics in Greifswald (Germany), and its construction concluded in 2015. The first tests carried out in this fusion reactor between 2015 and 2018 came out as planned, so in November of this last year An important moment arrived in his itinerary: It was necessary to modify it to install a water cooling system that was able to evacuate more effectively the residual thermal energy of the vacuum chamber walls, as well as a system that allowed the plasma to reach a higher temperature. The works that required these modifications concluded successfully in August 2022. And in February 2023 the Wendelstein 7-X reactor reached an important milestone: it managed to confine and stabilize the plasma for 8 uninterrupted minutes in which it delivered a total energy of 1.3 gigajultos. During the last two years everything learned in the development and the first tests carried out in this machine has been used by the German emerging company Proxima Fusion. In fact, its founders come from the Max Planck Institute for Plasma Physics. His work is being financed by Germany, the European Union, and also by several private entities of venture capital. And it’s going very well. In fact, fusion physicists and engineers have published a scientific article in Fusion Engineering and Design which has already been reviewed by pairs and in which they detail the design of Stellaris, its reactor prototype Stellarator commercial. Your next step requires Build a demonstration power plant From its design that should be ready in 2031. Yes, in just six years. I hope you get it. If Alpha, which is what this test power plant will be called, the commercial fusion energy will be a reality before the next decade is completed. This is the authentic purpose of next fusion.

What is, news, differences, and how to access the new artificial intelligence model of ChatgPT

by

Let’s explain What is and what news brings GPT 4.5the new artificial intelligence model launched by OpenAI for Chatgpt. Two years after a GPT 3.5 that revolutionized the industry and the technological world, this transition model between GPT-4O and GPT-5 arrives. We are going to start this article explaining what GPT-4.5 is, in case you still don’t know what this type of technology is. Then, we will tell you the novelties that it brings and how it differs with ortho models. And then, we will tell you how you can access him and those who can do it. What is GPT-4.5 GPT-4.5 is the artificial intelligence model of GPT-4 successor. GPT models are the artificial intelligence engine under chatgpt, The technology that makes it work. Over time new versions are coming out, and each of them have improvements that then apply to Chatgpt. Therefore, you don’t change chatgpt, but you can choose between the different engines that make it work. Of course, some are free and others are paid, and some work in one way and others from another. In the case of GPT-4.5, It will be the last model without a chain of thought. Some alternatives such as GPT-4O They are able to reflect on your question and how to face the answer before answering. However, this new version does not, so it looks more like GPT-4 than to other later models. GPT-4.5 is The largest and most advanced language model Posted by Openai to date. Not only is it more natural, but it has A much higher knowledge base with which to be able to face more complex challenges in scientific disciplines. It also improves its ability to solve logical problems. But one thing you have to know is that we have a version of GPT-4 freefor now GPT-4.5 is going to be paidand only subscribers can use it. The logical thing would be to think that they later take out a “mini” version somewhat more limited to use free of charge, but for now there is no date for it. How is GPT-4.5 As we have advanced a little higher, GPT-4.5 continues to advance in the resolution of tasks, and thanks to having a greater knowledge base improves the responses of their predecessors in logical problems, and is able to answer better questions in scientific disciplines. In general, The less hallucin modeland it is more truthful in your answers, a logical improvement for each new version that is coming out. But one of its most differentiating characteristics is in Emotional intelligence. This model is able to detect the tone in which you write a message, and respond in a consistent way. For example, if you notice frustration in your message the answer will be calmer and diplomatic. In addition to this, shows more solidity in complicated questions whose answer is not clear. For example, if you ask what the language would tell you that Nolo knows, and will explain that scientists do not believe we know it because they were invented before written records. Then, it will give you a series of points about what is currently known. To get this, OpenAi has added New supervision techniques for the learning of your model, which bind to traditional methods such as the supervised fine adjustment (SFT) and learning by reinforcement based on human feedback (RLHF). In short, we have a model that will significantly improve the answersand also the tone with which it responds in the cases in which you write in an emotional way. How to access GPT-4.5 For the moment, GPT-4.5 is going to be a payment model. The first who can start using it are the subscribers of Chatgpt Prothe company’s 200 dollars plan. But from next week it will also begin to be available in the subscription Chatgpt plus of $ 20 and Team. For the moment Nothing has been said about a free version. Normally Openai always leaves their best models for those who pay, so it is logical to think that it will take a few months to launch a free version, and that it will have some type of limit when it arrives.

Openai steps on the accelerator in the AI ​​race with its new and advanced language model

by

The career for the development of artificial intelligence does not stop accelerating. In November 2022 we witnessed the launch of GPT-3.5the model that laid the bases of Chatgpt and marked a turning point in the The conversational. Almost two years later, we are facing the arrival of GPT-4.5a new evolution that aims to continue expanding the limits of this promising technology. We are facing a transition model between GPT-4O and GPT-5, but with a key role in OpenAi’s strategy. The company has decided that GPT-4.5 will be the last without incorporating “chain of thought”, giving way to a new generation with incorporated reasoning capabilities. This change seeks to improve the clarity of your family of products, that has become complex over time. A more advanced model, with greater emotional intelligence AI is reaching a point where we no longer settle for having models capable of solving complex problems. That improve in programming, science, engineering and mathematics is very good, but we look for models that can interact with more spontaneous way With humans. This makes us understand OpenAi with GPT-4.5. His new language model is presented as the greatest and most advanced published by the startup to date. The researchers affirm that it is not only more natural, but their knowledge base has expanded to face complex challenges in various scientific disciplines, while improving their ability to solve logical problems. GPT-4.5 wants to stand out for its emotional intelligence, and in a recent test it has proven to live up to it. A member of the OpenAI team tested his abilities by sending him a message full of emotion. With a natural tone and Without hiding your anger, He explained that a friend had canceled him at the last minute and asked for help to write a message that reflected his discomfort. Chatgpt with GPT-4.5 detects that the user is frustrated and, instead of enlivening the anger, he suggests a calmer and diplomatic message to express his discomfort without damaging friendship: “Hello, the truth is that it has annoyed me a lot that the plans have been canceled again, I really wanted to see you. Can we talk about what is happening?” To achieve this change, Openai has modified its focus on creating models. Not radically, but incorporating New supervision techniques Together with traditional methods such as the fine supervised adjustment (SFT) and learning by reinforcement based on human feedback (RLHF), which were already fundamental in the development of GPT-4.

Anthropic launches Claude 3.7 Sonnet, a “hybrid” model that is better than ever. Not only that: also “reason”

by

Anthropic has announced The launch and availability of Claude 3.7 Sonnet, its new model of founding. The jump is promising, but stands out especially for one thing: they point to reasoning models. It is not Claude 4.0, it is Claude 3.7. The number of the new version confirms once again that the jump of benefits does not justify a more “round” number. Many expected Claude 4.0, but in Anthropic they make it clear that this is a much more evolutionary version than revolutionary. A hybrid model. In Anthropic they presume from having a hybrid model that does not differentiate between whether to talk and answer questions quickly, reason or any other application, because everything is based on the Claude 3.7 founding model, which does everything and behaves in that way Multidisciplinary. And as it does everything, it is somewhat more expensive than the competition: its API costs $ 3 per million input tokens and $ 15 per million departure tokens Claude can already “reason”. In a separate announcement Anthropic told us about his new mode of reasoning, called “Extended Thinking Mode”, which now becomes a more option among which we can display when using its model. If we activate it, the model “will think more deeply about complex questions.” As those responsible explain, this mode uses the same AI model, but does so by giving it more time and investing more effort to reach an answer. How Claude thinks. This mode of reasoning offers the possibility of seeing what the model is thinking when processing those answers. Here they warn that this information can be surprising, because we can see how AI can “think” incorrect things, but also show that process does not mean that the answer is only based on it. “Our results suggest that models often make decisions based on factors that are not explicitly discussed in their reasoning process.” Things are saved. That is: the model seems to keep things for yourself while thinking, but it is not clear which or why. There is another reason not to show everything: that raises security problems, since having all that information potentially gives resources to bad actors to take advantage of the model of inappropriate forms. Source: Anthropic You can play Pokémon alone. The new Anthropic model is also more “agéntico” than ever. It responds better to changes in the environment and continues to act until an open task has been completed. That makes The “Computer Use” function which allows AI to control our computer to be increasingly promising. They demonstrated it with Pokémon: Claude 3.7 came much further than previous models. Claude Code arrives. The Anthropic model has always highlighted in the scope of programming, and now they wanted to promote that capacity with Claude Code, a BASDA tool in Claude 3.7 Sonnet but specifically focused on helping programmers to develop their projects. A programming agent. This could also be considered as Anthropic’s first agent, because Claude Code is able to complete programming projects autonomously without needing user interaction. Thus, Claude can search between basis with code on which to base, read and edit files, write and execute tests, publish the code in Github repositories and execute commands on a console while informing developers of the entire process. He Anthropic demonstrative video It allows you to check some of those functions. Similar to Grok3 in performance. The new Grok 3 presented these days by XAI showed one more step in its performance in the most demanding benchmarks today, and Claude 3.7 is also in that line, which means that It is something superior In those tests to models such as O1 and O3-mini (from OpenAI) and Deepseek R1.

What is and main novelties of the new artificial intelligence model of Xai

by

Let’s tell you The novelties of Grok 3the new artificial intelligence model launched by XAI. This is the passage of Elon Musk’s company in the war to get the best chatbot of AI, and with which he adds to Grok reasoning capabilities. We are going to start explaining what exactly Grok 3 is, so that if you had never heard of it you can understand it. Then, we will explain the main differences of this model and why it is important. What is Grok 3 Grok is the name of the XAI artificial intelligence model, Elon Musk’s company. It is a model of AI like Gemini of Google or GPT of OpenAi. In the case of Grok, it is the model that uses the Chatbot Grok (yes, they have the same name) linked to the social network X, so much so that to be able to use it you need to have an account in this social network. As each artificial intelligence model, Grok 3 is the version released in February 2025, and that at the time of writing this article is the most modern version. So, It is a version that improves the characteristics of Grok 2and that offers more advantages. Just as other AI models are also evolving and improving, Grok does the same, trying not to be left behind in the frantic career of this technology. Elon Musk had promised a true revolution with this new version, although finally it is simply at the height of the competition. Another thing you should know is that Grok 3 is a family of models, with Grok-3 and Grok-3 Mini. The first is the complete model with all functions, and the second is a smaller one that offers balance between speed and quality of responses. What news brings Grok 3 The first difference is that while Grok 2 became free for all users, Grok 3 is going to be a payment modeland you will need to pay a subscription to use it. It will be available in the premium+ subscription of X, which costs 22.08 euros per month, or on an official new website that is not yet available in Europe. As for the model itself, the main novelty is that This model is able to reasonsomething we have already seen in the rest of the AI ​​models. With this, the AI ​​can generate more precise answers by analyzing the different response options before offering the final result. This reasoning capacity, as in other models, is optional. But if you choose it, another difference is that Grok 3 will hide the reasoning processesbeing less transparent than competition. Even so, it offers the possibility of generating multiple candidate responses. The other great incentive of this AI is that it allows Offer answers without filtersso some can be politically incorrect. This means that there will be very little self -censorship, and that you can ask almost anything. According to the companyGrok 3 has surpassed several competition models in benchmarks or test banks used to measure the AI ​​capacities. It has been above models such as GPT-4O, Deepseek V4 and Gemini 2 Pro in non-reasoning tasks Grok also improves in computational capacity, training with 10 times more computing capacity than Grok 2, and has been trained with a powerful 100,000 GPUS NVIDIA H100 cluster. In parallel to Grok 3 we have Deepsearch, which becomes the artificial intelligence -based search engine, and that Grok 3 will use. It is a tool that functions as a chatbot capable of reasoning, and that can navigate online and create Detailed reports to offer in -depth information on topics you ask.

The owner of a Tesla Model and has filled his roof of solar panels to load “up to 100 km”. It is not a good idea

by

He Solar car It’s like gold for the electric car. There, all wishes will be fulfilled: we will load our cars free of charge. End of the bonds of electric and oil forever. But we are so far from getting something like the gold appears in our lives. Different companies have proposed to experiment with the solar car and even sell their own models. Toyota, with the PRIusit filled the roof of it so that its plates would help the electrical components of the car. Mercedes, in his EQXX visionhe has played with the same idea. And, despite everything, from Sttutgart to Silverstone, a trip in which they toured more than 1,200 kilometersthey barely managed to extend the autonomy of the vehicle in less than 50 kilometers. But the Marketing From a solar car is very far. In the PRIus He contributed little. The Mercedes is a prototype designed to look for the limits of efficiency, both in aerodynamics and in chemistry of its batteries and consumption of its engines, so it is not too representative either. The 3.57 kWh recovered by the solar panels yielded much more in a vehicle of these characteristics than in a street car. Sono Zion, one of the most advanced projects, He ended up canceling. Those responsible for Lightyear, who said they were able to travel for free 70 kilometers daily with their solar car, have also ended by Lower the blind. In fact, since the vehicle was announced in 2019, its managers did not stop lowering expectations and, with them, the number of kilometers per year that the car could travel thanks to its solar panels. But all this has been no impediment to the owner of a Tesla Model and that ensures in Reddit having made your electric SUV a much more efficient vehicle thanks to some solar panels distributed along the ceiling. Figures that, of course, you have to take with tweezers. Putting it in quarantine As he has counted in a thread of Redditthis owner of a tesla model and ensures that he has designed a system of Foldable solar panels that allow you to load every day between 30 and 100 kilometers a day. In the presentation of his project, the user explains that the panels are folding and installed on the roof baca. He assures that in this first version, the panels stand out about 27 centimeters from the ceiling of the vehicle but that, in a new version in which he is working, he will reduce the height to about 15 centimeters, improve the flush and create a carbon fiber support To lighten the set. In total, the Tesla Model and can carry in the future, always according to the user, 4,000 W packaged On the roof, which once deployed can recover part of solar energy, transform it into electricity and recharge the car while it is parked. But many doubts arise here. First, he assures that He is working So that the solar energy is transformed into electric and goes directly to the car battery so, we understand, for now the energy is stored in a battery that subsequently recharges the vehicle. The other great doubt that arises is about the true efficiency of the whole. In 2019Toyota created a prototype of the PRIus that filled the entire roof, the rear window and the hood of the solar panel car. A surface that generated 860 W. With them, Toyota said he could travel some 45 extra kilometersbut they were based on the Japanese homologation cycle, much more lax than Europeans. In the case of Tesla Model and, the weight of the panels touches the maximum of 75 kg that in the United States can move on the ceiling, so it will irremediably affect consumption. First of all, those 75 kg of weight, which is more or less like going with one more person in the car. And, much more critical, for the impact on automobile aerodynamics, which would be very damaged. The creator says that he has not calculated the latter but believes that consumption worsens at 10%. All this has led some Work reviewers To affirm that the car can barely travel a little more than 40 kilometers under real circulation conditions. That without entering into the impact that the solar panels have on the dynamics of the vehicle and the march comfort, because it must be difficult to ignore the generated noise.

The mechanical keyboards I had tried did not convince me. Until I found the ideal model for me

by

For years I have felt special predilection for low profile keyboards that are common in laptops and that for some time they are also available as peripherals for desktop PCs. I feel especially comfortable writing with them, and I like their silent behavior as much as the fact that I do not need keyboards with large tours. Membrane technology is in my opinion perfectly valid for many users, but the bug of working daily with a Mechanical keyboard. Although I tried models in the past and I came to buy some years ago – the Xiaomi Gaming Keyboard – it seemed quite noisy and I did not get used to the touch and route of the keys. That has made a vetusto used for years Logitech K800 which is wireless but whose rechargeable battery no longer left much maneuver. I ended up changing the rechargeable AA batteries, but the truth is that even with that change it seemed to recover its ancient luster. That made Christmas to consider other options. I raised a logitech mx keys s, but I didn’t have just convinced the format, and I thought it was perhaps the time for try a mechanical keyboard. One that will adjust to my preferences. And specifically, two. The first, that was low, or at least relatively low profile. The second, to use also relatively silent switches. In recent times, several models had appeared with these two characteristics, but I noticed especially in two. NUPhy Air 96 The first the NUPhy Air 96which seemed especially striking for its design and had very good reviews in forums such as Reddit’s. The second, the Keychron K5 Maxwhich was also highly recommended by users and had a more traditional design. In both cases I was looking for a keyboard that included the mechanical keyboard, something that I do not use too often but that I am used to having. However, the NUPhy has a problem: its keyboards are available with an ANSI keyboard maps, very common in the US, but not with ISO keyboard mapsmore common in Europe (Enter -shaped key of l inverted, or, for example, Eñe key in its Spanish version). Keychron K5 Max I would not have had special problems when working with an ANSI keyboard – you can always mapping Spanish without problems – but I preferred, having both options, not having to “think” about it and ended up deciding for the Keychron model. Once arrived, the truth is that at first I felt something strange. Despite being a low profile keyboard, the height and route of the keys remains higher than the keyboards such as the K800 to which it was accustomed. But of course what caught my attention was that touch and sound of the keys when they were pressed. Unlike other mechanical keyboards that I had tried, the sound of Keychron K5 Max is in my opinion totally bearable. Moreover: I would say that it is elegant and almost addictiveAlthough that I think it ends up being the feeling for many other users of these keyboards: that sound and touch make it really seem to be desired to write more. It is a curious sensation. The arrangement of the keys is something different from that of my old Logitech K800, especially in regard to the function keys, but the keychron has important advantages. It has PC mode (Windows) and Mac to automatically “map” the special PC keys (such as the Windows key) or those of Mac (Option and Command). More interesting is still the switch that allows you to connect to three different devices: I can use it with direct USB-C cable, with Bluetooth connection or with the RF adapter that is included in the form of a small USB-A small pendrive similar to the receptor of my logitech K800 . Although I started using the Bluetooth connection with the Mac, I have preferred to finish connecting it with cable to reduce latency and possible conflicts and interference in the Bluetooth connection. Another of the always striking elements of these keyboards is that of the backlighting options. Here the effects are numerous and almost more typical of a gaming keyboard. It is easy to activate and deactivate back+tab back+tab and change from one effect with the fn+q keys combination. It is curious that to configure the keyboard we do not even have to install an extra utility: it is enough to access A KEYCHRON WEB SERVICE To “connect” our keyboard and from there access to various options such as configuring the key map, background light or macros. It is also possible Update the firmware of the keyboard, although the manufacturer recommends not modifying it except that we have a problem we have installed with. The truth is that after a month using it, the Keychron K5 Max has become a great co -worker. As I say, their touch and sound have already ended up part of my routine and Now I better understand that attraction that usually cause mechanical keyboards among their users. I still believe that membrane keyboards are a good option, comfortable and quieter, for many people, but it is evident that mechanical keyboards have something special, and now the thing has been encouraged even more with the appearance and appearance and appearance and Popularity of the ‘Hall Effect’ keyboards. I am very happy with my Keychron keyboard. Keychron K5 Max Ultrafine Wireless Mechanical Keyboard, QMK/Via programmable, 3 Bluetooth modes/2.4 GHz/Cable with RGB LED, Low Profile Gateron Red Switch Hot-Swap, PBT Keys * Some price may have changed from the last review In Xataka | “Hello, computer”: the future that paints the AI ​​of Anthropic is now the same one that Star Trek raised in 1986

free access to your reasoning model

Google has announced he Gemini 2.0 launchtheir new family of AI models. They actually launched experimental versions of Gemini 2.0 Flash in December And above all they showed their preliminary reasoning model, Gemini 2.0 Flash Thinking, but now all those movements are consolidated with more mature and stable versions. Best of all, Gemini 2.0 Flash Thinking, OpenAi O1 or Deepseek R1is already available as one of the available models In Gemini’s mobile and desktop application. Gemini 2.0 is more “agetic”, and according to Google it can “interact with YouTube, Search and Google Maps.” The company announced these days bittersweet fiscal results: they have more money, users and benefits than ever, But they are on the defensive. SUCTAR PICHAI, CEO of Alphabet, highlighted how the company will invest 75,000 million dollars in AI for 2025, when its CAPEX (capital expenses) in 2023 was 32,300. The decision shows that clear intention to invest but not necessarily to lead, but to try not to be left in front of a competition that also seems willing to spend colossal amounts of money. One of the outstanding notes of this Google announcement is the launch of a Experimental version of Gemini 2.0 Pro. This model, successor of Gemini 1.5 Pro, is more precise and “factual”, and according to Google exceeds clearly to the previous version in programming tasks and mathematics related. Google qualifies Gemini 2.0 pro as “your most capable model so far”, and will be available for GEMINI Advanced subscribers and for those with access to VERTEX AI and AI STUDIO. Together with Gemini 2.0 Pro is Gemini 2.0 Flash-Lite, a lighter version that offers more quality in its response than the previous Gemini 1.5 Flash, but that maintains its speed and cost. This model has a gigantic context window (One million tokens) and multimodal support, and for example you can generate a brief description of a line for a set of 40,000 different photos … and all for less than a dollar, indicate those responsible.
