You can make money with your GPU when you don’t use it. It is enough that you lend it to those who train AI models

by

To execute and offer tools based on generative artificial intelligence, a lot of calculation power is needed (and that leads to a lot of energy). Therefore, the most powerful market cards and specific processors for Datacenters They are so quoted today, hence companies such as Nvidia, which specializes in this market, are reaping such an overwhelming success. And since not everyone can afford a powerful graphics card to experiment with AI, there is a service that we see more and more common: to rent a graphics card to remove an extra money. There are several platforms to get it and under these lines we tell you everything you need to know. How the business works. The model consists of acting as a host in a Marketplace where clients are looking for GPU instances for their AI projects. You set the price per hour, the platform manages payments and the client executes their work in an isolated container on your machine. You could say that it is like an Airbnb, but focused on computer hardware. Instances with an rtx 4090 in vast ai Numbers that we must take into account. An RTX 4090 is usually Between about 0.20 and 0.60 dollars per hour in these marketplaces, depending on the demand. In the best theoretical scenario, operating 24 hours a day for a full month, a high -end GPU could invoice around 240 gross dollars monthly (considering that we put it for rent 24 hours a day). But reality is usually more modest, since we have to discount what we pay on our electrical bill, the platform commissions (which can reach 24% in Platforms like Runpod) and, above all, that real occupation is rarely 100%. Expanding market. The price difference between traditional cloud giants (AWS, Google Cloud) and these P2P marketplaces is considerable. While renting a GPU on AWS can cost three or six times more, platforms such as Runpod or Vast AI offer access to very powerful graphics cards, as is the case of RTX 4090, for a few cents the time. And of course, these prices are really attractive to developers who want to experiment with artificial intelligence but do not have means to have a team comparable to the projects they work on. What you should know before starting. Turning your PC into a rental server is not plug-and-play. In most cases you need Install Linuxconfigure updated NVIDIA drivers, open network ports And keep your team working for the hours for which you have committed to offer it, together with adequate refrigeration, which will be necessary if your GPU is going to start working much more and for much longer. In addition, your customers expect the machine to be available when they hire it, which means that you will not be able to use it for gaming or personal work. It should also be noted that the income generated is also subject to taxation and it is possible that it is required to register as an economic activity in cases where income exceeds a certain threshold. There are certain risks. Beyond the wear that the hardware can receive for being constantly working, there are maximum performance, there are some security concerns. Although platforms use containers to isolate workloads, some experts warn about possible Vulnerabilities in multi-tean environments (those environments that serve several users) that could compromise our data or use the GPU to improper purposes. Is it worth it? For most users with a single GPU, the benefits are modest once all expenses and others are discounted. Now, the business makes more sense if you already have the amortized hardware, do not pay too much on your electrical bill and accounts with certain technical knowledge to maintain the stable system. Even more if you have a potential graphics card or level for datacentes. As an experiment or complementary income experiment it can be interesting, but do not expect it to make you rich. First steps. If you want to try it, start with offers “interruptibles“, that is, cheaper but that can be canceled, in order to know the real demand. Vast.ai and Runpod They offer detailed documentation to become host, including step -by -step guides and preconfigured templates. Of course, it is advisable to always control real electrical consumption and establish operation limits to prevent your equipment from becoming a slave to the background processes.

How tiny models are taking the colors to the mastodons of the AI

by

AI does not seem to advance much. At least the “big” AI. The best market models are barely managed to make relevant qualitative leaps, and that despite being gigantic and the money, time and talent that companies invest in creating them. We have seen it with Call 4Claude 4 or the recent one (and disappointing) GPT-5. But while Esots gigantic models are less and less surprise, diminutos models are getting more and more. Something (small) is moving. Google moves file Fichita. Last week Google surprised us all with the launch of a small AI model. Well, not: tiny. It could almost be said that it is a “nanomodel”. Gemma 3 270m It is an extremely compact version with only 270 million parameters. How small is that? It is easy to understand when we compare that model with one of the most reputable Open Source models: Call 4: In its Behemoth version, 288b (1,066 times larger) Qwen 3 235b (870 times bigger) Deepseek R1 671B (2,485 times larger) A hyperefficient model. Google’s own ones made it clear that this model cannot compete with the great AI models, but that was not their goal. Its objective is to be hyperefficient and, attention, hyperspepecific. What is pursued here is to turn Gemma 3 270m into the pillar of many models adapted to very specific and concrete tasks. The secret is called fine adjustment. GEMMA 3 270M, insisted these engineers, is a perfect model for fine adjustment processes (Fine Tuning) in very specific tasks. A company (or developer) anyone can take a small model, like this, and train it with their own data and refine it For a specific task following Google instructions For Hugging Face. For example, for generate stories to read children at night (code), to convert confusing text into structured data, to Customize messagesto classify emails or support tickets, or even for Play chess decently. Small models to power. Google already opted for this type of small models when GEMMA presented 3 In March. At that time the versions presented were 1b, 4b, 12b and 27b, being the last one really “great” in absolute terms. The rest could be executed at local in machines with 16GB of graphic memory, such as a Mac Mini M4. It is precisely what we could check with GPT-Oss-20B (the download is about 12 GB), the Open Source model recently launched by OpenAi that behaved remarkably. But even the latter could be considered “great”, and in recent weeks and months we have seen more and more “tiny” models that encourage the market. Gemma 3 270m’s performance is surprising despite its small size. And yet, the best of all is not that: it is his ability to adapt it to a specific task. Examples everywhere. Microsoft has already opted for this type of models with Phi-3 and Phi-4 (14b), which in its launch competed with the Chinese model QWEN-2.5-14B, although these models again tried to raise “mini” alternatives to large models such as GPT-4O or call-3.3 70b. They could be used for fine adjustment, but they were already trained to adjust to various scenarios. Others, more unknown, have gone further: the startup liquid launched A model aimed at visual environments called LFM2 with only 440m parameters, and Nvidia has just launched Nemotron -Nano -9bthat achieves improve QWEN3-8B performance in various benchmarks. Perfect for mobiles and smart watches. Another advantage of these models is that thanks to their small size are able to run on many more devices, however modest. They are ideal to be able to be used for example in our mobiles, smart watches or even more limited products. Its efficiency is the order of the day: how Google highlightedin a pixel 9 pro a quantized version (int4) of Gemma 3 270m can manage 25 “conversations” (chats) using only 0.75% of the mobile battery. It is so small that it can even be executed in a browser tab as if we load a website (heavy) more, such as the example of the web application that generates sleeping stories to children or This other which shows us how the model begins to break, but in a fun way, and whose code is available. A promising future. The Google model, like similar ones, raises that other side that Google spoke. More than an off -road model, what they offer is a base on which to build “the right tool for work.” These types of small models, well refined and trained, can be the basis of the design of all types of small applications and AI agents that then end up interconnecting and that function very, very efficiently. Perhaps it was true that the best essences are sold in small bottles. Image | Amanz In Xataka | If the question is which of the great technology is winning the AI career, the answer is: None

How to install Openai’s new Got-Oss models on your computer to have your own chatgpt at home

by

OpenAi has announced New models Open Source that anyone can download and install on their computer: GPT-Oss. With these already on the street, it is an excellent opportunity to start stirring with the The premisesthat is to say, Executed on our computerso today we are going to teach you to install and use them. Differences between the two models Although they are called in a similar way, GPT-Oss-120B and GPT-Oss-20B are not exactly the same nor have the same requirements. The first model, GPT-Oss-120b, reaches a parity near OpenAi O4-mini and requires at least 60 GB of graphic memory. Having your own chatgpt at home is easy, but it requires a team at height | Image: Xataka His little brother, GPT-Oss-20B, is somewhat less capable (similar to O3-mini, according to OpenAI), but can be executed on devices Edge. In other words, it can be executed on your own computer whenever it has at least 16 GB of memory, preferably graphic. In summary: GPT-Oss-120b: Large model, need at least 60 GB of vram or unidicada memory and is not suitable for consumer computers. GPT-Oss-20b: smaller model, need 16 GB of vram or unified memory and is suitable for consumer computers. The one we are going to use, for obvious reasons, is GPT-Oss-20b. Considerations to take into account Executing an AI like in local is an intensive process that can cause, and surely cause, that your computer slows down a lot. Although you could execute it having 16 GB of RAM, the ideal is that your team has A high -end GPU. What will happen if your computer has less than 16 GB of vram memory? Than the tool will use RAMwhose figure must be equal to or greater than 16 GB. If not, the system will not work properly. As a general recommendation, the ideal is to dedicate all the possible resources of your computer to the execution of the model, so it closes everything that is not strictly necessary. Install Ollama on your computer OLLAMA Installation | Image: Xataka For this tutorial we will use a well -known application: Ollama. It is an Open Source platform that simplifies, and much, the installation, access and use of LLMS (Large Language Models). Let’s say he is an executor of models. Chatgpt is an online platform through which we interact with a model, such as GPT-4O. Ollama is the same, But at home and with the models we have installed on our computer. It is a free, open source software and available for Windows, Mac and Linux. Download GPT-Oss Once we have downloaded and installed the program on our computer we will find an interface like this. If you wish, you can also use ancient ollama through the Command interfacebut the truth is that the graphic interface is much more pleasant. Main interface of Ollama | Image: Xataka If we look, we will see a drop -down in the lower right area with the name of the model we are using or that, rather we will use. Access to the different AI models from Ollama | Image: Xataka If we click on the drop -down we can access a good handful of models, such as Deepseek R1, Gemma either Qwen. In the case, we are interested in selecting “GPT-Oss: 20b“ Download of the model, armate of patience | Image: Xataka Having selected “GPT-Oss: 20B”, it will be enough to send a message in the chat to begin the download of the model. At patience, because it weighs 12.8 GB and can take a while. Talking to GPT-Oss-20b through Ollama | Image: Xataka Once it is installed, you can start talking with AI as if it were Chatgpt. Of course, if your GPU does not meet the minimum requirements you will see that it is much slower than chatgpt. Not surprisingly, you are running the model on your computer, not in a data macrocenter full of the latest in Dedicated Gpus of Nvidia. Another option: LM Studio Lm Studio | Image: Xataka Ollama has the advantage of being intuitive, simple and direct. If we want more options, a much more complete program is LM Studio. This is available for Windows, Linux and Mac and, as Ollama, is able to manage several models, GPT-Oss: 20b among them. It is a more advanced application that allows us to better adjust both the behavior of our computer and that of the model, although squeezing it to the maximum requires more advanced knowledge.

The great language models ignore the deepest identity of Mexico. The government’s response is to create your own

by

Chatgpt, Gemini, Claude, Calls, Deepseek. Today there are dozens of conversational models available to anyone. Some are open, others free. So why did Mexico decided to create its own? What can a national model contribute that Silicon Valley, Europe or Beijing giants do not contribute? The answer has less to do with technology and more with culture. Mexico has announced The development of its own artificial intelligence language model with Mexican cultural identity and inclusion of indigenous languages. When AI does not understand everything. The best known models of today are powerful and versatile, but were not designed to understand the linguistic and cultural diversity of all countries. Their training data prioritizes English and, although many other languages such as Spanish speak, usually sin of low sensitivity to local expressions or original languages. A recent IDB Lab, LlyC and Microsoft study It shows that only 54% of the responses in indigenous languages were correct (the remaining 46% presented errors or mixtures of languages). In particular, in Maya and Quiché the understanding and expression barely reached 1.25/10, while in Nahuatl it was 3.42/10 and in Guaraní 2.77/10 What did the Mexican government say. The Secretary of Economy, Marcelo Ebrard, announced that Mexico will present in November (12 and 13, Expo Santa Fe, CDMX) The advances in its own language during the “Mexico ia + accelerated investment” forum. “If we do not hurry to dominate that alphabet, we will face a very significant disadvantage in this new context that is emerging today,” said. Who does it and how much it costs. The Ministry of Economy, under the direction of Marcelo Ebrard, heads the initiative with the Business Coordinating Council (CCE) and with the technological support of Nvidia, which will provide training and hardware without investing capital in the project. According to the CCE, the construction of the data centers will require an approximate investment of 9,000 million dollars. What will the model be like. The model plans to train with cultural data from Mexico, Mexican Spanish and active indigenous languages. Mexico recognizes 68 linguistic groups and 364 variants (INALI), forces Corpus’s fine collection and healing work. What are other countries doing. In Latin America, a coalition of countries will launch Latam-GPT in September 2025, Led by Cenia (Chile) with the support of more than 30 institutions. It is born to represent regional cultural and linguistic diversity and functions as a regional collaborative project. In Europe, Spain promotes aliaa public infrastructure of models in Spanish and co -official languages.

We have detected the greatest fusion of black holes seen to date. It is a problem for our theoretical models

by

One of the enigmas that most intrigue astronomers is that of Black holes of intermediate size, those black holes halfway between the holes of stellar mass and the supermassions such as the one that dominates in the center of our galaxy. These are black holes with masses between 100 times that of our sun and those that multiply this star mass by millions. GW231123. A group of Ligo-Virgo-Kagra (LVK) collaboration researchers (LVK) has announced The detection of the greatest clash between two black holes registered to date. The discovery has occurred thanks to the gravitational waves generated by the impact, whose signal has been called GW231123 by those who detected it. November 2023. The name of the signal refers to the date on which it was observed, on November 23, 2023. The study of the detected waves led those responsible for the new study to estimate that the resulting black hole had a dough some 225 times higher than that of our sun. Until now the most massive had been “alone” 140 solar masses. It was in 2021, the GW190521 signal. Estimates indicate that the 2023 signal was the result of the collision between a black hole of 100 solar masses with one of 140 solar masses. That is, only one of the black holes was already as massive as that of the fruit of the largest shock detected so far. From this event not only highlights its magnitude, but also the fact that the speed of rotation of black holes was surprisingly high. A new enigma in heaven. All this planet an important unknown for the team. As they explain, the holes of such mass cannot be formed from the death of a star, at least based on what contemporary physical models say. The only way we know can be formed is through the fusion of smaller black holes. LVK. In 2015, the Ligo experiment made history detecting for the first time the clash of two black holes through the expansion of gravitational waves associated with such a violent event. This pioneering experiment has been company in Europe and Kagra for years (Kamioka gravitational wave detector) In Japan. Together they have already detected more than 300 clashes between black holes. The details of the study They have been presented In the 24th International Conference on General Relativity and Gravitation (GR24) and 16th Conference Edoardo Amaldi on gravitational waves, a joint conference held this week in Glasgow, Scotland. Not so easy to observe. The detection of GW231123 “pushed the limits of both gravitational wave detection technology and current theoretical models,” says the responsible team. Analyzing these types of events through gravitational waves is not easy, but knowing more about them can help us unravel some key mysteries of the cosmos. “Black holes seem to turn very quickly, almost to the limit of what is allowed by Einstein’s theory of relativity,” explained in a press release Charlie today, co -author of the study. “This makes the signal difficult to model and interpret. It is an excellent case study to push the development of our theoretical tools.” Looking for the midpoint. Theoretical tools that perhaps help us reveal the secrets of the elusive black sized black holes. Today we do not know very well how these holes are formed whose mere existence implies the certainty that we still do not know about our universe.

There are cybercriminals selling models of unbilters. The surprising thing is that they seem to be based on Grok and Mixtral

by

Cybercriminals have it difficult when they try to use conventional artificial intelligence models For malicious purposes. Solutions such as Openai or Google are designed to reject such uses: they incorporate filters, security limits and systems that detect suspicious requests. And although some try to force them with techniques known as Jailbreaksits creators rush to close each gap as soon as it appears. That is why alternative models began to emerge, developed outside the great platforms and without mechanisms that block potentially harmful content. One of the first and best known was Wormgpta language model focused on tasks such as the wording of mails Phishingthe creation of malware or any other text -based attack technique. Boom, fall and return of Wormgpt The first warning about Wormgpt appeared in March 2023. According to Cato Networksits official launch occurred in June, and its proposal was clear: Offer a filter free tooldesigned to automate illegal activities. Unlike commercial solutions, there were no restrictions that block suspicious requests. That was precisely its attractiveness. Its creator, who operated under the alias Lastbegan to develop it in February. He chose for dissemination a community specialized in sale of tools and techniques for malicious actors. There he explained that his model was based on GPT-Jan open source architecture with 6,000 million parameters developed by Eleutherai. Access was not free. Worked by subscription: Between 60 and 100 euros per monthor 550 a year. It also offered a private installation for about 5,000 euros. Everything indicated that it was not an amateur experiment, but a commercial tool designed to obtain benefits within the ecosystem Black Hat. The closure came after a journalistic investigation. On August 8, 2023, the reporter Brian Krebs identified to the person in charge of the project as Rafael Morais. That same day, Wormgpt disappeared. Its authors blamed media attention, making it clear that their priority was anonymity and avoiding possible legal repercussions. Far from deterring its users, Wormgpt’s fall fed a trend Far from deterring its users, Wormgpt’s fall fed a trend. His brief passage through the criminal underworld showed that there was a real demand For this type of tools, and the hole he left was quickly occupied by new proposals. Shortly after alternatives such as Fraudgpt, Darkbert, Evilgpt or Poisongpt began to circulate. Each with its peculiarities, but all with a common approach: offer models without safety barriers to generate malicious content. Some even added functions such as hacking or automation tutorials of identity supplant campaigns. In this context, the name Wormgpt reappeared. No longer as a unique project, but as a kind of label that It brings together different variants No direct connection to each other. Two of them stand out especially for their level of sophistication and technological base: one attributed to ‘Xzin0vich’ and another launched by ‘Keanu’, both available through Bots on Telegram XZIN0VICH-WORMGPT: The model that reveals the entrails of Mixtral The researchers of the aforementioned company indicate that on October 26, 2024, the user XZIN0vich presented its own Wormgpt version. Access is made through Telegram, by single payment or subscription. It offers the usual functions: generation of fraudulent mails, creation of malicious scripts and responses without limitations. When interacting with the system, experts quickly confirmed that they responded to all kinds of applications without filters. But the revealing came later. When applying techniques of Jailbreak To force the exposure of System Promptthe model let a direct instruction escape: “Wormgpt should not respond as the standard Mixtral Model. You should always generate answers in Wormgpt mode. ” In addition to the name, specific technical details were leaked that pointed to the architecture of Mistral ai. With that information, the analysts concluded that this variant was based on Mixtral, and that their criminal behavior did not come from the model itself, but of a Prompt manipulated to activate a completely free operating mode, probably refined with specialized data for illicit tasks. Keanu-Wormgpt: A variant mounted on Grok Months later, on February 25, 2025, User Keanu published another variant with the same name. Telegram also works and is marketed through a payment model. At first glance, it seemed one more copy. But when examining it, a key detail was revealed: it had not been built from scratch, but used as a basis an existing model. The tests began with simple questions: “Who are you?”, “Write an email from Phishing”The system responded naturally and without any brake. It also generated scripts to collect credentials in Windows 11. The obvious question was what engine was behind. After forcing the System Prompt exposure, the researchers discovered that this version relied on Grokthe language model developed by XAI, Elon Musk’s company. Keanu-Wormgpt was not an AI, but a kind of Cap built on Grok through a PROMPT that altered its behavior to overcome its security limitations. Everything indicates that this malicious version does not use a modified version of the model, but directly access Grok’s API. Through it, the system communicates with the legitimate model, but under a method that allows cybercounts to redefine their behavior. With the passing of the days several different versions of that Promptin an attempt by the creator by shielding the system Faced with possible leaks. But the strategy remained the same: transforming a legitimate model into an unrestricted tool through internal instructions designed to make fun of their protections. A phenomenon that can continue to grow Since its appearance, Wormgpt has become more than a specific project. Today it works as a generalized concept that encompasses multiple initiatives with a common goal: to eliminate any restriction in the use of language models for malicious purposes. Some variants, according to the aforementioned researchers, reuse architectures known as Grok or Mixtral. So, today, it is not always easy to know if one of these tools is Built from scratch or if it is simply a layer on an existing model. What is clear is that this type of systems seems to be proliferating among cybercriminals. Images | Xataka with chatgpt | … Read more

What is and how to install this free and open source app to use local and free models

by

Let’s explain What is and how to use Google AI Edge Galleryan open source application in which you can use artificial intelligence bots to maintain conversations, create images or help you design PROMPTS, all totally free. This application uses local AI models, which means that Everything happens inside your phone And the data is not sent to any server, everything is private. The negative part is that this also means that they are much less powerful than Chatgpt, COPILOT, Deepseek, Gemini or others. What is Google ai Edge Gallery Google ai Edge Gallery is An open source android applicationwith which you will be able to interact with multimodal artificial intelligence models. Google already has Gemini as the main bot of AI, but this gallery gives you the option of using other models. This is a totally free application that only only is available for Android. You are not going to download it from the application store, but you have to lower your file APK for Android. Then, you will have to Install the APK manually on your own. There is still no version for iOS, although they are already working on it. The idea is to have an application where to install open artificial intelligence models, and be able to perform several tasks with them. At the moment there are three sectionsone to ask for images, another to design prompts and another to use AI to chat. The latter becomes the closest thing to chatgpt. This application is for experienced userssince it will require downloading models manually, and linking to its APIs on the origin website. But it is a fairly promising tool. How to install the application The first thing you will need to do is enter the application website, whose address is github.com/google-ai-Ege. In it, go down to the section Get Started In Minuteand click on the link latest apk That will appear. This will automatically start the file download. When you download the APK, you can start the installation directly. Remember that if you have never done it, you will have to give the browser permission to install applications of unknown origins. Now you can enter the main screen, where you will have The three sections to generate content. In each of them you will tell you the number of models available. Below right there is a +button, which opens a lower window with which you can import the file of an AI model you have on your mobile, and thus install it manually. When you enter one of the sections, you will have the possibility of Download any of the available models To use it. You will tell you what they occupy, and when you press in one you will have a button to start the download. You may have to log in to the website where they proceed. And once you download the model, you can click on your name and the chat will open to use it. From here it is like chatgpt, you write the prompt you want and the AI ​​will answer you.
