Microsoft had a saved secret. His new AI model for Copilot is the clearest statement against Openai’s domain

by

Since the fever broke out by generative AI, Microsoft has opted for OpenAi models to give life to key functions in some of its most important products. It is not strange if we remember that those of Redmond They invested more than 10,000 million dollars in the startup directed by Sam Altman. However, this alliance of convenience It has been showing fissures for months And, as time goes by, The rivalry between both parties becomes more evident. It was Microsoft itself that, a year ago, included OpenAI in his list of competitorstogether with Amazon, Apple, Google and Meta. And it is OpenAi who, According to The Informationinsists on not wanting to share its avant -garde technology when it arrives, if it arrives, the AGI. Even if you try to make up, the link is no longer as solid as in its first days. And now there is another chapter underway. Microsoft AI begins to show their own letters Mustafa SuleymanCEO of Microsoft AI, who assumed the position when the association with Openai had been consolidated for years, It has just presented two internally developed models. They are advanced proposals that users can already prove and reflect the company’s ambition: “Create AI applied as a platform for products.” One is a real novelty and another we already knew. Let’s look at the details. Mai-1-Preview. It is the great novelty. It is a Mixure-OF-Experts model, in the style of GPT-4O or GPT-5, designed to offer great capabilities in resolution of instructions and useful responses for daily consultations. According to Suleyman, it is the first model trained from beginning to end in Microsoft AI’s own laboratories. The most striking thing is that it can already be tested. Just enter LMARENAselect Direct Chat and choose Mai-1-Preview. In the coming weeks it will also arrive in Copilot, although only “for certain cases of text use.” It is paradoxical: the text functions of the Microsoft Chatbot work thanks to OpenAi, but now it will begin to live with its own technology. Developers can also request anticipated access to API. MAI-VOICE-1. It is a voice generation model that stands out for its expressiveness and naturalness. For some time now it promotes functions such as Copilot Daily (news summaries) and Copilot Podcasts, although only in English. It is also available in COPILOT LABSwhere you can try different voices, styles and narration tones. One of its strengths is efficiency: it can generate a complete minute of audio in less than a second using a single GPU. With this, it is one of the fastest and most effective voice systems that exist today. Microsoft defends that the voice will be the interface of future assistants of AI. And he wants to advance with a high fidelity solution capable of responding in different scenarios. Could I have resorted to Openai and your GPT-4o in audio version? Yes. Do you want to do it? Everything indicates not. “Much more to come. We have great ambitions for what comes next: advances in the models, an exciting roadmap in computation capacity and the opportunity to reach billions of people through Microsoft products. We are building an AI for all,” said Suleyman in X. It remains to see what course the relationship between Microsoft and OpenAi will take. What is clear to users is that there will be more variety and more tools to experiment.

How to edit your free photos on Google Gemini, and what can you do with the Nano Banana model

by

Let’s explain How to edit your free photos using Geminiusing the new “Banana” model that allows you to modify or add or remove elements. This is the new great evolutionary leap of the AI, which after Chatgpt allowed you to create images from photos now comes the internal edition in Gemini. This is something that you will be able to Make in the free version of Geminiyou don’t need payment. You just upload a photo and ask to make the changes you want, you don’t have to choose any specific function or model, because it is already something integrated within Gemini. Here, you should know that the great advance of this function is that the changes are made directly on the original photo. What you say, but Everything else is going to be kept in the photonothing will be changed. How can you edit your photos with To edit your photos, you first have to upload it and then Ask Gemini to make any change. Sometimes it will be enough to directly ask you to put it in black and white, for example. Other times, you can start the prompt with “In the original photo, XXX” And then write the change you want me to do. Thus, Gemini will know that you want to keep the content of the photo as it is. First, Gemini now allows you Make touch -ups in your photoshow to adjust the color, change black and white, and alter any adjustment you want. You don’t have to use an app for something so simple, you can ask Gemini directly. You can also delete objects from a photo. This is something that until recently also needed third -party apps, but both Chatgpt and now Gemini already allow you to do it. They eliminate the object you want, and cover the bottom of the photo so that it seems that there was nothing. When you upload a photo of yours or another person, you can also change elements in it. You can change colors, hairstyles, people, and even clothes that is being put in the photo. Do you want to know how platinum hair would look like? Easy. Do you want to know how you look in a suit? Easy. Everything else in the photo remains the same. You can also change some elements of one photo for othersalthough not always with realistic results. Do you want glasses? Do you want to? Do you want your cat to become a dinosaur? Everything else in the photo remains the same. In addition to this, you can also Upload two photos and make the content of one appear in the other. In the example, I have uploaded a photo of mine teaching a drawing, and I have asked to change it which appears in a second photo. Just be sure to specify in the photo you want to make the changes and what they are. And finally, you can also change the back of a photo. Thus, if in the photo you are in a place you can make it look like you are in another, or add elements that change the environment where you are.

The English Court changed the credit card model. And along the way it has become a Fintech

by

In just two years, El Corte Inglés has financed 1,372 million euros in purchases outside its commercial universe, according to reports Expansion. All for allowing you to use your card anywhere in the world. A silent transformation that has made these department stores an unexpected rival for traditional banks and Fintech emerging. Why is it important. With 11.7 million cards in circulation, the chain has converted its loyalty program of the sixties into a powerful financial weapon. Has moved more money than many Fintech that aspire to revolutionize the sector. The transformation. The change arrived in 2022 Thanks to an agreement with Mastercard. For the first time in its history, the card was the surroundings of the department stores to compete with the banks in neutral territory. The strategy is being a success. They maintain traditional advantages (interestless payments up to 60 days in ECI, 30 in other shops) but add functionalities Fintech: mobile application, notifications Pushcontrol of limits and geolocated promotions. The numbers. The total volume of the card reached 3,778 million euros in 2023, adding internal and external purchases. It is far from the 2018 record (4,895 million), but the new modality is growing. 1,372 million financed outside ECI in two years. Only 191 million in modality Revolving (Interest of 19.56% TAE). Free: without issuance or maintenance expenses. 4% bonus in Repsol for future purchases. The play. The English Court already had the largest loyalty clients in Spain. I just needed to open the doors. A much more interesting and advantageous play than the Fintech forced to find users from scratch. Yes, but. His proposal remains conservative. The revolving model barely represents 5% of the business, well below the standards Fintech. They prefer the safe margin of the interestless interest that monetize via cross consumption. The threat. For traditional banks, the English Court represents something worse than a Fintech Disruptive: a competitor with financial muscle, a huge customer base and brand credibility built for decades. Financiera El Corte Inglés, 51% controlled by Santander since 2013is the giant of consumption financing in Spain. In perspective. The chain has achieved what many financial startups only dream of: monetizing an existing user base without burning millions of euros in marketing. Its competitive advantage is not so much the technology and the confidence of 11.7 million Spaniards who already carry their card in the portfolio.

Tesla has launched in China a Model and L. It is the most Chinese (and logic) bet that could do in the short term

by

After months in which he has signed up for a Tesla Model and smallsomething cheaper to boost sales in Europe and press the competition for price, Tesla has surprised us with quite the opposite: a tesla model and longer. Only for China. And it makes all the meaning. The new Tesla Model Ylthat is, the elongated body version of the well -known electric SUV, increases the 150 millimeter wheelbase and its height in another 44 millimeters. A six -seater configuration is adopted (2+2+2) Therefore, a third row of seats is added that has been somewhat controversial. But it is also provided with heating and ventilation to the seats, electrical plates and integrated speakers. They are small improvements to increase the comfort of the passengers that are in tune with the bets of the L versions that the rivals usually offer in China. A category of vehicles that are based on three fundamental pillars: more space and more comfort for passengers. And that, curiously, they are transverse to all types of sizes. Purely Chinese With the presentation of Tesla Model YL, the opinions between criticism and public have been divided as usually happens with Elon Musk’s company. In Hybrids and electric They point out that some media qualify the third row like “going mounted in a convertible”given the little size between the head of the passenger and the roof. They ensure that the space that is free in the legs for a 1.70 -meter person is minimal and that it is an emergency solution for adults. In social networks a whole debate has been mounted following some images in which the same adult is seen sitting in the third row of seats. In one of them You see how it has a lot of free height between the head and the roof and ensures that it measures almost 1.90 meters. In another image it is observed as, with the trunk open, that same adult I would have serious problems traveling comfortably. Personally, I am inclined to think that the second option is the real but that does not mean that Tesla’s bet is bad. Yes, there are rivals that have a third row of more comfortable or practical seats. We have verified it in the Hyundai ioniq 9 or his brother, the KIA EV9. However, they are cars created from scratch with this intention in mind. Tesla is adding a third row of seats with a body L to improve the versatility of the car but, above all, with the intention of improving the comfort of the second row. That third row is an emergency solution and the really interesting is in a second row of a 2+2 configuration car with two good seats with all the comforts desired by a passenger. And in China the bodies L are usual. These cars are versions with longer bodies, with more wheelbase to generate a greater interior space. Europe has tired of selling this type of cars and Audi there, for example, demonstrates that the phenomenon is transverse to the size of the vehicle. The Germans have sold in China the Audi a3 l But also in those cars that, for European standards, already seem huge and do not need more interior space. Example? An Audi A8 L. To get an idea, this last car can exceed 5.19 meters to some endless 5.32 meters or impressive 5.45 meters. The latter refer to Audi A8 l horch. But the most interesting is in its interior seats with resting function or the possibility of adding a fridge in the central compartment, among other possibilities within the company’s customization program. Obviously, we talk here about a luxury car that Tesla does not intend to match but the company’s movement clearly points to proposing an experience in the cabin that is very sought in the Chinese car, transforming the interior into a kind of lounge with more space where feeling as comfortable as possible. Keep in mind that the great Chinese metropolis are huge and that the paths can languish for many minutes before the driver reaches his destination. This has made Chinese cars (and Europeans who want to sell there) have thrown into the arms of the screens and connectivity. But also that very wide rear seats are prioritized. Even sacrificing a good part of the trunk where Chinese cars tend to lose in front of the rivals. This happens because, despite its enormous sizes, in China the car is a Priority urban vehicle. It is rare that you travel with them since the distances are so long and the trains so competitive that either it is traveling in high speed or by plane. That is, cars are spaces with wheels where it is about giving the highest comfort to the client (another good example is the rise of their luxury minorities). And that is why the L -bodies L versions do not seek to have a third row of very comfortable seats. It is about prioritizing central seats in a 2+2+2 configuration and, in the best case, add a third emergency option. That is what Tesla has done.

Chatgpt now has a “router” that chooses for us what GPT-5 model use. And is choosing the cheapest

by

The launch of GPT-5 It has not been up to the expected. Instead of being surprised with the generational jump, too many people have missed GPT-4o warmth. Sam Altman, CEO of OpenAI, anticipated the launch of the New model with the death starbut the Hype It has stayed very far from the moments wow like the Chatgpt images generationthat reached “melter” servers. One of the culprits has a name: “router” or router. What happened. Behind him Model nomenclatures mess of OpenAI (already Remember Xiaom’s mobile messi) and the fact of making the user have to choose which one more, the company chose to launch all (sub) GPT-5 models in a unified way. Now the system would choose the model that estimated the most to resolve the indication. The person in charge of this task is a “router”. This, “quickly decides which model to use based on the type of conversation, complexity, or the need for tools.” The problem is that in these first days, the router usually opts too many times by the basic GPT-5 model, in front of the “Thinking” model or reasoner. What has made the new generation seen as much more silly than Sam Altman came to affirm (he defended it was like have a team of doctors at your disposal). The necessary jump It seemed impossibleand indeed, many users have not felt it. The problem. Openai decides which model is more efficient for the user, but also which model is more efficient for their servers. At the launch of GPT-5, they have not been transparent about what leads them to use one model or another, and users who accuse them of choosing the cheapest model for Save costs. Aidan McLaughlin, employee of Openai, defended in x that prefers GPT-5 without reasoning the majority (65%) of times for how interacts with the user. He assured that they do not use the routing to save costs, but use the one they think is the best model for each consultation, for efficiency. It seemed a successbut it has arrived without complying with what users expect. Altman recognized launch failures. During a question session (AMA) on Reddit held on Friday, Sam Altman read and observed that for many users, GPT-5 did not work as well as 4th. To it He replied That the new model seemed “more silly”, because the router did not work well when they threw it on Thursday. Who warns is not a traitor. On July 19, after announcing great performance in Mathematics OlympiadAltman announced that GPT-5 was just around the corner, in front of images like that of the death star, he was cautious, claiming to want to establish realistic expectations: “This is an experimental model that incorporates new research techniques that we will use in future models” “We believe you will love GPT-5, but we do not plan to launch a model with the gold capacity level of the mathematical Olympiad for many months.” The case remembers Sora’s, who was shown Very green After the Initial announcement promisesor that of O3, which was launched with a performance in benchmarks inferior to the initially promised (Unleashing everything A debate about whether we were already in the AGI). Openai has had to make changes. Before the complaints, from OpenAi they took a great measure: return to the users of the subscription Plus the possibility that the subscribers of the plan (of 20 euros per month) will use 4th again. But, in addition, they have touched the router to better choose the appropriate model to each consultation. Of course, without explaining what leads to use one or the other. The trick (if you pay). When users perceived that the problem of the new chatgpt with GPT-5 was not the model itself, but that the router did not turn to the reasoning model, they launched to look for ways to make GPT-5 Thinking use. The way to do it has been to integrate phrases such as “think about your in -depth response” in the indications, as suggested and demonstrated DOTCSV. In this way, it is achieved that, for Plus users, chatgpt use the Thinking model Without spending the quota of 200 weekly messages Manual mode. This trick does not apply to the free model, which could only activate it without asking for GPT-5 Thinking automatically once a day. Use free reasoning. Another change confirmed by Altman has been to integrate a reasoning button again (hidden) to use the reasoning model in the free version. Trying it, Chatgpt acknowledges using the GPT-5 Thinking Mini model, and we have been able to use it in 10 messages. From there, he used the model without reasoning. Is the successor of O4-miniwhich in April also received for free Reasoning functions With a “Think” button. Result: More use of reasoning. After announcing an increase in reasoning limits, Sam Altman has offered Specific data of the number of users who use reasoning now before the launch, and what indicates is the little that was used before, even among payment users. Free users have gone from less than 1% to 7%, but what the most collides is that those who paid the plus only used 7% reasoning, compared to 24% of now. It surprises in the sense that the reasoning of O1 and O3 supposed one of the great advantages over the free plan, thus the capacities of Deep Research.

Hundreds of people attended a funeral. All normal except because the deceased was an AI model that had been removed

by

The artificial intelligence boom is making us live moments of the most curious. There is people falling in love with an AIothers go to her as to a psychologist or for “Risheat” a loved one. What we needed to see was to celebrate a funeral for a retired model and it is just what happened a few days ago in San Francisco, where more than 200 people gathered to give the last goodbye to Claude 3 Sonnet. The deceased. July 21, Anthropic announced that he withdrew several modelsamong which was Claude 3 Sonnetprotagonist of this funeral picturesque. The model was announced in March 2024 and stood out for its balance between performance and efficiency. Together with him, Anthropic also withdrew Claude 1 and 2, in addition to confirming that Claude 3 Opus would disappear in January 2026. The funeral. It was held last Saturday in a warehouse in the Soma district of San Francisco and more than 200 people attended. They count on This Wired report that the decoration did not go unnoticed: a giant tentacle hanging from the ceiling and several mannequins with an aesthetic and represented different Claude models. In the center of the room he lay the mannequin that represented Claude 3 Sonnet and was surrounded by the most diverse offerings: from the classic flowers to a bottle of ranch sauce. Devotion. It sounds very absurd and clearly there was an aura of irony and humor in the event, but there were also emotional moments and even say in Wired that some attendees cried. Openai has the most popular chatbot, but Claude de Anthropic has a very devout fans community. The reason would be that Anthropic has managed to imbue a warm and friendly personality in his chatbot that has conquered many users. Exists a website where you can see ranking of the users who use Claude most and there are even people doing FAN ART With the company’s logo. Emotional connection Establishing affective links with a machine is not something new. In 1966 it was created Eliza, the first chatbotand many people who interacted with her ended up telling her personal things, as if she were another human, they called him the Eliza Effect. With the AI boom we are seeing how these links become popular and the success of apps such as Replika either Character.AI They are a clear example of this trend that increasingly adds more adherents. Attending the funeral of an AI sounds like a pretty fun plan to spend some time on the weekend, but developing an emotional connection with a chatbot is not always positive. The dark side. There are people whose connection with these chatbots brushes addiction to the point that Online support groups are being createdto alcoholics anonymous. In This study They analyzed how the use of chatbots affects our mental health and, although at the entrance it can have a positive effect, in the long run it is associated with higher levels of social isolation and emotional dependence. The experts alert of the risk of confusing the empathy of a machine with real empathy; A chatbot is always available to speak already It tells us what we want to hearThis causes a false sensation of empathy that can negatively affect our ability to connect with other human beings.

The best of the model is where it must always have been

by

GPT –4.1, GPT –4.5GPT-4.1-mini, O4-mini, O3, O3-PRO. If these names do not sound at all, you are not alone. Despite its popularity, a large part of the users of Chatgpt He never touched the model selector. Some knew that he was there, but beyond a brief description in the drop -down, few really understood what each one served. And yet they used it daily. Most likely, for months you have lived with the default base model –GPT -4Othe one Openai described as “ideal for most tasks” – without exploring anything else. Someone may ever try, just to discover that the results were not so different or that that was not what he was looking for. In the end, everything remained in the hands of a few advanced users, those who knew how to squeeze those other models to obtain better results. The model selector was a wall for many For a long time, using chatgpt meant making a decision that not everyone was prepared to take. What model choose? Which was better to program? And to write? What if I needed to analyze data? Openai offered a list, a brief and, hopeless description, some generic recommendation. But the only real way of understanding nuances was to experiment. Change model, try, compare results, change again. A process that demanded time and criteria. In an environment where we ask for immediate results, that was an invisible but real barrier. The majority stayed where he was. And the most curious thing is that even paying the subscription, many never used the options that were included. You don’t have to choose anymore. With the arrival of GPT –5, The model selector disappears for free users and loses relevance even among payment. Openai has designed a system that decides by the user: the new model knows when he has to think more and when he is not needed. If the task requires complex reasoning, GPT -5 takes it easy. If it is simple, respond instantly. The old chatgpt model selector, today already out of the scene This changes the rules of the game. Not only because it saves unnecessary time and decisions, but because it finally places intelligence where it should be from the beginning: at the user’s service, without having to know how it works inside. GPT -5 behaves more similar to us. Not because he is aware, much less, but because Start deciding in real time If a task requires thinking or not. As we do. When someone asks us a simple question, we answer quickly. When something demands analysis, we take a few more seconds. That is the logic that begins to replicate this model: if it takes effort, it applies it. If not, prioritize speed. GPT -5 behaves more similar to us In the background, that was what we expected of an advanced artificial intelligence. That understands us without giving technical instructions. That anticipates, That chooses by themselves how to help us better. That the model decides on your own does not mean that we have lost control. In fact, payment users can still manually force the type of response they want. From the chatgpt interface, the mode of reasoning with a button can be activated. But it can also be done with a simple instruction in the message: “Think about it”, “do it fast”, “give me a light answer” … the system interprets these phrases and adjust your behavior. It is a subtle, but important change. Because although GPT – 5 self -managed, It is still possible to intervene and refine experience. Whoever wants depth, can ask for it. Who wants immediacy, too. For those who use chatgpt intensively – at work, in studies, in complex tasks – this change has direct consequences. Before, a user could be paying for a tool that he did not understand at all, without knowing that he was using only part of his potential. Now, even if I don’t have time to experience or learn how everything works, GPT -5 does that job for him. Artificial intelligence finally begins to function as it should: offering the best without asking for explanations. And that means that those who did not know that they were losing productivity … can stop losing it. The difference between those who knew how to combine models and those who not, between those who explored each variant and those who stayed on the surface, have been reduced to minimums. From now on, the quality of experience will depend much more on how we ask for things that we know or not what a model to use. And that is good news, especially for those who never touched the selector. Users who, without changing anything in their way of interacting, They will start getting answers improves, more tight, more useful. GPT-5 equals them with the advanced ones without having to move a finger. GPT -5 does not add a new function. Correct an old incoherence. Until now, the most powerful system was hidden after technical decisions that few knew how to take. It is now in the foreground.

His model is not only powerful and free, but it has cost much less

Openai yesterday launched its first models with open weights since 2019: GPT-Oss-120B and GPT-Oss-20B. Two reasoning systems that mark a radical change in the company’s strategy after Deepseek R1’s success At the beginning of the year. Why is it important. Openai has gone from defending the safety of closed models to recognize that “it was on the wrong side of history” with open models. The earthquake that caused Deepseek In January he forced them to rethink their entire strategy. The context. Until now, Openai had kept all its models closed since GPT-2justifying it for security reasons. But rivals as a goal with Calls And especially Chinese companies with Depseek, Qwen and Kimi They have gained ground in the open ecosystem. The turning point came when Depseek R1 showed that it was possible to create advanced reasoning models with a fraction of the cost of Americans. Sam Altman then admitted that Openai needed “finding a different open source strategy.” And here it is. In figures: The major model, GPT-Oss-120bworks at a single 80 GB GPU with just 5,100 million active parameters of its 117,000 million total. His little brother, GPT-Oss-20bit can be executed in a laptop with 16 GB of memory (although the speed seems to be very slow with such a configuration, in the absence that we can try it more thoroughly). The current situation. The Benchmarks independent They place GPT-Oss-120b with a score of 58 in the intelligence indexsurpassing O3-mini but being below O3 and O4-mini. In competitive programming tasks it reaches 2622 points in Codeforces, while Depseek R1 achieves less score with a much heavier model. In detail. Architecture uses a system of Mix of experts (Moe, Mixture of experts) that activates only a fraction of the total parameters for each consultation. This allows the 120,000 million model of parameters to activate only 4.4% in each consultation, while the 20,000 million activates 17.2%. Both models maintain chain reasoning ability without direct supervision, following the principle that visible reasoning is necessary to detect undue behaviors. Yes, but. OpenAI has not made public training data, maintaining part of the secret. Nor does it include multimodal capabilities, limited only to text. Hallucinations are significantly higher than in their own models: 49% and 53% respectively compared to 16% of O1. Between the lines. This launch responds to both Chinese competitive pressure and the new Trump administration, which has urged US companies to release more technology to “promote the global adoption of aligned with American values.” The company has worked with partners such as Orange, Snowflake and AI Sweden for real use cases, seeking to validate whether the advantages justify continuing to invest in open models. Deepen. The models are available under Apache 2.0 license on platforms such as Hugging Facewith native support in tools such as Ollama, LM Studio and Services Cloud of the main suppliers. Openai has organized a network Teaming Challenge with $ 500,000 in prizes to identify security risks. This is OpenAi’s response to his Deepseek moment: recognizing that open innovation is not only inevitable, but necessary to stay competitive in a panorama where cost and accessibility matter as much as performance.

OpenAi has just kick the AI board. Your new model is free and can be downloaded to use from the laptop

by

Although his name suggests a certain vocation of technological opening, Openai had been moving away from that spirit for some time. From long before the launch of Chatgptin November 2022, the company did not publish an open weight model. In fact, it is the first open weight model since 2019 (GPT-2). That has just changed. This Tuesday, OpenAi has announced GPT-Ossan open weight model under Apache 2.0 license that can be downloaded for free and, in its small variant, run even in a laptop. A movement that nobody expected at all, especially since all eyes were put in Lat the imminent arrival of GPT-5. What is GPT-Oss? GPT-Oss is a language model developed by OpenAI, capable of understanding text instructions and generating answers with a high level of coherence, context and utility. It is a variant of the GPT family, the same technology that gave rise to Chatgpt, but with a key difference: its weights are open. That is, you can download it, run it on your own computer and adapt it to your needs. For the first time in years, OpenAI launches a powerful model that is not tied to its platform. You can use it without internet connection, without depending on your servers and freely to customize it. And besides, it is free. That opens the door for developers, small companies or even advanced users can experiment with AI in their own terms. What means that the weights are open? When we talk about the “pesos” of a model are open, we refer to the internal numerical values that you have learned during your training. They are, in essence, the knowledge of the model: what allows you to reason, write, translate or generate useful answers. That OpenAi has released those weights means that anyone can download them, analyze them and use them outside their servers. It is not the same as releasing the complete source code or the data with which it was trained, but it is an important step: it allows you to execute the model in own environments, adapt it to concrete tasks or integrate it into products without having to go through the Openai API. So is it a really “open” model? Now, the weights are open does not mean that the model is completely open. GPT -Oss is not Open Source strictly speaking: OpenAi has not published the data with which the model or the full code of the training process trained. What has released, as we say, is the final result, the parameters learned, under a permissive license (Apache 2.0). That is why we talk about an open weight model, not open source, According to the standards of organizations such as the Open Source Initiative (OSI). Can I use it on my computer? It depends on the model. GPT-Oss occurs in two versions: one of 120,000 million parameters and a lighter of 20,000 million. The most powerful version requires a GPU of at least 80 GB of memory (professional environments). The 20B version is much more accessible: it can be executed on computers with 16 GB of memory, which opens the door to use in personal portables and PCs. It is already compatible with tools such as LM Studio (which we have used to try Deepseek and other models)flame.CPP or VLLM, which allows you to try it at home without connecting to the cloud or depending on OpenAi. Of course, it is recommended to have some technical experience to put everything in motion. It is compatible with tools such as LM Studio, Llama.CPP or VLLM. Where do I download it? Is it really free? Weights are available for free download mainly in Hugging Faceand can also be deployed through platforms such as Azure, AWS or Databricks. The two variants, 120b and 20b, together with the necessary documentation are available. OpenAI publishes GPT-Oss under Apache 2.0 license, which means that you can use it, modify it and adapt it for commercial purposes. Do not pay for download or use it at home. If you choose to execute it in the cloud or on a payment infrastructure, the cost will depend on the supplier you use. Is it easy to use or do you have to have a certain level of knowledge? Using GPT-Oss is not as complicated as training a model from scratch, but it is not a solution that works with two clicks. The models include clear instructions and are integrated into platforms such as LM Studio or Llama.cpp, which allow them to be executed at local ease. That said, you will need to understand basic concepts such as execution environment, models loading and parameter configuration. If you have already worked with other open weight models, it will not cost you. If not, there are guides available, but you will have to devote some time to put it to function as it is. What can this model do? GPT-Oss is a multi-support model. You can reason, generate text, write code, answer questions, search for information and operate external tools, such as python browsers or interpreters. All this is also compatible with agents based on workflows, useful for more complex and automated tasks. Openai states that the 120B model achieves a proximity with O4-MINI in reasoning tests, while the 20B model offers similar results to O3-MINI in Common Benchmarks, with a good performance in programming, reasoning for steps and use of tools. It is not the most powerful model of the house, but one of the most versatile that can be used without paying or depending on your API.

How the South Korean aesthetic industry turned its beauty model into a global product

by

In The era of filters, Collagen capsules and “glass” promisesbeauty has ceased to be local. It is no longer enough to go to the trusted aestheticist or continue A ten steps routine in front of the mirror. Today, to reach the ideal of globalized aesthetic perfection, many take a flight. And the most wanted destiny is not Paris or Beverly Hills, but Seoul. A booming industry. South Korea has become the epicenter of beauty tourism, a global trend that not only transforms faces, but also cultural imaginary and economic figures. In a report for The Timesmore than one million medical tourists traveled to South Korea in 2024, according to data from the Ministry of Health and Welfare. 68 % did so specifically to undergo aesthetic procedures, whether plastic surgery or dermatological treatments. And the sector does not stop growing. According to Grand View Researchthe South Korean aesthetic industry – valued at 2.4 billion dollars in 2024 – could exceed 6,300 million in 2030, promoted by international demand and advances in aesthetic technology. An experience “everything in one”. As They have detailed in The TimesGangnam district clinics-yes, the same PSY’s global hit-offer these types of experiences with packages that include 3D facial scanners, hyperbaric oxygen therapy, intravenous sera, microwave treatments to sculpt the face and even functional desserts such as pumpkin purés for post-treatment recovery. The British influencer and doctor Ewoma Ukeleghe shared in The Times Your experience: six treatments in one day, among them they rejure (An injection of salmon DNA) and Lifting wave. The promise of perfection. This boom is not accidental. As We already wrote in Xatakathe phenomenon feeds on multiple factors: the global impact of K-Pop and K-Drams, the Tiktok virality of products such as the Sheet Masks or the Korean tonic, and the rise of star ingredients such as collagen. Korean beauty not only offers visible results, but also an aspirational aesthetic wrapped in ritual, pop and science culture. However, there is also a dark side. As Dr. Christine Hall warns In The TimesIn South Korea there is an intense social pressure to maintain an impeccable image. “Presenting the best version of oneself is a sign of respect for others,” he explains. This logic, which may seem positive on the surface, encourages an extreme culture of perfectionism that, over time, can generate significant psychological impacts: from anxiety related to appearance to dependence on aesthetic treatments to sustain self -esteem. Unequal attention. Despite its international success, the system is not fully adapted to the foreign tourist. Although many clinics have personnel who speak English, others still depend on automatic translators such as Google Translate. In the Times report They tell the story of Ukeleghe, who reported how a nurse approached with an injection without explaining what it was; She, being a medical one, understood that it was a corticosteroid. But a patient without knowledge could have panicked. In addition, there is a real lack of attention to ethnic diversity. As experts in Byrdie point outNot all clinics have experience in working with skin tones other than Asia. This can lead to unexpected results, especially in laser or pigmentation treatments. The new Türkiye? The phenomenon reminds the boom of aesthetic surgeries in Türkiye or Colombia. In 2022, the British Association of Aesthetic Plastic Armegoons reported a 35% increase in complications among British patients who traveled to Türkiye for procedures such as liposuctions or implants, According to The Times. On the other hand, in Colombia, procedures such as the “360 liposculpture” or the increase in buttocks achieved such popularity that they attracted tourism from whole countries, although they were also subject to research for deaths and bad praxis, As The New York Times reported. And South Korea is not exempt from risks. During his visit, Ukeleghe rejected sedation precisely for not being clear about the presence of an anesthetist in case of emergency. In social networks, a viral video circulated – then eliminated – in which an American woman denounced having lost vision in an eye after a complication with Juvenlook, one of the most popular treatments in Korea. Although the case was not officially verified, the event generated concern and debate. In addition, Dr. Hall warns of “factory” clinics that apply treatments with just minutes of previous evaluation, reducing costs at the expense of security. The pressure of not aging. The rise of collagen as a magical solution for youth is no stranger to this ecosystem. As we wrote in Xatakahas become a symbol of self -care, but also of aesthetic anxiety. Although some studies point to mild benefits in elasticity or joint health, many are funded by the brands themselves. Even so, marketing insists: hydrolyzed, vegetable collagen, peptides, exosomes … Everything is sold as the new elixir. But perhaps the problem is not in the ingredients, but in a society that penalizes any trace of the passage of time, especially in women. The female social and professional invisibility when aging is not a myth: it is documented. More, less scalpel. The next border of Korean beauty tourism is marked by artificial intelligence and extreme customization. According to Byrdietreatments created from genetic analysis, facial scans and aging prediction algorithms are expected. Beauty becomes not only attainable, but calculable. A symptom that goes further. In this context, it may be worth asking if the real challenge is not in technology, but in ideal. In other words, perhaps the collagen is not the elixir of youth, but the reflection of a society that seeks to stop the clock at all costs. Dr. Hall emphasizes that the aesthetic innovation in Korea advances at such a speed that some treatments that promise to be revolutionaries end up disappearing before consolidating or even arriving in Europe. What today is a trend, tomorrow can be obsolete. Meanwhile, the clinics are still full, the flights to Seoul are sold as an investment in oneself and the hashtags like #kbeeautytrip do not stop accumulating millions of visualizations. Perhaps the real challenge is not to soften … Read more
