Spotify is dealing with an avalanche of songs made with AI. So you have decided to react to mark the limits

by

You open Spotify, you run with a song that you cannot stop listening and, nevertheless, the name of the “artist” sounds at all. You wonder if there is a band behind or if it is a Track generated by AIand the doubt is not trivial: the trained ear may detect it, but for millions of listeners the border has become blurred. With generators like Suno either You raising their creation quality, catalogs are filled and the context matters. This week, Spotify announced New policies to stop three fronts: “Slop”, impersonations and transparency on the use of AI. The company states that it wants to protect artists and prevent the public from feeling deceived, without prohibiting responsible use of these tools. In just a few months, music generators have become accessible tools capable of producing thousands of subjects ready to be uploaded to streaming platforms. We do not talk about master compositions, but about songs that meet the minimum to sneak into mass catalogs. The result is an avalanche that makes it difficult to distinguish between genuine proposals and simple algorithmic exercises. For stamps and artists, this saturation not only generates confusion among listeners, it also threatens to dilute income in a system where each reproduction counts to distribute royalties. Spotify’s plan against music made with AI Spotify frames its new rules in a simple idea: music has always been crossed by technology, from the multipist tapes to auto-tune. The current difference is that artificial intelligence evolves at a speed that generates uncertainty. In this scenario, the platform states that it wants to reinforce transparency and shield the confidence of listeners, while respecting the freedom of artists to decide how to incorporate these tools into their creative process. One of the most sensitive spotlights for Spotify is the impersonation of identity. The company has hardened its rules and clarifies that it will not allow songs that reproduce the voice of an artist without its explicit authorization. This includes voice clones generated with artificial intelligence, “Deepfakes” and any unauthorized vocal replica. In addition, new measures are tested with distributors to prevent music from foreign profiles, an increasingly common attack. The objective is that musicians can denounce quickly and maintain control over their own artistic identity. Another front that the platform wants to stop is spam. Spotify explains that some users try to manipulate the system by uploading songs of just 30 seconds to accumulate reproductions with Right to paymentor repeating the same theme with minimal changes in metadata. To combat it, in the coming months will deploy a filter that will identify this type of practices and stop recommending them. The company ensures that the measure is necessary to protect the distribution of royalties and remember that in the last 12 months it eliminated 75 million fraudulent tracks. The third leg of the plan is transparency. Spotify collaborates with DDEX, the agency responsible for setting standards in the music industry, to create a metadata system that reflects the role of AI in each song. The objective is that the credits indicate if artificial intelligence has been used in the voice, in the instruments or in the production, so that the listener knows clearly. As reported by the company, 15 seals and distributors have already promised to adopt this standard, although for now there is no release date. The real impact of the new rules will be measured over time. For artists, reinforcement against impersonation and spam can translate into a fairer environment to compete for attention and royalties. For listeners, promise is a clearer experiencewith credits that allow distinguishing which part of a song has been generated by Ia. Even so, there is uncertainty about its scope: from the possibility of errors in automatic detection to the difficulty that stamps and distributors adapt their processes quickly and homogeneously. Spotify will probably continue working after this announcement. The effectiveness of the filters and the adoption of the new credits will depend on the industry as a whole move in the same direction. AI will continue to evolve and new methods are likely to make control systems. In that scenario, the company will have to demonstrate that its measures not only slow the abuses, but also help maintain the confidence of the listeners and the value of artists’ work.

These are the limits of use of Google’s artificial intelligence in its free and payment version

by

Let’s tell you What are Gemini’s limits announced by Google itself. With this, you can know how much you can use each of the functions depending on whether you are using a free version of Gemini or if you opt for any of the payment. Thus, you can know from the requests to Gemini 2.5 Pro that you can make up to date to the research reports thoroughly or the generation and Image editionbecause the number of times you can do everything depends on the version you have on this artificial intelligence. These are Gemini’s limits Free gemini Gemini with Google Ai Pro Gemini with Google Ai Ultra Use of model 2.5 Pro Up to 5 requests per day Up to 100 requests per day. Up to 500 requests per day.

Nor will you receive new functions as soon as you will do if you have a payment version. But there is also good news, and it is that Google is very generous with the generation and editing of images. Free AI users can create or edit up to 100 images a day, which gives a lot of room to play with those functions in which Gemini stands out. For the rest, as expected, the free version has less context tokens, that is, it has less capacity to remember things when it comes to responding to you, although it has enough for most tasks. Audio summaries are the same for all platforms. In Xataka Basics | Gemini Image Editor: 16 forms and tricks to squeeze Nano-Banana with Google’s artificial intelligence

a cheese so extreme in its preparation that the European Union had to put limits

by

Few more fascinating things for the human being than that indicated as “forbidden” and “dangerous.” If we also talk about a gastronomic product that comes with the Italian seal and that after it there are hundreds of myths and legends, we have the breeding ground to raise the product to the object of worship for the most exquisite and adventurous palates. There are many good cheese storiesbut none like that of most dangerous cheese in the world and its maturation process. Casu Marzu. The truth is that cheese is, in essence, fermented and aging milk. It happens that the process goes through controls to achieve adequate balance between bacterial activity and the quality and taste of cheese. The variety in this process and the different traditional approaches to elaborate it is what makes us have so many types. Yet, None approaches the Casu Marzu processwhose translation already gives us a track, “rotten cheese.” This Italian cheese from Sardinia has a peculiarity. It is created with the help of very special worms or larvae, creatures that remain alive during the maturation and fermentation process and, most importantly, when we open it to taste it. So, it is time to close your eyes and expect the portion not to reach the mouth with a living larva. The fly and cheese. It We count a long time ago And it serves to give context to the story of Casu Marzu. Humans have been eating dairy products like cheese almost 6,000 years and, in essence, we owe everything to a fly. And it is that the fermentation process, key in the delicacy, occurred first thanks to the role played by the fruit fly. Apparently, the casual encounter between the insect and a cube of fresh milk flowed into a new type of yeast thanks to which raw milk became a different organic compound. The mixture of two different substances and yeasts worked the miracle. However, already a difference from most fermentation processes of cheeses, Casu Marzu has a more “narrow” relationship with the fruit fly. Very active larvae. The larvae come from the Piophila Casei cheese fly. Always in motion, they are able to jump up to 15 centimeters in the air. In fact, it is considered harmful in food industries. The contradiction is given because as an detritivorous, it can be very useful in forensic investigations and, for cheese addicts, they are fundamental for the creation of Casu Marzu. Fermentation process. The cheesers begin the process of the famous delicacy by cutting a small hole in a sheep milk cheese wheel and leaving it outside, maturing. Flies (the Piophila Casei) make their appearance and enter the opening to put their eggs. Once the larvae hatch inside, their excretions decompose the fats and proteins of the cheese, creating a gentle and creamy texture. At this point, when a sticky liquid known as tears is filtered through the peel, the cheese is “at its point” ready to eat. The resulting delicacy is spicy and penetrating flavorsimilar to maturo gorgonzola, with an acid touch that leaves the trail of the larvae. Finally and not least, to know if we are facing the true Casu Marzu we must make a clean cut, if we find a mass of worms that twist, everything is going well. Cream of Casu Marzu Danger: myiasis. If we ignore the larvae, the creamy piece of cheese may seem tempting. In fact, it is for many adventurers. However, we must, approach the piece with some caution. As The Science of Cheese points out“The worms that jump cheese are able to do it a few centimeters, so consumers are recommended to protect the eyes” when the wheel opens. More risks. If by chance we end up engulfing any of these living larvae, there is another danger. According to the University of FloridaThey are often cited as one of the most likely causes of intestinal myiasis. This condition, certainly disgusting, occurs basically when the worms are installed in our digestive system. There, in our intestine, they make “mischief.” “Intestinal myiasis occurs when eggs or fly larvae previously deposited in food are ingested and survived in the gastrointestinal tract,” They explain the centers for disease control and prevention. “Some infested patients have been asymptomatic; others have had abdominal pain, vomiting and diarrhea.” The most dangerous. For all this, the appellation is not trivial. The marzu casu that contains larva It is enjoyed for thousands of years in Sardinia. Cheese, prohibited in many parts of Europe, can reach really high prices. In Sardinia the kilo can be found for more than 50 euros. The trick to ingest it. By the way, there is a formula in the event that you want to taste a piece of cheese with the greatest assurances. Yes, many people take risks and eat live worms, but alternately, They can be crushed to kill them and then spread the cheese About bread. We can also seal a piece in a plastic bag with closure. When the sound of worms stops, it is time for tasting. And if it doesn’t even convince you, you can always go to the super or to the market and ask for the cheese that you like so much and that does not bring surprises.

A Chinese firm has just presented a quadruped that challenges the limits. Boston Dynamics no longer has a clear path

by

In a world where the focus seems to be in humanoids as Tesla optimus or the ‘nurse’ robot that already works in a Taiwan hospitala new generation of machines is winning its place. They are fast, resistant and are beginning to show that they can do much more than impress in videos. One of them has just run 100 meters as if their future depended on it, and is Chinese. Quadruped robots also compete. For years, the conversation about advanced robotics has been monopolized by biped figures. Robots that move as humans. But there is another way: that of robots that do not try to imitate us, but overcome ourselves in other areas. The quadrupeds, for example, have been demonstrating its usefulness in difficult terrain, repetitive tasks and, now also, in speed tests. A challenging career. It was just a moment, but it didn’t go unnoticed. How global aims aimduring a live broadcast of Chinese state television, a four -legged robot aligned on an athletic track prepared for something unusual: a 100 -meter race. When the stopwatch was launched, Black Panther II did, the new robot developed by the startup Mirror Me. He completed the route in 13.17 seconds, which is equivalent to an average speed of 7.6 m/s. In that same test, the robot sensors registered a peak of 9.7 m/s, and the company claims to have reached 10.9 m/s in previous internal tests. If that data is confirmed, we would be facing one of the fastest quadrupeds. Is it the fastest in the world? It depends on how you look. The figures invite to breastfeed, but it is always key to put them in context. Black Panther II reached 10.9 m/s in an internal test, which is equivalent to about 39.2 km/h. During the televised race, the registered peak was 9.7 m/s (34.9 km/h). Both figures exceed the official Wildcat,That according to the Boston Dynamics website reaches 30.6 km/h. For its part, the robot Cheetah – also from Boston Dynamics – reached 45.6 km/h (12.6 m/s) In laboratory tests. The demonstration, collected in an official video, was made on a running tape with external food and physical support to maintain balance. Even so, the data remains the highest technical reference registered by a quadruped. With that data, Black Panther II would be below the Cheetah – at least in tip speed – but clearly above Wildcat. In other words: it is one of the fastest quadrupeds ever built, although its brands have not yet been officially certified. For now, the formal title is maintained by the Hound robot, of the Advanced Institute of Science and Technology of Korea, which completed 100 meters in 19.87 seconds (about 18 km/h), As stated in the Guinness book. A young startup with very clear ideas. Mirror’s story didn’t start a long time ago. The company was founded in May 2024 in Shanghai by a group of professors and graduates from the University of Zhejiang. One of the founders is Jin Yongbin, a researcher at the Institute of Innovation in Humanoid Robots, while his partner, Wang Hongtao, is a university professor with trajectory in advanced robotics. In just one year, this startup has gone from developing robotic arms and mechanical hands to compete publicly with companies such as Boston Dynamics. Beyond the Black Panther II, Mirror already works on new prototypes. Among them, a fast bipedo in 2026 and a humanoid that, according to their plans, could act as a personal assistant for the year 2030.

First the AI ​​wanted us to pay for its quality. Now we want us to pay for the right to use it without limits

by

Everything is invented, they say. The Freemium model It is a good proof of this: it is common for a long time that we can play video games or use free software applications. But of course, they are not the complete versions, but basic and capadas editions. So you can keep taking advantage of them if you don’t need anymore, but the opposite The problem beginsbecause it has to go through the box. That is just what we are living With the world of AI. Almost all models allowed us to use them for free. It was what happened with Chatgpt, Gemini, Copilot or Claude. Over time the companies responsible for developing these models were launching more powerful and higher quality versions, but if you wanted to use them, I had to pay. Chatgpt plus, Claude Pro either COPILOT PRO They marked the guideline with subscriptions of $ 20 per month that gave access to more intensive uses and also to those most advanced models and characteristics. But that was not enough, and Openai announced the Chatgpt Pro launch In December 2024. It was an even more advanced and perfect alternative for intensive users, but its price also raised an important barrier, because not everyone is willing to pay $ a month for using AI models. That plan may seem expensive if you do not take advantage of it, but what happens if you take out all the juice? It may then become an aid that allows you to do more in less time, and if so, those 200 dollars may seem to a bargain: it depends on each situation, and OpenAi knows it. So much so that he states that in the future there will be hyperspecialized chatbots that 20,000 euros will cost per month. It looks like an absurd figure, but what if you use them generate 40,000, 50,000 or 100,000 euros per month? There is the key: if you take advantage of those models intensively and if they really compensate. And that’s where companies have realized that they can charge Not only for quality, but for the quantity. This is what Anthropic also proposes, which these days announced his new Claude Max plans with two variants. The first, 90 euros per month, which allows limits of use five times higher than those of Claude Pro (the anthropic chatgpt plus, which costs 15 euros month). The second, 180 euros per month, which goes further and allows you to use this chatbot with more broad limits. What does that mean? Basically, even being an intensive user it will be very difficult for the feared message to appear “you have exhausted the request of requests, wait a few hours to use it again.” It is not that the model is better or faster – at least, for now. You can simply use it much more. And if you want more, nothing happens: there is the API Anthropic’s strategy, such as Openai before, is logical and reasonable: if you want to “abuse” the advantages of AI and make intensive use of its capacity, you will have to pay an extra. There is one more alternative in these areas, and that is that of Pay for the use of the API: Here we can consume as much as we want, and the payment for use is measured at cost per million input or output tokens. If the model is more modern and capable, you pay more. If it is older and modest, less. In Anthropic, for example, Claude 3.7 Sonnet (its best model currently) costs three dollars per million entry tokens and $ 15 per million output tokens. The previous version, Claude 3.5 Haiku, costs $ 0.8 per million input tokens and $ 4 per million departure tokens. With the payment model for use raised by the APIs, very directed to developers and companies – and especially useful for programmers – there are also great differences between some suppliers and others. The O1-PRO model of Chatgpt Pro is for example 140 times more expensive at its cost of API that the O3-mini that is available in Chatgpt. What is clear is that companies have already profiled how we are going to pay to use artificial intelligence. We will not only pay for the one that is more advanced; If we want to use it a lot, it will touch more. Here there is a danger that companies play with those limits and “Redoublacionen”but we will cross that bridge when we get to it. At the moment one thing is clear: using the AI ​​can leave for free, but if you want to use it a lot and well, go preparing the wallet.

Without tolls, the AP-7 has become hell. The solution passes through speed limits of 60 km/h

by

The AP-7 is known as the Mediterranean highway. It is an essential axis for Spanish traffic since it allows to circulate without interruptions between Tarragona and Alicante. And if we add their links to other roads, it allows to circulate between France and Cádiz. A road, yes, that until 2021 was marked by various tolls. Some sections, in fact, They were one of the most expensive in Spain. The road, however, is fought from the Tolls in 2021. What it was A historical claim In the area it soon became a problem. In its first year, the road saw tourism traffic increasing 40% and 80% of trucks, collected in The country. The obvious result: more jams, more accidents … and more jams accordingly. Specifically, only the first year the AP-7 concentrated 20% of the dead on the road throughout Catalonia. A figure that contrasts with the trend of the rest of the country where the deceased on the road They concentrate on secondary roads. The New free routewith France at one end and Barcelona to one of its sides, it has turned the road into a parade of merchandise vehicles. And the problem is such that since then solutions are being sought. First with a partial reduction of speed limits. An action that has arrived in 2022 and added 82 kilometers. The next step is to copy Europe. A solution to the European Since then, the AP-7 situation has not improved much. Although mortal figures have been reduced over time, only in 2024 more than 1,600 incidents on the road. The response of traffic managers has been to reduce speed. How much? It will depend on the Meteorology and traffic congestion. Because the proposal goes through a changing management of the maximum speed of the road. A solution that already applies to other roads in Europe and that can reduce the maximum allowed limit to 60 km/h. The person in charge of announcing the measure was the Minister of Interior, Núria Parlon. They point out in The newspaper that this section of variable speed will extend for 150 kilometers between Maçanet de la Selva (Girona) and the Vendrell (Tarragona). For this, panels controlled by artificial intelligence will be implemented that will limit the traffic speed based on the different circumstances that are giving. The measure takes as reference what happens, for example, In German autobahn. On these roads there is no defined speed limit. In fact, if circumstances accompany, There is no speed limit. But at nightfall, when it rains or if there are works on the road, the panels show a speed limit equal to or less than 130 km/h. The operation is exactly the same as on the German roads but the director of the Catalan Traffic Service (SCT), Ramon Lamiel, already warns in an interview with EFE: The speed can be reduced up to 60 km/h at some points. At the moment, the project is in the development phase by the Servei Català de Trànsit (SCT)who has the competitions on Catalan roads. In the second quarter of the year it should be written to be able to get it as a tender. They explain in The countrythat the intention is to deploy a progressive reduction in the maximum speed before the driver is suddenly with a bottling that forces him to reduce the speed much more drastic. Speaking to the newspaper, Lamiel insists that speed will be reduced Only in the most congested sections since they believe that the increase in accidents is derived from a greater volume of traffic and not from the danger of the road. In addition, he points out that they already proposed this measure to extend it nationwide by the roads that are the competence of the DGT but that its proposal was dismissed. The truth is that The theory says that when we circulate more slowly, traffic jams are reduced. Atasco are a sum of errors. When we circulate at a lower speed, the time to alleviate errors is greater and these are reduced. It is a matter of effectiveness and not so much speed. Traffic circulates more slowly but flows. If we circulate too fast, the braking are more abrupt, it costs more to recover a sustained speed and, little by little, we end up stucking the road.
