Their models not only perform just as well but are much cheaper

Sometimes it is difficult to keep up with the innovations that artificial intelligence is leaving us. However, it is also a good sign that there is voracious competition and that, even if we thought that companies like OpenAI or Google had every chance of completely dominating this sector, not all the fish has been sold yet. And what began as a race to create the most powerful models has become a battle to deliver the best performance at the lowest possible cost. And in this new competition, China leads. Change of third. For years, the conversation in AI focused solely on which model was more capable: who passed more benchmarks, who solved more complex problems, who generated better answers. But that phase is being relegated by another in which price is once again a determining factor in making decisions. This transition marks a turning point, since it is mainly Chinese startups that are demonstrating remarkable ability to produce powerful and extraordinarily economical models. Qwen leads the revolution. As Kai Williams highlights in the ‘Understanding AI’ newsletterAlibaba’s open model ecosystem, known as qwenhas become the most downloaded model family in the world, according to Hugging Face data analyzed by the ATOM Project. “Qwen alone is roughly matching the entire US ecosystem of open models today,” counted Nathan Lambert, researcher at the Allen Institute for Artificial Intelligence, at the PyTorch conference. The Chinese company has achieved something that seemed difficult: create competitive models in practically all sizes, from small to 235,000 million parameters, offering options for any business need. Real business adoption. In addition to the technical figures of their models, the use cases also deserve special mention. In October, Brian Chesky, CEO of Airbnb, caused a bit of a stir stating that his company “relies a lot on Alibaba’s Qwen model” because it is fast, cheap and powerful enough. This statement is interesting because of the context, since we are talking about a top American company preferring to use an open Chinese model, something that is powerful enough to change the perception of the industry. Williams points out in the text that, in addition to Airbnb, there are also other companies that would prefer to adopt Qwen’s models, but for reasons of image or regulatory compliance, they cannot. Mainly because they are models from China. And that could be the great barrier for Qwen and the rest of the Chinese models that would make its adoption difficult. So Chinese startups have a big job ahead of them to try to change that perception in an increasingly complicated geopolitical context. Kimi K2 gave the surprise. If Qwen dominates through volume and versatility, Kimi K2 Thinking It stands out for being possibly the best open model in the world in terms of benchmark test scores. Just like share Williams in the newsletter, Artificial Analysis currently ranks it as the most powerful model not created by OpenAI, Google or Anthropic. DeepSeek and the domino effect. The launch of DeepSeek R1 in January was the catalyst that unleashed this wave. It arrived just four months after OpenAI announced your first reasoning model, o1but with a crucial difference: DeepSeek openly published the model parameters. The noise was such that even the DeepSeek app briefly surpassed ChatGPT as the most downloaded app in the iOS App Store, Nvidia shares fell almost 20% days later, and Chinese companies rushed to integrate the model into their products. Today we are still waiting for DeepSeek to speak again with its next deep reasoning model, about which not much is known yet. On the other side, putting out fires. The United States has not sat idly by. When it comes to open weight models, OpenAI launched theirs in AugustIBM published its Granite 4 models in October, and Google, Microsoft, Nvidia and the Allen Institute for AI have also introduced new ‘semi-open’ models this year. But none have reached the level of the main Chinese open models. Lambert, who has led efforts to advance a new generation of American open models, acknowledges that progress has been slow and the gap is widening. Everything indicates that 2026 will be decisive in determining the pace of adoption by companies and, above all, in determining the choice of model in an increasingly immense ocean.

Esnifar caffeine has become a tool to perform better. Science is not sure if it is safe

One of the chemical compounds that coffee is is caffeine, and for years It has been subject to numerous myths. It is something that contributed to coffee to earn a certain bad reputation, but numerous studies In recent years they have helped us Understand coffee properties and the Effects of caffeine on the body. Moreover: caffeine has gained popularity as a supplement, so much that it is sold separately in the form of gum or strips. And yes, also in the form of caffeine dust to sniff. Coffee as a supplement. Like almost everything, caffeine has both positive and negative effects. Take coffee or food with caffeine in sleep times, It is not the best decisionbut as a sports supplement, caffeine has proven to be an ally. In certain situations, at least. For example: due to your effect In oxidation of fats, consume caffeine stimulates ‘fat burning’. In team sports such as football, An experiment demonstrated that players who took a dose of caffeine before training made more precise long passes. However, this study presented the counterpart Of the caffeine: when the player had to face situations of stress and thought very fast, as usually happens during a game, decision -making was something worse among those who had consumed caffeine. Therefore, it depends on the sport we do and our goal, but in what can be an individual strength and aerobic training, caffeine has certain effects that we can consider beneficial. One more supplement, go. Cocaffeine. However, caffeine is not only consumed to perform better at the sports level. There are students, drivers or people who simply need it at certain times of the day to feel more awake thanks to their stimulating effectand that is where products that do not seek to provide any more than the amount of caffeine enter. We don’t talk about energy drinks (With huge amounts of caffeine per can, yes, but also a lot of sugar), but of bars, gels, gum (used in the Military scope), pills and even caffeine aerosols. The key here is speed. While having tea or coffee causes caffeine to take half an hour to take effect, with liquid caffeine roads, gels or caffeine patches that dissolve in the mouth, the effects are much faster. There are already those who are offering both mouth and nasal aerosols that seek to activate sensors in the brain or a direct route for absorption in the lungs. The problem? There is no scientific evidence, for the moment, that supports these statements, but there is one more method. Energy sniff. In the image we can see the presentation of ‘Widkraut Energy sniff’, a product that clearly alludes to certain substances. That mountain of white dust or the product name itself is a clear wink. “A widkraut boat contains more than 20 doses of energy,” We read on the webwhere it is also detailed that it does not have tobacco, nicotine or sugar; which is driven by nature and has been clinically tested. Your uses? Work concentrated for longer, endure night shifts or long trips by car, gaming, party nights or pay more in studio and sports sessions. Has a lot of ingredients Different apart from caffeine and claim that, thanks to scientific confirmations by “three clinical studies elaborated by the German Institute most recognized in dermatological studies”, it is safe for the nasal mucosa. Because Energy Sniff, like caffeine aerosols, is consumed by the nose, but in this case, the dust is snorted. Careful. The 60 rations cost 48 euros, similar what costs a kilo of good coffee with more health propertiesbut what is sought here is, as we said, that caffeine arrives as quickly as possible to the bloodstream to begin to circulate through the body causing the desired effects. Returning to Energy Sniff, they clarify that it is harmful in case of ingestion and should only sniff, never exceeding the maximum dose of one gram. There are already studies that They point that these alternative ways of consuming caffeine are not entirely supported by evidence and that more information and analysis is needed. For example, bars and gels are under the magnifying glass to see what real effects they have on athletes, but as we say, it continues to investigate. About sniffing caffeine, it must be clarified that, although the brands (there are others, such as’Want a bump?‘ either ‘WP Energy sniff‘that are promoted the same) They clarify that everything is manufactured using legal ingredientsThey have caused some arqueen an eyebrow. And doctors? That lack of prolonged and conscientious scientific support on the effects not only of caffeine itself, but of the way of taking it to our body, since you have to be careful not to overcome the recommended caffeine doses (special attention in pregnant women) and stop taking it by this way if we feel any discomfort. At the moment, the investigation is focusing In gels, gum and bars as a useful strategy to assimilate caffeine in the shortest possible time. On the other hand, there are doctors who have spoken about it. Shaline Rao is the director of Cardiology at Langone Hospital in Long Island and Comment The aforementioned: “The key is to keep the amount safe and take into account the upper limit to avoid overdose, as well as the appropriate time between them.” Other voices are more criticismreferring to the ease of passing with the amount of caffeine, the possible development of tolerance that leads to increase the dose little by little harmful effects in the mucosa. For the American FDA, directlyconcentrated caffeine products are “a serious threat to public health” and in France, directly, His sale was prohibited In 2024. Viewing the boom in this form of consumption, it is now on the roof of science to check the risks and if it is worth against aerosols, gels or gum.

that the cloud can perform as an RTX 5080

Nvidia does not want to convince you that the cloud is the future. You want you to forget that you are playing in the cloud. That is the real promise behind the technical jump that just announced for Geforce Now: to offer a game experience that gives up as a RTX 5080but Without having an RTX 5080 in front. And they raise it without nuances. According to Nvidia, the new Blackwell hardware that feeds its servers is designed to reach that bar, with the declared intention to match and even overcome, in certain scenarios, local systems. The announcement comes as a logical continuation of the movement that Nvidia made in early 2023, When he incorporated the overpods 4080 and gave the first big leap of quality to the cloud game. This time the bet goes further: according to the company, the new Blackwell hardware allows to reach a 30% higher than the previous generation, with support for resolutions up to 5K at 60 fps or 1440p at 240 fps. Everything is part of the same long -term plan: demonstrate that the remote game can match or overcome a physical team. According to Nvidia, what he proposes is not only more gross power, but a rethinking of how the game is built remotely. The new superpod does not replicate a specific card: integrates multiple elements that, combined, emulate the performance that is today associated with an RTX 5080. That power is distributed between Blackwell architecture GPU, Optimized servers for ultrabaja latency and an infrastructure that seeks to prioritize consistency. The goal is that this fluidity does not depend on the player’s team, but on the muscle in the data center. One of the most tangible improvements is what Nvidia calls “Cinematic Quality Streaming.” According to the company, this modality allows to reproduce more complex textures and conserve the detail even in dark areas or in distant elements of the stage, two points especially demanding for games streaming. Behind this improvement, Nvidia points out an update of the coding chain and video delivery, along with technologies such as Rivermax HW Packet Pacing, which better manage data sending to avoid peaks. One of the keys to this new stage of GeForce Now is that it is not limited to the desktop PC. The performance jump also reaches devices such as Steam Deckwhere the native app passes from 60 to 90 fps thanks to servers with RTX 5080. In parallel, compatible LG televisions become the first in the world to offer streaming to 4K and 120 Hz with HDR from the native app. In addition, the brand’s OLED monitors can reach resolutions of up to 5K when connecting through Windows or MacOS, without the need for additional hardware. Nvidia has made it clear that this Geforce Now update does not revolve around the number of available titles. The catalog will continue to grow, but the focus is in quality: at the time of launch, there will be 20 games optimized specifically for this new type 5080 configuration. According to the company, new optimizations will be added every week. DLSS 4 and Reflection play a central role here: they are the tools that allow adjusting the cloud performance so that the fluidity and the response are as close as possible to a well -tuned local system. The company has confirmed that the update will begin to be deployed in September, without exact day or detailed regional calendar for now. The company Keep the current service rates: GeForce Now Ultimate will follow $ 19.99 per month or $ 99.99 for six months, and the Performance Plan at $ 9.99 or $ 49.99 for six months; There will also be daily, monthly and annual options to the launch. Nvidia argues that the arrival of the Blackwell architecture places GeForce Now in a stretch of performance that, in concrete scenarios, can match or overcome local equipment: the official note quotes 62 Compute Teraflops on the Ultimate Servers and a 48 GB frame frame, in addition to improvements that, according to the company, multiply the performance of the previous generation and exceed the Play In several metrics. That promise, presumably, will depend on external factors: the available server and the quality of the user connection.
