Your AI advantage is evaporating

Chinese AI companies are throwing it away. After the launch of the promising Kimi K3, now Alibaba has just introduce Qwen 3.8a gigantic model that according to those responsible is so powerful that only Fable 5 manages to surpass it. If that is confirmed, we will be facing a potential turning point in the AI ​​race. One in which China will no longer be months away. A fearsome rival for GPT-5.6 and Fable 5. Qwen 3.8 Mac has 2.4 trillion parameters, placing it only “slightly” behind the also gigantic Kimi K3 which we learned about last week and which has 2.8 billion parameters. Developers can now begin testing the model through Alibaba’s Qoder programming platform, and those responsible for it have announced that they will release their weights soon. Alibaba’s message is quite a challenge, because they claim that only Fable 5 manages to exceed their capacity. That’s saying a lot… or maybe not. All unknowns. The truth is that this is a preliminary presentation because the availability of the model is very limited. In fact, the company has not even published internal benchmarks and that makes it difficult to validate such claims. Some users have shared theoretical results of the behavior of Qwen 3.8 and according to said data it does seem that we are facing a prodigious model, but one that is also unknown details such as cost or efficiency. Meanwhile, Kimi K3 already shows his power. The launch comes just days after Kimi K3 have managed to overcome to Fable 5 and GPT-5.6 Sol in certain specific tests of the Arena.ai benchmark platform. It also surpassed Opus 4.8 in the text generation test classification, something equally striking, especially if we take into account that the Chinese model costs 40% less. The demand for Kimi K3 has been so high that Moonshot AI has had to announce that for now need to cancel new subscriptions to deal with the enormous amount of requests that their servers are receiving. GLM 5.2 had already struck its own blow. We have had a very busy summer in terms of new AI models from the Far East. In June The big surprise was carried out by GLM-5.2the open Zhipu AI model that with its 744 billion parameters managed to be on par with Opus 4.8 at a fraction of its price. This model left behind all its Chinese competitors at the time (MiniMax, DeepSeek V4 Pro, Kimi K2.6), and began to make it clear that China had “a Mythos at home”. The pattern that begins to be drawn. Neither GLM-5.2, nor Kimi K3 later nor now Qwen 3.8 need to be the best models in the world to change the rules of the game: for companies and developers, having access to a model that performs almost like the best, that costs (sometimes much) less and that can even be installed in their own systems because they are open models can be more attractive than paying for the very expensive frontier models from OpenAI or Anthropic. Each launch actually calls into question the exorbitant amounts these companies are investing in ever larger data centers. Alibaba scores the same. The Chinese company will have to confirm with data that Qwen 3.8 really is as good as they say, but for now they have already achieved a relevant victory: the Beijing government approved Apple Intelligence, and will allow iPhones, iPads and Macs to use said technology in the Asian giant with a very special detail: the AI ​​models used will be from Alibabanot from Google. I distill, you distill, he distills. And while all this is happening, Anthropic accuse Moonshot and other Chinese companies to “distill” their models on an industrial scale to develop their own proposals. That is to say: they claim that if the Chinese models are so good it is because they are doing a kind of reverse engineering on models like Claude Opus 4.8, for example. But the fact that many Chinese models are open has also allowed US companies to take advantage of these models for all types of projects, including specific models. like Composer 2.5 from Cursor or the new Inkling from Thinking Machines that It is based on DeepSeek-V3. The gap disappears. The launch of these models demonstrates that the gap between Chinese and American AI models has narrowed significantly. Not long ago it was said that it took China about six months to match the capacity of US models, but these developments make it clear that now it only takes a few weeks before models comparable in performance appear, but with open weights and a reduced cost. If the race was already getting interesting, now it gets fascinating. In Xataka | A company decided to give the keys to its systems to an AI agent. The AI ​​agent deleted its entire database

The hot Jupiters are evaporating, their winds reach 7 km/s and yet something is slowing them down

The hot Jupiters They are fascinating planets. They orbit so close to their star that they sometimes have orbits of less than a day. Solar radiation is very high, so much so that sometimes these planets are practically evaporating. And they are usually tidally locked. That is, they have one face always facing the Sun and the other always facing the opposite side. As a result, one side is much hotter than the other and receives more radiation, so the gases in its atmosphere ionize, transforming into plasma and moving at high speeds. Put very briefly, they have the strongest winds of all the known planets. However, recently a team of scientists led from the Côte d’Azur Observatory in France, has discovered something very strange. Seven hot Jupiters in which the winds flow much slower than expected. The only explanation that seems logical for this phenomenon is that they are surrounded by a magnetic field. And it is great news, since, if confirmed, it would be the first detection of magnetic activity beyond our solar system. Totally counterintuitive. The speed of a planet’s winds can be measured by tracking the vaporized iron present in the gases in its atmosphere. The authors of the study that has just been published did so with 7 hot Jupiters thanks to two instruments: MAROON-X, from the Gemini North telescope, and ESPRESSO, from the Very Large Telescope (VLT). When analyzing the results they saw that these planets had very high speeds, between 2 and 7 kilometers per second. The winds of our own Jupiter, the fastest in the solar system, are 0.4 km/s, to give us an idea. What happens is that these winds went slower the hotter the planet was. One of the authors of the study, Vivien Parmentier, has rated it as something “totally counterintuitive”, since the logical thing is that the higher the temperature, the faster the wind flows. The key must be in the presence of a magnetic field. In fact, with all this temperature and speed data, they have even been able to calculate its intensity. The thing is about temperatures. Generally, the higher the temperature, the greater the difference between the dark and light sides of the planet and the more excited the ions in the plasma are, so the wind generally moves faster. The logical and expected thing would be that the higher the temperature of a hot Jupiter, the faster its wind. The speeds are very high, but much slower than expected. Furthermore, they are slower the hotter the planet is. The best explanation for this event is the presence of a magnetic field. Magnetic activity and wind. When a magnetic field acts on a moving charged particle, it is affected by something known as the Lorentz force. Very briefly, what happens is that the speed changes direction. The particle does not stop, but goes from flowing freely to being confined within the magnetic field. Every time he encounters his lines, they make him change direction. If we see this as a whole for the entire plasma, since it cannot move freely, its speed decreases. This would explain why a magnetic field was slowing down the wind. But why does it brake more the higher the temperature? Auroras on Earth The secret is inside. The magnetic field of a planet is directly related to the movement of the liquid metals inside it. For example, in the case of Earththe movement of molten iron and nickel on the outside of its core generates electrical currents, which give rise to a geomagnetic field that extends into space. They are responsible for us having that magnetic field that protects us from the sun’s inclemencies. The higher the temperature of a planet, the more violently the molten metals inside it move and, therefore, within limits, the more intense the magnetic field will be. In turn, the more intense it is, the more it will slow down the winds. Possible auroras. The location of auroras on Earth is related to the magnetic field. Another of the authors of the study, Bibiana Prinoth, points out that she likes to imagine that one of these Jupiters has a sky “covered by curtains of colorful light that dance over a planet that is half in perpetual day and half in endless night.” What is it for?. Now that we know that some exoplanets have a magnetic field, we could also take it into account when selecting habitable planets. Logically, hot Jupiters are not candidates at all. However, other less inhospitable planets may also have this protective shield. We already know that it is not enough to just be in the habitable zone. Other qualities, such as housing a sufficient amount of water either be far from supermassive black holes These are conditions that can help us refine the search much better. Each new discovery brings us a little closer to that great discovery. Image | Gemini International Observatory/NOIRLab/NSF/AURA/M.
