Microsoft sets new internal limits on AI token usage to control spending

Meta has introduced Muse Code, a new artificial intelligence agent designed for programming and game creation. This model is based on the recently launched Muse Spark 1.2 and has the capability to execute large-scale coding tasks.

With this launch, the company aims to compete with giants in the generative AI sector, such as Anthropic and OpenAI. On X, Mark Zuckerberg shared results from internal tests, comparing the new agent with various Large Language Models (LLMs) on the market, including Claude Opus 5 and GPT-5.6 (in Sol and Terra versions).

Preliminary results indicate that Muse Code's performance is still at an intermediate level when compared to its direct competitors. A notable feature of Muse Code is its ability to handle extensive projects, which it achieves by dividing tasks among multiple agents.

Two games developed with this new AI were presented on Meta's blog, displaying simplified mechanics and graphics. Muse Code is already available in beta version. Muse Spark 1.2 is specifically aimed at coding activities, ranging from bug fixing to data interpretation, while maintaining the qualities of Muse Spark 1.1 for general AI agents.

Although related, no information was provided regarding the model's improvements in cybersecurity or scientific research. The figures presented by Meta suggest that the AI falls slightly short of current Anthropic models, although it manages to surpass GPT-5.6 in certain situations. In analyses conducted by Terminal Bench 2.1, Muse Spark 1.2 ranks second, with performance close to Claude Opus 5, contrary to what Meta's internal benchmark shows.

Among the points highlighted by Zuckerberg's company are the ability to manage prolonged tasks and maintain context understanding throughout the entire process. Additionally, the AI can map and improve its own training, surpassing Muse Spark 1.1 in this aspect. Focused on programming, the new agent promises good performance in game development, which often requires multiple layers of code and various logical conditions.

In the release of Muse Spark 1.2 on its blog, Meta also demonstrated the AI's potential with three examples, two of which were simple games. The first, named Embervault, features an isometric perspective and a board format where the player controls a robot that must eliminate constantly pursuing enemies; the gameplay demands fluidity, but the website showed freezes during the test. The second game, Avo Lawn, is a 2D tower defense type, where zombies advance slowly towards the player. In this game, the user collects seeds and acquires fruits to strengthen their defenses, lasting five attack waves, presenting a slow pace but with potential to be a good mobile game.

Researchers have identified hundreds of millennia-old geoglyphs hidden in the Amazon Forest. Initially, in the 1980s, geographer Alceu Ranzi noticed large geometric grooves while flying over the area between Rio Branco, in Acre, and Porto Velho, in Rondônia, using a window of a commercial airplane.

Intrigued by the finding, Ranzi returned to the region with a team of photographers and other researchers. This initial investigation led to the revelation of the first geoglyphs in the area: immense symbols carved and drawn directly onto the ground, created by ancient societies that lived in the Amazon.

Currently, technological advancements have facilitated the effort to decipher these structures in the interior of the tropical forest. A recent study, conducted by Brazilian researchers and published in the journal Nature, located 396 geoglyphs hidden in the forests of southern Amazonia, which were invisible due to dense vegetation.

The discovery was made possible by the use of LiDAR (Light Detection and Ranging) technology, which works by sending millions of laser beams from drones or aircraft toward the ground. When hitting an object or structure, the laser is reflected back to the device, allowing for the creation of a three-dimensional map of the underlying terrain.

Thanks to LiDAR, geoglyphs on the ground that were not visible in satellite images have been exposed. The investigation covered approximately 4,5 thousand square kilometers in the states of Acre, southern Amazonas, and also parts of Bolivia and Peru.

Most of the findings are associated with other important structures, such as circulation routes and probable ceremonial sites. On average, each geoglyph occupies almost three hectares, with some being nine meters wide and having a depth of nearly five meters. The largest recorded site discovered spans over 48 hectares.

Researchers link the construction of these works to the Aquiry civilization, an indigenous community that inhabited the southwestern Amazon between 6 BC and 9 AD. Evandro Ferreira, a professor at the Federal University of Acre (UFAC), commented in an interview with Super that he considers this people to possess highly developed knowledge.

Ferreira exemplified that 'they knew how to manage the forest' and that the elaboration of the geoglyphs required a large number of people, given that it was a complex task. He added that excavations indicate they cultivated manioc, in addition to having access to beans and peanuts.

With this new discovery, the total number of known geoglyphs in the region reaches 1,700. However, Ferreira suspects that the actual number could be considerably higher. He calculated that by extrapolating the 396 geoglyphs found across the entire area occupied by the Aquiry (about 185 thousand square kilometers), there could be up to 30 thousand geoglyphs.

It is relevant to note a historical aspect: the first geometric forms were only detected in the 1980s due to the deforestation process. At that time, the growth of livestock farming and the construction of highways, such as BR-317, removed extensive areas of the forest, allowing for the observation of the terrain through aerial means.

Although LiDAR has allowed analysis of areas with dense forest, revealing hidden symbols, the technique has limitations. According to Professor Ferreira, 'as you move towards Central Amazonia, the forest is denser and the effectiveness of the laser decreases,' with precision potentially dropping from 10% to 50% in those regions.

Similar geoglyphs have been found in countries such as Peru, including the famous Nazca Lines. Peruvian drawings include representations of animals, human beings, plants, and imaginary figures, in addition to geometric patterns.

The Nazca civilization consisted of advanced farmers, capable of thriving in a difficult geographical environment, located approximately 1,700 kilometers from the Aquiry in the Amazon. The vast quantity of geoglyphs in the southwestern Amazon leads archaeologists to reevaluate theories about the development of pre-colonial civilizations. One of the main changes is the perception of the size of these societies; previously, it was believed that indigenous groups were small, but now many archaeologists estimate that the population peak of the Aquiry could have ranged between 1.25 million and 3 million inhabitants during the period between 100 AD and 300 AD, as it would require, on average, about 300 people to build and maintain each geoglyph.

The manufacturers Hyundai and Kia have begun producing components that conventional production methods cannot fabricate. Both South Korean companies presented details about the operation of the Additive Manufacturing Solutions Center (AMSC), located at the Namyang R&D Center in South Korea. This center represents the first installation of the Hyundai Motor Group dedicated exclusively to 3D printing research and production.

This center was established about thirty years after the group introduced its first industrial 3D printer in 1996. The methodology employed reverses the usual process: instead of relying on molds, dies, or machining, which removes material and restricts the shape of the parts, additive manufacturing gradually adds material, layer by layer, until the exact configuration defined in the digital file is achieved.

In practice, this technology enables the creation of lighter parts with geometries that would be impossible to obtain through casting or stamping. For polymeric materials, the AMSC uses techniques such as vat photopolymerization, covering Digital Light Processing (DLP) and stereolithography (SLA), in addition to powder bed fusion, which minimizes waste and eliminates the need for support structures.

Regarding metals, the center operates advanced systems of powder bed laser melting and directed energy deposition. Among these is DED-WAAM, which uses a welding arc to stack materials such as steel, stainless steel, aluminum, and titanium into large structural components.

Every produced part must pass through the Quality Inspection Cell, where its dimensions are verified and it undergoes rigorous tests for tensile strength, flexural rigidity, and impact resistance. Furthermore, the manufacturers themselves conduct internal metallurgical and material analyses to ensure the final product meets the same standards required for mass production.

The applications of the AMSC have far exceeded the prototyping phase. Currently, it manufactures jigs and fixtures used directly on assembly lines, as well as spare parts for discontinued models whose original tooling would be unfeasible to reactivate. In the restoration sector, engineers managed to recreate a side sill component of the Hyundai Pony using 3D scanning and reverse engineering, achieving an finish identical to the original.

In motorsports, 3D printing is already applied in the manufacturing of brake ducts, shock absorber mounts, and stabilizer bar blades, where the combination of lightness and rigidity is crucial. The group also develops the concept of Design for Additive Manufacturing, designing the part from the beginning to be printed. This allows consolidating several components that previously needed to be assembled separately and incorporating truss structures to reduce weight without compromising strength.

Hanwoo On, senior manager of the Additive Manufacturing Solutions team, commented on the advancement, stating that the company is 'rapidly internalizing additive manufacturing technologies.' He added that the use of these technologies now extends to high-value items outside the vehicle, such as manufacturing tools and equipment consumables.
