The economics of artificial intelligence are shifting as the cost of open-weight models falls, encouraging wider adoption among enterprises. While foundational model inference costs have dropped significantly—with LLM inference prices falling nearly 90% in some cases—companies are increasing overall spending. Rather than relying entirely on a single costly frontier model, firms are using diverse models for different tasks, leading to higher token consumption and more complex agentic workflows. However, this shift raises concerns about measuring true business value versus raw token consumption and increases the computational intensity of AI deployments.
The cost of open-weight models has decreased drastically, making AI adoption more accessible.
Despite falling token prices, enterprises are spending more on AI due to increased usage and complex multi-model workflows.
Open-weight models now account for a significant share of token use, challenging proprietary dominance.
Exam Points
LLM inference prices fell by over 90% between November 2022 and October 2024.
Open-weight models account for about 35% of token use on certain platforms.
Central Warehousing Corporation (CWC) Managing Director Santosh Sinha raised concerns regarding malpractices in phytosanitary certification at ports, which has led to export rejections of agricultural products like Indian rice and mangoes. Highlighting the challenges faced by Indian exporters under new free trade agreements, the CWC aims to expand its role into integrated logistics, storage, preservation, and treatment to ensure agricultural produce meets international destination market norms. Additionally, the CWC is planning its first hyperloop freight trial at its CFS Logistics Park in JNPT, Mumbai, in collaboration with TuTr Hyperloop.
A recent study published in Science Translational Medicine reveals that Pneumocystis jirovecii, a fungus causing severe pneumonia in immunocompromised individuals, is developing resistance to mycophenolic acid (MPA). MPA is an immunosuppressant drug used in solid-organ transplant recipients to prevent organ rejection. Researchers analysed global samples and found common mutations in the fungal gene producing IMPDH, the enzyme targeted by the drug, suggesting that exposure to the medication exerts selective pressure on the pathogen. This challenges current understandings of antimicrobial and antifungal resistance and highlights the risks of unintended evolutionary pressures from human-targeted therapies.
Pneumocystis jirovecii fungus has been found to evolve resistance to the immunosuppressant drug mycophenolic acid (MPA).
MPA, used in transplant recipients to prevent organ rejection, targets the fungal enzyme IMPDH.
Mutations in the fungal gene producing IMPDH were identified across multiple global samples.
Exam Points
The study analysed 163 P. jirovecii samples from China, Denmark, Germany, Japan, Switzerland, and the U.S.
About 86% of samples from transplant recipients contained a mutation in the IMPDH gene, compared to 13% in non-transplant samples.
Recent research shows that combinations of FETUA proteins from western diamondback rattlesnakes can neutralise rattlesnake venom lethality in mice with significantly higher potency than commercial antivenoms. Because rattlesnakes are immune to their own venom and possess toxin sponges in their bloodstreams, scientists explored these proteins as a broad-spectrum antidote. The study demonstrated that FETUA protein combinations could neutralize multiple dangerous pit viper venoms. If successfully translated into clinical practice, this discovery could lead to next-generation antivenoms that offer cross-species protection against multiple snake species without relying on traditional animal-derived immunisation.
FETUA proteins from western diamondback rattlesnakes have shown high potency in neutralizing various snake venoms.
Rattlesnakes use specific blood proteins and toxin sponges to remain immune to their own venom.
The proposed antivenom approach could offer broad-spectrum protection against multiple pit viper species.
Exam Points
Rattlesnakes have evolved these defensive proteins for 50 million years.
The study tested combinations against C. atrox venom, the Malayan pit viper, and the Chinese moccasin.
The Lindsey O. Graham Sanctioning Russia and Iran Act, 2026, signed by U.S. President Donald Trump, imposes secondary sanctions and tariffs of up to 100% on countries importing Russian and Iranian oil and gas. This poses severe economic challenges for India, a major importer of discounted Russian crude. Under the Act, countries failing to reduce energy imports within stipulated timeframes face punitive U.S. tariffs and trade restrictions. The legislation threatens to strain India-U.S. trade relations, inflate domestic fuel prices, and create inflationary pressures unless exemptions or waivers are secured through diplomatic channels.
The U.S. Act imposes tariffs of up to 100% on nations importing oil and gas from Russia and Iran.
India's reliance on discounted Russian crude makes it highly vulnerable to these secondary sanctions.
The legislation mandates strict timelines for countries to reduce energy imports or face severe trade penalties.
Exam Points
Russia accounted for over 51% of Indian crude oil imports following the Ukraine conflict.
The Act allows the U.S. President to issue a waiver if Russia signs a peace agreement with Ukraine.
The U.S. deployment of space control weapons in earth orbit, as disclosed by U.S. Air Force secretary Troy Meink, has drawn sharp criticism from Russia and China. These capabilities include kinetic and non-kinetic methods designed to disrupt or degrade adversary satellite communications and sensors. The Outer Space Treaty of 1967 prohibits weapons of mass destruction in orbit but does not explicitly ban conventional weapons, creating a legal gray area. While no specific operational details or rules of engagement have been published, the escalation highlights growing militarization in space and the urgent need for international governance.
The U.S. has deployed space control weapons in orbit to counter adversary space activities.
Kinetic and non-kinetic capabilities include physical impacts and electronic interference with satellites.

Exam Points
The Outer Space Treaty entered into force in 1967 during the Cold War.
Article IX of the Outer Space Treaty requires states to have 'due regard' for the interests of other parties.
The United States, Denmark, and Greenland have reached an agreement allowing the U.S. to develop a significant military presence on Greenland while prohibiting other adversaries from establishing military bases. Announced following months of diplomatic tension regarding U.S. territorial ambitions, the security deal aims to strengthen Arctic defense within NATO. While Danish and Greenlandic leaders expressed hope that the pact would ensure regional stability and respect territorial sovereignty, local skepticism remains regarding autonomy and foreign control over strategic Arctic routes.

According to CNN reports, the U.S. military nearly boarded a Chinese vessel in West Asia after an AI-powered chatbot misidentified standard cargo as nuclear weapons-related components. The incident occurred when an analyst used an LLM chatbot that mistakenly flagged the ship's cargo, prompting military preparation for an intercept before officials aborted the mission. The near-miss has sparked widespread concerns among AI researchers, prompting an ethics-related resignation at Anthropic and raising critical questions regarding the reliability of artificial intelligence in military intelligence operations.

U.S. President Donald Trump has extended an executive order imposing a $100,000 fee on H-1B non-immigrant visas for another year, alongside tightened scrutiny through enhanced inter-agency cooperation. The H-1B program, heavily utilized by Indian professionals and global tech firms to employ skilled workers in the United States, faces mounting pressure from immigration crackdowns. While the administration seeks to permanently raise fees to restrict foreign labor, Indian nationals remain the largest beneficiary group, navigating increasingly stringent regulatory hurdles and visa renewals.
