Microsoft-backed OpenAI starts release of powerful AI known as GPT-4

The startup OpenAI on Tuesday said it is beginning to release a powerful artificial intelligence model known as GPT-4, setting the stage for human-like technology to proliferate and more competition between its backer Microsoft Corp and Alphabet Inc's Google. OpenAI, which created the chatbot sensation ChatGPT, said in a blog post that its latest technology is "multimodal," meaning images as well as text prompts can spur it to generate content. The text-input feature will be available to ChatGPT Plus subscribers and to software developers, with a waitlist, while the image-input ability remains a preview of its research. The highly-anticipated launch…

US weapons captured by Russian military in Ukraine head to Iran for ‘reverse-engineering - Report

Russia has been supplying western-manufactured weapons and equipment captured on the battlefield in Ukraine to Iran, hoping that Tehran might reverse-engineer the technology, a CNN report claimed. The report, citing four sources, claimed that US, NATO, and other Western officials had recorded Russian forces taking control of US-made shoulder-fired weapons, including Javelin anti-tank missiles and Stinger anti-aircraft systems that the Ukrainian army left behind on the battlefield. The sources suggest that Russia has shipped some of these weapons to Iran, probably so the country can disassemble them and examine the technology to produce similar weapons. Ukraine has acquired weaponry worth…

Mind-reading AI turns your thoughts into pictures

Artificial intelligence can create images based on text prompts, but scientists unveiled a gallery of pictures the technology produces by reading brain activity. The new AI-powered algorithm reconstructed around 1,000 images, including a teddy bear and an airplane, from these brain scans with 80 percent accuracy. Researchers from Osaka University used the popular Stable Diffusion model, included in OpenAI's DALL-E 2, which can create any imagery based on text inputs. The team showed participants individual sets of images and collected fMRI (functional magnetic resonance imaging) scans, which the AI then decoded. We show that our method can reconstruct high-resolution images…

OpenAI cofounder responds to Elon Musk's criticism that ChatGPT is too 'woke': 'We made a mistake'

In response to Elon Musk's criticism of ChatGPT being too "woke," OpenAI cofounder and president Greg Brockman admitted the startup "made a mistake," in an interview with The Information. Musk, an OpenAI cofounder who has since severed ties with the company, has routinely criticized OpenAI for implementing safeguards that prevent the chatbot from producing responses that could be deemed offensive. "We made a mistake: The system we implemented did not reflect the values we intended to be in there," Brockman, who serves as OpenAI's president, told The Information. "And I think we were not fast enough to address that. And…

Russia’s ‘most feared’ S-400 missile ready for China battle

Russia recently delivered another batch of ‘super lethal’ S-400 ‘Triumf’ long-range air defense system to India, according to reports by multiple media outlets. The Russian Ambassador to India, Denis Alipov, had said last month that Russia would soon deliver the third regiment of the S-400 Triumf surface-to-air missile systems to India. “It (third S-400 regiment) will be completed in the very near future…Both sides are committed to completing the contract, and we certainly will do that. Nothing prevents that,” Alipov said. An unnamed senior Indian defense official reportedly told Janes on March 2 that Russia has completed the delivery of…

China leads US in 37 out of 44 critical and emerging technologies - Report

China has a "stunning lead" in 37 out of 44 critical and emerging technologies as Western democracies lose a global competition for research output, a security think tank said on Thursday after tracking defence, space, energy and biotechnology. The Australian Strategic Policy Institute (ASPI) said its study showed that, in some fields, all of the world's top 10 research institutions are based in China. The study, funded by the United States State Department, found the United States was often second-ranked, although it led global research in high-performance computing, quantum computing, small satellites and vaccines. "Western democracies are losing the global…

Russia displays its own ‘HIMARS’ Tornado-S at IDEX 2023; expert calls it ‘far more potent’ than US’ MLRS

Russia has unveiled its Tornado-S multi-target rocket system at the IDEX 2023 international arms show in Abu Dhabi to sell the weapon to Gulf nations. The Tornado-S multi-target rocket system, similar to the US-made HIMARS, can strike opponent positions at longer ranges and inside enemy territories. In a statement on February 20, Rostec State Corporation, which is marketing this weapon system to Gulf nations, explained the capabilities of the Tornado-S multi-target rocket system. The Tornado-S control system unit enables each munition to have a unique flight assignment, allowing the combat vehicle to salvo attack several targets. Based on a strap-down…

China announces plans to take on Elon Musk’s ‘Starlink’

Chinese researchers are preparing to launch close to 13,000 satellites into a low-earth orbit, in a move which would dwarf – and potentially monitor – Elon Musk’s SpaceX ‘Starlink’ network, which first launched in 2019 and provides satellite internet access to 50 countries. The project, which is codenamed ‘GW’ and is being led by associate professor Xu Can of the People’s Liberation Army’s (PLA) Space Engineering University in Beijing, will see 12,992 satellites operated by the China Satellite Network Group Co launched into orbit, and is designed to improve communications efficiency. The launch schedule remains unknown but the team led…

Under cover of Su-35, Su-30SM fighters, Russia deploys ‘highly modified’ Su-25 attack aircraft to strike Ukraine

On February 16, the Russian Ministry of Defense (RuMoD) highlighted the capabilities of the Su-25 attack aircraft upgraded by the country in a Telegram post titled ‘Upgraded Su-25SM3: Superpower Over The Battlefield’. The post was accompanied by the hashtag ‘Z,’ a letter that became the symbol of the Russian invasion in the initial weeks of the conflict, triggering speculations that the upgraded ground attack aircraft could have been deployed to Ukraine. The development is significant as it comes amid fears of an imminent aerial raid by the Russian Aerospace Forces (VKS) after several fighters and helicopters were stationed close to…

Google’s Bard vs ChatGPT: Here’s what we know so far

Alphabet Inc and rival Microsoft are once again locked in a race to rule the internet zeitgeist after the Google owner launched "Bard" in answer to AI chatbot sensation ChatGPT. Just minutes after Google announced the launch of Bard on Monday, Microsoft said it would hold an event at its Redmond headquarters to reveal its own AI, potentially setting the stage for the next Chrome-versus-Internet Explorer or Gmail-versus-Hotmail. Microsoft-backed OpenAI's ChatGPT has taken the tech world by storm since it was opened for public use last year, as people worldwide got creative with prompts that the conversational chatbot uses to…

ChatGPT isn’t a great leap forward, it’s an expensive deal with the devil

Sometimes, those who would forget history are condemned to repeat it. For those of us with long memories, the current fuss – nay hysteria – surrounding ChatGPT(and “generative AI” generally) rings a bell. We have been here before: in January 1996, to be precise. That was the moment when Joseph Weizenbaum, a computer scientist at MIT, unveiled Eliza, which would have been called the world’s first chatbot if that term had existed at the time. Weizenbaum wrote the software (in a programming language intriguingly called MAD-SLIP) to demonstrate that communications between humans and computers were inevitably superficial. It did that…

Russia and Ukraine battle daily in the sky. So where are the pilots?

Russia and Ukraine are waging a fierce fight in the sky. Russia unleashes drones and missiles. Ukraine often shoots them down with its own missiles, and carries out its own drone strikes. Yet one thing makes this battle distinctive from all previous air wars of the past century: pilots are rare. And this goes very much against the traditional perception of air combat. "Top Gun: Maverick is Oscar-nominated this year for Best Picture. And here we are, watching an air war happening. And it looks very different from anything that we see in Top Gun," said Kelly Grieco, with the…

Scientists can now use WiFi to see through people's walls

It isn’t immediately clear how using only a WiFi signal to track human movement through walls improves personal privacy... but that’s what a new study from Carnegie Mellon University claims. In a recently published paper, the researchers expanded on the study of employing WiFi signals to map human movement, especially in low-light situations that make using other technologies less than desirable. They write: “We developed a deep neural network that maps the phase and amplitude of WiFi signals to UV coordinates within 24 human regions. The results of the study reveal that our model can estimate the dense pose of…
