From creating art and writing code to drafting emails and designing new drugs, generative AI tools are becoming increasingly indispensable for both business and personal use. As demand increases, they will require even more computing power, memory and, therefore, energy. That’s got scientists looking for ways to reduce their energy consumption.

In a paper published in the journal Nature, Aydogan Ozcan, from the University of California Los Angeles, and his colleagues describe the development of an AI image generator that consumes almost no power.

AI image generators use a process called diffusion to generate images from text. First, they are trained on a large dataset of images and repeatedly add a statistical noise, a kind of digital static, until the image has disappeared.

Then, when you give AI a prompt such as “create an image of a house,” it starts with a screen full of static and then reverses the process, gradually removing the noise until the image appears. If you want to perform large-scale tasks, such as creating hundreds of millions of images, this process is slow and energy intensive.

A light-based approach

The new diffusion-based image generator works by first using a digital encoder (that has been trained on publicly available datasets) to create the static that will ultimately make the picture. This requires a small amount of energy. Then, a liquid crystal screen known as a (SLM) imprints this pattern onto a . The beam is then passed through a second decoding SLM, which turns the pattern in the laser into the .

Unlike conventional AI, which relies on millions of computer calculations, this process uses light to do all the heavy lifting. Consequently, the system uses almost no power. “Our optical generative models can synthesize countless images with almost no , offering a scalable and energy-efficient alternative to digital AI models,” said Shiqi Chen, lead author.

The researchers tested their system on various images used to train AI models, including those of celebrities and butterflies, as well as full-color pictures in the style of Dutch painter Vincent Van Gogh.

The results were comparable to those of conventional image generators, but were created with much less energy. This breakthrough has the potential to reduce the carbon footprint of AI-generated content significantly.

The technology could also find its way into a variety of applications. Because the system is so fast and requires minimal energy, it could be used for things like creating images and videos for virtual and augmented reality displays, or for small devices like a smartphone or wearable electronics, such as AI glasses.

VTL Group boosts output by 10% with Coats Digital’s GSDCost solution

VTL Group boosts output by 10% with Coats Digital’s GSDCost solution



Coats Digital is delighted to announce that VTL Group, one of the largest vertically integrated textile manufacturers in the Mediterranean region, has adopted Coats Digital’s GSDCost solution to standardise production methods, increase productivity, and improve pricing accuracy across its Tunisian operations. The initiative is already showing a significant impact, with VTL reducing standard minute values (SMVs) by 15–20% and increasing line output by 10% across its three, key sewing facilities.

With over 5,000 employees and 3,000 sewing machines across 90 sewing lines, VTL Group specialises in jersey knits and denim, producing up to 20 million garments per year for world-renowned brands such as Lacoste, Adidas, G-Star, Hugo Boss, Replay and Paul & Shark. The company operates six garment production units, along with dedicated facilities for screen printing, knitting, dyeing and textile finishing. This extensive vertical integration gives VTL complete control over quality, lead-times and cost-efficiency, which is vital for meeting the stringent demands of its global customer base.

VTL Group has adopted Coats Digital’s GSDCost to standardise production, boost productivity, and improve pricing accuracy across its Tunisian operations.
The solution cut SMVs by 15–20 per cent, raised line output by 10 per cent, and enhanced planning, cost accuracy, and customer confidence, enabling competitive pricing, lean operations, and stronger relationships with global fashion brands.

Prior to implementing GSDCost, VTL calculated capacity and product pricing using data from internal time catalogues stored in Excel. This approach led to inconsistent and inaccurate cost estimations, causing both lost contracts due to inflated production times and reduced margins from underestimations. In some cases, delays caused by misaligned time predictions resulted in increased transportation costs and operational inefficiencies that impacted customer satisfaction.

Hichem Kordoghli, Plant Manager, VTL Group, said: “Before GSDCost, we struggled with inconsistent operating times that directly impacted our competitiveness. We lost orders when our timings were too high and missed profits when they were too low. GSDCost has transformed the way we approach planning, enabling us to quote confidently with accurate, reliable data. We’ve already seen up to 20% reductions in SMVs, a 10% rise in output, and improved customer confidence. It’s a game-changer for our sales and production teams.”

Since adopting GSDCost across 50 sewing lines, VTL Group has been able to establish a reliable baseline for production planning and line efficiency monitoring. This has led to a more streamlined approach to managing load plans and forecasting. Importantly, GSDCost has given the business the flexibility to align pricing more effectively with actual production realities, contributing to greater customer satisfaction and improved profit margins.

Although it’s too early to determine the exact financial impact, VTL Group has already realised improvements in pricing flexibility and competitiveness thanks to shorter product times and better planning. These gains are seen as instrumental in enabling the company to pursue more strategic orders, reduce wasted effort and overtime, and maintain the high expectations of leading global fashion brands.

Hichem Kordoghli, Plant Manager, VTL Group, added: “GSDCost has empowered our teams with reliable data that has translated directly into real operational benefits. We are seeing more consistent line performance, enhanced planning precision, and greater confidence across departments. These improvements are helping us build stronger relationships with our brand partners, while setting the foundation for sustainable productivity gains in the future.”

The company now plans to expand usage across an additional 30 lines in 2025, supported by a second phase of GSD Practitioner Bootcamp training to strengthen in-house expertise and embed best practices throughout the production environment. A further 10 lines are expected to follow in 2026 as part of VTL’s phased rollout strategy.

Liz Bamford, Customer Success Manager, Coats Digital, commented: “We are proud to support VTL Group in their digital transformation journey. The impressive improvements in planning accuracy, quoting precision, and cross-functional alignment are a testament to their commitment to innovation and excellence. GSDCost is helping VTL set a new benchmark for operational transparency and performance in the region, empowering their teams with the tools needed for long-term success.”

GSDCost, Coats Digital’s method analysis and pre-determined times solution, is widely acknowledged as the de-facto international standard across the sewn products industry. It supports a more collaborative, transparent, and sustainable supply chain in which brands and manufacturers establish and optimise ‘International Standard Time Benchmarks’ using standard motion codes and predetermined times. This shared framework supports accurate cost prediction, fact-based negotiation, and a more efficient garment manufacturing process, while concurrently delivering on CSR commitments.

Key Benefits and ROI for VTL Group

  • 15–20% reduction in SMVs across 50 production lines
  • 10% productivity increase across key sewing facilities
  • More competitive pricing for strategic sales opportunities
  • Improved cost accuracy and quotation flexibility
  • Standardised time benchmarks for future factory expansion
  • Enhanced planning accuracy and load plan management
  • Greater alignment with lean and sustainable manufacturing goals

NSA urges continuous checks to achieve zero trust | Computer Weekly

NSA urges continuous checks to achieve zero trust | Computer Weekly


The US National Security Agency (NSA) has published its latest guidance on zero trust to secure US federal government IT networks and systems. This is the first of two guidance documents coming out of the NSA, providing “practical and actionable” recommendations that can be applied as best practice to secure corporate IT environments both in the public and private sectors.

In the Zero trust primer document, the NSA defines a “zero-trust mindset”, which means assuming IT environment traffic, users, devices and infrastructure may be compromised. To achieve this, the guidance urges IT security teams to establish a rigorous authentication and authorisation process for all access requests.

In the context of securing the integrity of government IT systems, it said that such a strategy enhances the security posture of networks by rigorously validating every access request, which prevents unauthorised changes, reduces risk of malicious code insertion, and ensures the integrity of software and supply chains

The main takeaway from the NSA regarding zero trust is to never trust users or devices that request network connectivity or access to internal resources. The NSA guidance calls for verification without exception, where dynamic authentication and explicit approval is used across all activities on the network, adhering to the principle of least privilege.

Specifically, the NSA’s latest guidance suggests that IT security teams should assume they are working in an IT environment where there is a breach, which means operating and defending resources under the assumption that an adversary already has a presence in the environment.

The NSA said IT security teams should plan for deny-by-default and heavily scrutinise all users, devices, data flows and requests. This means that IT security teams need to log, inspect and monitor all configuration changes, resource accesses and environment traffic for suspicious activity continuously.

The guidance also recommends explicit verification. This implies that access to all resources is consistently verified, using both dynamic and static mechanisms, which is used to derive what the NSA calls “confidence levels for contextual access decisions”.

Commenting on the guidelines, zero-trust expert Brian Soby, CTO and co-founder of AppOmni, said: “Across the guidance, the emphasis is on continuous logging, inspection and monitoring of resource access and configuration change, plus comprehensive visibility across layers.

“Read plainly, the NSA is suggesting that many programs are built around coarse checkpoints and limited signals, while the real risk lives inside enterprise applications, especially SaaS, where sensitive data and business workflows reside.”

Soby’s understanding of the new guidelines is that effective zero trust requires a thorough understanding of what users can and cannot do, instead of simply relying on their ability to authenticate through network directory services and the authorisation that successful authentication gives them.

“Many security programs still substitute directory groups and simplistic roles for true entitlement materiality, even though effective access in modern SaaS is shaped by application-native permissions, sharing rules, delegated administration, conditional controls and third-party OAuth grants.”

He noted that the NSA’s emphasis on monitoring resource access and configuration change implies that relying on coarse identity abstractions leaves IT security teams blind to the actions and permission shifts that create exposure and enable misuse.

“This gap also lines up uncomfortably well with the breaches and campaigns we are seeing now,” he added.

As an example, Soby said that recent intrusions tied to groups tracked as UNC6040 and UNC6395 have highlighted how attackers can bypass traditional, frontdoor-centred controls by abusing SaaS identities and integrations, including compromised OAuth tokens and third-party application access, to reach and extract data from SaaS environments.

“In that light, the NSA’s guidance supports a sharper conclusion: identity security programs that cannot truly understand user activities, behaviours and the materiality of entitlements inside applications do not match the principles of zero trust,” said Soby. “These often become more performative than effective, leaving security operations centre teams stuck with generic signals like logins when the meaningful attacker activity is happening inside the app.”
