I tested out a buzzy new text-to-video AI model from China

You may not be familiar with Kuaishou, but this Chinese company just hit a major milestone: It’s released the first ever text-to-video generative AI model that’s freely available for the public to test.

The short-video platform, which has over 600 million active users, announced the new tool, called Kling, on June 6. Like OpenAI’s Sora model, Kling is able to generate videos up to two minutes long from prompts.

But unlike Sora, which still remains inaccessible to the public four months after OpenAI debuted it, Kling has already started letting people try the model themselves. Zeyi Yang, our China reporter, has been putting it through its paces. Here’s what he made of it.

Meta has created a way to watermark AI-generated speech

The news: Meta has created a system that can embed hidden signals, known as watermarks, in AI-generated audio clips, which could help in detecting AI-generated content online.

Why it matters: The tool, called AudioSeal, is the first that can pinpoint which bits of audio in, for example, a full hour-long podcast might have been generated by AI. It could help to tackle the growing problem of misinformation and scams using voice cloning tools. Read the full story.

The return of pneumatic tubes

Pneumatic tubes were once touted as something that would revolutionize the world. In science fiction, they were envisioned as a fundamental part of the future—even in dystopias like George Orwell’s 1984, where they help to deliver orders for the main character, Winston Smith, in his job rewriting history to fit the ruling party’s changing narrative. 

In real life, the tubes were expected to transform several industries in the late 19th century through the mid-20th. The technology involves moving a cylindrical carrier or capsule through a series of tubes with the aid of a blower that pushes or pulls it into motion, and for a while, the United States took up the systems with gusto.

But by the mid to late 20th century, use of the technology had largely fallen by the wayside, and pneumatic tube technology became virtually obsolete. Except in hospitals. Read the full story.

Unlocking secure, private AI with confidential computing

All of a sudden, it seems that AI is everywhere, from executive assistant chatbots to AI code assistants.

But despite the proliferation of AI in the zeitgeist, many organizations are proceeding with caution. This is due to the perception of the security quagmires AI presents. For the emerging technology to reach its full potential, data must be secured through every stage of the AI lifecycle including model training, fine-tuning, and inferencing.

This is where confidential computing comes into play. Vikas Bhatia, head of product for Azure Confidential Computing at Microsoft, explains the significance of this architectural innovation: “AI is being used to provide solutions for a lot of highly sensitive data, whether that’s personal data, company data, or multiparty data,” he says. “Confidential computing is an emerging technology that protects that data when it is in memory and in use. We see a future where model creators who need to protect their IP will leverage confidential computing to safeguard their models and to protect their customer data.”

Understanding confidential computing

“The tech industry has done a great job in ensuring that data stays protected at rest and in transit using encryption,” Bhatia says. “Bad actors can steal a laptop and remove its hard drive but won’t be able to get anything out of it if the data is encrypted by security features like BitLocker. Similarly, nobody can run away with data in the cloud. And data in transit is secure thanks to HTTPS and TLS, which have long been industry standards.”

But data in use, when data is in memory and being operated upon, has typically been harder to secure. Confidential computing addresses this critical gap—what Bhatia calls the “missing third leg of the three-legged data protection stool”—via a hardware-based root of trust.

Essentially, confidential computing ensures the only thing customers need to trust is the data running inside of a trusted execution environment (TEE) and the underlying hardware. “The concept of a TEE is basically an enclave, or I like to use the word ‘box.’ Everything inside that box is trusted, anything outside it is not,” explains Bhatia.

Until recently, confidential computing only worked on central processing units (CPUs). However, NVIDIA has recently brought confidential computing capabilities to the H100 Tensor Core GPU and Microsoft has made this technology available in Azure. This has the potential to protect the entire confidential AI lifecycle—including model weights, training data, and inference workloads.

“Historically, devices such as GPUs were controlled by the host operating system, which, in turn, was controlled by the cloud service provider,” notes Krishnaprasad Hande, Technical Program Manager at Microsoft. “So, in order to meet confidential computing requirements, we needed technological improvements to reduce trust in the host operating system, i.e., its ability to observe or tamper with application workloads when the GPU is assigned to a confidential virtual machine, while retaining sufficient control to monitor and manage the device. NVIDIA and Microsoft have worked together to achieve this.”

Attestation mechanisms are another key component of confidential computing. Attestation allows users to verify the integrity and authenticity of the TEE, and the user code within it, ensuring the environment hasn’t been tampered with. “Customers can validate that trust by running an attestation report themselves against the CPU and the GPU to validate the state of their environment,” says Bhatia.

Additionally, secure key management systems play a critical role in confidential computing ecosystems. “We’ve extended our Azure Key Vault with Managed HSM service which runs inside a TEE,” says Bhatia. “The keys get securely released inside that TEE such that the data can be decrypted.”

Confidential computing use cases and benefits

GPU-accelerated confidential computing has far-reaching implications for AI in enterprise contexts. It also addresses privacy issues that apply to any analysis of sensitive data in the public cloud. This is of particular concern to organizations trying to gain insights from multiparty data while maintaining utmost privacy.

Another of the key advantages of Microsoft’s confidential computing offering is that it requires no code changes on the part of the customer, facilitating seamless adoption. “The confidential computing environment we’re building does not require customers to change a single line of code,” notes Bhatia. “They can redeploy from a non-confidential environment to a confidential environment. It’s as simple as choosing a particular VM size that supports confidential computing capabilities.”

Some industries and use cases that stand to benefit from confidential computing advancements include:

Governments and sovereign entities

The Download: robot-packed meals, and the looming fertility crisis

This is today’s edition of The Download our weekday newsletter that provides a daily dose of what’s going on in the world of technology.

Robot-packed meals are coming to the frozen-food aisle

What’s happening: Advances in artificial intelligence are coming to your freezer, in the form of robot-assembled prepared meals. Chef Robotics, a San Francisco-based startup, has launched a system of AI-powered robotic arms that can be quickly programmed with a recipe to dole out accurate portions of everything from tikka masala to pesto tortellini.

Why it matters: You might think the meals that end up in the grocery store’s frozen aisle or on airplanes are robot-packed already, but that’s rarely the case. The vast majority of meals from recognizable brands are still typically hand-packed, because workers are often much more flexible than robots and can handle production lines that frequently rotate recipes. However, advancements from AI have changed the calculus, making robots more useful on production lines. Read the full story.

IVF alone can’t save us from a looming fertility crisis

There are over 8 billion of us on the planet, and there’ll probably be 8.5 billion of us by 2030. We’re continually warned about the perils of overpopulation and the impact we humans are having on our planet. So it seems a bit counterintuitive to worry that, actually, we’re not reproducing enough.

But plenty of scientists are incredibly worried about just that. Improvements in health care and sanitation are helping us all lead longer lives. But we’re not having enough children to support us as we age. Fertility rates are falling in almost every country.

But wait! We have technologies to solve this problem! IVF is helping to bring more children into the world than ever, and it can help compensate for the fertility problems faced by older parents! Unfortunately, things aren’t quite so simple. Read the full story.

The Download: automating warehouse tasks, and problems with recycling plastics

This is today’s edition of The Download our weekday newsletter that provides a daily dose of what’s going on in the world of technology.

AI is poised to automate today’s most mundane manual warehouse task

Before almost any item reaches your door, it traverses the global supply chain on a pallet. More than 2 billion pallets are in circulation in the United States alone, and $400 billion worth of goods are exported on them annually.

However, loading boxes onto these pallets is a task stuck in the past: Heavy loads and repetitive movements leave workers at high risk of injury, and in the rare instances when robots are used, they take months to program using handheld computers that have changed little since the 1980s.

Jacobi Robotics, a startup spun out of the labs of the University of California, Berkeley, says it can vastly speed up that process with AI. If successful, Jacobi aims to replace the legacy methods customers are currently using to train their bots, whittling down the time it takes to code a paletting process from months to a single day.

Here’s the problem with new plastic recycling methods

Look on the bottom of a plastic water bottle or takeout container, and you might find a logo there made up of three arrows forming a closed loop shaped like a triangle. Sometimes called the chasing arrows, this stamp is used on packaging to suggest it’s recyclable.

Those little arrows imply a nice story, painting a picture of a world where the material will be recycled into a new product, forming an endless loop of reuse. But the reality of plastics recycling today doesn’t match up to that idea. Only about 10% of the plastic ever made has been recycled; the vast majority winds up in landfills or in the environment.

Researchers have been working to address the problem by coming up with new recycling methods, sometimes called advanced, or chemical, recycling. But this new approach shares a few challenges with other recycling methods. Read the full story.
