Former Meta executive Sarah Wynn-Williams is set to testify before the US Senate Judiciary Committee on Wednesday, revealing how the company’s AI model, Llama, played a critical role in accelerating China’s AI capabilities — particularly contributing to the rise of DeepSeek.

Actively endorsed by Chinese officials, DeepSeek has emerged as a formidable rival to OpenAI, with its launch costing just $6 million — a fraction of what most large language models require. Its emergence has created ripples across the world with many seeing it as an affordable alternative to AI models from OpenAI and Meta.

Citing “Project Aldrin” as Meta’s secret mission to get into China, Wynn-Williams’ written testimony stated, “Meta built a physical pipeline connecting the United States and China. Meta executives ignored warnings that this would provide backdoor access to the Chinese Communist Party, allowing them to intercept the personal data and private messages of American citizens. The only reason China does not currently have access to US user data through this pipeline is because Congress stepped in.”

She also claimed that “Meta’s AI model – Llama – has contributed significantly to Chinese advances in AI technologies like DeepSeek.”

According to the testimony, Meta started briefing the Chinese Communist Party as early as 2015, focusing on critical emerging technologies, including AI, the explicit goal being to help China outcompete US companies.

“There’s a straight line you can draw from these briefings to the recent revelations that China is developing AI models for military use, relying on Meta’s Llama model. Meta’s internal documents describe their sales pitch for why China should allow them in the market by quote ‘help[ing] China increase global influence and promote the China Dream,’” Wynn-Williams’ testimony read.

AI arms race

These revelations surface at a tense moment in US-China relations, as Washington continues to impose export restrictions on advanced AI chips in a bid to curb China’s progress in developing next-generation generative AI models.

“The United States has introduced regulatory guardrails, including export controls and multilateral agreements, to prevent unintended AI knowledge transfer — particularly to strategic competitors like China. Yet enforcement remains a major challenge, as loopholes and evasion tactics limit effectiveness. The core challenge lies in balancing national security with the need to foster domestic innovation,” said Prabhu Ram, VP of Industry Research Group at CyberMedia Research.

The recent disclosures about Facebook allegedly aiding China in AI development could significantly undermine global efforts to safeguard sensitive AI technologies. If proven true, it may trigger fresh calls for stricter compliance, re-evaluation of public-private partnerships, and even new international AI norms.

“For years, regulation has focused on the hardware layer — chips, servers, and physical exports. But foundational models are different. They don’t move through ports or carry serial numbers,” said Sanchit Vir Gogia, chief analyst and CEO at Greyhound Research. “They are shared digitally, openly, and rapidly. Once they’re released, they’re almost impossible to track. At Greyhound Research, we believe the US and its allies must now develop an AI-native regulatory toolkit. The old frameworks simply don’t apply. We’re not advocating for a crackdown on open-source innovation — but we do believe smarter, more precise controls are urgently needed.”

Such a breach of trust could erode collaboration among democratic AI powers and give China a strategic edge in critical AI applications, including military and surveillance.

As this new development can put in more guardrails, restricting the development of global AI models, Ram added, “Overly broad restrictions could stifle US research and weaken its global AI leadership. Targeted, proportionate controls and stronger enforcement are needed.”

However, according to a Rest of World analysis, the US and China have been the most frequent partners in AI research over the past 10 years.   

Open source at a crossroads

Open-source models such as Llama give developers and companies the freedom to train, fine-tune, and run AI on their own infrastructure — enabling full control over performance, privacy, and cost. They also help avoid lock-in to closed vendors, making it easier to build secure, efficient, and future-ready AI systems tailored to specific needs.

While open source has significantly lowered the barriers to entry for AI innovation, experts believe that Meta’s Llama models have been central to this shift enabling a wide range of companies to build AI solutions. This openness also raises complex questions around ownership, accountability, and national security — especially when models are repurposed in jurisdictions with differing regulatory norms and strategic goals.

“Emerging markets are likely to accelerate efforts to establish clearer AI governance frameworks — balancing local innovation with context-specific challenges. At the same time, they will seek to reduce risks of misuse and dependency on external foundations through proactive guardrails that ensure responsible oversight and effective management,” Ram said.

Google’s new on-demand generative AI (genAI) analyst for spreadsheets stood out among a slew of new AI features for its Workplace productivity suite announced at this week’s Cloud Next event in Las Vegas.

The upcoming “help me analyze” feature in the Google Sheets application in Workspace  can take information from tables and provide instant data analysis and insights. It does so without users having to write a single formula, chart or pivot table, said Kristina Behr, vice president of product for Google Workspace. 

[ Related: Google Cloud Next ’25: News and insights ]

“It’s like having a data analyst beside you to help,” Behr said.

The genAI analyst is designed to reduce the manual chore of digging through unstructured data in spreadsheets. It can catch unidentified trends, suggests how to go forward on research, and can create charts, Google said.

The feature will be available later this year, though no specific date was named.

Google also announced Workspace Flows, which Behr described as “a way to automate work across Google Workspace apps.”

Users can, for example, automate a stream of jobs involved in document reviews, customer support requests, or product analysis. One such use case: Workspace Flows can approve branding copy by referring to a collection of marketing data. Or it can handle customer service requests by referring to support documents.

“A lot of the work we do today requires context and reasoning; it’s not a linear stream of straightforward tasks,” Behr said.

The automation needs to be tailored by users via the Gemini custom AI agent builder called Gems. “Simply describe what you need in plain language and Workflows will design and build sophisticated, logic-driven flows — no complex coding or configuration needed,” she said.

While gen AI agents exist in many forms, this tool is aimed at everyday users who want to spend their time more productively. “It’s not just for IT admins or tech experts. It’s for everybody,” Behr said.

The feature will initially be available as part of the Alpha program, which is mainly available to large customers who bought Gemini prior to the January price hikes.

Google also added a feature called “help me refine” to Google Docs; it’s a genAI tool that can help structure or improve a written document. The feature also generates audio overviews that could be in the form of a full audio readout or “podcast style summaries if you need the highlights in a human-sounding digestible way,” Behr said.

Google rival Microsoft already has a similar Copilot feature that can summarize or improve Word documents.

In January, Google hiked the prices of Google Workspace, which included Gemini access to all Google Workspace users. Those price hikes for Workspace are likely to help Microsoft, especially with smaller and mid-sized companies, even though Google includes Gemini AI now with Workspace, Irwin Lazar, principal analyst at Metrigy, said in a recent interview with Computerworld.

The cloud-based productivity suite now has more than 3 billion users and over 11 million paying customers, Behr said. “We’re seeing over 2 billion AI assists monthly to business users within Workspace and meaningful gains across organizations using AI,” she said.

Democratic Senators Elizabeth Warren and Ron Wyden have launched a formal inquiry into partnerships between tech giants Google and Microsoft, and AI startups, demanding detailed information about arrangements they fear may be circumventing antitrust scrutiny while consolidating power in the rapidly evolving AI market.

In identical letters sent to Google and Anthropic, as well as Microsoft and OpenAI, the lawmakers expressed concern that these corporate partnerships “discourage competition, circumvent our antitrust laws, and result in fewer choices and higher prices” for businesses and consumers using AI tools.

All four companies have been given until April 21 to respond to a series of pointed questions about their relationships.

The inquiry comes as enterprise customers increasingly depend on these AI systems, but may face limited options and higher costs if market consolidation continues unchecked.

Google, Anthropic, Microsoft, and OpenAI did not comment on the development.

“De facto mergers” without regulatory oversight

The senators’ letters specifically highlight Google’s 14% ownership stake in Anthropic after investing $3 billion, while seeking information from Microsoft regarding the “terms of its relationship” with OpenAI.

“These arrangements sometimes function as de facto mergers – allowing companies to consolidate talent, information, and resources – all while bypassing the scrutiny typically applied to mergers and acquisitions,” the senators wrote in their letters to both sets of companies.

The lawmakers cited a January 2025 Federal Trade Commission (FTC) report warning that such partnerships risk “locking in the market dominance of large incumbent technology firms.” They also referenced the FTC and Department of Justice’s merger guidelines, which note that even partial acquisitions may present “significant competitive concerns” by affecting firms’ incentives and strategies.

Computing resources as a competitive advantage

A major focus of the inquiry is how these partnerships potentially monopolize limited computing resources critical for AI development. The senators questioned whether Anthropic and OpenAI receive preferential access to Google’s and Microsoft’s computing capacity over other cloud customers, respectively, and asked for details on payment arrangements for these resources.

For enterprise customers, this could translate to an uneven playing field where only select AI providers have access to the necessary infrastructure to develop competitive models.

“Partnerships between CSPs and AI developers, if left unchecked, may accelerate consolidation of the AI sector, ultimately driving up prices and choking off innovation,” the letter stated.

The lawmakers also asked pointed questions about capital expenditures on AI infrastructure and how much has been recouped from profits earned by the AI partners, suggesting concern about cross-subsidization between the technology companies.

Talent consolidation and information sharing

Another key concern is the movement of talent and information between partner organizations. The senators asked both sets of companies whether individuals currently serve on boards or hold positions at both companies simultaneously, and about the flow of employees between the partner companies.

Enterprise buyers may face a market where fewer independent teams are developing competing AI solutions if the industry consolidates around these dominant partnerships.

The letter specifically referenced the FTC’s finding that some partnerships “embed engineers in one another’s companies, allowing for information transfer about technology and intellectual property” that enables “Big Tech to consolidate AI talent.”

High switching costs create lock-in

The senators expressed particular concern about how these partnerships may create technical and financial barriers that lock AI developers into specific cloud service providers (CSPs).

“Exclusivity contracts might restrict an AI developer whose needs evolve to be better suited to another CSP or who might benefit from a multicloud solution,” the letter stated, noting that “hefty egress fees can raise the cost of switching to a new CSP.”

The development of specialized AI semiconductor chips further raises these barriers. The senators noted Anthropic’s use of Google’s proprietary Tensor Processing Units (TPUs) for model training, while similarly questioning Microsoft’s development of the Maia 100 AI chip that incorporates OpenAI’s technology.

For enterprise customers, these interlocking technical dependencies could ultimately mean fewer options and higher costs if competition diminishes.

Acquisition potential raises additional concerns

The senators pointedly asked both Google and Microsoft whether they currently have plans to acquire their AI partners, if acquisition discussions have occurred, and if the AI companies would be amenable to such deals.

This follows the FTC report noting that respondents indicated that “acquisition of the AI developer by its CSP partner was a possibility.”

Complete acquisitions would represent the ultimate consolidation of these partnerships, potentially removing any remaining independence between the companies.

Broader implications for enterprise AI strategy

The congressional inquiry highlights mounting regulatory concern about AI market concentration just as enterprise adoption reaches critical mass. Companies developing AI strategies should consider the potential impact of regulatory action on their chosen AI providers.

If lawmakers determine these partnerships violate antitrust laws, enterprises could face disruption to their AI supply chains. Conversely, stronger antitrust enforcement could potentially create more competitive pricing and innovation in the AI market long-term. The senators’ letters reflect growing concern about AI consolidation, which they note “has received attention from bipartisan groups in Congress, federal antitrust agencies, and enforcers in allied nations like the UK and European Union.”

The Windows Start menu isn’t the best search tool when it comes to professional productivity. Sure, it’s convenient — it’s better than clicking your way through the entire menu to find what you need. But more often than not, it mostly just gets in your way. 

In fact, Microsoft’s Start menu outright disrespects you by ignoring your choice of default web browser and search engine, automatically just shunting you to Bing and Edge for web results instead of doing what you want. I’d rather use a tool that respects my choices — whether that’s Chrome and Google or Firefox and DuckDuckGo.

But there is a better way within the ] Start menu universe, and it’s even made by Microsoft. The company’s new Command Palette tool is a polished replacement for the standard Start menu. It’s a next-gen version of Microsoft’s PowerToys Run tool, a keyboard-focused launcher I’ve spent a lot of time with. Microsoft is calling it “version 2” of that software.

If you ever hit the Windows key or click the Start button and find yourself typing something, you should give it a try. And, as an extra bonus, this new tool might just offer some hints about Windows 12, too.

Why Command Palette beats the Windows Start menu

I could recount all the ways the Start menu fails us — advertisements, embedded web search results that require a registry hack to turn off, and, of course, that stubborn insistence on using Bing and Edge. We’ve all used it, and we all know the problems.

Instead, let’s talk about why Command Palette is an amazing alternative. First and foremost, it’s a power-user tool, and Microsoft’s marketing department doesn’t seem to have its hooks in it yet. Beyond advanced features, that means no ads — and more respect for your choices.

Specifically, Command Palette empowers you to:

• Search using your default browser and search engine: You can’t really use the Start menu to search the web unless you actually like Bing and Edge. With Command Palette, you get an easy keyboard-focused launcher you can access from anywhere in Windows to perform a web search — no Alt+Tabbing to your web browser required. It’s how Windows should work out of the box.
• Launch apps — and switch to windows, too: You can use this tool to find and launch apps just as you would from the Start menu, but you can also switch to open windows from right within it. It’s a keyboard-centric way of digging up any buried window — no matter where it might be hiding.
• Install extensions to add features: It’s early days for Command Palette, so no extensions are publicly available. But you’ll soon be able to grab extensions from the Microsoft Store to add extra features. The older PowerToys Run tool has a wide variety of extensions for everything from searching your browser’s bookmarks to finding notes in OneNote.

Each “command” in the palette has its own customizable search shortcuts for easy access, too.

Command Palette includes a variety of “commands” — and you’ll eventually be able to install more.

How to get started with Command Palette

Command Palette is easy to use. First, install Microsoft PowerToys if you haven’t already — it’s free. And there are many other useful tools within in it.

Then, press Windows+Alt+Space. You’ll see a search box in the middle of your screen.

From there, you can simply type whatever you want and use the arrow keys and Enter to select a result. Command Palette can help you launch applications on your computer, switch to open windows, find files, search the web with your default browser and search engine, perform quick math calculations, and more.

To dig into options and configure things, click the “Settings” button at the bottom of the Command Palette launcher window. For example, you can change the key combination that launches it, if you like. You’ll find options for configuring individual “extensions” — including those that let you assign shortcuts to different types of searches — by clicking “Extensions” at the left side of the window.

Note: if Command Palette doesn’t pop up for you at all, you might need to launch or update PowerToys first. To check, open your Start menu, search for “PowerToys,” and launch it. Then, click the “General” pane and look for the “Update” button. Install any available updates. (Command Palette was added in PowerToys v0.90.0.)

Easy web searches were perhaps the best feature in PowerToys Run, and they return in the new Command Palette interface.

Advanced Command Palette tips

Command Palette can do even more than you see on the surface. Here are some ways to really upgrade your experience:

• Use search shortcuts: Type the right characters before a query to search in a specific way. For example, you can type ?? and then type a web search or type $ and then type a phrase (like “Bluetooth”) to search for specific settings.
• Assign keyboard shortcuts to individual search types: Want an easy way to search the web from anywhere? Try assigning a custom keyboard shortcut to the web search shortcut. You can do this from the Command Palette’s Settings window — press Windows+Alt+Space to open Command Palette, click “Settings,” click “Extensions” at the left side, click an option (like Web Search), click the action under Commands (like “Search the Web”) and enter the hotkey and alias you prefer.
• Make Caps Lock launch Command Palette: You can remap the Caps Lock key to send a Windows+Alt+Space signal when you press it, turning Caps Lock into your convenient Command Palette key. To do this in just a few clicks, open the PowerToys window and find the Keyboard Manager PowerToy — then follow these easy steps.

All of this is just scratching the surface. For more, dig your way through the settings app. Many parts of Command Palette and many of its extensions are customizable, and you’ll find ample options there.

You can assign global hotkeys and convenient aliases to any command you like.

Why Command Palette smells like Windows 12

Now, for the extra twist: Either Microsoft is suddenly getting way more serious about PowerToys, or Command Palette may form the groundwork for a future Windows 12 feature.

• First, this tool just feels too polished. PC power users like myself loved PowerToys Run — we didn’t need a whole new version of the tool with a more polished, streamlined interface.
• Second, Microsoft has put a lot of work into the extension model. It’s built on the kind of model that Windows apps use — not just a collection of enthusiast-style add-on scripts dumped in a folder, like PowerToys Run. You’ll be able to get extensions from the Microsoft Store, while PowerToys Run has a community extension gallery. It feels as though Microsoft is building up infrastructure here. 
• Third, Command Palette’s settings are designed in an unusual way. Rather than having the typical page of settings in the larger PowerToys window, Command Palette has its own settings window you access from the launcher. It’s like it’s being designed to be self-contained, so it can be picked out of the PowerToys package, modified, and bundled with Windows.

Hey, maybe I’m wrong — maybe Command Palette heralds a new and glorious age of Microsoft taking PowerToys much more seriously. Maybe Microsoft is invested in polish as we’re nearing version 1.0 of that software, more than five years after its initial public release. That would also be nice!

Of course, there’s one part of Command Palette that doesn’t feel like it belongs in Windows 12. I’ll be shocked if Microsoft makes a built-in Windows search feature that actually respects your chosen browser and search engine for a change. But, we’ll see. Maybe the company’s marketing department just hasn’t gotten its teeth into this new feature yet.
