CANDI: Hybrid Discrete-Continuous Diffusion Models
Pynadath, Patrick, Shi, Jiaxin, Zhang, Ruqi
While continuous diffusion has shown remarkable success in continuous domains such as image generation, its direct application to discrete data has underperformed compared to purely discrete formulations. This gap is counterintuitive, given that continuous diffusion learns score functions that enable joint evolution across multiple positions. To understand this gap, we introduce token identifiability as an analytical framework for understanding how Gaussian noise corrupts discrete data through two mechanisms: discrete identity corruption and continuous rank degradation. We reveal that these mechanisms scale differently with vocabulary size, creating a temporal dissonance: at noise levels where discrete corruption preserves enough structure for conditional learning, continuous denoising is trivial; at noise levels where continuous denoising is meaningful, discrete corruption destroys nearly all conditional structure. To solve this, we propose CANDI (Continuous ANd DIscrete diffusion), a hybrid framework that decouples discrete and continuous corruption, enabling simultaneous learning of both conditional structure and continuous geometry. We empirically validate the temporal dissonance phenomenon and demonstrate that CANDI successfully avoids it. This unlocks the benefits of continuous diffusion for discrete spaces: on controlled generation, CANDI enables classifier-based guidance with off-the-shelf classifiers through simple gradient addition; on text generation, CANDI outperforms masked diffusion at low NFE, demonstrating the value of learning continuous gradients for discrete spaces.

Microsoft reports strong earnings as Azure hit by major outage
Microsoft's CEO, Satya Nadella, speaks at the company's annual developer conference in Seattle, Washington. Microsoft's CEO, Satya Nadella, speaks at the company's annual developer conference in Seattle, Washington. Tech giant reports earnings of $3.72 per share day after deal with OpenAI pushed value of company to more than $4tn Microsoft blew off concerns of overspending on AI on Wednesday, reporting elevated earnings even as it faced an outage of its cloud computing service, Azure, and its office software suite, 365. The strong earnings report comes a day after a deal with OpenAI pushed the value of the tech giant to more than $4tn. After its Xbox and investor relations pages went down, the company issued a statement that said: "We are working to address an issue affecting Azure Front Door that is impacting the availability of some services."
Nvidia becomes first 5 trillion firm as AI rally picks up steam
Nvidia CEO Jensen Huang speaks during an event in Washington on Tuesday. Nvidia achieved a historic $5 trillion market capitalization on Wednesday as CEO Jensen Huang's spree of deals catapults the artificial intelligence frenzy to new heights. The shares closed 3.1% higher at $207.16, propelling Nvidia just over the milestone. It's only been four months since the company cracked the $4 trillion barrier, and the rally has accelerated as Huang forges new agreements to supply companies from Nokia Oyj to Samsung Electronics and Hyundai Motor Group with chips. Nvidia has become the most-important stock in a bull market that's been driven by optimism for AI to revolutionize the global economy.
Trump-Xi meeting: What's at stake and who has the upper hand?
Is the US eyeing its next Latin American target? Why is Trump tearing down parts of the White House? Trump-Xi meeting: What's at stake and who has the upper hand? United States President Donald Trump expects "a lot of problems" will be solved between Washington and Beijing when he meets China's President Xi Jinping in South Korea for a high-stakes meeting on Thursday, amid growing trade tensions between the two. Relations between the two world powers have been strained in recent years, with Washington and Beijing imposing tit-for-tat trade tariffs topping 100 percent against each other this year, the US restricting its exports of semiconductors vital for artificial intelligence (AI) development and Beijing restricting exports of critical rare-earth metals which are vital for the defence industry and also the development of AI, among other issues. On the sidelines of the Asia-Pacific Economic Cooperation (APEC) summit in Gyeongju, South Korea, on Wednesday, Trump said an expected trade deal between China and the US would be good for both countries and "something very exciting for everybody".
As Trump Weighs Sale of Advanced A.I. Chips to China, Critics Sound Alarm
As President Trump flew to South Korea on Wednesday to prepare for a summit with the Chinese leader, Xi Jinping, he made some remarks that set off alarm bells among Washington officials concerned about America's rivalry with China. "We'll be speaking about Blackwell," Mr. Trump said of his meeting with Mr. Xi, referring to the most advanced artificial intelligence chip from the U.S. chipmaker Nvidia. Mr. Trump called the technology a "super duper chip"; complimented Nvidia's chief executive, Jensen Huang; and declared, "We're about 10 years ahead of anybody else in chips." Mr. Trump's comments signaled a major potential change for U.S. policy that many Washington officials warn poses a national security risk. Selling such advanced A.I. chips to China is currently banned, and U.S. officials have worked for years to restrain Beijing's access to the cutting-edge technology.
This drone's wingspan rivals a 737--but it's lighter than a NFL linebacker
This drone's wingspan rivals a 737--but it's lighter than a NFL linebacker It could deliver internet to remote areas...or quietly watch us from the stratosphere. Radical's Evenstar solar-powered drone has a 120-foot wing span and weighs just 240 pounds. Breakthroughs, discoveries, and DIY tips sent every weekday. Back in the mid-2010s, some of the world's biggest tech companies were racing to launch lightweight, solar-powered drones to hover above remote areas and beam down internet connectivity. Meta (then called Facebook) and Google, the two companies most heavily investing in the technology at the time, abruptly exited the space following a series of mishaps.
The Microsoft Azure Outage Shows the Harsh Reality of Cloud Failures
The second major cloud outage in less than two weeks, Azure's downtime highlights the "brittleness" of a digital ecosystem that depends on a few companies never making mistakes. Microsoft's Azure cloud platform, its widely used 365 services, Xbox, and Minecraft started suffering outages at roughly noon Eastern time on Wednesday, the result of what Microsoft said was "an inadvertent configuration change." The incident--which marks the second major cloud provider outage in less than two weeks--highlights the instability of an internet built largely on infrastructure run by a few tech giants. Microsoft's problems specifically originated from Azure's Front Door content delivery network and emerged just hours before Microsoft's scheduled earnings announcement. The company website, including its investor relations page, was still down on Wednesday afternoon, and the Azure status page where Microsoft provides updates was having intermittent issues as well.
A tiny nearby galaxy is home to a shockingly enormous black hole
One of the Milky Way's smallest galactic neighbours seems to have a supermassive black hole at its centre, upending assumptions that it was dominated by dark matter A nearby galaxy once thought to be dominated by dark matter seems to have a surprise supermassive black hole at its centre. Segue 1 is barely a galaxy, with only about 1000 stars compared to the Milky Way's hundreds of billions, and yet it appears to be home to a black hole about 10 times as massive as all its stars combined. Segue 1 and other similar dwarf galaxies do not have enough stars to provide the gravity needed to hold them all together. To solve that problem, physicists have long assumed they were chock-full of the mysterious substance called dark matter, which we can't see but that could generate the extra gravity. So when Nathaniel Lujan at the University of Texas at San Antonio and his colleagues began testing computer models of Segue 1, they expected the best-fitting model would be one dominated by dark matter.
