Persona-assigned Large Language Models (LLMs) can adopt diverse roles, enabling personalized and context-aware reasoning. However, even minor demographic perturbations in personas, such as simple pronoun changes, can alter reasoning trajectories, leading to divergent sets of correct answers. Instead of treating these variations as biases to be mitigated, we explore their potential as a constructive resource to improve reasoning robustness. We propose CHOIR (Collaborative Harmonization fOr Inference Robustness), a test-time framework that harmonizes multiple persona-conditioned reasoning signals into a unified prediction. CHOIR orchestrates a collaborative decoding process among counterfactual personas, dynamically balancing agreement and divergence in their reasoning paths. Experiments on various reasoning benchmarks demonstrate that CHOIR consistently enhances performance across demographics, model architectures, scales, and tasks - without additional training. Improvements reach up to 26.4% for individual demographic groups and 19.2% on average across five demographics. It remains effective even when base personas are suboptimal. By reframing persona variation as a constructive signal, CHOIR provides a scalable and generalizable approach to more reliable LLM reasoning.

Breakthroughs, discoveries, and DIY tips sent every weekday. Apple announced the upcoming iOS 26 software for iPhone back on June 9, 2025, with a revamped Liquid Glass look and a host of new features. Those additions include live translations, AI-powered visual search, a new Games app, and better security, and you can read about those new features here. Almost straight after the update was announced, Apple started a beta program for developers and early adopters. Since then, we've seen even more upgrades added to the iOS 26 that weren't mentioned during the announcement.

Did you know that computers have artificial intelligence now? We've been subjected to an absolute avalanche of marketing touting AI from seemingly every tech company, from Microsoft and Nvidia to laptop makers and even thermal paste sellers. Well if you've somehow avoided the AI blitz, possibly by using a Chromebook, you're about to get it in spades from Google. The company has been pushing its Gemini (nee Bard) AI tools into most of its high-profile products, most notably Chrome and Android. Now Chromebook Plus, Google's higher tier of ChromeOS laptops revealed last year, are slated to be Google's flagship platform for the best and brightest of Gemini, with a few tools and options that aren't available elsewhere.

It's been just over a year since the launch of ChatGPT sent the world AI-crazy. So it's no surprise that tech giants now want to integrate and promote the artificial intelligence capabilities in all their new gadgets - from laptops to TVs. But it's smartphones that look set to be one of the biggest AI battlegrounds. Apple's next iPhone is heavily rumored to have loads of new AI-powered features. Samsung and Google have also gone all-in on AI in phones, with their latest S24 Ultra and Pixel 8 Pro (out this year and late last year respectively) both being marketed heavily on their AI capabilities.

CyberGuy explains how Walmart is using artificial intelligence to enhance the shopping experience. You know that feeling when you unbox a new Mac for the first time? You can't help but admire how sleek and smooth it looks and how bright and beautiful it glows when you turn it on. And don't get me started on those crisp and clean keys that make typing a breeze. Before we jump into all the cool stuff you can do with your Mac, there are some important things you need to set up first.

Motorola showcased some wacky concepts at Lenovo Tech World '23 that may or may not ever see the light of day. The smartphone maker (a subsidiary of Lenovo since 2014) unveiled an "adaptive display" prototype that can be rolled into a phone, stand or smart bracelet. In addition, the company highlighted several developmental AI-powered features for the Lenovo devices you can already buy. The display concept is a rollable smartphone with an FHD pOLED display. The prototype "can be bent and shaped into different forms depending on users' needs," the company wrote in its announcement blog post.

Since the original Pixel, the special sauce for all of Google's phones has been its software. We've seen this throughout the years in its cameras with things like HDR processing and Google's potent Night Sight mode. But on the Pixel 8 and Pixel 8 Pro, thanks to the new Tensor G3 chip and focus on machine learning, it feels like Google's latest flagship phones are taking some of the buzz from the recent AI hype cycle and turning it into tools you'll actually want to use. Their corners are a touch more rounded and Google deleted the small chin below the screen by making its bezels a uniform size all around. One notable change is that the Pixel 8 has shrunk a bit to a 6.2-inch screen (down from 6.3 inches on the Pixel 7).

In the days leading up to its annual software conference, Google executives were unusually excited about … wallpaper. Wallpaper that's generated by artificial intelligence after tapping a few prompts on your phone screen. "Generative AI" is the key phrase here. It's the category of artificial intelligence that tech companies both big and small are hanging their futures on right now. Alphabet-owned Google is one of the pioneers in this space; as Google executives like to remind people, the "T" in OpenAI's ChatGPT actually refers to transformer technology that Google introduced back in 2017. And Google has been working on human-like chatbot technology for years.

To say the Google I/O 2023 keynote was packed would be an understatement. Google unveiled a flurry of new Pixel devices as well as the latest versions of Android and other platforms. It also won't surprise you to hear that AI was everywhere -- this was Google's big chance to compete with OpenAI's ChatGPT. Don't worry if you missed something during the event, though, as we've got all the biggest announcements from the event. There's no doubt that the (previously confirmed) Pixel Fold was the star of the show.

When Android 14 arrives later this year, it will bring new customization features to Google's mobile operating system. On Wednesday at the company's I/O developer conference, Android chief David Burke showed off a handful of new features for creating custom wallpapers. The tools build on the Material You design system Google introduced in 2021 by allowing users to create a custom wallpaper by picking a few of their favorite emojis. The creation tool allows you to add up to 14 emojis to a single wallpaper. You can then pick a pattern and a color to bring everything together.
