Perplexity launches Portable Computer, a local-first AI agent that runs entirely on-device on NVIDIA DGX Spark hardware using compact models like Qwen 3.8 or PPLX 27B, delivering zero token costs for locally processed tasks while still supporting cloud options; it prioritizes privacy by keeping data on-device, with Pro/Max subscribers able to deploy on DGX Spark today and Nemotron 3.5 Lightning/RTX support planned.
Four AI rivals—ChatGPT, Gemini, Claude, and Perplexity—are asked to critique each other, and their responses reveal a landscape of strengths: ChatGPT is the versatile generalist with a strong ecosystem but can sacrifice depth for speed; Gemini excels with live data and Google integration but can be shallow in reasoning; Claude shines in natural, careful writing and long-context reasoning but can be overly cautious; Perplexity is strong for live web search with verifiable citations but isn’t a chat-focused assistant. The takeaway: there’s no universal best; the right tool depends on the task.
With OpenAI ending ChatGPT Atlas, Mac users now have several AI-powered browsing options: a ChatGPT Chrome extension that works in Chromium-based browsers, Perplexity’s Comet, Dia from The Browser Company, Opera Neon, Aside for macOS, and even Safari paired with AI tools like Codex; the piece recommends trying a few to see what’s possible today and notes that OpenAI is moving AI-assisted features into the upcoming ChatGPT desktop app rather than maintaining Atlas.
Perplexity has gifted a small number of Mac Minis to select content creators to showcase its AI-powered Personal Computer, a Mac app that runs across local files, native apps, and the web; the move comes amid a surge in Mac Mini demand tied to AI tools, rising Apple prices, and a growing view of the Mac Mini as a status symbol among power users.
CNN filed a federal lawsuit in the Southern District of New York accusing Perplexity of scraping more than 17,000 CNN stories, photos, and videos to train its AI, infringing CNN’s copyrights and trademarks. The network is seeking damages and an injunction; Perplexity says facts cannot be copyrighted. This is CNN’s first legal action against an AI company and follows other publishers’ licensing deals with the AI firm.
CNN has filed a lawsuit against AI company Perplexity, alleging it unlawfully copied CNN's content after licensing talks failed; the action marks CNN's first AI copyright suit and is part of a broader wave of publisher legal actions aimed at securing compensation as AI tools reuse news content.
IBM and Multiverse Computing demonstrated a quantum-classical hybrid approach that inserts Cayley-parameterized unitary adapters into a frozen Llama 3.1 8B model and runs the training-then-inference cycle on an IBM 156-qubit Quantum System Two. The result is a 1.4% reduction in perplexity with only about 6,000 extra parameters (a tiny, 0.000075% increase), enabling the hybrid model to answer certain questions correctly that the base model got wrong. The work shows a path toward quantum-enhanced AI on real hardware, but faces challenges from quantum noise and the need for future work to encode the entire quantum circuit to push perplexity further with even smaller classical needs.
Perplexity launches a Mac app that extends its hybrid local-cloud AI, Personal Computer, to Pro and Enterprise users, enabling workflow automation across local files and native Mac apps while running tasks on Perplexity’s servers; it requires a subscription, works on macOS 14 Sonoma+ (best on a Mac mini for continuous use), and can operate web tools via the Comet browser with text or voice commands.
Apple has abandoned its net-cash-neutral target, signaling that a major AI-focused acquisition could be in the works to close its AI gap. The move accompanies a broader AI strategy that mixes internal model development with a Google Gemini partnership, suggesting Apple may use debt to fund transformative deals. Analysts spotlight potential targets like Perplexity and Q.ai as signs that larger, inorganic growth could follow under the new leadership as demand for AI accelerates.
A ZDNET tester uses CarPlay to compare ChatGPT and Perplexity AI. ChatGPT excels in conversational tasks, storytelling, and calendar access, while Perplexity handles location-based tasks like driving directions and reminders. Siri remains best for music and basic hands-free calls. The takeaway: ChatGPT provides the stronger in-car chat experience, but both AIs offer useful capabilities and can be used together.
Perplexity CEO Aravind Srinivas argues the iPhone won’t be disrupted by AI, attributing this to Apple’s on‑device AI processing and strong privacy protections. He says the iPhone’s role as a personal hub for wallets, health data, photos, and communication makes it resistant to AI replacement, suggesting Apple could stay ahead in the AI race as AI improves.
Tom's Guide pits ChatGPT vs. Perplexity in a five-prompt AI Madness face-off spanning real-world decision making, breaking news, creativity, deep reasoning, and daily decision-making. Across the rounds, ChatGPT wins for decision-making, creativity, and deep reasoning, while Perplexity earns a win on the breaking-news prompt for current, accurate sourcing (notably Nvidia’s GTC 2026 coverage). In the end, ChatGPT is the overall winner thanks to versatility and nuanced instruction handling, though Perplexity demonstrates strong real-time research strengths.
Samsung's Galaxy S26 initially offered a Hey Plex voice trigger for the Perplexity app, but the first software update appears to remove that option, preventing Hey Plex from launching Perplexity. The phone now supports only two on-screen assistants via voice (Bixby and Gemini), with no clear explanation for the change and uncertainty about whether the app or the system updated this feature.
Perplexity rolled out Personal Computer, a 24/7 AI agent that runs on a dedicated device on your local network to turn a spare Mac (and potentially a Mac Mini) into a private AI assistant with full access to files and apps, controllable from anywhere. It’s pitched as more secure than rivals with features like an audit trail, the ability to reverse actions, and a kill switch; access is via a waitlist while the service is prepared for broader rollout, and a video demo shows it drafting emails, turning reports into slides, and ranking job candidates for professional use.
A federal judge issued a preliminary injunction blocking Perplexity’s Comet AI browser from placing Amazon orders on user accounts, citing strong evidence of unauthorized access. Perplexity must stop accessing Amazon and destroy any data it obtained, with seven days to appeal, as Amazon continues its lawsuit over the Comet agent-shopping feature.
