ChatGPT is testing disruptive Study Together feature

OpenAI's "Study together" mode has been spotted in the wild, and it could help students prepare for exams directly from ChatGPT. We don't have the details yet, but references to ChatGPT Study Mode were first spotted in May, and testers noticed it widely earlier today. The Study together mode, which doesn't work right now, might allow students to either invite their friends to study on ChatGPT or have the AI act as a companion. We just don't know how it works yet, but it could disrupt the educ

I don't think AGI is right around the corner

“Things take longer to happen than you think they will, and then they happen faster than you thought they could.” - Rudiger Dornbusch I’ve had a lot of discussions on my podcast where we haggle out timelines to AGI. Some guests think it’s 20 years away - others 2 years. Here’s where my thoughts stand as of June 2025. Continual learning Sometimes people say that even if all AI progress totally stopped, the systems of today would still be far more economically transformative than the internet.

More than 1 in 5 Show HN posts are now AI-related, get > half the votes/comments

More than 1 in 5 Show HN posts are now AI-related, but get less than half the votes or comments. _ The idea for this article didn't exist in my brain before this morning. But there I was, scrolling the New page and even more tired of all the AI-related Show HN posts than usual. I was confident that their numbers were multiplying and wanted proof. Exactly how much more AI crap is on my lawn compared to last year? Full disclosure: I'm not a data guy. Everything below was off the top of my head. N

This Is the Cheapest Apple Watch Ever, Amazon Is Going Completely Nuts for Prime Day

Apple has no true competition in the smartwatch world, especially if you’re an iPhone user. While there are a few different models to choose from, the most affordable entry into the Apple Watch universe is the SE version. With its already attractive price and a special Prime Day discount on Amazon, you’re looking at a deal that’s hard to beat: Right now, the Apple Watch SE (2nd Gen) GPS 40mm is available for just $169, down from its usual $249. That’s an all-time low price and it is equal to ma

Bitcoin Bought in 2011 Suddenly Springs to Life After 13 Million Percent Increase In Value

Two Bitcoin wallets that remained untouched for more than a decade just sprang back to life — and whoever owns them is now filthy rich in crypto. As MarketWatch reports, each Bitcoin was worth just 78 cents back when the unknown buyer purchased 20,000 tokens in 2011 for just under $16,000. Due to the digital currency's inexorable rise over the subsequent years, the extremely patient owner of the two "Sleeping Beauty" wallets where the Bitcoin was stored now holds more than $2 billion worth — a

Apple Didn’t Approve, but Amazon Is Clearing Out AirPods Pro 2 at a Record Low for Prime Day

AirPods Pro 2 are in stores just a year but already they set the benchmark by which other wireless earbuds with active noise cancellation are judged. On the subject of sound quality, nothing else comes close to holding a candle right now. Normally these earbuds cost $249, but Amazon is offering them over 30% off early Prime Day, reducing the price to as low as $169. This deal is for everyone (and not just Prime members) and it is a rarity for an Apple device. Remember, Apple never really offers

Just Ask for Generalization (2021)

Generalizing to what you want may be easier than optimizing directly for what you want. We might even ask for "consciousness". This blog post outlines a key engineering principle I’ve come to believe strongly in for building general AI systems with deep learning. This principle guides my present-day research tastes and day-to-day design choices in building large-scale, general-purpose ML systems. Discoveries around Neural Scaling Laws, unsupervised pretraining on Internet-scale datasets, and o

QSBS Limits Raised

On June 16, 2025, the Senate Finance Committee released its own version of proposed legislation following the House’s passage of the “One Big Beautiful Bill Act” (H.R. 1). While the House bill did not introduce any changes to Section[1] 1202 for “qualified small business stock” (QSBS), the Senate Finance proposal introduces significant expansions of the tax benefits of QSBS acquired after the date of the enactment of the final legislation. Summary of Current Law The QSBS exemption allows nonco

Google faces EU antitrust complaint over AI Overviews

In Brief A group known as the Independent Publishers Alliance has filed an antitrust complaint with the European Commission over Google’s AI Overviews, according to Reuters. The complaint accuses Google of “misusing web content for Google’s AI Overviews in Google Search, which have caused, and continue to cause, significant harm to publishers, including news publishers in the form of traffic, readership and revenue loss.” It also says that unless they’re willing to disappear from Google searc

Inside a Utah desert facility preparing humans for life on Mars

Hidden among the majestic canyons of the Utah desert, about 7 miles from the nearest town, is a small research facility meant to prepare humans for life on Mars. The Mars Society, a nonprofit organization that runs the Mars Desert Research Station, or MDRS, invited CNBC to shadow one of its analog crews on a recent mission. "MDRS is the best analog astronaut environment," said Urban Koi, who served as health and safety officer for Crew 315. "The terrain is extremely similar to the Mars terrain

Wildly Beautiful and Rare "Red Sprite" Flare Seen on Earth From Orbit

Red Sprite NASA astronaut Nichole Ayers, currently stationed on board the International Space Station, shared an incredible image of a sprite — a rare weather phenomenon that's triggered high above the clouds by "intense electrical activity in the thunderstorms below." The image shows the rare electrical discharge in the shape of a starkly red, upended umbrella, hovering high over a brewing storm, like some sort of occult tower from "Lord of the Rings." "Just. Wow," Ayers tweeted. "As we went

Is It Time to Stop Protecting the Grizzly Bear?

This story originally appeared on Vox and is part of the Climate Desk collaboration. In the early 1900s, long before smartphones and selfie sticks, tourists flocked to Yellowstone National Park—not for the geysers or scenery, but for a grotesque show: a nightly spectacle of grizzly bears raiding cafeteria scraps from open-pit landfills like desperate, starving pirates. The bears were in dangerous proximity to humans: Hungry bears tore at open car windows. Tourists posed a little too close with

ChatGPT Deep Research tests new connectors for more context

ChatGPT Deep Research, which is an AI research tool to automate research, is getting support for new connectors (integrations), including Slack. Deep Research is an AI agent that automates research for you. You just need to give it a brief prompt with all the necessary details, and it will crawl the internet to write a research paper. As spotted by Tibor on X, ChatGPT has references to a new connector called 'Slack.' Once integrated, ChatGPT can crawl your Slack messages and use them in the c

Chasing Lost Languages

If humans have been talking for 200,000 years—for most of our species’ existence, that is—then an estimated half a million languages might have been spoken in all. To put that number in perspective, around 7,000 languages are spoken today. And because writing was only invented about 5,000 years ago, the vast majority of those half a million languages are lost to us, having been spoken in a preliterate world and died before they could be recorded. That’s half a million distinct systems of knowled

Ask HN: Worth leaving position over push to adopt vibe coding?

My company is increasingly pushing prompt engineering as the single way we "should" be coding. The CEO & CTO are both obsessed with it and promote things like "delete entire unit test file & have claude generate a new one" rather than manually address test failures. I'm a 'senior engineer' with ~5 years of industry experience and am considering moving on from this company because I don't want 1. Be pushed into a workflow that will cause my technical growth to stall or degrade 2. Be overseeing

Supergiant’s latest Hades II patch is likely its last before launch

Despite it having upward of 61,000 reviews on Steam, Hades II isn’t actually out yet. The sequel to Supergiant Games’ hugely successful roguelite dungeon crawler has been in early access on PC for over a year, and even the early builds were extremely polished and content-rich for what is still a work-in-progress game. But we (and Switch owners) have been waiting patiently for that 1.0 release date, and it looks like it might be just around the corner, with Supergiant confirming that the latest U

What the Hell Just Happened to Spider-Gwen?

Marvel Comics is no stranger to a bit of brand synergy and consolidation. The more characters break out into the mainstream beyond the readership of comics, the more their comics counterparts are sanded down and chopped and changed to eventually better accommodate the potential for audiences who are aware of them through adaptation to go to the comics and find familiar fare. This has been especially true as the shadow of the MCU grew ever larger, reshaping characters and realigning destinies the

This Is Why Tesla’s Robotaxi Launch Needed Human Babysitters

Whether due to consumer backlash or an aging EV lineup, or both, Tesla sales have again seen a global plunge, this time 13 percent last quarter compared to the previous year—proof that the electric automaker hasn’t yet turned around a dismal year that saw public opinion of controversial CEO Elon Musk plummet. It could mean Tesla faces a second straight year of falling sales. And yet: Tesla is still the world’s most valuable automaker by market capitalization, worth some $990 billion. At least s

The US dollar is on track for its worst year in modern history

The US dollar is on track for its worst year in modern history and may not be done falling yet. The greenback is down more than 7% this year and Morgan Stanley predicts it could fall another 10%. A weaker dollar could make US exports more competitive, boosting Trump’s plan to rebalance US trade, but makes imports more expensive, adding to the sting of tariffs. The question ahead is whether the dollar doesn’t just lose its value, but its role at the center of the global financial system. So far,

The Person in Charge of Testing Tech for US Spies Has Resigned

The head of the US government’s Intelligence Advanced Research Projects Activity (IARPA) is leaving the unit this month to take a job with a quantum computing company, WIRED has learned. Rick Muller’s pending departure from IARPA comes amid broader efforts to downsize the United States intelligence community, including the Office of the Director of National Intelligence (ODNI), which oversees IARPA. A person familiar with Muller’s plans confirmed to WIRED his departure from IARPA. Born during

Leaked renders offer an early look at Samsung’s official Galaxy Z Flip 7 cases

Evan Blass TL;DR Samsung may offer four official cases and a screen protector for the upcoming Galaxy Z Flip 7. The clamshell foldable could get a basic clear case with a grip, a clear magnet case, a silicone case in four colorways, and a Kindsuit case in three finishes. Unlike the Galaxy Z Fold 7, the cheaper foldable may not get an official carbon fiber case. Hot on the heels of a leak revealing Samsung’s official Galaxy Z Fold 7 cases, a new report has unveiled the full lineup of accessor
