“The ChatGPT maker is in discussions to lift funds at a pre-money valuation of $260 billion, mentioned one of many individuals, who spoke on situation of anonymity to debate personal data. The post-money valuation can be $300 billion, assuming OpenAI raises the total quantity. The corporate was valued at $157 billion in October.”
Cerebras Becomes the World’s Fastest Host for DeepSeek R1, Outpacing Nvidia GPUs by 57x Michael Nuñez | VentureBeat
“The AI chip startup will deploy a 70-billion-parameter model of DeepSeek-R1 working on its proprietary wafer-scale {hardware}, delivering 1,600 tokens per second —a dramatic enchancment over conventional GPU implementations which have struggled with newer ‘reasoning’ AI fashions.'”
Stem Cells Used to Partially Repair Damaged Hearts John Timmer | Ars Technica
“Though the Nobel Prize for induced stem cells was handed out over a decade in the past, the therapies have been sluggish to comply with. In a brand new paper printed within the journal Nature, nonetheless, a bunch of German researchers is now describing exams in primates of a technique of repairing the center utilizing new muscle generated from stem cells.”
DeepSeek Mania Shakes AI Industry to Its Core Emanuel Maiberg | 404 Media
“If these new strategies give DeepSeek nice outcomes with restricted compute, the identical strategies will give OpenAI and different, extra well-resourced AI firms even larger outcomes on their enormous coaching clusters, and it’s doable that American firms will adapt to those new strategies in a short time. Even when scaling legal guidelines actually have hit the ceiling and big coaching clusters don’t must be that big, there’s no cause I can see why different firms can’t be aggressive underneath this new paradigm.”
Boom’s XB-1 Becomes First Civil Aircraft to Go Supersonic Sean O’Kane | TechCrunch
“It cleared Mach 1 and stayed supersonic for round 4 minutes, reaching Mach 1.1. Take a look at pilot Tristan Brandenburg broke the sound barrier two extra instances earlier than receiving the decision to convey the XB-1 again to the Mojave Air & House Port. The supersonic flight comes eight years after Growth first revealed the XB-1. It’s a small model of the 64-passenger airliner Growth ultimately desires to construct, which it calls Overture.”
Waymo to Test in 10 New Cities in 2025, Starting With Las Vegas and San Diego Andrew J. Hawkins | The Verge
“This yr, the theme is ‘generalizability’: how properly the autos adapt to new cities after having pushed tens of tens of millions of miles in its core markets of San Francisco, Phoenix, and Los Angeles. Ideally, the corporate is attempting to get to a degree the place it may possibly convey its autos to a brand new metropolis and launch a robotaxi with a minimal quantity of testing as a preamble.”
DeepSeek’s Safety Guardrails Failed Every Test Researchers Threw at Its AI Chatbot Matt Burgess | Wired
“[On Friday], safety researchers from Cisco and the College of Pennsylvania [published] findings exhibiting that, when examined with 50 malicious prompts designed to elicit poisonous content material, DeepSeek’s mannequin didn’t detect or block a single one. In different phrases, the researchers say they had been shocked to attain a ‘one hundred pc assault success fee.'”
Useful Quantum Computing Is Inevitable—and Increasingly Imminent Peter Barrett | MIT Know-how Overview
“Nvidia CEO Jensen Huang jolted the inventory market by saying that sensible quantum computing remains to be 15 to 30 years away, on the similar time suggesting these computer systems will want Nvidia GPUs to be able to implement the mandatory error correction. Nevertheless, historical past reveals that sensible individuals are not immune to creating errors. Huang’s predictions miss the mark, each on the timeline for helpful quantum computing and on the position his firm’s know-how will play in that future.”
With Successful New Glenn Flight, Blue Origin May Finally Be Turning the Corner Eric Berger | Ars Technica
“‘I’d say, “Keep tuned,”‘ [Bezos] mentioned. ‘That is the very starting of the House Age. When the historical past is lastly written lots of of years from now, the Nineteen Sixties shall be a sure form of starting, and [there were] definitely unimaginable accomplishments. However now we’re actually getting began. That was form of pulled ahead from its pure time, the house race with the Soviets. And now’s the time when the actual motion, the form of golden age of house, goes to occur. It is nonetheless completely day one.'”
JWST Shocks the World With Colliding Neutron Star Discovery Ethan Siegel | Large Suppose
“After we examined the remnant of [a 2017 neutron star collision] spectrally, we found an infinite variety of heavy components, indicating that the heaviest components had been possible produced by these cataclysms. In on a regular basis since, we’ve by no means seen one other such occasion immediately, throwing the concept that neutron star collisions make the heaviest components into doubt. However due to JWST, the concept is again on the desk as our #1 possibility.”
Chatbot Software Begins to Face Fundamental Limitations Anil Ananthaswamy | Quanta Journal
“Scientists have had some successes pushing transformers previous these limits, however these more and more appear like short-term fixes. If that’s the case, it means there are basic computational caps on the skills of those types of synthetic intelligence—which can imply it’s time to think about different approaches.”
