OpenAI in Talks to for Latest Funding at As much as $300 Billion Value Shirin Ghaffary, Rachel Metz, and Kate Clark | Bloomberg
“The ChatGPT maker is in discussions to lift funds at a pre-money valuation of $260 billion, said one in all the people, who spoke on condition of anonymity to debate private information. The post-money valuation could be $300 billion, assuming OpenAI raises the total amount. 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 version of DeepSeek-R1 running on its proprietary wafer-scale hardware, delivering 1,600 tokens per second —a dramatic improvement over traditional GPU implementations which have struggled with newer ‘reasoning’ AI models.'”
Stem Cells Used to Partially Repair Damaged Hearts John Timmer | Ars Technica
“Although the Nobel Prize for induced stem cells was handed out over a decade ago, the therapies have been slow to follow. In a brand new paper published within the journal Nature, nonetheless, a bunch of German researchers is now describing tests in primates of a technique of repairing the center using recent muscle generated from stem cells.”
DeepSeek Mania Shakes AI Industry to Its Core Emanuel Maiberg | 404 Media
“If these recent methods give DeepSeek great results with limited compute, the identical methods will give OpenAI and other, more well-resourced AI firms even greater results on their huge training clusters, and it is feasible that American firms will adapt to those recent methods in a short time. Even when scaling laws really have hit the ceiling and giant training clusters don’t should be that big, there’s no reason I can see why other firms can’t be competitive under this recent paradigm.”
Boom’s XB-1 Becomes First Civil Aircraft to Go Supersonic Sean O’Kane | TechCrunch
“It cleared Mach 1 and stayed supersonic for around 4 minutes, reaching Mach 1.1. Test pilot Tristan Brandenburg broke the sound barrier two more times before receiving the decision to bring the XB-1 back to the Mojave Air & Space Port. The supersonic flight comes eight years after Boom first revealed the XB-1. It’s a small version of the 64-passenger airliner Boom eventually wants to construct, which it calls Overture.”
Waymo to Test in 10 Latest Cities in 2025, Starting With Las Vegas and San Diego Andrew J. Hawkins | The Verge
“This 12 months, the theme is ‘generalizability’: how well the vehicles adapt to recent cities after having driven tens of hundreds of thousands of miles in its core markets of San Francisco, Phoenix, and Los Angeles. Ideally, the corporate is attempting to get to a degree where it could possibly bring its vehicles to a brand new city and launch a robotaxi with a minimal amount of testing as a preamble.”
DeepSeek’s Safety Guardrails Failed Every Test Researchers Threw at Its AI Chatbot Matt Burgess | Wired
“[On Friday], security researchers from Cisco and the University of Pennsylvania [published] findings showing that, when tested with 50 malicious prompts designed to elicit toxic content, DeepSeek’s model didn’t detect or block a single one. In other words, the researchers say they were shocked to attain a ‘100% attack success rate.'”
Useful Quantum Computing Is Inevitable—and Increasingly Imminent Peter Barrett | MIT Technology Review
“Nvidia CEO Jensen Huang jolted the stock market by saying that practical quantum computing continues to be 15 to 30 years away, at the identical time suggesting those computers will need Nvidia GPUs so as to implement the mandatory error correction. Nonetheless, history shows that good people usually are not resistant to making mistakes. Huang’s predictions miss the mark, each on the timeline for useful quantum computing and on the role his company’s technology will play in that future.”
With Successful Latest Glenn Flight, Blue Origin May Finally Be Turning the Corner Eric Berger | Ars Technica
“‘I might say, “Stay tuned,”‘ [Bezos] said. ‘That is the very starting of the Space Age. When the history is finally written tons of of years from now, the Sixties can be a certain form of starting, and [there were] actually incredible accomplishments. But now we’re really getting began. That was form of pulled forward from its natural time, the space race with the Soviets. And now could be the time when the true movement, the form of golden age of space, goes to occur. It’s still absolutely day one.'”
JWST Shocks the World With Colliding Neutron Star Discovery Ethan Siegel | Big Think
“After we examined the remnant of [a 2017 neutron star collision] spectrally, we discovered an infinite variety of heavy elements, indicating that the heaviest elements were likely produced by these cataclysms. In on a regular basis since, we’ve never seen one other such event directly, throwing the concept that neutron star collisions make the heaviest elements into doubt. But because of JWST, the thought is back on the table as our #1 option.”
Chatbot Software Begins to Face Fundamental Limitations Anil Ananthaswamy | Quanta Magazine
“Scientists have had some successes pushing transformers past these limits, but those increasingly appear to be short-term fixes. If that’s the case, it means there are fundamental computational caps on the skills of those types of artificial intelligence—which can mean it’s time to think about other approaches.”
