this is actually incredible a full body ultrasound scanner that takes 60 seconds instead of spending an hour in an MRI tube, without radiation, hospitals or a $2000 bill soon you’ll just walk into a health spa, order a coffee, step into the pod, and walk out with a 3D map of your body the future is finally starting to look like the future

@sethbannon People are angry because they literally programmed the model to sabotagge people working in llm research. It's cartoonishly evil behavior, they are literally everything they fear other companies would become.

The backlash to Anthropic's limited Mythos/Fable rollout is bizarre. For years, an argument against AI regulation has been: "Trust companies to do the right thing." Anthropic makes a decision that costs it money to ensure safety and suddenly that's unacceptable?

@Phrankensteyn @Jeklundy they run the chips hotter than normal to reduce radiator size masively since the ratio of temperature delta and radiator area needed scales veru quickly

My last few sentences maybe. Additionally, my assumption that the radiator surface panel needs to be 50° C. So assuming most of the collected heat of the solar panels get radiated away which will happen in this design, x.com/SawyerMerritt/… only the power that will end up as heat, too needs additional radiators. The 110 m² seem to be double sided here. So total surface is 220 m². Putting the 120 kW, the 220 m² and the 0.9 emissivity in the formula (Prad = e * sigma * A * T^4), we get the following: (120.000 / (0.9 * 5.67*^10^-8 * 220))^(1/4) = 322 K or 48° C So it does make sense. And it seems, my estimate of 50° C surface temperature wasn't that wrong...

SpaceX has just officially unveiled its AI1 satellite, the first generation of its AI satellite. Overall Specs: • 150 kW peak compute payload • 120 kW average compute payload • 70 kW per ton • Compute provider interchangeable Dimensions: • Wingspan: 70 meters • Deployed height: 20 meters Thermal System: • 110 m² deployable liquid radiator • Redundant pumping loops • Integrated micrometeoroid shielding • Deployable liquid radiators Solar Power System: • 150 kW solar array • 250 W/m² • SpaceX-manufactured solar technology from Bastrop, Texas Architecture: • Centralized compute module • Large deployable solar arrays • Deployable liquid-radiator thermal management system • AI-focused compute satellite design ("AI1 satellite") Elon: "The AI satellite is much simpler than a Starlink satellite. The AI satellite is essentially a lot of solar cells, you still need some laser links, but you don't have all of the super complex antennas that you have on a Starlink satellite. The easier one to design for is the AI satellite. It's bigger. A lot of this is technology we've already made with the Starlink V3 satellites."

Ok, this is kinda funny. Just quick surface math: For 1 kW continuous power in space you need ~4 m² solar panels. This power will ~100% end up as heat. Additionally, we have ~4.6 kW solar heat not transformed into power. Good operating temperatures for computer chips are 80° C. The space background temperature is 3 Kelvin or -270° C, so basically zero. Let's apply Stefan & Boltzmann: Radioation power (Prad) = emissivity (e) * Stefan-Boltzmann constant (sigma) * surface (A) * temperature^4 (T) Let's assume, we work in the shadow of the solar panels for the radiators with e = 0.9 and a target temperature at 50° C at the radiator surface (should be a reasonable delta to the chip surface for heat transport). The formula then is: Prad/ (e * sigma * T^4) = A 50° C = 327.15 K Applying numbers: 5600 W / (0.9 * 5.67*10^-8 W/(m²*K⁴) * 327.15^4) = 9.58 m² So we need about 10 m² of radiators in the shadow of the solar panels. That's a 2*2.5 m² surface assuming we radiate to both directions. Should be doable. Especially considering that the solar heat of the solar panels would pass through parallel to the radiators, so the actual heat that needs the radiators is likely much lower and closer to the power actually used. The radiator doesn't have to be a plate. Could be a cylinder, too. So, yeah, I think I have an idea how to cool a computer chip in space. And if I have it, SpaceX might have it, too.

@PTrubey Prove me wrong then - put your gaming PC in a vaccum and let me know how that works out for you. 👍 ill even let you keep the CPU cooler attached 😂

@peterrhague Dumping something like 120kW of heat with 100-200 square meter radiators seems doable. But that is per satellite and for datacenter scale one needs quite many of these. How will the comms work? Or is the idea to only serve small(ish) clusters for now?

Yes, the thing about your thermos flask is that the outer wall is a 2.8K 🙄 Honestly, how many random creators think they’ve outsmarted the thermal engineers at SpaceX who have successfully flown 10k Starlinks without frying them?
JerryRigEverything@ZacksJerryRig

You know the reason your Stanley or Hydroflask is so good at keeping your water cold is because there's a vacuum inside the walls of the thermos. Heat can't conduct in a vaccum. And "radiated" heat is ineffective at the temperatures processors operate at. This satellite will be like plugging in your gaming PC without a CPU cooler. It'll be dead in minutes.

@skdh @noillypratt1 but it literally does?? it addresses all those problems. If they get starship working reliably then it becomes obvious actually. This will be the most painfully obvious move after they do it.

I don't think anyone says it's impossible to put a data centre into space. I mean, look, we ALREADY have satellites running on solar doing compute. The question is whether it makes financial sense given the current technology. x.com/yatharthmann/s…

Elon Musk lies in bed casually scrolling through X. Suddenly he snaps upright: "Oh no! Space is a vacuum!" Sweating in panic, he calls his team. "Cancel the data centre satellites immediately! I'm about to waste billions!" "Why didn't anyone at SpaceX think of this?"

Not quite. Elon wanted the non-profit to become part of Tesla. They declined. So they preserved the non-profit (that Elon wanted to acquire) and spun out a for-profit it would own. The non-profit is now one of the most well-funded charities in the world and owns a substantial stake in the OpenAI for-profit.

@BenjaminDEKR @petrroyce Bro the only reason we use CLI's instead of cursor is because you can't use the $200 plans from the labs on Cursor and it ends up costing like 10x more, that being said Cursor is still the best.

It is interesting that SpaceX / xAI felt the need to acquire Cursor Why not just build their own? Actually, wasn't Grok Code / other upcoming Grok projects supposed to be this? Grok 5 is supposed to be AGI, then isn't building an AI agentic code IDE in a few months easy?
