@dsp_ @felixrieseberg I am also curious about this
Within ~2 years, there might be >0.5 Manhattan Projects worth of philanthropic $$$ to spend on the biggest challenges, like cyber or biodefense. @nanransohoff is right: the hard part is finding enough good organizations to spend the $. You should build one!
New blog post: The third wave of American philanthropy Hundreds of billions of dollars in new philanthropic capital will soon become liquid. The OpenAI Foundation holds 26% of OpenAI, worth about $220B at today’s valuation. Anthropic’s seven co-founders have pledged to give away
it does seem that this time, unlike others, it is fair to characterize it all as ‘late stage capitalism’
@mattyglesias Soon — “why are we seeing pet food targeted towards humans?”
@mitsuhiko Nate parrott is an impressive guy
@trq212 @nateparrott I feel this so strongly
@LincolnRestler This is bad policy. Please do not cap the fees of citibike and make it so they can’t operate. Famously nyc in the past capped subway fares of private companies which bankrupted the companies, and then the fares rose anyway when the city took over the companies.
@joshwoodward @rakyll Always hustling!
Opus 4.7 uses more thinking tokens, so we've increased rate limits for all subscribers to make up for it. Enjoy!
@dioscuri Hey, congrats! That’s awesome
@katelyn_lesse @mc_anthropic Congrats Katelyn!
Oh, and one more thing:
Introducing Claude Managed Agents: everything you need to build and deploy agents at scale. It pairs an agent harness tuned for performance with production infrastructure, so you can go from prototype to launch in days. Now in public beta on the Claude Platform.
@neilhtennek @trq212 Kenneth noooooo
@SamEshaghoff Very cool visualization, nice job!
Mistakes happen. As a team, the important thing is to recognize it’s never an individuals’s fault — it’s the process, the culture, or the infra. In this case, there was a manual deploy step that should have been better automated. Our team has made a few improvements to the automation for next time, a couple more on the way.
