Leftism consistently produces poverty, misery, and oppression because it imposes a zero-sum frame in which individual success or advancement must necessarily be at others expense
People literally just want to be able to afford to eat and heat their homes. Nobody wants this.
Rainbrand turns your brand into code and puts it in a repo so that your agents can create websites, decks, and videos that look and feel exactly the way you want them to. Ray is betting that marketing teams will soon need their own devtools. I think he's right.
Introducing Rainbrand, the brand layer for agents. ⇢ ingest brand context from anywhere ⇢ turn it into a machine-readable brand system ⇢ use it across agents and products We’re building brand infrastructure for a world of agents.
The ideal outcome for science isn't a couple of labs using proprietary models and millions of dollars to crack trophy problems, it's to have millions of AI-aided human scientists who follow their curiosity and become way more ambitious
String theory is what happens when an intelligent system is starved of sensory input and starts hallucinating. Intelligence needs grounding. For this reason, intelligence is practically never the bottleneck to solving impactful problems. The bottleneck is iterated contact with reality.
Huge day for us today: @resend is now billing through Autumn This is a full circle moment. @johnyeo_ using the Resend API is actually what inspired us to build a devtool in the first place. They set the standard for product quality and user experience. They moved to @autumnpricing because they needed a single, reliable engine to monetize all the new products they ship, and their growing enterprise motion meant a lot more custom contracts to manage. Resend is the most downloaded email API in the world and growing like crazy. We’re super proud they chose us to meter, enforce and bill their highest-volume workloads.
Introducing DeepRSI, a new industry standard for measuring recursive self-improvement. On preexisting benchmarks, tasks are contributor-based and short-horizon (~12 hrs). In DeepRSI, we push agents to work 48 hours on ML tasks actually derived from ongoing proprietary research.
“What are you going to be for Halloween?” 2yo, without missing a beat: “A costume!”
Introducing Maritime (YC F26): the cloud platform for running billions of AI agents We give startups the infrastructure to deploy, manage, and scale their agents, each with its own computer Hosting starts at $1/agent/month
we should be more ambitious
Some people are dunking on this, but IMHO THIS is the way that science publications should be done. Post-publication corrections and modifications should be THE norm, not an exception. Software developers had it right all along. We need to stop treating research publications as settled scriptures.
We've updated our GitHub math repo with 6 new Lean formalizations, 19 modifications, and 3 withdrawals. The repo now has ~42% top-line results formalized. We will continue to update the repo with new formalizations and with any errata we notice. github.com/openai/math/bl…
I hope the next big lab math drop is just a PR on this repo.

Excited to announce that @trydatabuddy is part of the YC F26 batch! Collecting data is easy, understanding it isn’t. That's why we're building Databuddy, the most comprehensive intelligence platform that combines all of your analytics and context into informed business insights and investigates your product issues as they happen in real-time If you're tired of spending hours in your posthog dashboards trying to make sense of your data, this is for you
This document is going to be an assigned reading in college classes that cover this moment in time, there's a lot happening in a few paragraphs... ahmath.org/statements
@internetphysics @matt_slotnick We're smarter than animals, so we can debate what is true about reality without any real skin in the game
Amazon banning agents is the first opportunity I've seen since Amazon was founded for a startup to create an Amazon competitor. People will want agents to buy stuff for them. It will be one of the main use cases. And they won't want to use some Amazon-supplied agent to do it.
@sean2bz I worry the nuanced answers on the first point specifically will lead us down a dangerous path. These models are perhaps the greatest tools ever developed, but they are and imo should always remain just that: tools for human empowerment.
The correct answer to “are the models conscious?” is “I don’t care because I am on Team Human, not Team Consciousness”
@i_am_echel0n you may be right but your answer is easily countered and also sidesteps the real question which is what to do if they _are_ conscious. I am answering both at the same time :)
@clairevo ok wait that sounds great is it too late to change teams?
