This is a great idea. Developability is one of the tasks holding back AI driven therapeutics. Would be very curious to see which startups win this.

I wonder how much better the UK’s AI startup scene would be if they banned @GoogleDeepMind from issuing non competes. These are illegal in California and probably a big reason there are multiple AI companies there.
“I wanted to organize all the world’s information for real,” Bryk said. That vision was compelling enough to Fenton that it inspired Benchmark to break its own rules. The firm usually invests about $15 million at the Series A stage. With Exa, it’s written a $50 million check in…
There's one week until YC Demo Day, and I'm launching new updates to @ghostship_ai every day. Today, I'm launching Ghostship playground that allows us to find bugs in your production ready links. Next week on Wednesday, September 10th right after YC Demo Day, I'm excited to…
Last month's hearing in Boston on self-driving car was like a parody of the attitudes @DKThomp and @ezraklein critiqued in Abundance.
🚀 @trace_so (YC S25) just pulled off a grand slam on @ProductHunt — voted #1 Product of the Month, Week, and Day. Since our PH launch last Monday, we’ve already sold 62 Pro subscriptions, onboarded 17 new startups, and automated 5,800+ tasks across @SlackHQ, @GoogleWorkspace,…
S25 Demo Day won't be the usual YC Demo Day. 11 years after Cruise's (W14) demo day, we're doing the same for excavators. We're going to have a real excavator capable of remote teleop and autonomy. And of course, we're naming this version: Kyle🧡
fascinating thing as AI has gotten more real is somehow IBM's US Open AI ads have gotten even more insufferable
The top open source LLMs have some interesting differences in architecture and training methods. I read all of the papers in depth to break them down in this video (and my debut on the YC YouTube 😅) Check it out and let me know what you think!

Congrats to @PKrishnaSuresh & @raghavarora108 on launching! These are two of the most impressive founders I've ever met, redefining what I think is possible for a pair of young founders to pull off. This is one to watch.

After years of chats, some friends from my MD/PhD program and I launched a nerdy blog about science + medicine: emergentpropertiesblog.com We explore everything from evolutionary theory to big data in science. @kaitavjeet just posted on the power of abstraction in biology 🧫
There are many exciting new research labs to build, and @induction_labs is one I've enjoyed working with this batch. These founders are very impressive and I'm pumped to see their newest results training their own computer use models.
this finally happened. I onboarded @mintlify’s engineering team. collison installation ft. @skeptrune @handotdev
