🤮 behavior from $PLTR
1/6 Palantir sued 3 of Percepta's employees (including me) last week. They're trying to bully us. We should all be concerned when a $400B+ giant is attacking a 35-person start-up over baseless allegations.

Exciting update: I’ve joined @AnthropicAI as a researcher. The potential to fight disease is core to why I believe we should keep improving AI (for now). Grateful to work on this problem at a company whose philosophy on AI for good resonates deeply with me. Onwards!

Getting a new idea off the ground is tough. A trick: start with a minimum evolvable product. Some thoughts here.

Some counterintuitive thoughts on finding a first user and evolving from there.

So glad someone is doing this -- I have been wondering what the best frontier models are for scientific tool use, v interesting to see the results. Hopefully this inspires frontier labs to optimize against some of these classic comp chem / drug discovery workflows.
The smartest AI agents still panic when given tools, and new ones are churning out of labs faster than anyone can test them. After 7 years at the bench, I left to build BioArena to see which models are doing real work and which ones are just doing PR. https://t.co/JpA1ePP64l

How deep the rabbit hole goes...
New blog post: The bug that taught me more about PyTorch than years of using it started with a simple training loss plateau... ended up digging through optimizer states, memory layouts, kernel dispatch, and finally understanding how PyTorch works!

So proud and excited for my guy!!! Next generation of YC founders don't know how lucky they are.
YC took a bet on me almost 8 years ago and changed my life. The partners we worked with in building Reverie helped us navigate some of our hardest moments. I feel so fortunate to have a job helping the next generation of founders set out on their own incredible adventures.

I just wrote my first blog post, “Everything is Training Data Now.” I noticed myself starting to doubt LLM performance on certain benchmarks due to data contamination / gaming, and wanted to see how real this is. Spoiler alert: there’s a lot of variance across models and labs.

Awesome new offering from Ginkgo Datapoints -- we will price match any ADME service quote you get (including from Chinese or other international vendors). We plan to have the best per-compound pricing out of the gate anyway --our automation at Ginkgo allows best in class
We’re excited to launch a powerful new capability at Ginkgo Datapoints: high-throughput, low-cost ADME profiling—optimized for machine learning from day one. Whether you’re prioritizing small molecules or training predictive models, early access to rich ADME data can

Great read on our journey at Reverie, from SaaS to a bona fide pharma company.
With the start of my first batch as a visiting partner at @ycombinator, this felt like a good time to write my founder story about our journey at @reverielabs. It's a bit of a long one. https://t.co/KWyMxPDdXO

NYT tweeted this to its 55 million followers and it has under 500 retweets - presumably suppressed due to the link out. “John Kelly, Donald Trump’s longest-serving chief of staff, said Trump met the definition of a fascist and would try to govern like a dictator if elected”

Thank you to everyone who has been a crucial part of this journey -- our team, our investors, our partners. I'm so grateful to my family, friends, and partner -- I would never have made it to this point without you. Onwards and upwards, to new adventures!
